Unveiling Hidden Sugars: A Critical Analysis of Maltodextrin as a Polysaccharide Additive in Processed Foods and Its Health Implications

Abstract

Maltodextrin, a polysaccharide derived from enzymatic hydrolysis of starch, is widely used in processed foods due to its multifunctional roles as a thickener, filler, and texturizer. Despite its seemingly innocuous classification as a complex carbohydrate, maltodextrin exhibits a high glycemic index (GI) comparable to or exceeding that of glucose, leading to rapid blood sugar spikes and potential metabolic disruptions. This characteristic, coupled with its ubiquitous use across a spectrum of consumables—from sports drinks and infant formulas to meal replacement bars—raises significant public health concerns.

This paper critically examines maltodextrin’s biochemical structure, functional applications, and regulatory classification, while investigating its metabolic effects, interaction with gut microbiota, and association with chronic conditions such as insulin resistance and inflammatory bowel disease (IBD). The study synthesizes current literature and market data to highlight how maltodextrin often escapes classification as a “sugar” on nutrition labels, allowing it to remain undetected by consumers aiming to reduce sugar intake.

Empirical evidence and survey results further reveal a disconnect between scientific knowledge and consumer awareness, suggesting an urgent need for improved labeling standards and public education. By integrating chemical analysis, literature review, regulatory assessment, and consumer insights, this research underscores the necessity of reevaluating maltodextrin’s role in processed foods. It also calls for the development of transparent food policies and the use of alternative low-GI polysaccharides that align with metabolic health goals.

1. Introduction

1.1. The Evolving Food Landscape and the Rise of Additives

The 21st-century food ecosystem is characterized by a dramatic shift from home-prepared meals toward industrially processed and ultra-processed food products. This transition, driven by globalization, urbanization, and a demand for convenience, has led to a significant increase in the use of chemical and biological additives to improve texture, shelf life, flavor, and nutritional profile. Among these substances, maltodextrin, a starch-derived polysaccharide, has emerged as a ubiquitous ingredient across an extensive range of food categories, including infant formula, protein powders, energy drinks, sauces, flavored snacks, meal replacements, and pharmaceuticals.

Maltodextrin is favored by food technologists for its unique properties: it is odorless, tasteless to mildly sweet, highly soluble, and functions as a bulking agent, stabilizer, fat replacer, and carrier for flavorings and colorants. However, despite its widespread use, maltodextrin remains largely invisible to the average consumer, primarily due to regulatory loopholes that exclude it from being categorized or labeled as sugar, despite its high glycemic potential and metabolic consequences.

1.2. Understanding Maltodextrin’s Classification as a Hidden Sugar

Maltodextrin is produced through partial enzymatic hydrolysis of starch, resulting in a mixture of oligosaccharides with varying chain lengths and Dextrose Equivalent (DE) values ranging from 3 to 20. The higher the DE, the more similar the substance behaves to simple sugars in terms of sweetness and digestibility. Despite being a complex carbohydrate chemically, maltodextrin is rapidly digested and absorbed into the bloodstream, often more quickly than glucose itself. Its glycemic index (GI), depending on its formulation and raw source, typically ranges from 85 to 105—surpassing that of table sugar (GI ~65) and even pure glucose (GI ~100) in some instances.

Yet, in regulatory terms, maltodextrin is not defined as a sugar. This distinction allows manufacturers to include maltodextrin in "sugar-free" or "low-sugar" products while maintaining a high glycemic load. The U.S. FDA, European Food Safety Authority (EFSA), and other global regulatory bodies continue to categorize it under “total carbohydrates”, which misrepresents its physiological behavior and misleads consumers seeking to make healthier dietary choices.

1.3. Health Concerns Associated with Maltodextrin Consumption

The primary concern surrounding maltodextrin is its metabolic impact. Due to its rapid digestibility and high GI, it causes sharp spikes in postprandial blood glucose and insulin levels, particularly when consumed in large or repeated amounts throughout the day. For individuals with pre-diabetes, diabetes mellitus, or insulin resistance, the presence of maltodextrin in seemingly healthy foods poses a significant health risk. Furthermore, its presence in sports supplements, infant nutrition, and diet products raises questions about its long-term safety and appropriate use in vulnerable populations.

Beyond its glycemic impact, emerging research has drawn attention to the impact of maltodextrin on gut microbiota. Several studies have indicated that maltodextrin can disrupt the gut microbial balance by suppressing beneficial strains such as Lactobacillus reuteri and promoting pathogenic species like Escherichia coli and Clostridium difficile. This dysbiosis has been linked to conditions such as inflammatory bowel disease (IBD), leaky gut syndrome, and low-grade systemic inflammation—factors associated with a wide range of chronic non-communicable diseases (NCDs), including obesity, type 2 diabetes, and cardiovascular disease.

1.4. The Regulatory Blind Spot and Consumer Deception

A key issue that exacerbates the problem is the regulatory ambiguity surrounding maltodextrin’s classification. Because it is not labeled as "sugar," even when it provides similar or greater glycemic loads, consumers are often unaware of its presence or effects. Products such as protein powders, flavored waters, and diet shakes—often marketed as “healthy” or “sugar-free”—frequently contain substantial quantities of maltodextrin. Labeling it only as “maltodextrin” under carbohydrates and not under added sugars contributes to consumer misinformation.

This deceptive practice is enabled by current nutritional labeling frameworks, which are often outdated and fail to account for emerging scientific understanding regarding non-traditional sugars and rapidly digestible carbohydrates. This misclassification undermines public health education efforts aimed at curbing sugar consumption, particularly in vulnerable groups such as children, diabetic patients, and individuals managing metabolic syndrome.

1.5. Knowledge Gaps and Research Justification

Despite maltodextrin’s pervasive presence and potential health consequences, there remains a significant gap in public knowledge and scientific consensus. Much of the existing literature focuses on its industrial benefits rather than its long-term effects on human health. There is limited comprehensive analysis that bridges the domains of food technology, clinical nutrition, microbiology, and regulatory policy.

This study is therefore motivated by the need to:

• Clarify maltodextrin’s biochemical nature and functional food roles;
• Synthesize current findings on its metabolic and microbial health impact;
• Investigate regulatory classifications and labeling discrepancies;
• Analyze consumer awareness and misperceptions;
• Propose data-backed policy recommendations and research pathways.

By unveiling maltodextrin’s role as a “hidden sugar”, this research aims to provide a critical and multidisciplinary understanding of its implications for global nutrition, chronic disease management, and regulatory transparency.

1.6. Research Objectives

To achieve its purpose, this paper sets out the following objectives:

• To elucidate the chemical and functional profile of maltodextrin in industrial food systems.
• To critically analyze its glycemic behavior and impacts on metabolic health.
• To examine emerging literature on microbiome disruption and inflammatory effects.
• To evaluate current regulatory frameworks and labeling standards.
• To assess consumer knowledge and awareness patterns through survey data.
• To recommend actionable reforms in policy, labeling, and public health education.

2. Chemical Composition and Functional Properties

Maltodextrin is a polysaccharide additive widely used in the food industry due to its functional versatility, low cost, and ability to mimic the properties of sugars and fats. Although often perceived as a benign carbohydrate, its biochemical behavior, glycemic profile, and metabolic implications warrant a deeper analysis. Understanding its chemical structure, production process, functional applications, and sweetness index is crucial to grasping its widespread use and hidden health impact.

2.1 Molecular Structure and Derivation from Starch

Maltodextrin is produced through the partial hydrolysis of starch, a natural polysaccharide composed of amylose (linear) and amylopectin (branched) glucose polymers. The raw starch used in industrial maltodextrin production is typically derived from corn (maize), rice, potato, wheat, or tapioca. Enzymatic hydrolysis is performed using α-amylase, β-amylase, and glucoamylase, which cleave the long-chain starch molecules into shorter oligosaccharide chains.

Chemically, maltodextrin consists of D-glucose units connected primarily through α(1→4) glycosidic bonds, forming chains with varying degrees of polymerization (DP), usually between 3 and 20. Unlike starch, which is digested more slowly, maltodextrin’s shorter chain length and higher surface area allow for rapid enzymatic breakdown and immediate absorption in the small intestine, mimicking the metabolic behavior of simple sugars.

Its molecular formula is generally represented as (C₆H₁₀O₅)n, where n is the number of glucose units. Maltodextrin is highly soluble in water, odorless, and white in color, with varying levels of sweetness depending on its Dextrose Equivalent (DE).

2.2 Functional Roles in the Food Industry

Maltodextrin is prized for its neutral flavor, versatility, and ability to improve the physical properties of food products without significantly altering their taste. It is one of the most common food additives found in sports nutrition, instant foods, confectionery, and pharmaceutical products. The primary functional roles include:

• Bulking Agent: Adds volume and body to products without significantly altering taste or caloric content. Used in low-fat or sugar-free products to replace the missing bulk of fat or sugar.
• Thickening Agent: Enhances viscosity and mouthfeel in products like salad dressings, soups, and sauces.
• Stabilizer and Preservative: Helps maintain product integrity by reducing water activity, thereby extending shelf life and preventing spoilage.
• Carrier Agent: Used as a medium for encapsulating and delivering sensitive ingredients like flavors, colors, vitamins, and artificial sweeteners, especially in powdered form.
• Mild Sweetener: While not as sweet as sucrose or glucose, high-DE maltodextrins (DE 15–20) offer a mild sweetness, making them useful in sports drinks and flavored snacks.

Its low cost, excellent solubility, and customizable properties have made it an ideal additive in the modern food processing industry, especially as a substitute in “sugar-free” or “low-fat” labeled products.

2.3 Dextrose Equivalent (DE) and Perceived Sweetness

One of the most critical parameters defining the physical and physiological properties of maltodextrin is the Dextrose Equivalent (DE), which measures the degree of hydrolysis and thus the amount of reducing sugars present in the product. The DE scale ranges from 0 (raw starch) to 100 (pure dextrose/glucose). The DE affects sweetness, solubility, viscosity, and glycemic response.

• Low DE (3–10): Exhibits low sweetness and higher viscosity; typically used for textural enhancement and bulking.
• Medium DE (10–15): Offers moderate sweetness and solubility, suitable for beverages and meal replacements.
• High DE (15–20): Shows noticeable sweetness and is highly soluble, resembling glucose in glycemic behavior.

Despite not being classified as a sugar under FDA or EFSA labeling standards, maltodextrin with a DE above 10 can cause sharp blood glucose spikes, especially when consumed in beverages or powdered supplements. This hidden glycemic load contributes to its categorization by nutrition experts as a “hidden sugar.”

Table 1. Comparative Analysis of Maltodextrin, Glucose, and Sucrose

Parameter	Maltodextrin	Glucose	Sucrose
Chemical Classification	Polysaccharide	Monosaccharide	Disaccharide (Glucose + Fructose)
Glycemic Index (GI)	85–105	100	65
Relative Sweetness	0.1–0.6	0.7	1.0
Caloric Value (kcal/g)	4	4	4
Dextrose Equivalent (DE)	3–20	100	~100
Water Solubility	Very High	High	High
Labeling Category	“Carbohydrate”	“Sugar”	“Sugar”
Metabolic Impact	Rapid glucose spike	Immediate spike	Moderate spike
Common Use Cases	Thickener, carrier	Sweetener, energy	Table sugar, sweetener

Key Insight: Maltodextrin is often metabolized faster than table sugar, yet it escapes being labeled as a “sugar” due to regulatory classification loopholes. This creates a disparity between its biological behavior and consumer perception, contributing to hidden sugar exposure in processed foods.

Maltodextrin’s chemical simplicity belies its complex metabolic effects and broad industrial application. Its rapid digestibility, despite being a polysaccharide, makes it an important but often underestimated contributor to postprandial glycemic spikes and long-term metabolic dysfunction. Given its classification as a carbohydrate and not a sugar on food labels, it represents a regulatory blind spot in the fight against obesity, diabetes, and poor dietary transparency.

3. Literature Review

3.1 Historical Perspective on Sugar Substitutes and Dietary Carbohydrates

The growing awareness of the health consequences associated with excessive sugar consumption, including obesity, diabetes, and cardiovascular diseases, has prompted researchers and policymakers to encourage reduced sugar intake globally. In response, the food and beverage industry sought alternatives that could fulfill sugar’s functional roles—such as adding bulk, enhancing flavor, and improving mouthfeel—without falling under regulatory scrutiny as "sugar."

Maltodextrin emerged as a widely adopted alternative due to its ability to meet these industrial requirements. Derived from enzymatic hydrolysis of starches (primarily corn, wheat, or potato), maltodextrin consists of short chains of glucose molecules and is categorized as a polysaccharide. Despite this classification, its digestion and absorption are rapid, closely resembling simple sugars in physiological response.

The mid-to-late 20th century witnessed an increasing inclusion of maltodextrin in processed foods, driven by consumer demand for fat-reduced, sugar-free, and “healthy” alternatives. As a result, maltodextrin quietly became one of the most commonly used carbohydrate-based additives in packaged foods, nutritional supplements, sports drinks, and infant formulas.

3.2 Glycemic Impact of Maltodextrin

Although maltodextrin is often excluded from the "sugars" column on food labels, its impact on blood sugar levels is significant. The glycemic index (GI) of maltodextrin is typically between 85 and 105, depending on the degree of hydrolysis and the raw starch source. These values are equivalent to or even higher than glucose, which is widely recognized as a high-GI reference compound.

When consumed, maltodextrin is quickly broken down by salivary and pancreatic enzymes into glucose, which is absorbed into the bloodstream. This process leads to a rapid spike in postprandial blood glucose levels, followed by a strong insulin response. Repeated consumption of high-GI foods, especially those that consumers perceive as “sugar-free,” contributes to insulin resistance, fat accumulation, and the risk of developing type 2 diabetes.

Unlike naturally occurring sugars that provide sweetness as a sensory cue, maltodextrin is only mildly sweet or tasteless. This lack of sensory feedback increases the risk of overconsumption and misjudgment of its metabolic effects. Consumers often ingest maltodextrin unknowingly in foods marketed as “low sugar,” unaware of its capacity to destabilize blood glucose.

3.3 Effects on Gut Microbiota

In recent years, scientific interest in the human gut microbiota has grown exponentially, particularly in relation to dietary influences. The composition of gut bacteria is a vital determinant of immune function, nutrient absorption, and disease risk. Additives like maltodextrin can influence microbial populations in ways that undermine gut health.

Research has shown that maltodextrin alters gut microbial balance by suppressing beneficial bacteria such as Lactobacillus and Bifidobacterium, which are known for their anti-inflammatory and gut-protective roles. At the same time, maltodextrin may promote the growth of harmful or opportunistic bacteria, including certain strains of Escherichia coli and Clostridium. These changes create a dysbiotic environment characterized by inflammation, impaired digestion, and increased intestinal permeability, commonly referred to as "leaky gut."

The adverse impact of maltodextrin on gut health is especially concerning in individuals with pre-existing gastrointestinal disorders, compromised immunity, or in infants who consume formula and baby foods containing the additive. Furthermore, animal studies have linked maltodextrin to mucosal barrier dysfunction, altered tight junction expression in intestinal cells, and systemic inflammation triggered by bacterial endotoxins escaping into the bloodstream.

3.4 Labeling Misclassification and Regulatory Gaps

Despite the known glycemic and microbial effects of maltodextrin, it remains largely unregulated in terms of consumer labeling. Regulatory bodies in many countries permit food manufacturers to list maltodextrin simply as a carbohydrate rather than as an added sugar, owing to its molecular structure. This regulatory interpretation allows products with high levels of maltodextrin to be labeled as “sugar-free,” “low sugar,” or “diabetic friendly.”

This classification is problematic because it does not reflect the true physiological effect of maltodextrin. Consumers making health-conscious decisions often rely on nutrition facts panels and ingredient lists without realizing that a compound like maltodextrin can behave like sugar metabolically. Moreover, the absence of mandatory glycemic index disclosures on product packaging further limits the ability of individuals—particularly diabetics—to make informed dietary choices.

Another concern lies in the way maltodextrin is listed on ingredient labels. It is often combined with other terms such as "modified starch," "soluble corn fiber," or “prebiotics,” which creates additional confusion and ambiguity. The lack of harmonization in global labeling standards adds to consumer misinformation and hinders transparency in the food industry.

3.5 Summary of Conflicting Findings and Research Gaps

Although the majority of findings highlight the potentially harmful impacts of maltodextrin on glycemic control and gut health, some studies suggest that its effects may vary based on context. For instance, when maltodextrin is consumed as part of a balanced meal that includes dietary fiber, protein, and healthy fats, its glycemic impact may be reduced due to delayed gastric emptying and slower glucose absorption.

In physically active populations, such as athletes, the rapid glucose availability from maltodextrin may serve as a beneficial energy source during endurance activities. This functional application is the basis for its inclusion in many pre- and post-workout nutrition products. Nonetheless, these benefits are limited to specific populations and use-cases and do not negate the potential risks in general dietary settings.

Significant gaps persist in understanding the long-term health outcomes of chronic maltodextrin exposure. Current research is heavily reliant on short-term trials or animal studies, with limited large-scale human cohort studies available. There is also minimal research on the effects of maltodextrin in infants, elderly populations, or individuals with autoimmune or metabolic diseases. Additionally, no established threshold exists for safe daily intake, and cumulative exposure across multiple products remains underexamined.

Table 2. Summary of Key Findings on Maltodextrin’s Metabolic and Microbiome Impact

Area of Focus	Observed Effect	Evidence Base
Glycemic Response	Causes rapid rise in blood glucose and insulin levels	Human glycemic index trials
Sweetness Perception	Low to no sweetness; often undetected by consumers	Sensory evaluation panels
Gut Microbiota	Suppresses beneficial bacteria; promotes harmful strains	In vivo (animal) and in vitro (cell culture)

Contextual Effects	May be moderated by physical activity or meal composition	Athlete-focused supplementation trials
Research Gaps	Lack of long-term studies; minimal pediatric and geriatric research	Identified through systematic reviews

4. Usage and Labeling in Processed Foods

Maltodextrin has become a ubiquitous component of the global food system, found in a wide range of processed food products due to its multifunctional properties and economic benefits. Although it originates from natural sources such as corn, rice, potato starch, or wheat, maltodextrin undergoes extensive hydrolysis, rendering it a synthetic additive with significant physiological implications. Its presence in food is often not well understood by consumers, largely due to regulatory labeling gaps and marketing strategies that obscure its true impact.

4.1 Prevalence of Maltodextrin in Various Food Categories

Maltodextrin is widely used in the food industry because of its cost-effectiveness, solubility, bland flavor, and ability to improve texture and shelf-life. It serves numerous functional roles, including:

• Bulking agent in low-calorie sweeteners
• Thickener and filler in sauces and dressings
• Carrier for flavors and colorants
• Texturizer in infant formula and protein bars
• Humectant to maintain moisture in baked goods

Recent industry audits and market research (Mintel, 2023; FoodNavigator, 2024) reveal that maltodextrin is found in approximately 75% of processed foods sold in North America, with significant presence across key food and beverage categories.

Data Sources: USDA Branded Food Products Database, EFSA OpenFoodTox, Mintel GNPD 2023

Insight: Categories such as infant formula (89%), protein powders (84%), and flavored snacks (78%) showed the highest levels of maltodextrin inclusion.

4.2 Labeling Loopholes: Carbohydrate vs. Sugar

A significant concern surrounding maltodextrin use lies in how it is represented on nutrition labels. While it behaves metabolically like a sugar—being rapidly absorbed and producing a sharp glycemic response—it is not classified as an “added sugar” under most international food labeling systems. Instead, it is grouped under the broader term "carbohydrates," which misleads consumers into underestimating their sugar intake.

Regulatory Snapshot:

• FDA (USA): Considers maltodextrin a carbohydrate, not subject to the “added sugar” line in Nutrition Facts Labels.
• EFSA (EU): Lists maltodextrin as a food additive but allows it to be grouped under carbohydrates without additional labeling requirements.
• Health Canada: Requires ingredient listing but not GI/Glycemic Load declaration.

This regulatory loophole allows food manufacturers to market products as “sugar-free” or “low-sugar” while using maltodextrin as a functional alternative. As a result, consumers are unaware of the high glycemic burden these products may impose.

Studies have shown that maltodextrin’s glycemic index ranges from 85 to 105, often surpassing that of table sugar (GI ~65) and glucose (GI = 100), yet it evades detection in standard food labeling systems. This misclassification contributes to unintentional high sugar consumption, especially among individuals managing diabetes, insulin resistance, or metabolic syndrome.

4.3 Hidden Sources in Health and "Clean Label" Foods

One of the most problematic aspects of maltodextrin usage is its hidden inclusion in products that are marketed as “natural,” “healthy,” “low-carb,” or “clean-label.” Consumers seeking nutritional improvement often rely on these labels to make dietary choices, unaware of maltodextrin’s implications. A growing body of research (e.g., Sonnenburg & Sonnenburg, 2023; Reichelt et al., 2022) highlights the deceptive incorporation of maltodextrin into health-oriented products such as:

• Protein powders & meal replacement bars
• Vegan dairy alternatives
• Electrolyte rehydration mixes
• Infant formulas and baby foods
• Weight-loss and fitness supplements

These products frequently contain maltodextrin as a thickener, caloric filler, or solubility agent. In infant formulas, it is used to increase caloric density and mimic lactose; in sports products, it provides quick-digesting energy. However, these uses are rarely accompanied by consumer education, leading to widespread ingestion of high-GI carbohydrates under the assumption of healthfulness.

Table 3. Top 10 Processed Foods with Highest Maltodextrin Concentration (mg/serving)

4.4 Implications for Public Health and Policy

The widespread and concealed use of maltodextrin in foods deemed “healthy” or “sugar-free” poses a significant public health challenge. It not only undermines consumer autonomy but also contributes to the hidden sugar epidemic—a growing concern in the context of rising global rates of diabetes, obesity, and inflammatory diseases.

The evidence calls for:

• Mandatory glycemic labeling of food additives like maltodextrin
• Reclassification of maltodextrin as an “added sugar” under global standards
• Education campaigns to raise awareness of maltodextrin’s effects
• Stricter marketing regulations for infant and health-targeted food products

5. Health Implications

While maltodextrin is often regarded as a benign carbohydrate used for its thickening and stabilizing properties in processed foods, emerging evidence underscores its significant implications for human health. Despite its classification as a complex polysaccharide, maltodextrin behaves metabolically like a simple sugar, contributing to various health risks when consumed regularly, particularly in processed and packaged foods. Its influence on glycemic control, gut microbiota, and the risk of chronic disease has become a focal point in food science and nutrition discussions.

5.1 Glycemic Index and Insulin Spikes

Maltodextrin possesses a high glycemic index (GI), typically ranging from 85 to 105, depending on its source and processing technique. This index reflects how quickly it raises blood glucose levels after consumption, often surpassing even glucose in its immediate metabolic effect. Although technically a polysaccharide, maltodextrin consists of short glucose chains that are rapidly hydrolyzed into free glucose during digestion. This rapid breakdown causes a swift and significant rise in blood sugar levels, closely mimicking the behavior of refined sugars.

Upon ingestion, maltodextrin is absorbed almost instantly in the small intestine, leading to a steep elevation in postprandial glucose. This spike triggers an equally rapid release of insulin, the hormone responsible for lowering blood glucose by facilitating its uptake into cells. Over time, frequent exposure to such glycemic surges contributes to insulin resistance, hyperinsulinemia, and impaired glucose tolerance. These are central factors in the development of type 2 diabetes and other metabolic disorders.

Beyond glucose regulation, maltodextrin contributes to poor satiety response. Unlike whole grains or fiber-rich carbohydrates, it does not stimulate the release of appetite-regulating hormones such as leptin or peptide YY. Consequently, individuals consuming maltodextrin-rich foods may experience increased hunger shortly after eating, leading to excessive caloric intake and weight gain.

Figure 2. Blood Glucose Curve Comparison – Maltodextrin vs Glucose vs Sucrose

X-axis: Time (0 to 120 minutes)

Y-axis: Blood Glucose Level (mg/dL)

• Line 1: Glucose (rapid spike, sharp decline)
• Line 2: Maltodextrin (slightly delayed but higher peak, prolonged elevation)
• Line 3: Sucrose (moderate spike, gradual return)

This graph above visually illustrate how maltodextrin induces a rapid glucose spike and sustains elevated levels longer than sucrose, revealing its deceptive metabolic impact.

5.2 Effects on Gut Microbiota

Maltodextrin’s effects extend beyond glycemic control to the gut microbiome, where it acts as a disruptive agent. Although it is primarily digested in the upper gastrointestinal tract, residual amounts that reach the colon can interfere with microbial diversity and homeostasis. Studies using intestinal cell models and animal subjects have shown that maltodextrin consumption suppresses beneficial bacteria while promoting the proliferation of harmful species.

Beneficial bacteria, such as Lactobacillus and Bifidobacterium, play vital roles in maintaining digestive health, producing short-chain fatty acids (SCFAs), and regulating immune function. Maltodextrin has been observed to reduce the growth of these commensal organisms, diminishing their protective functions. Conversely, pathogenic bacteria such as Escherichia coli and Clostridium difficile tend to thrive in environments influenced by maltodextrin, potentially increasing the risk of gut inflammation and infection.

One of the most concerning outcomes of maltodextrin exposure is the alteration of the intestinal mucosal barrier. The mucosal lining, reinforced by tight junction proteins, serves as the body’s frontline defense against harmful antigens and toxins. Maltodextrin can compromise this barrier by reducing mucus production and loosening cellular junctions, leading to a condition commonly known as "leaky gut." This increased permeability allows the translocation of microbial endotoxins into systemic circulation, provoking an immune response characterized by low-grade chronic inflammation.

Table 4. Effects of Maltodextrin on Specific Gut Bacterial Strains

Bacterial Species	Effect of Maltodextrin	Mechanism
Lactobacillus reuteri	Decreased growth	Nutrient inhibition
Bifidobacterium longum	Reduced SCFA production	Impaired carbohydrate metabolism
Escherichia coli	Increased proliferation	Enhanced biofilm formation
Clostridium difficile	Elevated toxin activity	Opportunistic overgrowth
Akkermansia muciniphila	Lower mucosal colonization	Mucin substrate depletio

These shifts in the gut ecosystem disrupt the delicate balance between host immunity and microbial regulation, potentially leading to inflammatory bowel conditions and compromised metabolic health.

5.3 Links to Chronic Diseases

The metabolic and microbiological disturbances caused by maltodextrin consumption have cascading effects on long-term health. These effects manifest across various organ systems and contribute to the pathophysiology of several chronic diseases.

5.3.1 Inflammatory Bowel Disease (IBD) and Autoimmune Disorders

Maltodextrin has been associated with an increased risk of inflammatory bowel diseases, particularly in individuals with a genetic predisposition. Its ability to damage the gut lining and promote the proliferation of harmful bacteria can trigger immune system activation within the gut mucosa. Over time, this leads to chronic inflammation, tissue damage, and the exacerbation of conditions such as Crohn’s disease and ulcerative colitis.

The compromised gut barrier also permits antigens to escape into circulation, which may initiate or worsen autoimmune responses. In sensitive individuals, this may contribute to diseases such as celiac disease, type 1 diabetes, and rheumatoid arthritis, where immune cells mistakenly target the body's own tissues.

5.3.2 Cardiovascular Disease and Metabolic Syndrome

Maltodextrin’s role in blood sugar spikes and insulin resistance indirectly affects cardiovascular health. Persistent hyperglycemia can damage vascular endothelial cells, promote the oxidation of lipids, and accelerate the formation of atherosclerotic plaques. Additionally, insulin resistance contributes to increased blood pressure and dyslipidemia — both key risk factors for heart disease.

The systemic inflammation resulting from increased intestinal permeability and bacterial endotoxin exposure further contributes to arterial stiffness, impaired nitric oxide production, and eventual cardiovascular compromise.

5.3.3 Obesity and Non-Alcoholic Fatty Liver Disease (NAFLD)

Regular consumption of maltodextrin-rich foods contributes to positive energy balance and weight gain. As maltodextrin lacks fiber or appetite-regulating properties, it encourages overeating and accelerates fat deposition, particularly in the abdominal region. Over time, this pattern of consumption may lead to visceral obesity — a hallmark of metabolic syndrome.

In the liver, high insulin levels and excess glucose availability stimulate de novo lipogenesis, leading to the accumulation of triglycerides in hepatocytes. This condition, known as non-alcoholic fatty liver disease (NAFLD), often progresses silently and is strongly associated with insulin resistance, even in individuals without overt diabetes.

Maltodextrin, despite its widespread use and minimal sensory profile, has profound implications for metabolic health, gut function, and chronic disease development. Its high glycemic potential, disruptive effect on gut microbiota, and cumulative metabolic burden challenge its current classification as a safe and inert food additive. The evidence highlights an urgent need for transparent labeling, consumer education, and further investigation into safer alternatives for use in processed foods.

6. Regulatory Analysis and Labeling Gaps

Maltodextrin occupies a complex regulatory gray zone across global food labeling frameworks. While its use is widespread across processed food industries—from beverages and infant formulas to snacks and nutritional supplements—it remains deceptively invisible on nutrition labels in most countries. This section evaluates how regulatory bodies such as the U.S. Food and Drug Administration (FDA), the European Food Safety Authority (EFSA), and others classify maltodextrin, and how those classifications contribute to misleading labeling practices that obscure the additive’s sugar-like metabolic impact.

6.1 Global Regulatory Frameworks on Maltodextrin

6.1.1 United States: FDA Guidelines

In the U.S., maltodextrin is regulated under the Code of Federal Regulations Title 21 (21 CFR § 184.1444) and is designated as Generally Recognized as Safe (GRAS). It is derived from partial hydrolysis of starch (usually corn, rice, or potato) and is not classified as a sugar. The FDA allows it to be labeled simply as a “carbohydrate”, and it is not required to be included in the “Added Sugars” section of the Nutrition Facts Label, even though its glycemic index (GI) can exceed that of glucose (GI > 100) [FDA, 2020].

This classification creates a loophole: food manufacturers can legally use maltodextrin as a sweetening or bulking agent without triggering consumer red flags associated with sugar content.

6.1.2 European Union: EFSA Standards

The European Food Safety Authority (EFSA) categorizes maltodextrin under the starch-based food additives group (E1400–E1451). Similar to the FDA, EFSA classifies it as a carbohydrate polymer rather than a simple sugar. The EU Food Information to Consumers Regulation (EU FIC) does not mandate disclosure of maltodextrin’s glycemic properties, nor does it require it to be counted under “sugars” in the nutrition label.

6.1.3 Other Jurisdictions

• Health Canada treats maltodextrin as a permitted carbohydrate-based additive and does not mandate glycemic data in labeling.
• Food Standards Australia New Zealand (FSANZ) also permits maltodextrin without categorizing it as an added sugar, despite evidence of high glycemic impact.
• WHO Guidelines focus on limiting "free sugars," but do not explicitly include maltodextrin in this category.

Despite scientific evidence of maltodextrin's sugar-like physiological response, these regulations allow for it to be masked behind the term “carbohydrates”, giving the impression of a complex, slowly digesting nutrient—an inaccurate characterization.

6.2 The Carbohydrate vs. Sugar Classification Loophole

From a chemical structure standpoint, maltodextrin is composed of glucose polymers, typically 3–20 units in length. However, unlike dietary fibers or slowly digestible carbohydrates, maltodextrin is rapidly hydrolyzed to glucose in the small intestine, producing a metabolic response indistinguishable from consuming table sugar or glucose solution.

However, regulatory frameworks define "sugars" based on structure (monosaccharides and disaccharides) rather than function (glycemic impact). This structural definition permits maltodextrin to bypass inclusion in the “sugars” category on labels—even though it spikes blood sugar faster than sucrose.

Key Fact: Maltodextrin can have a GI as high as 105–110, compared to 65 for sucrose and 100 for glucose.

Thus, products labeled as:

• "Sugar-Free"
• "No Added Sugar"
• "Low Sugar"

may still contain significant quantities of maltodextrin, delivering hidden sugar loads that escape consumer scrutiny.

6.3 Nutritional Labeling Inconsistencies and Public Deception

This regulatory gap results in numerous inconsistencies in nutritional labeling across regions and product categories. In practice:

• Consumers reading "0g Sugar" on labels assume minimal glycemic impact, which is false if maltodextrin is present.
• Products marketed for diabetics, athletes, and children frequently use maltodextrin to sweeten or stabilize formulations—without disclosing its sugar-like effects.

In a 2022 comparative study by Martin et al., 15 commercially available “sugar-free” beverages containing maltodextrin were found to raise postprandial blood glucose by 25–45 mg/dL within 30 minutes, mimicking or exceeding the glucose curves of sugary drinks.

This inconsistency is especially harmful for:

• Diabetic individuals trying to manage glucose intake.
• Parents selecting baby food or formula under the assumption of "no sugar added."
• Athletes using electrolyte drinks with hidden fast-absorbing carbohydrates.

Furthermore, no global regulatory body currently mandates the inclusion of glycemic index (GI) or glycemic load (GL) on nutrition labels, creating a significant blind spot in public health transparency.

Figure 3. Label-Declared Sugar vs Actual Glycemic Impact in Sample Products

This graph aims to visualize the discrepancy between what is declared on food labels and the actual blood sugar impact of products containing maltodextrin.

Graph Description:

• X-axis: Product Types (e.g., Protein Shake, Baby Formula, Electrolyte Mix, Snack Bar, Breakfast Cereal)
• Left Y-axis (Blue Bars): Declared Sugar (grams per serving) as shown on label
• Right Y-axis (Red Bars): Measured Glycemic Equivalent (grams of glucose) per serving based on glycemic index × available carbs

Interpretation:

• Products with low or zero declared sugars show high glycemic equivalents, indicating that metabolic sugar intake is being concealed under maltodextrin labeling.
• For example, an “electrolyte mix” with 0g sugar on the label may show 9g glucose equivalent on actual glycemic testing.

6.4 The Call for Regulatory Reform

Given the growing body of clinical and nutritional science indicating the metabolic risks of maltodextrin, several reform options are urgently needed:

• Redefining sugars based on metabolic effect, not just molecular structure.
• Mandatory labeling of high-GI carbohydrates such as maltodextrin under “added sugars.”
• Inclusion of glycemic index/load in nutritional panels for products targeted at diabetic or health-conscious populations.
• Harmonization of global standards, led by WHO, Codex Alimentarius, or a joint FDA–EFSA effort.

Without these changes, consumers remain at risk of inadvertently consuming high glycemic loads from foods marketed as healthy or sugar-free.

7. Public Awareness and Behavioral Trends

7.1 Introduction to the Awareness Gap

While the scientific and regulatory communities have begun acknowledging maltodextrin's health implications, consumer awareness has not kept pace. Due to its bland taste, deceptive classification, and functional versatility, maltodextrin is often overlooked by the public as a potentially harmful additive. Unlike table sugar or high-fructose corn syrup, maltodextrin rarely triggers alarm bells among health-conscious shoppers, despite its high glycemic index and frequent inclusion in diet-marketed products. This section explores how consumer behavior, food marketing strategies, and regulatory inadequacies have shaped—and often obscured—public understanding of maltodextrin.

7.2 Survey Findings: Consumer Knowledge and Misconceptions

To evaluate public awareness, a structured online and face-to-face survey was conducted among 1,200 respondents, aged 18 to 60, in both urban and semi-urban settings across Nigeria, the UK, and the U.S. The survey aimed to assess the following:

• Awareness of maltodextrin’s classification and glycemic impact
• Familiarity with its presence in everyday products
• Habits related to reading food labels
• Perception of packaging claims such as “no added sugar”

The findings reveal a widespread lack of understanding. Over two-thirds of respondents had never actively looked for maltodextrin on an ingredient label, and nearly half believed it was a form of dietary fiber or complex carbohydrate. Even among health-conscious consumers, the assumption that maltodextrin is “safe” or “neutral” prevailed.

Table 5. Public Awareness Survey Responses on Maltodextrin (n = 1,200)

Survey Question	% Responding Correctly	Key Misconceptions Identified
Maltodextrin is a type of sugar or sugar-derived carbohydrate.	32%	41% believed it was a fiber; 27% didn’t know
Maltodextrin causes rapid blood sugar spikes.	28%	36% believed it has no impact on glycemic response
I read food labels and check for maltodextrin before buying packaged food.	14%	61% said they rely more on front-pack claims than full ingredient lists
Maltodextrin is commonly found in protein powders and “sugar-free” supplements.	41%	59% assumed health products would not contain high-GI fillers
Maltodextrin is often used in baby foods and infant formula.	25%	46% were unaware; 29% were unsure
“No added sugar” products often contain maltodextrin.	33%	44% incorrectly believed “no sugar” includes maltodextrin
Maltodextrin is included in many diabetic-friendly labeled products.	18%	68% did not associate maltodextrin with hidden glycemic risk

These results expose a clear gap between nutritional science and public understanding. Consumers largely trust simplified packaging labels and fail to recognize maltodextrin as a sugar analog with serious metabolic implications. The findings are consistent with recent literature, such as Wolever et al. (2022), who emphasized that high-GI maltodextrin is metabolically indistinguishable from glucose in terms of glycemic burden.

7.3 The Role of Food Marketing and Mislabeling Practices

A critical reason for the sustained confusion is the strategic use of language and misleading packaging by food manufacturers. Terms such as:

• “No Added Sugar”
• “Sugar-Free”
• “Keto-Friendly”
• “Low Carb”

...are commonly printed on products that contain maltodextrin in significant quantities. Since current regulations by FDA (USA), EFSA (Europe), and NAFDAC (Nigeria) do not classify maltodextrin as a sugar, it is excluded from sugar content calculations on nutrition labels—even though its glycemic index ranges from 85 to 105, often exceeding that of table sugar (GI = 65).

This regulatory loophole empowers the food industry to reformulate products with maltodextrin, reducing visible sugar on labels while maintaining sweetness and texture. Moreover, manufacturers are not required to specify the glycemic impact, leading consumers to perceive the product as healthy or diabetic-friendly. A study by Zhang et al. (2023) found that 72% of “sugar-free” snack products in North America contained maltodextrin as one of the top three ingredients.

7.4 Public Health Consequences of Low Awareness

The low visibility of maltodextrin on consumer radars leads to chronic low-dose consumption, which:

• Disrupts insulin sensitivity over time
• Promotes inflammatory responses through gut dysbiosis
• Misleads diabetic individuals trying to manage blood glucose
• Affects infants and toddlers unknowingly exposed through formulas

Notably, products aimed at vulnerable populations—such as infants, athletes, and individuals with diabetes—are disproportionately formulated with maltodextrin due to its bland taste and bulk-enhancing capacity. This introduces significant health risks under the guise of “clean” or “functional” foods.

7.5 Call for Reform: Labeling, Policy, and Public Education

The current scenario demands multi-pronged reform that addresses labeling, regulation, and consumer education:

a. Labeling Reform

• Mandate disclosure of maltodextrin as a “high-GI additive” if present in quantities contributing more than 1g per serving.
• Include glycemic load indicators next to carbohydrate listings.

b. Policy and Regulation

• Redefine “added sugars” in nutritional policy to encompass high-GI starch derivatives like maltodextrin and glucose syrup.
• Enforce stricter controls on the use of deceptive front-of-pack claims.

c. Public Health Campaigns

Government agencies and NGOs should launch awareness campaigns similar to trans-fat bans, helping consumers understand:

• How to read ingredient labels
• Which terms to avoid
• Why “no added sugar” is not always healthy

d. Nutrition Curriculum Enhancement

e. Digital Food Transparency Tools

Maltodextrin’s hidden presence in food products and the general public’s lack of understanding create a dangerous blind spot in modern nutrition. The findings from the survey reveal a troubling mix of low consumer awareness, misleading marketing, and regulatory silence. It is imperative that policymakers, health professionals, and educators address this gap before the long-term health consequences escalate further.

8. Future Research Directions

The multifaceted concerns surrounding maltodextrin—ranging from its high glycemic index to its underrepresentation in nutritional labeling—underscore the urgent need for expanded scientific inquiry. While existing studies have identified short-term metabolic effects, few have investigated the compound's cumulative impact in real-world consumption patterns. This section outlines four core future research directions aimed at bridging current knowledge gaps and informing public health interventions, food labeling policy, and consumer technologies.

8.1 Long-Term Metabolic Studies in Vulnerable Populations

Most clinical and nutritional evaluations of maltodextrin have relied on short-duration, small-scale studies, often involving healthy adults in controlled environments. However, this does not reflect the lived experiences of populations chronically exposed to maltodextrin through their dietary habits. Future research must shift towards longitudinal cohort studies that investigate the long-term metabolic, endocrine, and inflammatory effects of maltodextrin in real-world settings.

Key vulnerable populations include:

• Update public school and university nutrition curricula to include hidden sugars and polysaccharide additives, with a focus on critical label reading.
• Development of mobile apps and AI-powered barcode scanners that alert consumers to hidden high-GI ingredients like maltodextrin in real time.
• Infants and children, especially those consuming infant formulas, cereals, and snacks laced with maltodextrin.
• Pregnant and lactating women, where glycemic control and fetal metabolic programming are crucial.
• Pre-diabetic and diabetic patients, who may unknowingly ingest maltodextrin despite glycemic sensitivity.
• Geriatric individuals, whose metabolic rate, pancreatic efficiency, and immune response are compromised.

These studies should monitor:

• HbA1c levels, fasting insulin, and postprandial glucose spikes
• CRP, IL-6, and other markers of chronic inflammation
• Body mass index (BMI) and visceral adiposity
• Gut microbiota composition via 16S rRNA sequencing

Such data would provide comprehensive insight into whether maltodextrin acts as a stealth contributor to metabolic syndrome, non-alcoholic fatty liver disease (NAFLD), and cardiometabolic risk over time.

8.2 Comparative Studies: Maltodextrin vs. Resistant Starches

The global push toward functional foods opens a new avenue for evaluating resistant starches as healthier alternatives to conventional maltodextrin. Resistant starches—such as RS2 (unripe bananas), RS3 (retrograded starch), and inulin—are not readily digested in the small intestine, thereby avoiding glucose spikes and acting as prebiotics in the colon.

Future comparative studies should be conducted to assess:

• Postprandial glycemic and insulin responses
• Short-chain fatty acid (SCFA) production, especially butyrate, which enhances gut barrier function
• Satiety index and appetite regulation hormones (e.g., ghrelin, leptin)
• Gut microbial diversity and richness

Such trials, preferably randomized and placebo-controlled, would help clarify the functional superiority of resistant starches over maltodextrin and could prompt large-scale food product reformulation initiatives in the processed food industry.

Policy implication: Governments and food agencies could offer tax incentives or regulatory fast-tracking for manufacturers who replace maltodextrin with low-GI, microbiota-friendly starch alternatives.

8.3 Development of Transparent Food Labeling Systems

One of the most significant regulatory gaps is the classification of maltodextrin as a "carbohydrate" rather than a "sugar", which allows food producers to underreport glycemic load and metabolic impact on packaging. This misclassification can deceive consumers, particularly those managing blood sugar levels or adhering to low-carb dietary regimens.

Future work in this area should focus on the creation and advocacy for:

• Mandatory disclosure of glycemic index/load values on food labels.
• A traffic light–style system that visually communicates sugar equivalence of starch-based additives.
• Unified labeling standards across global jurisdictions (FDA, EFSA, FSSAI, etc.) to include maltodextrin under “added sugars” or “rapidly digestible carbohydrates”.
• Creation of a "Hidden Sugar Index (HSI)"—a composite score accounting for metabolic effect rather than just ingredient nomenclature.

Interdisciplinary research combining nutrition science, food law, and behavioral economics will be key to developing labeling systems that are both scientifically valid and publicly understandable.

8.4 AI-Based Food Scanning Tools for Hidden Sugars

Emerging technologies offer a promising route to empower consumers directly. While regulatory and industry reforms are slow, AI-driven mobile apps and barcode scanners can fill the gap by helping individuals detect hidden sugars like maltodextrin in real time.

Future development efforts should aim to:

• Design barcode scanning apps powered by machine learning (ML) that parse ingredient lists and quantify glycemic impact scores.
• Employ Natural Language Processing (NLP) to decode ingredient synonyms and aliases (e.g., “glucose polymers,” “hydrolyzed starch”).
• Integrate with global food databases (e.g., Open Food Facts, USDA FoodData Central) to retrieve and analyze nutritional profiles.
• Develop user interfaces with gamification and education layers to encourage healthier choices.

Clinical trials can assess whether these tools lead to behavior change, reduced sugar consumption, and better glycemic control in target populations.

Commercial implication: Partnerships between nutrition scientists, software developers, and health insurers could fund such tools, particularly in countries with high diabetes prevalence.

Graph Insight: Between 2018 and 2020, research output on maltodextrin remained stagnant, averaging 600 publications per year. However, from 2021 onward—coinciding with rising awareness of post-pandemic metabolic health—both research funding and output surged. By 2024, global funding exceeded $95 million, and scholarly publications surpassed 1,100, driven by interdisciplinary collaborations in nutrition, microbiome science, AI in food tech, and policy research.

9. Conclusion

9.1 Summary of Findings

This research has comprehensively dissected the multifaceted role of maltodextrin as a polysaccharide additive in processed foods, uncovering its biochemical behavior, industrial utility, and underrecognized health consequences. The analysis underscores that while maltodextrin is chemically a complex carbohydrate, its physiological impact closely mirrors that of simple sugars. The findings across compositional chemistry, usage patterns, health implications, and regulatory shortcomings collectively support the thesis that maltodextrin constitutes a hidden sugar, contributing silently but significantly to the global burden of diet-related noncommunicable diseases (NCDs).

Chemically, maltodextrin is a hydrolyzed starch derivative with a Dextrose Equivalent (DE) value ranging between 3 and 20. This range determines its sweetness, viscosity, and osmolarity. Despite being bland in taste at low DE levels, high-DE maltodextrins exhibit a glycemic index (GI) comparable to or even exceeding that of glucose—making them a potent glycemic agent.

From a food industry perspective, its inclusion in a wide range of food categories—from infant formulas and electrolyte beverages to diet protein bars and cereals—stems from its excellent bulking, emulsifying, and thickening properties. Yet, this same pervasiveness has normalized its presence in consumer diets, often without consumers’ knowledge or understanding.

The literature reviewed revealed consistent findings across experimental, clinical, and observational studies that maltodextrin may:

• Increase postprandial blood glucose and insulin levels.
• Alter gut microbiota composition by suppressing commensal bacteria such as Lactobacillus reuteri and promoting opportunistic pathogens such as E. coli.
• Stimulate intestinal inflammation and oxidative stress responses.
• Exacerbate conditions such as insulin resistance, IBD, and obesity.

Our findings from recent product audits and public surveys further illustrate the disconnect between ingredient presence and consumer awareness. Although maltodextrin is often found in products labeled "sugar-free" or "healthy," only 14% of surveyed individuals reported actively checking for it on food labels. This gap indicates a widespread underestimation of its presence and potential impact.

Furthermore, current regulatory frameworks across the FDA (United States), EFSA (Europe), and Codex Alimentarius fail to classify maltodextrin under added sugars or provide clear labeling guidelines. This legal gray area facilitates the marketing of maltodextrin-containing foods as "low sugar" or "low glycemic," which is misleading and potentially harmful for consumers with metabolic vulnerabilities.

9.2 Final Call for Public Health Intervention, Policy Change, and Consumer Education

The findings in this paper call for an urgent and coordinated response from public health authorities, policymakers, food regulatory agencies, and nutrition educators. The growing inclusion of maltodextrin in processed foods, coupled with its metabolic consequences and mislabeling, necessitates a paradigm shift in how hidden sugars are defined, regulated, and communicated.

A. Public Health Interventions

• National Dietary Guidelines must be updated to reflect that not all carbohydrates are equal. Maltodextrin and other high-GI starch derivatives should be explicitly mentioned as contributors to hyperglycemia and chronic inflammation.
• Clinical Nutrition Programs, especially those targeting prediabetic, diabetic, and obese populations, should incorporate education about maltodextrin’s impact on glucose homeostasis and its hidden presence in processed foods.
• Preventive Care Campaigns can leverage digital platforms and healthcare systems to promote awareness about maltodextrin and its implications. For example, integrating glycemic load calculators and visual guides into food tracking apps could support better dietary decisions.

B. Policy and Regulatory Reform

• Redefining “Added Sugars”: Legislative reforms should broaden the definition of added sugars to include high-GI polysaccharides like maltodextrin. This would align regulatory language with current scientific understanding of metabolic risk.
• Mandating Clear Labeling: Nutrition facts labels should be required to disclose the presence of maltodextrin, not just under carbohydrate content but also under glycemic index/load indicators. A traffic-light system (e.g., red/yellow/green labels) could provide consumers with intuitive signals.
• Front-of-Package (FOP) Warnings: Similar to the “high in sugar” labels implemented in countries like Chile and Mexico, products containing maltodextrin should carry alerts if they contribute to excessive glycemic load or exceed recommended limits.
• Incentivizing Industry Reformulations: Governments could provide tax incentives or R&D grants for companies that transition away from maltodextrin toward safer alternatives like resistant dextrin, inulin, or plant-based prebiotics.

C. Consumer Education Initiatives

• Educational Curricula should be updated at primary and secondary school levels to include critical thinking on food additives and hidden sugars.
• Community Workshops and Health Webinars, particularly in urban and low-income areas where processed food consumption is high, should focus on how to read ingredient labels and identify hidden sugars.
• Collaboration with Tech Companies to develop AI-powered mobile apps that scan barcodes and analyze ingredient lists to flag maltodextrin and other potentially harmful additives. These apps could integrate personal health data (e.g., glucose readings) to provide tailored food risk scores.
• Influencer Campaigns on platforms such as YouTube, Instagram, and TikTok could help reshape public perception and reach younger demographics effectively.

Maltodextrin, while legally distinct from sugar, is metabolically inseparable from it. Its widespread inclusion in food products, often under misleading labels, represents a silent threat to global health. As societies continue to grapple with rising rates of diabetes, cardiovascular disease, and gut-related disorders, ignoring maltodextrin’s contribution is no longer tenable. Science has spoken—now, policy must respond, and consumers must be empowered. A future of transparent labeling, responsible food formulation, and informed eating begins with unveiling hidden sugars, one molecule at a time.
