Maltodextrin Side Effects: Hidden Dangers in Everyday Foods

What Is Maltodextrin? Understanding This Common Additive

Maltodextrin is a highly processed carbohydrate derived from starches such as corn, wheat, rice, or potato. Frequently found in processed foods, maltodextrin serves as a thickener, filler, and preservative in products like sauces, salad dressings, crisps, yoghurts, and nutrition bars. Surprisingly, even some foods marketed as “healthy”—including certain bone broths—contain maltodextrin.

Why Is Maltodextrin a Health Concern?

Despite its widespread use, maltodextrin poses several health risks. This additive has no nutritional value and does not offer any essential health benefits. The primary concerns come from its side effects, which are particularly troubling for individuals focused on gut health.

Common Maltodextrin Side Effects

• Bloating and digestive discomfort
• Stomach cramps and gas
• Diarrhea and noisy digestion
• Skin irritations
• Unexplained weight gain
• Difficulty breathing (especially in those with asthma)
• Spiking blood sugar and blood pressure due to its high glycemic index

Maltodextrin, Gut Health, and Allergies

Ironically, products designed to promote gut healing, such as bone broth, can occasionally include maltodextrin—an ingredient that can trigger gut disturbances. In addition, maltodextrin is often sourced from genetically modified corn, potentially introducing GMOs and pesticides into your diet. It may also suppress beneficial antibiotics and disrupt healthy gut bacteria, further impacting digestive health.

When Is Maltodextrin Ever Beneficial?

The only scenario where maltodextrin may provide use is for rapid energy replenishment in sports nutrition. Its high glycemic index allows for quick absorption and energy delivery to muscles after intense exercise. Nevertheless, this potential benefit does not outweigh the possible negatives for most people’s everyday diets.

How to Avoid Maltodextrin in Your Diet

Maltodextrin can be hard to spot since it is present in many everyday food products. The best approach is to:

• Focus on whole, natural foods

• Check ingredient labels for “maltodextrin”

• Avoid highly processed, packaged goods whenever possible 

Being mindful about the ingredients in food is key to maintaining good overall health and optimal gut function.

Maltodextrin is a hidden additive in many processed foods, with several potential side effects that can negatively impact digestive health, blood sugar control, and overall wellbeing. By becoming more aware and making smarter food choices, it is possible to reduce exposure to maltodextrin and support a healthier lifestyle.
