Hidden Carb Maltodextrin Harms Gut Health, Spikes Blood Sugar
Many foods labeled “sugar-free” may still contain an ingredient called maltodextrin, which can negatively impact your health. This common food additive, found in about 60% of processed foods, acts more like sugar than sugar itself, leading to rapid blood sugar spikes and potentially harming your gut microbiome.
What is Maltodextrin?
Maltodextrin is derived from starches like corn, potato, or rice. Through a chemical process involving acids and enzymes, these starches are broken down into smaller units. While it’s not classified as sugar because it has more than two sugar units, it quickly converts to sugar in your body. For comparison, an apple has a glycemic index of 36, and table sugar is 65. Maltodextrin, however, can have a glycemic index ranging from 136 to 180, indicating a much faster and higher spike in blood sugar levels.
Related Ingredients to Watch For
Maltodextrin is not the only ingredient with similar effects. Other terms to look out for on food labels include:
- Corn Syrup Solids: Essentially smaller pieces of maltodextrin.
- Modified Food Starch: Starches chemically altered to change their properties. The term “modified” often means it has been broken down using chemicals.
- Modified Cornstarch and Tapioca Starch: Similar to modified food starch, these are processed starches.
These ingredients can create a similar negative impact on your body as maltodextrin.
The Gut Health Connection
Beyond blood sugar spikes, maltodextrin can cause significant damage to your gut lining. Research, including studies from the Cleveland Clinic on animals, has shown that maltodextrin can reduce the protective mucus layer in your intestines. This thinning of the gut wall allows bacteria to move closer to the intestinal lining, a condition known as microbial encroachment.
Furthermore, maltodextrin can promote the growth of certain bacteria, like E. coli, which has been linked to inflammatory bowel diseases such as Crohn’s disease. It can also encourage bacteria to develop structures called pili, which help them attach to the gut wall and form protective colonies that can evade the immune system. Some research even suggests maltodextrin supports the colonization of Salmonella.
These effects can contribute to gut inflammation and other digestive issues, even when consumed in small amounts regularly. Despite its potential harm, maltodextrin is often classified as “Generally Recognized As Safe” (GRAS) by regulatory bodies, a designation that may allow the food industry to use it without extensive independent safety testing.
Impact on Vitamin B1 Levels
Consuming sugars and refined carbohydrates like maltodextrin can significantly deplete your body’s reserves of Vitamin B1, also known as thiamine. Your body stores only a small amount of B1, and its consumption is necessary for energy production. When B1 levels are low, your body’s energy production falters, which can lead to fatigue, decreased stress tolerance, and even restless legs at night.
In the medical field, paramedics sometimes administer a high dose of B1 to malnourished patients before giving them glucose. This highlights the critical role of B1 in energy metabolism. Many individuals with diabetes may suffer from B1 deficiency, which can manifest as peripheral neuropathy—nerve damage that often affects the feet and toes. Supplementing with higher doses of B1, particularly a fat-soluble form like benfotiamine, may help heal this nerve damage.
A lack of B1 can also affect heart function, breathing, blood pressure, and contribute to anxiety and gut problems. Symptoms like persistent anxiety or a feeling of air hunger can be indicators of a B1 deficiency.
Resistant Maltodextrin: A Closer Look
Resistant maltodextrin is a processed form of maltodextrin designed to resist breakdown in the body and supposedly not spike blood sugar. It’s often marketed under brand names like Fibersol 2 and classified as a fiber by the FDA. However, concerns remain about its long-term effects, especially when consumed alongside other ingredients. Most studies showing its benefits have been funded by the companies that produce it, raising questions about potential bias and the lack of independent research.
How to Identify and Avoid Maltodextrin
The most effective way to avoid maltodextrin and similar ingredients is to read food labels carefully. Look for maltodextrin, modified food starch, corn syrup solids, and modified cornstarch in the ingredient list, especially in products marketed as “sugar-free” or “low-carb.” It can be found in a wide range of items, including sugar-free drink mixes, protein powders, protein bars, electrolyte powders, salad dressings, instant soups, and seasoning packets.
