What it is

Maltodextrin is a highly processed starch-derived carbohydrate used as a thickener, filler, and preservative in processed foods. It has a high glycemic index (85-105, compared to table sugar at 65) and is rapidly absorbed, causing blood sugar spikes.

WATCH

While not toxic, maltodextrin's high glycemic index makes it a contributor to blood sugar instability, particularly concerning in products marketed to children. It is often used as a cheap filler with no nutritional benefit. More concerning in liquid form (beverages) due to even more rapid absorption.

Why it matters

Very high glycemic index (85-105): causes rapid blood sugar spikes
No nutritional value: used purely as filler and processing aid
May affect gut bacteria composition and promote E. coli adhesion
More concerning in beverages due to rapid liquid absorption

The research

Maltodextrin, Modern Starvation, and TNF-alpha-Mediated Death of Intestinal Epithelial Cells

Arnold AR, et al. Nutrition Reviews, 2018. Various studies reviewed by consumer health organizations

"Research suggests maltodextrin may impair gut barrier function and promote inflammatory conditions in the intestinal epithelium"

Who should care most

Children with blood sugar regulation concerns. Children with inflammatory bowel conditions. General concern for all children due to high glycemic impact.
