Fiber From Corn Starch May Help Increase Feelings of Fullness

Resistant dextrin is a type of water-soluble dietary fiber made from natural corn starch. A new study has found that supplementation with resistant dextrin may help increase feelings of fullness and support blood sugar.

Participants in the study included 20 normal weight and 16 overweight adults. They consumed 14 grams of resistant dextrin in a beverage at mid-morning and mid-afternoon or a placebo daily for 28 days. They switched interventions after a 28-day washout period.

The researchers evaluated feelings of fullness and blood sugar response after consuming the mid-morning drink on days 1, 14, and 28. They also measured blood pressure.

Supplementation with resistant dextrin was associated with greater feelings of fullness on days 14 and 28. It was also associated with a reduction in blood sugar response to the beverage. In addition, normal weight participants saw a decrease in systolic blood pressure on day 14.

The study was conducted by researchers from the University of Reading. It was published online ahead of print on June 25, 2021, in the European Journal of Nutrition.
