Is Maltodextrin Safe for Diabetics Even Though It Is High on the Glycemic Index?

Maltodextrin is safe for diabetics even though it is high on the glycemic index, but it is a carbohydrate that affects blood sugar, states Healthline. Manufacturers treat the starch with enzymes, acid or heat to make resistant maltodextrin, an isolated fiber, which may lower blood sugar.

Diabetics need to be aware when consuming foods containing maltodextrin, according to Healthline. Maltodextrin is a highly processed substance that the U.S. Food and Drug Administration has approved for food use. It is often used as an inexpensive filler or thickener in foods such as canned fruits and bottled dressings. Manufacturers make maltodextrin from rice, corn or potato starch and sometimes wheat. They cook the starches and add enzymes or acids to continue the chemical breakdown process, which produces a white powder.
