Dextrin

Studies in people

• Benefit

  Blood sugar control²

  In people, resistant dextrin helped lower fasting blood sugar and improved insulin resistance, though longer studies are still needed.

• Open question

  Gut gas and digestion³

  In people, resistant dextrin caused gas to rise at first, then fall, and changed gut bacteria.

Animal and lab studies only

• Benefit

  Gut bacteria gas production⁵

  In lab studies, resistant dextrin mixed with inulin fed gut bacteria from older people and made less gas than inulin alone.

• Benefit

  Gut bacteria and digestion⁶

  In lab studies, dextrin fed good gut bacteria and boosted helpful acids they make.

• No harm found

  How the body handles it⁷

  In animal studies, dextrin was broken down into sugars the body normally digests, with no lasting problems seen.

Study type not stated

• Benefit

  Digestive system and heart health⁴

  Wheat dextrin is a soluble fiber that may help digestion, blood sugar, and cholesterol, but scientists still debate these benefits.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted.
