Wheat

Studies in people

• Open question

  Easing gut symptoms²

  Removing certain wheat parts or following a low-FODMAP diet may ease gut symptoms in people sensitive to gluten.

• Concern

  Digestive reactions to food³

  Wheat products are known or suggested to cause adverse reactions in humans, including coeliac disease and allergies.

• Concern

  Oral desensitization risks⁴

  In people, wheat oral immunotherapy often helps desensitize, but it can also cause allergic reactions, sometimes severe.

• Open question

  Pasta nutrition⁶

  Adding moringa leaf powder to wheat pasta boosted its minerals and antioxidants, and taste testers still liked it.

Animal and lab studies only

• Open question

  Blood sugar response¹⁰

  In lab studies, wheat ground into smaller pieces released more starch and glucose than larger pieces.

• Benefit

  Weight, blood sugar and liver health¹¹

  In animal studies, wheat bran reduced weight gain, blood sugar and liver fat, with coarser bran working better than ultra-fine.

Study type not stated

• Concern

  Gluten-related gut issues⁷

  People with celiac disease or wheat allergy must avoid wheat, but scientists still debate other gluten-linked gut problems.

• Concern

  Gut bacteria changes⁸

  Eating wheat proteins can trigger gut problems in some people, and avoiding them changes the mix of gut bacteria.

• Concern

  Gut reaction causes⁹

  Wheat can trigger celiac disease, wheat allergy and non-celiac wheat sensitivity, but scientists do not yet know what causes the last one.

How it’s made and used

• Gluten-free diet adherence⁵

  People with self-reported wheat sensitivity often stop following a gluten-free diet over time.

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.
