Wheat protein

Studies in people

• Benefit

  Muscle building in older men⁵

  In older men, eating 35g of wheat protein built muscle less than casein, but 60g of wheat protein did build muscle.

• Benefit

  Muscle building after eating⁶

  In young men, eating 30 g of wheat protein boosted muscle building just as much as milk protein.

• Benefit

  Heart health and blood fats⁸

  Wheat protein in bread lowered blood triglycerides in people with high cholesterol, but wheat bran did not change cholesterol.

Animal and lab studies only

• Benefit

  Blood sugar and antioxidant effects¹²

  In lab studies, wheat protein peptides broke down differently during digestion, and some smaller pieces blocked a blood sugar enzyme better afterward.

• Concern

  Coeliac immune reaction¹³

  Purified wheat protein fractions like alpha gliadin triggered an immune response only in cells from coeliac patients.

Study type not stated

• Open question

  Oil in fried food¹⁰

  Wheat protein helps form a gluten network that may cut how much oil fried wheat foods soak up.

Allergies and intolerances

These are about people with an allergy, an intolerance or coeliac disease. The signal is about the ingredient itself, and these are about the person eating it, so the signal does not count them.

• Exercise-triggered allergic reaction²

  In some people, wheat protein triggers a severe allergic reaction when they exercise after eating it.

• Allergen risk in hydrolysates⁴

  Wheat protein enzymatic hydrolysates could still trigger allergic reactions in people allergic to wheat.

• Digestion-resistant allergens⁹

  Wheat protein allergies can look different in different people, and some wheat proteins survive stomach digestion.

How it’s made and used

• Allergy test accuracy³

  In children, wheat protein allergy tests could not tell apart those who reacted to wheat from those who did not.

• Nutrient absorption from food⁷

  In people, wheat protein was mostly digested, though the body held onto less of it than milk protein.

• Plant-based vs pork¹¹

  Seitan protein-based bacon had more protein than pork bacon in the study.

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 one finding in people. When most findings in people point one way, the page leans that way (“Mostly”), and every finding is still shown. Findings whose study type is not stated are shown but not counted.
