Delayed exposure to wheat and barley proteins reduces diabetes incidence in non-obese diabetic mice.

Dietary gluten, vitamin D3, and fish-oil are suggested to influence the incidence of autoimmune diabetes. To determine whether modification of their intake could reduce diabetes incidence and autoimmunity in mice, pups from female non-obese diabetic (NOD) mice were fed diets modified for protein source, fatty acid content, and/or vitamin D3 content and were followed for diabetes development, insulin autoantibodies (IAA), and insulitis. Replacement of wheat and barley with poultry as the major protein source significantly affected diabetes development.
