Study systematically reviews the impact of dietary antioxidants, vitamins C, E, and beta-carotene, on reducing the risk of type 2 diabetes, suggesting an inverse association with the disease, though no protective effects from supplementation were observed.
Research on the role of diet in the development of type 1 diabetes is generally of low evidence, but there are some high-quality studies indicating that longer breastfeeding and later introduction to gluten may reduce the risk of disease.
