Vitamins B2, B6 and B12 supplements may lower type 2 diabetes risk
A study conducted by Kim V.E. Braun, Ph.D. and colleagues from Harvard University suggests vitamins B2 and B6 deficiency and supplementation of vitamin B12 may raise risk for type 2 diabetes.
Presented June 9, 2019 at Nutrition 2019, the study shows that men and women in the highest quintile of intakes of vitamin B2 and B6 were 10% and 11% less likely to be diagnosed with type 2 diabetes, respectively, compared to men and women in the lowest quintile of intake.
The study also reveals that high intake of vitamin B12 foods was associated with elevated risk for type 2 diabetes mellitus while vitamin B12 supplementation was linked to reduced risk for the health condition.
Study researchers explain that high intake of vitamin B12 foods may contribute to the increase in the risk of type 2 diabetes maybe because these foods are mostly animal meat-based foods.
Study authors suggest that DNA methylation has something to do with the development of type 2 diabetes. DNA methylation can be affected by methyl donor nutrients like vitamins B2, B6, B12, folate, and methionine.
But the study does not find any correlation between consumption of folate and methionine and the risk of type 2 diabetes mellitus.
The study was based on data from three major U.S. studies including the Nurses’ Health Study, the Nurses’ Health Study II and the Health Professionals Follow-up Study. （陆博士）
