Non-O blood types are at higher risk of type 2 diabetes
When French researchers analyzed data from some 82,000 women in 2015, they found that those with type A blood were 10 percent more likely to develop type 2 diabetes and those with type B blood were 21 percent more likely to develop the disease.
The scientists hypothesize that a person’s blood type may play a role in their gut microbe makeup, which could, in turn, affect metabolism and contribute to diabetes risk.
