High vitamin D levels significantly reduce people’s risk of diabetes, new research suggests.
Lead author Dr Sue Park, from Seoul National University, said: ‘We found that participants with blood levels of [vitamin D] that were above 30 ng/ml had one-third of the risk of diabetes and those with levels above 50 ng/ml had one-fifth of the risk of developing diabetes.’
The researchers argue their findings suggest adults should have at least 30ng of vitamin D per millimetre of blood, which is 10ng/ml higher than the level recommended by the Institute of Medicine.
Some 77 percent of adults in the US are deficient in vitamin D, which is double the rate of 1980.
Previous research suggests vitamin D strengths people’s immune systems.
Type 1 diabetes is an autoimmune condition that occurs when a person’s body attacks the cells that produce insulin. Type 2 diabetes is more related to lifestyle factors, such as carrying too much weight.
