Researchers from Warwick Medical School have said that people who get plenty of vitamin D from sunlight have a 55% lesser risk of developing diabetes than those who do not.
The researchers reached this conclusion after analyzing 28 existing studies on almost 100,000 people, which examined the effect of vitamin D on cardiovascular disease, Type 2 diabetes and metabolic syndrome. It found that high levels of vitamin D reduced heart risk by 33%, diabetes risk by 55% and metabolic syndrome risk by 51%.
"The research we conducted looked at naturally-occurring vitamin D rather than supplements," said co-author Dr Johanna Parker. "Most - 90% - of your vitamin D comes from sunshine so we recommend sensible sun exposure in the summer. People should expose themselves for 30 minutes twice a week - this means exposing the face and arms with no sunscreen."
The study said that eating vitamin D-rich food like tuna and mackerel also helped. The details appear in the journal Maturitas.
