If you are vitamin D deficient, you are up to five times more likely to develop diabetes.

“People deficient in vitamin D might have a greater risk of developing diabetes, report researchers in a new study.

Researchers at the University of California San Diego School of Medicine and Seoul National University studied 903 healthy adults without pre-diabetes or diabetes during clinic visits from 1997 to 1999, and followed up with them for 10 years, to study their levels of 25-hydroxyvitamin and their medical condition. Their findings were published this week in PLOS One.”

Moderate sunlight and increased intake of foods containing vitamin D will be enough for most people. If you live in a cold part of the world or are dark skinned, you may also need supplementation.

If you are in doubt, especially if you are over forty or pregnant, check with your doctor. A real medical doctor, not some unqualified “health professional.”
