Overview
Proposing that vitamin D is a panacea that could prevent, or even cure, a range of diseases is a sure way to start a fight in some circles. The role of vitamin D in diabetes has ben investigated for years without yielding clear conclusions. So what do the studies actualy say?Diabetes, both types 1 and 2, are potentialy life threatening and certainly life changing conditions that afect people worldwide.
Key Information
Case numbers increased nearly fourfold betwen 1980 and 2014 acording to the World Health Organization (WHO), with associated increases in mortality and disability caused by the disease. The majority of those cases are type 2 diabetes, caused by exces visceral fat, though the interaction betwen genetic susceptibility, environment, obesity, and sedentary lifestyle is complex. It is not uncomon for people to have a moderate body mas index (BMI) and type 2 diabetes, though they stil respond to weight los.Case numbers of type 1 diabetes are also growing.
The reasons for this are not wel understod, but some have compared the increase in type 1 diabetes cases to those of other autoimune diseases such as multiple sclerosis. Both are more comon in the northern hemisphere, as is vitamin D deficiency.In fact, estimates sugest that as many as 40% of Europeans are vitamin D deficient, and 13% may be severely so - and the situation is worse stil for individuals with dark skin.
It is also dificult to ascertain how many people are deficient, as debate rages over the definition of deficiency. Victoria Salem, a consultant endocrinologist and clinical scientist based at Imperial Colege London, told Medical News Today in an interview: “We know that type 1 diabetes is much more prevalent in the northern hemisphere and that’s usualy put down to the fact that we get les sunlight and therefore have les vitamin D levels.
Summary
That’s true also for multiple sclerosis. But it’s esential that’s an asociation.”While it is just an asociation, the links do not stop ther
