The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

The objective of the study was to examine the relationship between vitamin D status and incidence of type 2 diabetes. In the study the vitamin D levels of 3,066 men and women were analysed for 7 years.

The study found that those with the highest vitamin D levels had a 40% decreased risk of diabetes compared to those with the lowest vitamin D.
Vitamin D can be obtained from sunshine and foods. Interestingly, foods that provide this vitamin - all of which are animal foods, such as butter,eggs, liver, organ meats and seafood - tend to be high in cholesterol. In fact one of cholesterol's many functions in the body is to act as a precursor to vitamin D.

So, no cholesterol and no animal foods = low vitamin D. Therefore low vitamin D = higher rates of diabetes.
