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 study analyzed the likelihood of nondiabetic subjects becoming diabetic according to their fasting blood glucose (FPG) and glycosolated hemoglobin (HbA1c) (hemoglobin A1C) concentrations. The study included 208 subjects who were followed for 1.6 years.

The study found that those nondiabetics who had fasting plasma glucose (FPG) at or above 6.1 mmol/l (109.8 mg/dL) and HbA1C levels at or above 6.1% were 5 times more likely to develop diabetes than those nondiabetics who had fasting plasma glucose (FPG) below 6.1 mmol/l (109.8 mg/dL) and HbA1C levels below 6.1%.

High blood glucose levels are caused by diets high in carbohydrates see here.

HbA1C levels can be lowered by a high fat/low carbohydrate diet see here
