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 investigated the relationship between cholesterol levels and death rates due to major causes. The study included 7,049 middle-aged men who were followed for 23 years.

The study found:
(a) Men with the lowest cholesterol levels, below 4.66 mmol/l (180 mg/dL), had a 141% increased risk of death from hemorrhagic stroke compared to the men with cholesterol levels up to 6.19 mmol/l (239 mg/dL).
(b) Men with the lowest cholesterol levels, below 4.66 mmol/l (180 mg/dL), had a 41% increased risk of death from cancer compared to the men with cholesterol levels up to 6.19 mmol/l (239 mg/dL).
(c) Men with the lowest cholesterol levels, below 4.66 mmol/l (180 mg/dL), had a 23% increased risk of death compared to the men with cholesterol levels up to 6.19 mmol/l (239 mg/dL).

The results of the study show that middle-aged men with low cholesterol are at greater risk of death from stroke, cancer and all-causes compared to men with higher cholesterol.
