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.

This study assessed the changes in risk factor trends for coronary heart disease and stroke during a 20 year period in a population of 7,030.

The study found:
(a) Cholesterol levels in men aged rose by 13% over the 20 years.
(b) Cholesterol levels in women aged rose by 16% over the 20 years.
(c) Animal fat intake doubled and animal protein rose by almost a quarter over the 20 years.
(d) This rise may be attributable to an increased intake of meat, eggs and dairy products.
(d) Blood pressure levels decreased over the 20 years.
(e) The incidence of coronary heart disease did not change among men and women.
(f) The incidence of all stroke declined about 60% for both men and women.

To conclude: An increase in dietary animal fat and protein leads to an increase in cholesterol levels, no change in heart disease incidence, a decrease in blood pressure and a 60% decrease in stroke.
