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.

Phytosterols such as sitosterol are inserted in high quantities (at 841 times than the average vegetable) in plant sterol based margarines such as Benecol and Flora proactive.

This study was conducted to evaluate if sitosterol levels seen in the general population are associated with the occurrence of coronary events. The ten year study included 159 men who suffered a heart attack or sudden coronary death (major coronary event), who were compared with 318 control subjects.

The study found:
(a) Men with the highest sitosterol levels had a 1.8-fold increase in the risk of a major coronary event compared to men with lower levels.
(b) Among men with a high risk of a major coronary event, high sitosterol concentrations were associated with an additional 3-fold increase in the incidence of coronary events.
(c) Men with a high sitosterol/cholesterol ratio had a 3-fold increase in the incidence of coronary events.

Assmann concluded: "Elevations in sitosterol concentrations and the sitosterol/cholesterol ratio appear to be associated with an increased occurrence of major coronary events in men at high global risk of coronary heart disease".
