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 various factors that are associated with the risk of stroke. The study included 2,302 subjects aged 40 years or older who were followed for 15.5 years.

Regarding cholesterol levels, the study found:
(a) In men, every 1.21 mmolL (46.7 mg/dL) increase in cholesterol levels was associated with a 13% decreased risk of stroke.
(b) In women, every 1.21 mmolL (46.7 mg/dL) increase in cholesterol levels was associated with a 1% decreased risk of stroke.

The data from the study indicates that higher cholesterol levels are associated with a decreased risk of stroke.
