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 examined the relationship between cholesterol levels and statin use in relation to Parkinson's disease. The study included 15,792 participants, aged 45-64 years, who were followed for 11 years.

The study found:
(a) Statin users had a 139% higher risk of Parkinson's compared to non-users.
(b) Those with the highest cholesterol had a 57% reduced risk of Parkinson's compared to those with the lowest cholesterol.

Professor Huang concluded: "Statin use may be associated with a higher Parkinson's disease risk, whereas higher total cholesterol may be associated with lower risk".
