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 was designed to test the hypothesis that higher cholesterol levels are correlated with slower Parkinson disease progression. Cholesterol levels were measured in 774 patients with early Parkinsons disease who were followed for 2 years. The study collected data on the number of patients with clinical disability requiring drug therapy (levodopa).

The study found that those with the highest cholesterol levels had a 25% decreased risk of needing drug therapy treatment for Parkinsons disease compared to those with the lowest cholesterol levels.
