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.

High-density lipoprotein cholesterol (HDL-C) is known as the "good cholesterol". The American Heart Association give the advice that it may help to prevent heart disease.

The objective of the study was to investigate the effect of reductions in total and saturated fat intakes on High-density lipoprotein cholesterol levels.

The study included 103 people of all ages and races who consumed one of three diets for 8 weeks.

The diets were either:
(i) 34.3% total fat,15.0% saturated fat (High saturated fat diet)
(ii) 28.6% total fat, 9.0% saturated fat (American Heart Association Step I diet)
(iii) 25.3% total fat, 6.1% saturated fat (Low saturated fat diet)

The study found that the more that total fat and saturated fat was reduced, the more that the protective High-density lipoprotein cholesterol was reduced. I.E. the low saturated fat diet reduced the protective High-density lipoprotein cholesterol the most. This applied to all types of High-density lipoprotein cholesterol.

To conclude: This study shows that a low fat diet increases heart disease risk.
