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.

What advice should the American Heart Association be giving regarding saturated fat?

The following paper was published in Current Atherosclerosis Reports 2011 Sep 8.

Study title and authors:
Effects of Diet on High-Density Lipoprotein Cholesterol.
Siri-Tarino PW.
Atherosclerosis Research, Children's Hospital Oakland Research Institute, 5700 Martin Luther King Junior Way, Oakland, CA, 94609, USA,

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

In this paper Siri-Tarino reviewed the effects of various diets on HDL-C levels.

Siri-Tarino found:
(a) Added sugars were associated with decreased HDL-C levels.
(b) HDL-C levels were increased by 4-5% with weight loss, omega-3 fatty acids, and a Mediterranean diet pattern.
(c) Replacement of dietary carbohydrate with polyunsaturated fats is associated with a 7% increase in HDL-C.
(d) Replacement of dietary carbohydrate with saturated fats is associated with a 12% increase in HDL-C. (Monosaturated fats effects were inbetween the polyunsaturated and saturated values)

On their own website the American Heart Association say that HDL-C is the "good" cholesterol which may help to prevent heart disease, and the scientific evidence says that consuming a high saturated fat diet will lift your HDL-C levels more than any other type of diet - so shouldn't the American Heart Association be telling us all to eat a high saturated fat diet?
