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 saturated fat diets associated with virtually NO heart disease

This post includes a synopsis of a study published in the American Journal of Clinical Nutrition Vol 34, 1552-1561

The study investigated the effects of saturated fat in determining cholesterol levels and heart disease in two populations of Polynesians (Pukapuka and Tokelau) living on atolls near the equator.
The study found:
(a) The diets in both Pukapuka and Tokelau are high in saturated fat.
(b) Tokelauans obtain a much higher percentage of energy from coconut than the Pukapukans, 63% compared with 34%, so their intake of saturated fat is higher.
(c) The cholesterol levels are 35 to 40 mg higher in Tokelauans than in Pukapukans.
(d) Heart disease was virtually non-existant in both groups.
(e) The migration of Tokelau Islanders to New Zealand was associated with an increased risk for heart disease. After migration their diets changed - They ate less saturated fat and more carbohydrate.
To conclude:
Both groups ate diets high in saturated fats - and had no heart disease.
Tokelauans ate more saturated fat, had higher cholesterol - and had no heart disease.
After migrating to New Zealand, Tokelauans ate less saturated fat and more carbohydrate - and suffered from heart disease.
