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.

Fivefold increase of bioavailable carotene when fat is added to the diet

Published in the J. Nutr., 65: 115-127 1958

Carotene balances on boys in Ruanda where vitamin A deficiency is prevalent
Roels OA, Trout M, Dujacquier R.

This paper can be accessed at:

Roels studied boys in Ruanda and found that when they received 200g of carrots a day, less than 5% of the carotene was absorbed. If 18g of fat was added to the 200g of carrots then 25% of the carotene was absorbed.

Roels concluded that: "An addition of fats to the diet may contribute to the relief of vitamin A deficiency".
