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.

Diets high in saturated fat may enhance mineral absorption

This post includes a synopsis of a paper published in the International Journal of Sport Nutrition and Exercise Metabolism Volume 11, Issue 2, June and a recipe for mint and lime roast lamb.

Study title and authors:
Interactions Among Dietary Fat, Mineral Status, and Performance of Endurance Athletes: A Case Study

Fat: An Appreciation of a Misunderstood Ingredient, with Recipes
The study measured performance and mineral levels in male endurance cyclists who consumed diets of either (i) 50% carbohydrate, (ii) 50% polyunsaturated fat, or (iii) 50% saturated fat, for 28-day periods.

The study found:
(a) Endurance was impaired on the polyunsaturated fat diet
(b) Iron, zinc and possibly magnesium levels were lower on the polyunsaturated diet.
(c) Ferritin levels decreased on the polyunsaturated diet.
(d) Copper levels increased only on the saturated fat diet.

To conclude: Diets high in polyunsaturated fat may impair mineral absorption and lead to a reduction in endurace performance, whilst diets high in saturated fat may enhance mineral absorption.
