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.

Wolf notes that low calcium is linked to high blood pressure, colorectal cancer, bone loss and the risk of osteoporosis.

The purpose of this study was to examine factors that affect the efficiency of calcium absorption in women. The study included 142 healthy pre- and perimenopausal women, aged 46-54 years, (93.7% were premenopausal).

The study found:
(a) Women who consumed the most fat, absorbed calcium more efficiently than women who consumed the least fat.
(b) Women who consumed the least fibre, absorbed calcium more efficiently than women who consumed the most fibre.
(c) Women who consumed diets with the lowest ratio of fat to fibre had 19% lower calcium absorption values than did women who consumed diets with the highest ratio of fat relative to fibre.
(d) Women who had the highest vitamin D levels, absorbed calcium more efficiently than women with the lowest vitamin D levels. (Vitamin D is only found in food of animal origin such as lard, fish, butter and egg yolks).

The results of the study show that a high-fat diet helps women to efficiently absorb calcium.
