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.

The study investigated the association of diet with the incidence of breast cancer. The study included 378 women with breast cancer and 1,070 controls.

The study found:
(a) Women that ate the most unfermented soyfoods had a 22% increased risk of breast cancer compared to women who ate the least unfermented soyfoods.
(b) Women that ate the most eggs had a 46% decreased risk of breast cancer compared to women who ate the least eggs.

The data from the study shows that unfermented soyfood consumption increases the risk of breast cancer whereas egg consumption lowers the risk of breast cancer.
