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.

Bar-El notes that endocrine disrupting compounds (EDCs) alter the function of the endocrine system and consequently cause adverse health effects. Phytoestrogens, natural plant compounds abundantly found in soy and soy products, are considered to be endocrine disrupting compounds.

In a review of the literature Bar-El found:
(a) The evidence for the alleged beneficial effects of phytoestrogens are indirect and inconsistent.
(b) Lifetime exposure to estrogenic substances, especially during critical periods of development, has been associated with formation of malignancies and several anomalies of the reproductive systems.
(c) Phytoestrogen consumption in infants, through soy-based formulas, is of particular concern.

Bar-El concludes that the possible adverse effects of phytoestrogens should not be taken lightly.
