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.

Soy consumption increases the risk factors for breast cancer

This post includes a synopsis of a study published in Cancer Epidemiology, Biomarkers and Prevention Prev October 1996 5; 785 and a recipe for bacon wrapped asparagus with cilantro flavored mayonnaise.

The Whole Soy Story: The Dark Side of America's Favorite Health Food
Women who produce nipple aspirate fluid (NAF) with normal cells are considered to have about a two-fold risk of breast cancer. Women who have abnormal cells in their NAF are considered to be at high risk of breast cancer (4 to 5 fold), see here. Abnormal growth of mammary epithelial cells have been associated with an increased risk of breast cancer, see here, and elevated levels of estradiol are a risk factor for the subsequent development of breast cancer, see here.
The study examined the effects of soy on normal pre- and postmenopausal women over a 12 month period. No soy was administered in months 1-3 and 10-12. Between months 4-9 the women ingested daily 38 g of soy protein isolate containing 38 mg of genistein.
The study found:
(a) Compared with nipple aspirate fluid volumes obtained in months 1-3, a 2-6-fold increase in nipple aspirate fluid volume ensued during months 4-9 in all premenopausal women. A slight increase occurred in postmenopausal women.
(b) Abnormal growth of mammary epithelial cells were detected in 29% of the women during the months they were consuming soy protein isolate.
(c) Compared with concentrations found in months 1-3 (no soy), estradiol concentrations were elevated during the months of soy consumption.  
To conclude: Soy consumption increases the risk factors for breast cancer.
