A co-worker claims that consuming any reasonable amount of soy and/or soy products will promote estrogen levels in men and will cause those annoying consequences associated with estrogen. Is there any truth to this?

Many plant products contain estrogen.

Soy products have long been consumed in Asia without men developing breasts etc.

I've heard this rubbish before, it used to be used to attack vegetarianism and has as much truth as arguements suggesting all vegetarians are pale and thin...

Women entering menopause are prone to estrogen surges with periods of depletion. Soy is recommended for women entering menopause because it allegedly regulates estrogen distribution. It doesn't create the stuff or cause more production. Women just entering the premenopausal years are subject to surges of estrogen and then depletions. Hence the need for regulation of distribution.

Women in premenopausal status are also urged to stay away from high fat foods such as fatty meats and dairy becomes suspect in a cancer equation. Soy is a great alternative source of protein and soy beverages are calcium enriched in order to address the need for extra calcium.

No my friend, you will not grow boobs or get femme features from using soy but it is good for you.

The way I understand it soy and other isoflavine food and herbs have weak estrogen effects so when they occupy estrogen receptor sites in the body they prevent stronger estrogens from binding to those sites and exerting their effect.So for males some is probably OK but I wouldn't overdo it.

All beans have these 'phyto-oestrogens'.

People in Brazil virtually live on beans - this doesn't seem to have affected the birth rate.

I read somewhere that phyto-oestrogens are beneficial as they reduce the level of iron in the blood, high iron levels creating higher blood pressure.

You are probably right about the phytoestrogens .In fact the bigger concern is probably the increased exposure to environmental estrogens from petrochemical products and in soaps,pesticides,plastics etc.U.S. male fertility rates have been dropping at the same time as exposure to these has been increasing so to the extent they are blocked by weaker phytoestrogens it is probably a positive.
