Is soy milk bad for my testosterone?!

Soy in moderation is ok for most people. Soy does contain hormones. Soy is promoted to women for menopause symptoms, linked to early fertility in girls and low sperm count in men and can affect your thyroid. So I wouldn't be surprised if it affects testosterone.

Health agencies in several countries (Germany, France....) have issued health warnings about soy consumption.

If you don't already have thyroid problems or a family history of them, some soy is probably ok. But if you're eating a lot, cereal, milk, burgers, hot dogs, mayo, cooking oil, etc., you probably should consider cutting back.

Clinical studies show no effects of soy protein or isoflavones on reproductive hormones in men: results of a meta-analysis.

Generations have eaten soy has a stable food. Soybeans were a crucial crop in eastern Asia long before written record. soybeans have been used in China for 5,000 years as a food and as part of drugs. From about the 1st century AD to the Age of Discovery (15-16th century), soybeans were introduced into several countries? such as India, Japan, Indonesia, the Philippines, Vietnam, Thailand, Cambodia, Malaysia, Burma, Taiwan and Nepal.

Daisy still wants to bring up soy and its imaginary estrogen. Estrogen is an animal hormone only made in vertebral animals and some insects. Phytoestrogens are not a hormone, they are estrogen-like chemicals made by virtually ALL plants, not just soy. That means that are hand seasonings, grains (soybeans, wheat, rice, vegetables (beans, carrots, potatoes), date, pomegranates, cherries, apples, coffee etc. Animals even are found to have it.

Soy is very healthy for you. Even the FDA , American Heart Association, APA, and other other organizations and agency have said that eating more than 25 g of soy and soy0based foods can lower cholesterol, chill hot flashes, prevent breast and prostate cancer, and aid weight loss. Even the FDA Back in 1999, the Food and Drug Administration let companies claim that foods containing soy protein "may reduce the risk of heart disease."

These chemicals mimic or interact with hormone signals in animals. However, phytoestrogens don't always mimic estrogens. In some tissues they actually block the action of estrogen. If such estrogen-blocking action occurs in the breast, then eating soy could, in theory, reduce the risk of breast cancer because estrogen stimulates the growth and multiplication of breast and breast cancer cells. But studies so far haven't provided a clear answer, with some showing a benefit and others showing no association between soy consumption and breast cancer. In fact, a handful of unsettling reports suggests that concentrated supplements of soy proteins may stimulate the growth of breast cancer cells. Timing of soy intake may make a difference: The Shanghai Women's Health Study, for example, found that women with the highest soy protein intakes throughout adolescence and early adulthood had nearly a 60 percent lower risk of pre-menopausal breast cancer than women with the lowest intakes.
http://www.ncbi.nlm.nih.gov/pubmed/11431…

A 1995 meta-analysis of 38 controlled clinical trials showed that eating approximately 50 grams of soy protein a day in place of animal protein reduced total cholesterol levels by 9.3 percent, LDL cholesterol by 12.9 percent, and triglycerides by 10.5 percent.
I guess Daisy also forgot to mention the considerably high amount of estrogens in cow milk, conventional or not, responsible for hormone-dependent cancers. (Those include cancers of the testes, prostate, and breast.) The link between cancer and dietary hormones - estrogen in particular - has been a source of great concern among scientists.

1st, She forgot say that the natural estrogens are up to 100,000 times more potent than their environmental counterparts, such as the estrogen-like compounds in pesticides and phytoestrogens. ...we are mostly concerned about cow's milk, which contains considerable amounts of female sex hormones. Because of unresolved concerns about the risk of ovarian and prostate cancer, it may be prudent to avoid higher intakes of dairy products.

Part of the problem seems to be milk from modern dairy farms, where cows are milked about 300 days a year. For much of that time, the cows are pregnant. The later in pregnancy a cow is, the more hormones appear in her milk.

2nd: She didn't say that established evidence says that milk inhibit iron absorption, especially iron(non-heme) from plant foods.
Daisy didn't mention that the calcium in milk is not very bioavailable in the human body seeing that only has only 20% absorption, according to Foods & nutrition encyclopedia, Volume 1 By Audrey H. Ensminger. MIT says it has 20-30%. http://web.mit.edu/athletics/sportsmedic…
Vitamin D and magnesium is more important than calcium. vitamin D plays a critical role in maintaining bone health and is needed in calcium absorption.Several studies have shown that a high intake of vitamin D reduces fractures in the elderly. Vitamin D deficiency is why causes calcium and phosphorous excretion. Magnesium is needed for calcium absorption because it works with calcium in muscle contraction and relaxation. It also works with vitamin D, potassium and other minerals.

Soy milk does have some levels of estrogen in it. I don't think you're drinking enough, but if consumed in large amounts then yes, it can lead to low sperm count. It's still not the best thing to drink, try about that much water a day. I wouldn't be overally-concerned though.

soy milk is bad for you if the soy isn't fermented, check the label, I don't know about testosterone, I just know that over all it needs to be fermented.

A quart of anything other than water is unhealthy for you. Tone it down to a cup or so per day. Plus, cutting back is much more cost effective.

Soy milk is absolutely healthy to drink. Enjoy your milk and get back to your daily work routine.

No, soy Milk will not have any negative aspects on your health.

no more than cows milk.
