Soy and estrogen

I've heard somewhere that the consumation of soy-based products increases the estrogen levels of a human being, particularly for males. Is there any truth to this?

Thanks in advance.
 
"Soybeans also contain the isoflavones genistein and daidzein, types of phytoestrogen, that are considered by some dietitians and physicians to be useful in the prevention of cancer and by others to be carcinogenic[68] and endocrine disruptive.[69][70]" -Wikipedia

As with most health issues, you can find arguments for both sides. Obviously, one side must be incorrect, but finding out which is often difficult without having expert knowledge. This is one of the rare and unfortunate cases where the credibility of the source comes into play. I think most skeptics will be more inclined to think that soy is fine because it is approved by official sources and typically disparaged by what I would consider more independent sources. I don't think the FDA and the like have a good track record when it comes to health, and there exist economic conflicts of interest within the industry, especially if we are talking about an industry as monopolized and rigidly controlled as US agriculture.

I'm not a fan of soy and don't use it, personally.

Yes, that's correct it's not good forumula to give to babies but it's NON-fermented soy like soybeans, tofu etc. that contain estrogen.

FERMENTED soy is a much better option like misou and tempeh. I think what's been misunderstood in the west is that soy is a huge part of the Asian diet but that's just not true.

Hmmm. This guy is the author of "Beating Cancer with Natural Medicine", in which he calls conventional therapy "cut, burn and poison".

He does go on to state that his natural cures should be used in conjunction with conventional therapies, but the above is fairly inflammatory and makes me suspect his motives. I admit I have not read the whole treatise, only parts of it.

From his book, the pdf of which is available on his site:

Natural medicine is the “true” medicine
that is time-tested and has been around for centuries. It fact, it is radical only in its common sense approach.​
 
I don't know much about it, but wanted to ask if it is true that a quarter of US babies are fed soy formula as it states in this article? It is advised only for those who cannot tolerate breastmilk or cows milk based formula in the UK.

Did you read that correctly, or did I misinterpret your post (or the article)?

From the article:

Donovan said it's an important question to ask because almost 25 percent of formula-fed babies in the United States consume soy formula.

I took that to mean, of those who formula feed, almost 25 percent use soy.

But I often misread/misinterpret. :o

I mistyped, I meant to say of formula-fed babies - but still, its a heck of a lot - the breastfeeding rate isn't so good in the US (or the UK for that matter).

Some of the isoflavenoids in soy actually block oestrogen receptors, which is why it is thought that countries like Japan and China have such low levels of breast cancer.

Not all breast cancers are due/fuelled through oestrogen, but it is a fairly high percentage if my memory serves me correctly, and breast cancer drugs like tamoxifan, work as oestrogen analogues or block the oestrogen receptor.

The amount of soya your would have to eat as an adult male to have an effect on your testosterone would be fairly substantial.

Like everything, the poison is all in the dosage.

Okay, thanks. :)

A quick search found this:

Breastfeeding Among U.S. Children Born 1999—2007, CDC National Immunization Survey

Color me surprised. I don't have children, and am over 50. But almost all of my gal pals did breast feed their children.

I would agree with his analysis that in the west we consume much more soy than the east, and its processed differently.

On the issue of infants and soy, heres a study from pubmed

It's also very misleading. For instance, he compares the caloric intake from pork and soy. But anyone who's lived in Asia or spent more than a couple of weeks there will know that many Asians eat very fatty pork, which increases the average caloric intake per gram, and of course, soy is low in carbohydrates, so its relative caloric value is pretty low and certainly far lower than pork, particularly the sort of fatty pork eaten through most of Asia.

I'd also like to know what he means by "Asia". If he's including India then it isn't surprising that the Soy intake is low.

Having lived in China for 5 years and travelled extensively around the country, I can tell you that tofu is a staple in a great many areas. It's rare for a Chinese person to go a day without having a tofu dish, and the Japanese consume even more than the Chinese.

Tofu is unfermented soy, and the Chinese also often drink soy milk for breakfast, which is unfermented soy beans, ground up and boiled in water, so his assertion that the Chinese don't eat unfermented soy is utter cobblers!

I can't say much about the science, but most of his assertions about the Asian diet are just complete crap.

Wollery, I'm glad you posted. It's great to have input from someone who lives in China. I like most Americans, would have no way of knowing if unfermented soy was a staple or a condiment like Dr. Lam or others claim.

I believe in freedom of speech but folks like Dr. Lam really test that belief sometimes. He has to have known that he was lying or that he did so little research that his input was at best worthless. Sometimes I think there should be a legal penalty for that, but if there were it could lead to potentially shutting down communication about controversial or little known areas.
