Thoughts on Soy?

I'll eat fermented soy in small amounts.

Soy contains phytoestrogens, (plant estrogens) that act like human estrogen in the body. Too much is not good. Eating in moderation should be fine.

I have lots of soy. ( soy milk, tofu, TVP.... ( i would have tempeh, but can't get it easily)
Often 200 g in a sitting. Tofu).
Never noticed any bloating.
I have however noticed very noxious gasas if i have too much tvp and dont drink enough, but thats more of an excess protein, not enough hydration issue.

I'd say try soy if it doesn't agree with you move on, but no reason to avoid it otherwise.

Plant oestrogen is different from animal oestrogen and shouldn't make a difference if you consume it.
I've been drinking 300ml-1000ml of soy milk nearly every day over the past few weeks, and apart from occasional stomach irritation, it has caused me no problems as far as I can tell.

I have soy every other day with my cereal for breakfast. My stomach goes insane if I have milk, so if I want ice cream.. I really have to be careful how much I consume.

Sorry, this is not correct.

There is much confusion in the literature regarding phytosterols. There are some plants which are purported to be "hormonal" or "estrogenic", but contain no phytosterols. The confusion arises because plant constituents other than phytosterols sometimes exert an estrogenic, or progesteronic effect . Estrogen is unique in this as most other hormones and adrenocorticoids require precise molecular shapes to bind to receptors. Numerous substances, however, seem to be able to complex with estrogenic receptors.3,4 Additionally, some botanicals have been found to act on the brain and effect hypophoseal hormone release without containing steroidal constituents. For example, porphyrin constituents in the Wild carrot, Daucus carota are shown to stimulate the pituitary to release gonadotropins. 5. Other constituents are smooth muscle antispasmodics to the uterus, and others effect circulation to the uterus and pelvis. Some authors use the term phytoestrogen to refer to any constituent that has an estrogenic effect, while others reserve the term for those estrogenics that are specifically steroidal in nature . As we shall see, many different chemical constituents, not only the phytosterols, can effect hormonal metabolism and action of the reproductive organs in animals. We will also examine what action the sum total of all the constituents, in any individual botanical species has on the human organism. We will seek to note a particular essence or specific indication of plants studied. The chemicals are only an indication of the energy the plant posesses.

The effects of numerous substances in plants in the human body are still being studied. But there are countless botanical creams and pills that contain these plants, and I can assure you (from first hand experience) that they exert a powerful effect in the human body.

Soy does seem to provide some benefit from Japanese studies, where SMALL amounts of it are being eaten daily. That is a completely different scenario than here in the US, where people regularly drink or eat massive amounts of it as an animal product replacement. That is why I say use it in moderation. That means, eat a little every day. But don't drink gallons of soy milk, eat soy ice cream, and assume it is not effecting you. And the same goes for men, because they have estrogen receptors too.

Sorry, this is not correct.

"phytoestrogens mimic estrogen only very weakly. A number of clinical studies in men have cast doubt on the notion that eating soy influences testosterone levels to any noticeable extent. And most large studies of soy intake and breast cancer rates in women have not found that it causes any harm, said Dr. Anna H. Wu of the Keck School of Medicine at the University of Southern California." (http://well.blogs.nytimes.com/2013/09/27/ask-well-is-it-safe-to-eat-soy/?_r=0)

"No significant effects of soy protein or isoflavone intake on T, SHBG, free T, or FAI were detected regardless of statistical model.
The results of this meta-analysis suggest that neither soy foods nor isoflavone supplements alter measures of bioavailable T concentrations in men." (http://www.sciencedirect.com/science/article/pii/S0015028209009662)

Soy is fine. It's a regular part of my diet, both soy milk for smoothies and tofu (miso soup )

For the non-vegetarians out there, or heck- even those that are... what is your take on soy products? Ive heard it causes bloat, weight gain, but also good for you. Okay- GO!

I have never heard of any of this. unless you have some sort of allergy to soy, I wouldnt worry.

Many people demonize these foods due to the fact they want to find a reason they are not losing weight.

fermented = yes (like miso and tempeh, etc)...otherwise I don't touch the stuff.

Too much is not good.

How much is "too much" though?

Too much is not good.

How much is "too much" though?

More than enough, but less than way too much.

Indeed, given that it's a staple of eastern diets this strikes me as a "0.01% to 0.02%" becoming a "shock horror, risk doubles" type situation.

So, basically this research is showing that isoflavone and soy do not effect Testosterone levels? Gee, what a surprise, since it is an ESTROGEN mimetic. In case you hadn't noticed, the OP is a woman. And yes, we know that soy, isoflavenoids and various other plant sterols do interact with our receptors. Researchers are still looking into the strength of the interactions, and apparently is one Doctors opinion that the reactions are weak. That would be a good reason why eating a small amount of soy a day is not a problem (as I already said) But doctors warn women with estrogen sensitive cancers to stay away from these estrogen mimetics, because they will increase metastisis in HER2 + breast cancer cells.

As a man, you have estrogen receptors too. If you want to drink soy like it is milk, be my guest. But you are increasing the risk of putting on fat in the same places women do, and increasing your risk of estrogen sensitive breast cancers as well.

This was never about testosterone, but that was interesting anyway, thanks.

Soy sauce on everything if you're Asian!!!! As for soy milk, soy protein, etc. ..................blech IMO.
