<“Whether weak or strong, the estrogenic response of a chemical, if not overcome, will add extra estrogenic burden to the system. At elevated doses, natural estrogens and environmental estrogen-like chemicals are known to produce adverse effects. The source of extra or elevated concentration of estrogen could be either endogenous or exogenous. The potential of exposure for humans and animals to environmental estrogen-like chemicals is high.”

Natural Estrogens

Oncol Rep 1998 May-Jun;5(3):609-16 Maternal genistein exposure mimics the effects of estrogen on mammary gland development in female mouse offspring.

>Some phytoestrogens, such as genistein which is a major component in soy-based foods, and zearalenone, a mycotoxin found in agricultural products, have estrogenic effects on the reproductive system, breast and brain.

…

>Thus, our results suggest that genistein acts as an estrogen in utero, and may increase the incidence of mammary tumors if given through a pregnant mother.

>Our investigations have examined the effects of a range of natural dietary concentrations of the most potent plant isoflavonoid, coumestrol, […] In contrast, the 10-day coumestrol treatments produced significant deficits in the sexual behavior of male offspring.

Proc Soc Exp Biol Med 1995 Jan;208(1):6-12 Chemical studies of phytoestrogens and related compounds in dietary supplements: flax and chaparral.

>Flaxseed contains high levels of phytoestrogens. Chaparral has been associated with acute nonviral toxic hepatitis and contains lignans that are structurally similar to known estrogenic compounds.

"Stimulatory influence of soy protein isolate on breast secretion in pre- and postmenopausal women,"

>Instead, this pilot study indicates that prolonged consumption of soy protein isolate has a stimulatory effect on the premenopausal female breast, characterized by increased secretion of breast fluid, the appearance of hyperplastic epithelial cells, and elevated levels of plasma estradiol. These findings are suggestive of an estrogenic stimulus from the isoflavones genistein and daidzein contained in soy protein isolate.

[The effects on the thyroid gland of soybeans administered experimentally in healthy subjects]

>Hypometabolic symptoms (malaise, constipation, sleepiness) and goiters appeared in half the subjects in groups 2 and 3 after taking soybeans for 3 months, but they disappeared 1 month after the cessation of soybean ingestion. These findings suggested that excessive soybean ingestion for a certain duration might suppress thyroid function and cause goiters in healthy people, especially elderly subjects.

Cancer Res 1987 Mar 1;47(5):1333-8. Effects of dietary fats and soybean protein on azaserine-induced pancreatic carcinogenesis and plasma cholecystokinin in the rat.

>This study demonstrates that certain plant proteins enhance the growth of carcinogen-induced pancreatic foci and that this effect is considerably greater than the enhancement by high levels of dietary unsaturated fat. Furthermore, the enhancement by the raw soy protein isolate may be mediated by CCK; but this does not appear to be the mechanism by which the unsaturated fat, corn oil, enhances pancreatic carcinogenesis.

Environ Health Perspect 1997 Apr;105 Suppl 3:633-6 Dietary estrogens stimulate human breast cells to enter the cell cycle.

>"Our findings are consistent with a conclusion that dietary estrogens at low concentrations do not act as antiestrogens, but act like DDT and estradiol to stimulate human breast cancer cells to enter the cell cycle."

The pros and cons of phytoestrogens

>A recent prospective study in human infants observed that female infants on soy-based infant formulas exhibit estrogenized vaginal epithelium at times when their breast fed or cow based formula counterparts did not, suggesting estrogenic activity of the soy infant formula [28].

I mean I pieced it together.

I am not positive about the hormonal response from soy, but soybean oil is all over the place and causes digestion issues in humans. I'd double check the ingredients of things you eat to avoid it.

>Another big deal is that 90 percent (!) of soy today is also genetically modified.

>the case in point is that 99 percent of the soy products we’re consuming today are conventional, GMO and toxic to your system. For that reason, soy is bad for you.

>Now on the flip side, soy can be good for you if it’s an organic, fermented soy. And organic means that it’s not GMO. There’s no chemicals or fertilizers or pesticides.

https://draxe.com/phytoestrogens/

>Phytoestrogens exist in many foods, supplements and essential oils. Some of the highest concentrations can be found in, among other things: soybeans and soy products

I don't have any source with specific numbers on hand but iirc soy has an exceptionally high phytoestrogen content. Soy is used in increasingly many food products allowing it to sneak in to your diet. As I recall soy protein is bad as well

The issue with that theory, while mostly true, is that testosterone excess is converted into estrogen. So if you eat high-estrogen foods and then produce a lot of extra testosterone, it's all just gonna end up as an even bigger vat of estrogen.

>>125162

>Now on the flip side, soy can be good for you if it’s an organic, fermented soy.

Organic just has fewer estrogens. It's like drinking diet soda instead of regular soda. Fermented soy is the only safe form of soy. Even in estrogenic cultures like Japan, you'll find that most of their estrogen-producing foods are fermented which kills off most of the bad shit.

>Even in estrogenic cultures like Japan, you'll find that most of their estrogen-producing foods are fermented which kills off most of the bad shit.

I don't get this meme. They don't convert 100% of their soy into soy sauce, miso paste, and natto. There's still edamame, tofu, kinako, crackers made with soybeans, roasted soybeans on Setsubun, whatever that soy shit in unohana is, and so on. Just miso soup with tofu cubes for breakfast every day is enough to fuck them up.

On my last cut I was eating a lot of TVP because it's almost entirely protein and its cheap as fuck. It fucking destroyed my metabolism and gave me the worst gas ever.

Go ahead and fill your diet with TVP, then tell soy isn't poison. It's cheap and its almost all protein so if soy isn't bad for you, then what could be wrong with it?

There are phyto/xenoestrogens in lots of things. Plastic and soya both have dangerous amounts of xenoestrogens and should be avoided. Soya bean is a biological warfare agent that feminizes its victims, and our livestock eat it.

He's actually genetically superior. His body stops him from eating the soy poison.

How do you even live? I was shocked when I started searching food labels for soy. Soy oil is in pretty much everything. Even most breads "may contain" soy oil.

Of course the leaf is advocating soy.

Shouldn't you be looking after your wifes son and not posting on an image board.

>>125349

>>125193 Was a strongly anti soy statement. I only suggested eating it as proof of its toxicity. I myself didn't believe the negativity about soy until I was exposed to in high amounts.

>>125336 wasn't me

>>125345 was a legitimate question. Soy is in like 90% of the things on grocery store shelves. It's disgusting. Breads, salad dressings, most baked goods, any cheap product with "meat" in it usually says something like "vegetable protein" which you can assume is soy. I avoid that shit as much as I can, but it's an absolute minefield out there.

>>125351

>I only suggested eating it as proof of its toxicity.

Learn from the mistakes of others so that you don't have to repeat them.

>>125354

Some people just don't listen, and unless you eat a lot you probably won't notice the effects. To them I say, try it for yourself. I was eating about 80g of dehydrated soy a day for a month before I started reading up on the effects of soy and realized why I was feeling like such shit.

If people won't listen, then it's better to poison yourself once and learn from it than to only slightly poison yourself for the rest of your life.

Soybeans also have more pesticides than almost any other plant.

They need like 40 different bio-cides just to keep them alive now.
