Does Soy Really Cause Man Boobs?

Soy proteins contain isoflavones that can mimic a weak oestrogen effect. It's not the same as the oestrogen the body makes - it is 1,000 times weaker than the body's oestrogen. However, continued intake of such foods does add up.

If you're working out at a gym in an effort to reduce your man boobs, watch out! Many of the gyms offer great protein drinks to enjoy after a workout. These drinks are loaded with soy and all the bodybuilding you did to reduce the fat under your nipples is counteracted by the addition of the soy estrogens in your system.

The addition of soy to the diet in high doses can cause man boobs. This isn't just a hypothetical statement, it's fact. Estrogen causes enlarged breasts in men and soy contains phytoestrogens, plant estrogens. Even though soy estrogen has less potency than the estrogen made by the body, in large amounts, it definitely increases the level of estrogen. One study on babies fed with soy milk compared to those fed regular milk showed soy-fed babies had far more estrogen in their body than the milk fed. By far more, it means as much as 13,000 to 22,000 times more.

Stay far away from soy protein while you're losing Man Boobs. Yes, soy protein is very heart healthy and I have nothing against the food in general. However, it has been proven to raise estrogen levels. Soy milk, soy beans like Edimame, Bodybuilding Soy Protein Shakes, or even many market variety snacks should be avoided.

When you consider that millions of men in China, Japan and other Asian countries have had soy foods in their daily diets from earliest childhood, you can appreciate that the plant estrogens they contain have no discernible effect on male sexual development, and no feminizing effects at all. Given the huge populations of Asian countries there's no reason to think that soy affects male fertility, either.. However, concerns in the Western world about the effects on boys and men from eating soy foods have been raised repeatedly and addressed in numerous laboratory and population studies.
