Eating soy lowers testosterone. If you’re a guy and you want a nice pair of man boobs, eat plenty of this plant-based “meat”.
That generally applies to processed soybeans, tofu being one such product. Eating it in its green state, usually named edamame (in pods and shelled), is a much safer and healthier choice for soy.
Not only that. It contributes heavily to atmospheric CO2. I once went on a soy diet to lose weight and added a phenomenal amount of intestinal gas to the atmosphere. Soy beans are still beans, after all.
Have you noticed Asians, who consume the most soy by far, having moobs? I haven't. But I have noticed fat American men, most likely meat eaters, with moobs.
And the phytoestrogens in soy is not the same as the hormone estrogen in the human body.
