Soy protein, do you really need it?
For women there is no problem, but for men, it’s a different story. Soy increases estrogen levels in men and lowers testosterone levels.
Testosterone is mostly abundant in men. It plays an important role in your health. It is responsible for the development of muscles and bones and sex drive. Testosterone also plays role in making blood stronger and many other functions. There are many natural ways to increase testosterone levels in men, and soy isn’t one of them.
Soy contains ingredients with estrogen-like properties that increase estrogen levels in men. It causes a reduction of testosterone levels. In women soy doesn’t have such an effect.
Soy will lower testosterone levels and also may lower sperm count. There are many protein sources, so you won’t be at harm if you avoid soy protein. On the contrary.
Soy became an ingredient in many products and “protein products”.
Be careful. Soy is very cheap and rich in protein. Around 52% of it is protein. Many of the protein bars and protein meals being offered on the market actually contain soy and the greater amount of their protein content comes from soy.
The same happens with protein powders. Make sure what kind of protein are contained in the product. Read the ingredients label. If it says that it contains protein but doesn’t state what kind, consider that it contains soy protein. Avoid.
Such products should be avoided by men. There are good quality protein powders which don’t contain soy protein at all. They are the smart choice.
Products that contain protein which doesn’t come from soy, may still have some amount of soy additive. It is the case with many other food products. Such soy additives are used for easier production and evenly emulsified texture. The minimal intake of such products will not have significantly negative impact on your hormones.
