Animals natural Hormone production does not affect us drastically, but then again are we meant to consume baby food daily, AKA milk? It’s the stressed animals whose meat gets infused with cortisol, and studies show changes the nutritional quality of the meat.
The real problem is when man injects hormones, like bovine growth hormone, into these animals to make steers reach butcher weight faster. These hormones gets metabolized by our bodies as a xeno-hormone. Xenoestrogens found in herbicides that are consumed by animals can also affect us when we eat their meat or diary products. Exposure in childhood to Xenoestrogens are one of the factors in premature puberty.
