So, why does drinking milk and eating meat increase the chance of twins?
Insulin-like growth factor (IGF) may be the culprit. What’s IGF? It’s a normal growth factor. Specifically, it’s the protein that’s released into the bloodstream of animals (humans included) from the liver in response to the growth hormone. It winds up in the animal’s milk. IGF is thought to increase ovulation by increasing the sensitivity of the ovaries to follicle stimulating hormone. In some studies, IGF has been credited with helping embryos survive in the early stages of development. The Cancer Prevention Coalition believes that IGF-1 increases to unhealthy levels with the use of r-GBH, the genetically engineered growth hormone some farmers use to increase milk production in cows. One might think that the human digestive process would destroy IGF-1, but that’s not true. Instead, our intestines absorb IGF-1. In fact, more research has shown that it can be absorbed into the bloodstream where it can affect other hormones. Some studies have shown that increased levels of IGF-1 lead to
