There is no shortage of studies on how our food supply affects children and the fact that we are living longer healthier lives today with, according to you, a diet filled with unnatural foods, is all the proof you need that your fears are unfounded.
Trying to feed people with foods not containing naturally occurring endocrine disrupters today would be nearly impossible and would serve no purpose. If the naysayers could show any ill effects from consuming these volatiles, they would. They can't but that doesn't make them any less vocal. Everything you eat today, save some wild fish and some tree nuts, has been genetically modified in some way. Man-made and unnatural food, as you refer to it, is what makes up our food supply and here we are living longer and healthier lives than at any other time in our history.
Yes, but people have to live out their adult lives with how their body develops during childhood, so those years are particularly important yet rarely studied carefully. You can often tell if a young Chinese woman spent her teen years in China or America by the size of her chest, while in the rest of her body there is not such a dramatic difference. Does anyone know why this is so? It might simply be more calories, or it could be hormone signals in the American food that is not yet present in China. This is visible hard evidence of something non-genetic going on. If not differences in food, what is your explanation?
