Thanks for the link, ISABELLA; I didn't see the program, but did read the article about it, so I have an idea of what he was talking about. There has been much thought about this for some time now; and there are a few different theories out there ...
Dr. Lustig of New York talks about the rise in infant obesity in his YouTube address too: he says that since babies don't eat fast foods & junkies, they must be getting the problem from somewhere else -- he believes from fructose sugars in infant formulas.
Then there were all the hormones and chemicals they fed to animals to FATTEN THEM UP -- people drank the milk and ate the meat & cheese, etc. Since we already know that diseases (remember Mad Cow disease) can pass from animals to humans, then so could those hormones and chemicals (and, possibly from mother to child too). Although, I do agree with those that say mother's milk does offer some benefits & protection to their offspring too.
Oddly enuff, someone just sent me an email today about the chemical MSG -- a very strong flavor enhancer that is put in most, if not all processed foods & fast foods. For some time, it has been used by scientists to make baby rodents fat for research on diabetes or other diseases. Harrumph!!!
It is very possible that they all may be contributing to the problem; and it may take a while before we sort it all out, but we may be on the right track for once ...
