What's different between americans and other countries? The following is a list of causes that could have some effect:
1. You have genetic considerations - a very significant part of american gene pool is of african and latino extraction. Unlike europeans/asians who's ancestors lived in civilised societies with more abundant food for millenia and underwent selection, african and latino population until recently lived in much harsher environment where craving for fat, salt and sugar and ability to absorb those things were valuable survival characteristics rather than a detriment.
Similar consideration may apply not just to ethnicities but class composition of immigrants who came to US - though to a much lesser degree.
2. Significant part of US babies are formula-fed - and it was worse in previous decades. Very considerable part of those formula-fed babies are fed soy-based formulas. Besides valuable proteins soy products have a variety of biologically-active components. Some of them disrupt digestion of valuable elements like iron, zink and calcium - possibly making organism compensate by increasing total food intake which results in fat accumulation (formula-fed babies gain weight faster than breast-fed ones). Lack of the trace elements along with increased intake may disrupt the regulation for the rest of the person's life - making him more likely to be fat. The soy contains fitoestrogens - compounds that act like human sex hormones. Women are encouraged to eat soy to counteract the effects of menopause - so it must be strong.
Such a baby receives weight equivalent of 6-7 birth-control pills a day. How much it screws up the development - probably a lot.
Hormones and lack of nutrients most likely affect the brain development (explosion of ADD/ADHD in US kids) but that's another topic.
Besides soy-based baby formula, the use of soy products exploded in US over the last half-century.
3. All kind of crap that turns up in our food, medicine, materials, shampoos, etc. that is biologically-active - anybody's guess.
You can find a lot of info on the web on those topics.
Thrawn: - Americans spend more on fast food then, higher educationi, personal computers, computer software, or new cars.
So our education, computers, software and cars are very cheap - especially compared to other countries. The food is very cheap too.
How do you chaps think we should go about doing something about it?
We should stop socialist policies that screw up the natural selection.
