Well you will get downvotes if you don't actually provide any evidence beyond "he looks funny". The whole beef hormone controvosy is complete bullshit; the EU has lost cases against the US & Canada in the WTO twice now, both times for lack of scientific evidence behind their decision. The ban happened when Europe was wrestling with mad cow disease, which in no small part influenced the populance against the scientific method with regards to food saftey. This, along with the fact that MEP's had recently been elected for the first time, made the decision almost entirely populist. The EU has _never_ justified the ban scientifically.

I don't have evidence that hormones in beef affect humans. Do you have evidence that they don't? Personally I would rather not eat it without such evidence.

I just quickly googled and found this on the website of the American Public Health Association: "By contrast, the US government position is that hormone residues in beef from adult cattle pose no threat to human health. This assumption of safety, however, has remained untested by long-term epidemiologic studies and instead relies on dated research concerning the ability of estrogen (estradiol) to mutate genes. This policy fails to reflect more recent research that hormones and hormonally active chemicals may exert their toxicity instead via epigenetic changes.12,23"

Do you carry a cell phone? Because a lot of people believe that carrying and using cell phones over long periods of time will cause cancer due to the long term exposure to electromagnetic radiation. There is no evidence that this is the case, however, nobody has proven that they DON'T. And not enough time has passed to really know the long term effects.

You're probably right, American teenagers are hitting puberty earlier too and growth hormones in milk and beef were the main suspects.

But also: When women have a large pool of potential mates to chose from they usually select the healthier larger males. In the USA we all speak the same language, use the same currency, can move to whatever city we want and that gives women a much larger selection of big males to mate with. While in European countries, there are language barriers, cultural barriers, and smaller populations per country. Although the population of europe is 700+ million, the population tends to stay in it's home country and intermarry with it's own kind to an extent. Meaning once all the big males in a country are married and taken, the women there start mating with medium & smaller men. That's my theory at least. American culture is also very extreme-masculine, homophobic, scared of looking weak, and obsessed with dominant macho males. It might have to do with white men's fear of strong dominating black men which are the majority in many physical sports and are over-represented in violent crimes and present in high-crime neighborhoods. So maybe it's a security thing.

I'm under the impression you're from Ireland judging by your username. Kids and adolescents that are well fed tend to grow more than those that aren't, and portion size in the US tends to be substantially greater than elsewhere, especially Europe. Also, there seems to be a greater focus on working out for aesthetic reasons in the US. All of this is, however, does appear to be changing, and moving more toward an American norm. You may also be suffering from confirmation bias! Or, you're right and something in American food is affecting growth rates, but there doesn't appear to be a lot of evidence to support this notion.

This phenomenon has been studied, but is currently thought to be because of lifestyle differences. See "The Health Toll of Immigration": http://www.nytimes.com/2013/05/19/health/the-health-toll-of-...

Americans have been 'larger' for some time. We had trouble with AK47s after WW2, for example, because they were too small for the comparatively larger American soldiers to wield comfortably.

I don't think it's any more complicated than the fact that we eat more food for all of our lives.

I'm not a doctor, so i wouldn't claim your theory is impossible. But we americans have a horrible diet, and we eat tons of food. I can't say much about height, but breadth comes from 1300 calorie fast food lunches.

Hormones and antibiotics, perhaps. Chinese raised in America do not look the same as Chinese raised in China. They tend to be bigger, thicker, taller, and with a different skin tone. Go figure.
