The US goes straight to your hips

Is America’s weight problem an issue of bad genes or bad environment? A new study suggests the latter. Comparing Korean children who were adopted into American families versus European families, the authors found that American-adopted Koreans were significantly more overweight and obese, even controlling for sex, age, adoption age, and education. In fact, the difference in body-mass index between American- and European-adopted Koreans was about the same as the difference in body-mass index between Koreans living in South Korea and North Korea.
