Obesity levels have risen dramatically in research animals and others living close to humans, suggesting environmental factors are encouraging everyone to gain weight, according to new findings in the Proceedings of the Royal Society B.

Darn these Americans, now it's animals, what's next? the fish?

All 24 populations of animals, which ranged from primates housed in research facilities to feral rats living in the greater Baltimore area, showed significant increases in body weight.
A question I have about this study is how many of these 24 populations of animals live in close proximity to human beings? Eating human garbage might be another clue as to why they are getting fatter....
Canadians, living in close proximity to Americans, have an obesity rate that has risen to half the American rate already. How Canada has remained so close to the USA for so long, and still has only half our obesity rate (16% vs. 32%) remains a mystery.
Mexicans have the second highest obesity rate in Latin America (after Panama), probably due to the spillover of American dietary habits. However, Mexico's obesity rate is lower than that of the USA. As a result, it can be presumed that the US obesity rate would be higher than it is, if so many Mexicans were not here to slim down the average.
The countries in the world with the highest obesity rates are Qatar, Lebanon, Panama, the only countries where both men and women have higher obesity rates than the USA.
The thing is, laboratory rats and mice are supposedly given a fixed diet, and records were kept over the years. This is a head scratcher. Maybe the food for lab critters changed, even if they gave them the same amount.

Hmm .... maybe part of evolutionary genetic expression changes i.e. genetic drift.
I think grains and so forth have been tinkered with for years, to get more nutritional bang for the buck.
From my understanding is that wheat today is different than the ancient sumerian wheat going back some 5,000 years ago and possibly longer and so maybe that's why millions of humans have grain intolerence/celiac disease.
