Pesticide in womb may promote obesity, study finds
One-quarter of babies born to women who had relatively high concentrations of a DDT-breakdown product in their blood grew unusually fast for at least the first year of life. Not only is this prevalence of accelerated growth unusually high, but it’s also a worrisome trend since such rapid growth during early infancy has — in other studies — put children on track to become obese.

Pernicious influences on dietary choices
Because humanity developed during eons of cyclical feasts and famines, we survived by chowing down on energy-dense foods whenever they became available. Today that's all the time. But a number of recent studies point to additional, less obvious influences on what and how much we choose to eat.

The Institute of Medicine periodically issues recommendations on what people should eat to be healthy and maintain a reasonable weight. Americans have largely ignored this well-intentioned advice, a new study shows. It reports that “nearly the entire U.S. population consumes a diet that is not on par with recommendations.”

Using DNA from fecal samples, researchers show that the infection was not passed to Homo sapiens by its closest primate relative.
