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.
