...series of experiments, scientists at Purdue University compared weight gain and eating habits in rats whose diets were supplemented with sweetened food containing either zero-calorie saccharin or sugar. The report, published in Behavioral Neuroscience, presents some counterintuitive findings: Animals fed with artificially sweetened yogurt over a two-week period consumed more calories and gained more weight - mostly in the form of fat - than animals eating yogurt flavored with glucose, a natural, high-calorie sweetener. It's a continuation of work the Purdue group began in 2004, when they reported that animals consuming saccharin-sweetened liquids and snacks tended...
...drinking water to fill up when we're hungry, for example, or opting for artificial sweeteners instead of sugar to get the same satisfying sweetness without the offending calories. But new research suggests that the body is not so easily fooled, and that sugar substitutes are no key to weight loss - perhaps helping to explain why, despite a plethora of low-calorie food and drink, Americans are heavier than ever...
...right? Opponents of bisphenol A say official safety figures are far too high, given what the chemical, which mimics the hormone estrogen in the body, does in animals. In the lab, even low exposure levels - adjusted for body weight - have been linked to a variety of sex-hormone-imbalance effects, including breast and prostate cancer, early puberty, miscarriage, low sperm count, and immune-system changes. Critics also claim that in developing infants, such sex-hormone effects may come into play at exposure levels far below what health authorities have deemed safe for adults. "The reproductive system is developing, the brain...
...tough to appeal to women, or Obama too white to appeal to blacks. When Hillary Clinton’s victory in New Hampshire was credited to a surge in feminine sympathy after a teary-eye moment on the eve of the election, pundits quibbled over the statistical weight of the “identity effect...
...fetal development is not new: A study in the Lancet in 2000 suggested, for example, that a mother's stress during pregnancy may increase the risk of congenital brain malformations in her baby. And it has been well established that severe maternal stress is associated with low birth weight and premature birth. Now, a new study by British and Danish researchers in this week's Archives of General Psychiatry examines the impact of stress - the acute, agonizing kind, such as that experienced with death or sickness in the mother's immediate family, and not the run-of-the-mill anxiety...
