For Women Only
Postmenopausal women seeking alternatives to synthetic hormones can enjoy their tofu with no worries. New studies suggest that diets high in soy, which contain estrogen-like compounds called isoflavones, will not increase the risk of uterine cancer. In a two-year study, women who consumed 58 milligrams of soy isoflavones daily showed no relationship between soy and excessive growth of uterine tissue. Research in monkeys also found that dietary doses of soy for the equivalent of 10 human years produced no evidence of endometrial overgrowth, which can lead to uterine cancer. The studies were presented at the Sixth International Symposium on the Role of Soy in Preventing and Treating Chronic Disease.
For Men Only
Testosterone supplementation may improve the quality of life for men with mild Alzheimer's disease, according to new research in the Archives of Neurology. Although the UCLA study did not find that testosterone improved cognition, in contrast to earlier reports, patients had higher scores on the quality-of-life scale reported by their caregivers. Participants were 16 men with mild Alzheimer's disease who received testosterone or a placebo during 24 weeks. Testosterone levels are being investigated in connection with Alzheimer's, since lower concentrations of the male hormone have been found in men who developed the disease.
Healthy and Fit
Now that the holidays are over and you've made that New Year's resolution to lose weight, defy the trend: More than half of U.S. adults are not physically active enough to reap any health benefits. According to the U.S. Centers for Disease Control and Prevention, 54.1% of adults do not engage in the minimum level of physical activity recommended for good health (at least a half hour per day). In addition, some Americans just don't want to. An online survey of 6,000 adults found that one-third of the population is disinterested in activities that might improve their health; another 29% say they only try to become fitter when forced by a health crisis. Only 30% said they regularly get off their butts and exercise.

Q&A
Q: Why do I eat so much junk food when I'm stressed out?
A: Eating a bag of Oreos or drinking a grande mocha may decrease production of the stress-related hormone glucocorticoid, according to a University of Cincinnati study on rats. The same effect was not shown with artificially sweetened snacks.

Remember Sex?
This earth-shattering bit of news does not apply only in the bedroom, but it certainly affects all aspects of a relationship: men and women don't think alike. Shocked? A new study has found that men and women use different areas of the brain when performing the same kinds of tasks. Researchers monitored brain activity using functional magnetic resonance imaging (fMRI) while 23 men and 10 women performed memory, verbal, visual spatial, and simple motor tasks. Finding that different regions of the brain are activated in men and women performing the same task has implications for a gender-specific focus to psychiatric research projects and other clinical situations.
