Flavor Not Worth Pounds

1 MSG Tied with Weight Gain

The flavor enhancer monosodium glutamate (MSG) is associated with weight gain, suggest researchers from the University of North Carolina, Chapel Hill. The research, which involved more than 10,000 adults in China, was published in the American Journal of Clinical Nutrition. The 5.5-year study found that those who ate the most MSG (median 5 grams daily) were around 30 percent more likely to become overweight compared with those who ate the least amount of MSG (less than one half gram daily). The link held even after researchers accounted for total number of calories consumed. Researchers say that those who consumed more MSG produced more leptin, a hormone that regulates appetite and metabolism. They believe that MSG could cause leptin resistance.

Yields High Levels of Superoxide

2 Long Term Estrogen Exposure May Raise BP

Researchers at Michigan State University have found that chronic estrogen exposure increase the production of the reactive oxygen species superoxide which disrupts the rostral ventrolateral medulla (RVLM), the area of the brain regulating blood pressure. Two sets of experiments using two groups of rats, one implanted with estradiol-17β (E2) for and a control group. The second set of animals had the anti-oxidant resveratrol added to their food. After 90 days, the RVLMs were harvested and examined. The E2 group in the first set had higher RLVM superoxide levels and BP compared to controls. Resveratrol decreased superoxide production and BP in the second set. These results concern researchers because many women use estrogen-only hormone replacement therapy to alleviate menopausal symptoms.
