- Soy isoflavones demonstrate effectiveness in treating hot flashes
Isoflavones derived from soy may help cut the frequency and severity of hot flashes, according to a meta-analysis of more than a dozen clinical trials. The isoflavones appeared to reduce severity of hot flashes by 26% and frequency by 21%. Genistein supplements "were more than twice as potent at reducing hot flash frequency," researchers said.

- Study suggests trans fats may spur aggressive behavior
A study of 945 adults in PLoS One indicated that trans-fat intake might be linked to irritability, impatience and aggression, according to U.S.-based researchers. "We need to keep in mind that food labels tend to not differentiate between manufactured and natural trans fats. These are chemically different, and research is needed to clarify the roles of each type on behavior," said Dr. Karen Davison, who was not part of the research. Medscape (free registration)

Animals and GM feed
Animals fed a diet of genetically modified (GM) feed show no adverse health effects, according to a meta-analysis published in Food and Chemical Toxicology. Researchers examined 24 studies on the effects of diets containing GM maize (corn), potato, soybean, rice, or triticale on animal health. "Many parameters have been examined using biochemical analyses, histological examination of specific organs, hematology and the detection of transgenic DNA," the researchers write. "Results from all the 24 studies do not suggest any health hazards and, in general, there were no statistically significant differences within parameters observed."

Aspirin may counteract trans fat-related stroke risk
Older women whose diets include a substantial amount of trans fats are more likely than their counterparts to suffer an ischemic stroke, a new study shows. However, the risk of stroke associated with trans fat intake was lower among women taking aspirin, according to the findings from researchers at the University of North Carolina at Chapel Hill (USA). The study of 87,025 generally healthy postmenopausal women aged 50 to 79 found that those whose diets contained the largest amounts of trans fats were 39% more likely to have an ischemic stroke (clots in vessels supplying blood to the brain) than women who ate the least amount of trans fat. The risk was even more pronounced among nonusers of aspirin: Those who ate the most trans fat were 66% more likely to have an ischemic stroke than females who ate the least trans fat. The study appears in Annals of Neurology.
