Lecithin Component May Reduce Fatty Liver, Improve Insulin Sensitivity
ScienceDaily (May 25, 2011) -- A natural product called DLPC (dilauroyl phosphatidylcholine) increases sensitivity to insulin and reduces fatty liver in mice, leading Baylor College of Medicine researchers to believe it may provide a treatment for prediabetic patients. DLPC is an unusual phospholipid and a trace component of the dietary supplement lecithin. Dr. David D. Moore, professor of molecular and cellular biology at BCM, and his colleagues at first thought that DLPC would provide...

Chronic Estrogen Exposure Linked to High Blood Pressure
ScienceDaily (May 27, 2011) -- Researchers have found that long-term estrogen exposure generates excessive levels of a compound, superoxide, which causes stress in the body. The build-up of this compound occurs in an area of the brain that is crucial to regulating blood pressure, suggesting that chronic estrogen induces a build up of superoxide that in turn causes blood pressure to increase For many years doctors believed the estrogen women consumed in the...
