The idea that zinc...

ΩDiets high in fish oil have a beneficial effect in patients at riskScientists today agree that there are five molecules that are known to affect or cause Alzheimer's disease, which plagues an estimated five million Americans.

A follow-up study, from the same research team at Children's Hospital Boston, now reveals exactly how omega-3's provide protection, and provides reassurance that widely used COX-inhibiting drugs like aspirin and NSAIDs don't negate their benefit. The findings,...

ΩI try not to let reports like this discourage me: (And I keep taking statins and Vitamin D):Why Almost Everything You Hear About Medicine Is WrongIn just the last two months, two pillars of preventive medicine fell. A major study concluded there’s no good evidence that statins (drugs like Lipitor and Crestor) help people with no history of heart disease. The study was based on an evaluation of 14 individual trials with 34,272...

ΩA perplexing medical paradox now has an explanation according to research undertaken at Barts and The London School of Medicine and Dentistry and published in the current issue of the Public Library of Science. The paradox is that taking folic acid, a B vitamin, lowers homocysteine in the blood which, epidemiological evidence indicates, should lower the risk of heart attack, but clinical trials of folic acid have not shown the...

Ω Loneliness is no fun — and now it appears it's bad for you as well. UCLA researchers report that chronically lonely people may be at higher risk for certain types of inflammatory disease because their feelings of social isolation trigger the activity of pro-inflammatory immune cells.In their analysis of 93 older adults, the researchers screened for gene function among different types of immune cells and found that genes originating...
