I frequently check in at CalorieLab for up-to-date nutrition news.
Karen Collins, M.S., R.D., C.D.N., was a guest contributor there March 14, 2009, writing about the potential health benefits of nuts. I was aware of the cardiovascular benefits; she taught me about possible salutary effects on cancer and diabetes.
From my own literature review, the cardiac benefits are associated with a nut “dose” of three to five 1-ounce servings a week.
Last December, I blogged about reversal of metabolic syndrome with a Mediterranean Diet supplemented with nuts.
I recommend Ms. Collins’ article to you.
