As has been mentioned on this blog before, plain unsalted nuts are very good for you. Dr. Stephen Devries, a preventative cardiologist at Northwestern Memorial Hospital in Chicago suggests we can rein in our cholesterol by sprinkling unsalted nuts on salad, yogurt, oatmeal, etc. Dr. Devries stated, "Nuts are rich in plant sterols, natural substances that block absorption of cholesterol from the digestive tract." Two handfuls a day - that's about 2 ounces - have been shown in studies to reduce "bad" cholesterol by 10 points. Dr. Devries says almonds and walnuts are the most beneficial.
