Soy: Soybeans, soy nuts and edamame, plus any products made from soy (like tofu, soymilk, etc.) can help to reduce the production of new cholesterol. A little can go a long way—aim for about 25 grams of soy protein a day (the amount in a cup of edamame). And those who are at an increased risk of breast or prostate cancer may want to skip it since too much of soy’s phyto-estrogens can act similarly to the body’s own estrogen (which has been shown to feed some hormone-dependent tumors).
