Association of Nut Consumption with Total and Cause-Specific Mortality | Heart and Vascular Health |

Nuts are nutrient-dense foods that are rich in unsaturated fatty acids, fiber, vitamins, minerals, & many other bioactive substances, such as phenolic antioxidants and phytosterols. Observational studies & clinical trials have suggested that nut consumption has beneficial effects on coronary heart disease and its intermediate biomarkers (e.g., blood cholesterol). FDA concluded in 2003 that for most nuts, consumption of 43 g (1.5 oz) per day, as part of a low-fat diet, “may reduce the risk of heart disease.” More recently, a randomized primary-prevention trial involving persons at high cardiovascular risk showed a significant reduction in major cardiovascular events among participants assigned to a Mediterranean diet — one component of which was supplementation with walnuts, hazelnuts, or almonds — as compared with a control diet.
