• Eating More Tree Nuts Lowers The Risk of All-cause Death by up to 20 Percent

  • Here's the Nutty Truth!  Whether it's an actual tree nut or a peanut, nuts in general have several very important health benefits. Nuts have long been called heart-healthy, and the study is the largest ever done on whether eating them affects mortality.

    The benefits were seen from peanuts as well as from pistachios, almonds, walnuts and other tree nuts. The researchers did not look at how the nuts were prepared — oiled or salted, raw or roasted.

    A bonus: Nut eaters stayed slimmer.

    Eating tree nuts daily resulted in a nearly 30 percent reduction in heart disease deaths

    To conduct this research, scientists examined an immense cohort from two large, well documented, long-running studies including 76,464 women from the Nurses' Health Study conducted between 1980 and 2010, and the Health Professionals' Follow-up Study including data on 42,498 men from 1986 to 2010. Participants in the studies filled out detailed food questionnaires every two to four years. With each food questionnaire, participants were asked to estimate how often they consumed nuts in a serving size of one ounce.

    Researchers found that individuals who ate a serving of tree nuts less than once a week had a 7 percent reduction in mortality (tree nuts included walnuts, hazelnuts, almonds, Brazil nuts, cashews, macadamias, pecans, cashews, pistachios and pine nuts). Those consuming a serving once a week experienced an 11 percent reduction; two to four times per week, a 13 percent reduction; five to six times per week, a 15 percent reduction; and seven or more times a week, a 20 percent reduction in death rate.

    Risk reductions were seen across a number of potentially fatal chronic illnesses, including cancer, heart disease, stroke and diabetes, as the scientists attributed lower death rates to an improvement in cholesterol ratios and reductions in oxidative stress, inflammation, adiposity and insulin resistance. The lead study author, Dr. Charles Fuchs, concluded, “The most obvious benefit was a reduction of 29 percent in deaths from heart disease, the major killer of people in America. But we also saw a significant reduction, 11 percent, in the risk of dying from cancer.”
