Study reveals daily nut consumption reduces death rate.

nut picturesA new study has revealed that it’s not only an apple a day that keeps the doctor away. The largest study of its kind reveals that daily nut consumption lowers mortality rate. The results were not confined to a particular nut and the reduction in mortality was similar both for peanuts and for “tree nuts” — , hazelnuts, almonds, Brazil nuts, cashews, macadamias, pecans, cashews, pistachios and pine nuts.

The research released by the Dana-Farber Cancer Institute, Brigham and Women’s Hospital, and the was published in the New England Journal of Medicine. Regular nut-eaters were also found to be more slender than those who didn’t eat nuts. The study examined the effects of nut consumption of 76,464 women between 1980 and 2010, and 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.

“The most obvious benefit was a reduction of 29 percent in deaths from heart disease — the major killer of people in America,” said Charles S. Fuchs, MD, MPH, director of the Gastrointestinal at Dana-Farber, who is the senior author of the report. “But we also saw a significant reduction — 11 percent — in the of dying from cancer,” added Fuchs, who is also affiliated with the Channing Division of Network Medicine at Brigham and Women’s.

“In all these analyses, the more nuts people ate, the less likely they were to die over the 30-year follow-up period,” explained Ying Bao, MD, ScD, of Brigham and Women’s Hospital, first author of the report. Those who ate nuts less than once a week had a seven percent reduction in mortality; once a week, 11 percent reduction; two to four times per week, 13 percent reduction; five to six times per week, 15 percent reduction, and seven or more times a week, a 20 percent reduction in death rate.
