University of Harvard -affiliated Dana-Farber Cancer Institute and Brigham and Women’s Hospital, and the Harvard School of Public Health scientists conducted the largest study of its kind .According to the scientists People who ate a handful of nuts daily were 20 percent less likely to die from any cause over a 30 year period than those who didn’t consume nuts
This Great study gives us another very valuable and important information is that the people who eat nuts regularly were found to be more slender than those who didn’t eat nuts.This finding helps to alleviate a great fear that is eating a lot of nuts will lead to overweight.
Major benefit of this long research is that nut consumption help to reduce 29 percent of deaths from heart diseases,one of the major killer of people in America and other countries.in addition to the heart diseases reduction rate it also helps to reduce the risk of dying from Cancer also.
But very important point is that which type or types of nuts were crucial to the protective effect could not be determined.However, the reduction in mortality was similar both for peanuts (a legume, or ground nut) and for tree nuts — walnuts, hazelnuts, almonds, Brazil nuts, cashews, macadamias, pecans, pistachios, and pine nuts.
This is a large study previously some small studies shows that an increase of nuts in the diet to lower the total mortality in specific populations.but this is really something big and very detailed one it shows the various levels of nut consumption and their effect on overall mortality in a large population and also it followed for more than 30 years this is may be the first study to follow such a long time for this type of evidences.several other studies show that nut consumption reduces the risk of diseases such as heart disease, type 2 diabetes, colon cancer, gallstones, and diverticulitis. Higher nut consumption also has been linked to reductions in cholesterol levels, oxidative stress, inflammation, adiposity, and insulin resistance.but not so detail and meaningful like this study.
For this study researchers collects information from two well-known, ongoing observational studies that collect data on diet and other lifestyle factors and various health outcomes. The Nurses’ Health Study provided data on 76,464 women between 1980 and 2010, and the Health Professionals’ Follow-Up Study yielded data on 42,498 men from 1986 to 2010.From alla these analysis the more nuts people ate, the less likely they were to die over the 30-year follow-up period,” explained Ying Bao of Brigham and Women’s Hospital, first author of the report. Those who ate nuts less than once a week had a 7 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 the death rate.
