Not for nothing, but scientific study has also found that a diet high in nuts is associated with a 20% reduction in death risk by any cause! The robust study followed 71,764 people in the southern United States and 134,265 people in China, these divided by gender.
All three groups of daily nut eaters (Americans, Chinese men, and Chinese women) experienced a lower risk of total mortality as well as death by cardiovascular disease. Though the study did not control for other lifestyle factors, the results are still highly encouraging.
