The study included 18 prospective studies which found that peanut (5 studies) and tree nut (3 studies) intake were similarly associated with reduced mortality risks. The study suggested that nut consumption was associated with a reduced all-cause and cause-specific mortality, with the strongest reduction for coronary heart disease (CHD) mortality. Both tree nuts and peanuts may lower mortality and the benefits may be achieved with a low level of nut consumption.
