A systematic review and meta-analysis concluded that nut intake was associated with reduced risk of cardiovascular disease, total cancer and all-cause mortality, and possibly mortality from respiratory disease, diabetes, and infections. The analysis included 20 prospective studies (29 publications published up to July 19, 2016). The summary relative risks per 28 grams/day increase in nut intake was for coronary heart disease 0.71, stroke 0.93, cardiovascular disease 0.79, total cancer 0.85, all-cause mortality 0.78, and for mortality from respiratory disease 0.48, diabetes 0.61, neurodegenerative disease 0.65, infectious disease 0.25, and kidney disease 0.27. The results were similar for tree nuts and peanuts. There was evidence of a nonlinear association, with most of the reduction in risk observed up to an intake of approximately 15–20 grams (a handful) per day for most of the outcomes.

一项系统综述和荟萃分析得出结论，坚果摄入量与心血管病，癌症和全因死亡率，以及可能与呼吸系统疾病，糖尿病和感染的死亡率降低有关。 分析包括20个前瞻性研究（29篇文献发表截至2016年7月19日）。 坚果摄入增加28克/天的总体相对风险分别为，冠心病0.71，中风0.93，心血管病0.79，癌症0.85，全因死亡率0.78，以及呼吸系统疾病死亡率0.48，糖尿病0.61，神经退行性疾病 0.65，传染病0.25，肾病0.27。 树坚果和花生的结果类似。 有证据表明为非线性相关，对上述大多数预后，所观察到的大部分风险减少至大约每天摄入15-20克（一把）。 来源：http://bmcmedicine.biomedcentral.com/
