Since the beginning of the 1990s, increasing evidence supports beneficial effects of nut consumption on health. A new analysis of the Spanish PREDIMED trial, published in BMC Medicine, has expanded our knowledge. The study showed that individuals eating nuts more than three times per week died less often from cardiovascular disease and cancer than non-consumers. The study also adds an important finding that previous epidemiological studies could not provide: a protective effect on premature mortality was only seen in the intervention group in which nut consumption increased during the 4.8 years of follow-up, not in the intervention group with additional olive oil consumption or in the control group. Nut consumption actually decreased during follow-up in the latter two groups. Questions remain to be answered on the quantity of nuts to be consumed for health benefits, on possible mechanisms of action, and on whether some types of nuts should be favored.Please see related research: http://www.biomedcentral.com/1741-7015/11/164.
自 20 世纪 90 年代初以来，越来越多的证据支持坚果摄入对健康有益。发表在《BMC 医学》上的对西班牙 PREDIMED 试验的一项新分析扩展了我们的知识。研究表明，每周食用坚果超过三次的人死于心血管疾病和癌症的几率低于非食用者。该研究还提供了一个以前的流行病学研究无法提供的重要发现：只有在干预组中，随着坚果摄入量在 4.8 年的随访期间增加，才会对过早死亡产生保护作用，而在额外摄入橄榄油的干预组或对照组中则没有。在后两组中，坚果的摄入量在随访期间实际上减少了。关于坚果摄入量对健康的益处、可能的作用机制以及是否应该优先选择某些类型的坚果等问题仍有待回答。请参阅相关研究：http://www.biomedcentral.com/1741-7015/11/164。
