An Inverse Association between Fruit and Vegetable Consumption and Mortality蔬菜水果摄入量和死亡率呈负相关

New evidence reveals a robust inverse association between fruit and vegetable consumption and all-cause, cancer and cardiovascular mortality, with benefits seen in up to 7+ portions daily. Cox regression analysis of the annual surveys of nationally representative random samples of the general population linked to mortality data (65 226 participants aged 35+ years in the 2001–2008 Health Surveys for England, median follow-up: 7.7 years). Consumption of vegetables was most protective, while frozen/canned fruit consumption was apparently associated with increased mortality. Standard serving sizes for vegetables and fruits are half a cup, except for greens (one cup).又有新证据表明水果蔬菜摄入量与各种原因，癌症和心血管病死亡率之间呈很强的负相关，每天摄入量可达7份以上均有益。对英格兰总人口有代表性的随机样本的年度调查（2001-2008年间共有65226名35岁以上参与者的英格兰健康调查，中位随访时间7.7年）Cox回归分析显示与死亡率数据有关。蔬菜摄入量最具保护性，而冷冻/罐装水果摄入量则与死亡率上升明显相关。标准份量的蔬菜和水果是半杯，除了青菜（1杯) 。
