研究者对4676例哈佛护士健康研究女性受试者的营养数据进行了评估，并确定膳食习惯最接近地中海饮食的女性端粒较长。端粒缩短与预期寿命较短以及癌症和心脏病风险升高相关，地中海饮食则可延缓端粒缩短。蔬菜、鱼和红酒等地中海饮食成分富含抗氧化剂并可防止细胞老化，但无证据显示任何单一食物更具优势。

纽约大学Nestle教授表示，由于该研究显示的女性膳食与端粒长度相关性并不能证明膳食可改变端粒，因此对其结果应审慎解读。总体而言健康膳食对人类有益，并有可能延长寿命。

知识链接：何为地中海饮食？

在对于世界各地肥胖情况的调查中，人们发现在地中海地区国家如希腊、意大利、西班牙，其居民摄入膳食脂肪的总量与美国人不相上下，但其心血管疾病的发病率却比美国人低很多。这是为什么呢？除了体育锻炼和阳光之外，最重要的一点是该地区居民具有与众不同的饮食习惯。这种特殊的饮食结构强调多吃蔬菜、水果、鱼、海鲜、豆类、坚果类食物，其次才是谷类，并且烹饪时要用植物油来代替动物油，尤其提倡用橄榄油，同时还摄入适量的红酒和大蒜等香辛植物。于是营养学家提出了“地中海饮食”的概念。地中海饮食不仅强调三大营养要素的均衡，更强调其来源是健康的。（背景资料来源于果壳网）
