Anahad O'Connor:长期以来,人们就相信饮食与健康和寿命有关。历史上曾出现过许多饮食理论,但其有效性常常缺乏科学依据,许多饮食专家自己也可能早逝。目前流行的各种饮食方法(生酮饮食、素食、旧石器饮食、间歇性禁食、低卡路里饮食等)以及避免超加工食品的概念,其有效性和科学依据都值得商榷。营养科学研究很难进行,因为饮食习惯复杂且难以控制,长期追踪研究的难度极大。许多饮食方法之所以看起来有效,是因为它们与标准美国饮食相比有所改善。他个人提倡均衡饮食,避免超加工食品,多吃全谷物、蛋白质、不饱和脂肪和益生菌食物。“蓝区”的概念虽然影响广泛,但其说法存在争议,主要质疑其证据不足且夸大其词。 Saul Justin Newman:对“蓝区”理论的研究发现其数据存在严重问题,包括记录不准确、甚至存在欺诈行为,且“蓝区”居民的生活方式与该理论宣传的并不相符。所有“蓝区”的研究都存在类似问题,其宣传的健康生活方式与实际情况不符,因此不应将其作为健康饮食的参考。延长寿命的关键在于不吸烟和运动,而饮食方面研究结论混乱,难以得出明确结论。
