Sanjay Gupta: 我认为蛋白质对人体健康至关重要,它不仅仅是增肌的工具,还参与了包括激素和神经递质的合成、免疫系统的增强以及皮肤、头发和指甲的健康等多种生理过程。 然而,我注意到最近高蛋白饮食成为一种流行趋势,许多人为了追求所谓的健康而忽略了其他营养素的摄入。 我们需要对这种趋势保持谨慎的态度,并关注其潜在的风险。 Tim Spector: 我认为当前美国社会对蛋白质的关注是一种时尚,它被过度夸大了。 首先,大多数美国人已经摄入了足够的蛋白质,甚至超过了身体的需求。过量摄入蛋白质不仅不会带来额外的益处,反而可能导致其他营养素的缺乏,例如纤维素。 其次,这种对蛋白质的过度关注,导致人们忽视了其他营养素的摄入,例如水果、蔬菜和纤维。 此外,食品公司利用人们对健康的渴望,通过精妙的营销策略,将高蛋白零食等加工食品包装成健康食品,从而误导消费者。 低脂食品也是一个例子,它们通常经过高度加工,用糖类淀粉等代替脂肪,对健康有害。 关于种子油,目前没有足够的证据表明其对健康有害,不应妖魔化。 总而言之,我们应该采取一种更全面的营养观,避免妖魔化任何一种食物,并关注食物的多样性。
