Mina Kim: 我观察到社交媒体上充斥着关于蛋白质的各种说法，许多网红鼓励人们摄入超过联邦建议量的蛋白质，并推销补充剂、人造蛋白质来源和大量红肉。我们正在讨论这种所谓的蛋白质热潮背后的驱动因素，以及如何评估个人的蛋白质需求。 Alice Callahan: 我注意到人们对蛋白质的兴趣显著增加，超过了对糖、纤维或钠的关注。美国人有一种过度关注单一营养素的历史，现在轮到蛋白质了，而社交媒体放大了这种趋势。食品工业也正在关注人们对蛋白质的需求，并据此调整产品，市场上充斥着高蛋白产品，这可能强化了人们对蛋白质的需求。由于缺乏权威指导，社交媒体影响者得以介入并提出不同的建议，导致人们困惑。 Christopher Gardner: 我认为联邦指南大致正确，但大多数人已经超过了这些指南。联邦指南旨在满足或超过97.5%人口的需求。蛋白质对身体至关重要，缺乏蛋白质会导致身体机能下降。身体没有储存蛋白质的地方，多余的蛋白质会被转化为碳水化合物。锻炼是肌肉建设的90%，蛋白质是10%。 Stuart Phillips: 我认为评估蛋白质需求的方法已经过时，需要更新。蛋白质对肌肉的益处只有在运动的背景下才显现出来。只有在需要构建新肌肉或儿童生长时，更多蛋白质才有帮助。蛋白质的信息已经被过度宣传。动植物蛋白之间的差异并不重要，只要摄入足够。我鼓励老年人多运动，并考虑蛋白质摄入，早餐是一天中最应该考虑蛋白质摄入的一餐。

Shownotes Transcript

“We’re in a protein craze, and it’s hard to ignore,” writes New York Times health reporter Alice Callahan. Social media feeds are inundated with claims about protein – encouraging protein-maxxing diets that contain many times the federal recommendations, and pushing supplements, artificial protein sources and lots of red meat. We’ll talk with Callahan and nutritionists about how to evaluate your own protein needs — and the risks of the online protein obsession.

Guests:

Alice Callahan, nutrition reporter, The New York Times

Christopher Gardner, nutrition scientist and professor of medicine, Stanford Prevention Research Center

Stuart Phillips, professor of kinesiology and nutrition researcher, McMaster University in Ontario, Canada
