Marielle:力量训练结合足够的蛋白质摄入对健康有益,包括改善脑功能和心血管健康,并延长寿命。过去人们认为需要从动物蛋白中获取蛋白质,但现在研究表明植物蛋白也能胜任。我不必像迪士尼的反派角色加斯顿那样每天吃五个鸡蛋,因为我们对蛋白质来源的理解正在改变,植物也能提供足够的蛋白质。 Will Stone:为了增长或维持肌肉,我们需要锻炼肌肉并摄入蛋白质来提供能量和促进生长。蛋白质的质量取决于其消化率和氨基酸组成。必需氨基酸是肌肉的组成部分,人体无法自行合成,必须从饮食等外部来源获取。某些必需氨基酸对肌肉生长至关重要,缺乏会阻碍肌肉生长。动物蛋白的氨基酸组成与人体骨骼肌相似,富含肌肉生长所需的必需氨基酸。植物蛋白也能提供所有必需氨基酸,但某些氨基酸的含量可能低于肉类。以往的研究发现,食用动物蛋白后肌肉蛋白质的合成效果优于植物蛋白,但现在研究表明,如果食用富含蛋白质且多样化的素食,可以获得与食用肉类相似的肌肉增长效果。不需要过分关注每种植物的氨基酸含量,只需确保饮食均衡即可。豆类、豆腐和藜麦是蛋白质含量较高的植物性食物,混合植物蛋白粉可以确保获得所有必需氨基酸。

Chapters
This chapter explores the role of protein in muscle building, highlighting the importance of amino acids and the concept of protein quality. It sets the stage for comparing plant and animal protein sources.
  • Protein is essential for muscle growth and maintenance.
  • Amino acids are the building blocks of muscles.
  • Essential amino acids must be obtained from the diet.

Shownotes Transcript

It's long been thought that eating protein from animals (eggs, meat, chicken, fish) can help you become stronger. But a new study out of the University of Illinois shows that plant protein is just as effective at building muscle. NPR health correspondent Will Stone explains how the science around plant protein is shifting.Learn more about sponsor message choices: podcastchoices.com/adchoices)NPR Privacy Policy)
