Protein is having a major moment, showing up in everything from snack foods to coffee drinks—but do we actually need more of it? In this episode of Science Quickly, Rachel Feltman speaks with science journalist Bethany Brookshire about what has happened with the rise of the protein craze, how much protein people really need and why most of us are already getting plenty. They explore where the trend came from, what the science says about daily intake and how there are potential downsides to focusing too heavily on protein at the expense of overall diet and sustainability.
