Life expectancy in the U.S. has always been different for people of color. And since the pandemic, that gap has widened. In her new book, Under the Skin, journalist Linda Villarosa uncovers the hidden toll of racism in America and how racial disparities impact all aspects of healthcare. In an interview with Karen Grisby Bates on the podcast Code Switch, Villarosa talks about the biases that lead to worse care for communities of color and how medical students are pushing against them.
