Critical Condition: Health in Black America | Preview

Black Americans are nearly twice as likely to have high blood pressure, diabetes, and heart disease than White Americans, and their life expectancy is about five years shorter. Why?

In this special feature-length documentary, Oscar-nominated filmmaker Stanley Nelson investigates the dramatic health disparities in the US, even as scientists confirm that there are no meaningful genetic differences between races. From the deep history of pseudoscientific beliefs about race that still permeate modern medicine, to the latest research on how experiencing discrimination can directly damage human cells, Critical Condition explores the factors behind the health crisis facing Black Americans.
