As an increasing number of Americans across the political spectrum voice concerns about the health risks of ultra-processed foods, correspondent Bill Whitaker speaks with Health and Human Services secretary Robert F. Kennedy Jr. and former commissioner of the U.S. Food and Drug Administration Dr. David Kessler. Whitaker reports on a decades-old government classification for substances in our food and why Kennedy and Kessler are calling for change.

Eighty years after the end of World War II and liberation of the last remaining Nazi concentration camps, correspondent Lesley Stahl reports on the miraculous story of three pregnant women, and their babies, who survived notorious slave labor and concentration camps, including Auschwitz. Stahl meets the three “babies,” now 80 years old, who were born after their mothers concealed their pregnancies from their Nazi captors and gave birth under the most horrific conditions imaginable. The story of their survival, and how they found each other 65 years later, involves seemingly impossible twists of fate, luck and unfathomable suffering. Stahl also tells the tale of the American medic who was part of the liberation of the camps and discovered, and ultimately helped save, one of the babies.
