Why does tryptophan always get accused of making everyone sleepy after Thanksgiving? Today's Flashcards Friday takes a closer look at the real science behind this famous amino acid , including how it works in the body, why carbohydrates change everything, and how tryptophan connects to your mood and even your sense of gratitude. Whether your plate had turkey or tofu, this tiny molecule has a much bigger story to tell.

Three Things You'll Learn in This Episode: The Tryptophan Edition

  1. How tryptophan actually enters the brain and why the carb-insulin ratio determines whether it succeeds.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
