Blue Zones | Longevity

Dr. @Dr. William Li gets it! 👏 Thanks for spreading the word about one of the original blue zones’ most powerful foods. Until about 1970, nearly 70% of the calories consumed by Okinawans came from purple sweet potatoes. And Okinawa went on to become home to one of the longest-lived populations in the world. Coincidence? We don’t think so. 🍠 #bluezones #okinawa #longevity #purplesweetpotato
