National Green Juice Day is observed worldwide every January 26, encouraging individuals to adhere to their New Year’s resolutions for healthier living. Established by Evolution Fresh in 2016, the day promotes the consumption of green juice, a drink that originated in Japan in the 1940s when army doctor Niro Endo began extracting juices from vegetable leaves to enhance his family's diet. Green juice gained popularity in Japan during the 1980s and has since evolved, with American versions incorporating a variety of green vegetables and fruits. On this day, people are encouraged to enjoy green juice, whether by purchasing it from stores, visiting juice bars, or making their own at home. Participants can also share their experiences on social media using the hashtags #NationalGreenJuiceDay and #GreenJuiceDay.
