The Carters are encouraging everyone to go vegan. Yes, they really are! Beyoncé & Jay-Z wrote an introduction for a new book, called – The Greenprint: Plant-Based Diet, Best Body, Better World by author Marco Borges.

They revealed they changed up the way they eat after the birth of their twins in 2017, when they started focusing more on their health. So, are you going to give it a try?
