In 2007, Rich Roll was diagnosed with a serious health condition called Ulcerative Colitis. This disease causes inflammation and ulcers in the lining of the large intestine and can be extremely painful. After trying various medications to treat his condition, Rich decided to make some major changes to his lifestyle in an effort to heal himself naturally. He began eating a plant-based diet and exercising regularly, and within months he was completely symptom-free. Since then, Rich has become a huge advocate for plant-based living and has written several books on the subject.
