Studies indicate that the average American diet is deficient in fiber. This is critical because fiber is just as necessary as probiotics in maintaining a healthy bowel. Moreover, the colon is now considered to comprise 70% of the immune system! So the healthier your bowel is, the more effectively your body can fight and prevent disease. Without proper fiber, chronic constipation and/or various diseases may develop such as: diverticulitis, irritable bowel syndrome, appendicitis, selected bowel obstructions, as well as colorectal cancer; the 2nd most common type of cancer in America. A plant-based diet is mandatory for proper elimination. So remember, "It's better to have a royal flush than a full house!"
