It is up to our colon to eliminate the bulk of the most toxic and putrid waste from our bodies. When we obtsin energy from the food we eat, we creat a waste product (feces) that should be eliminated within 24 hours or less. But if your consuming a diet high in fat, meat-based, low fiber, the average American has a trtansmit time of 72-90 hours, meaning this waste begins a toxic build up that creates numerous problems for the colon and everyother part of the body. This is one good reason for so many people becoming ill. We must lower our fat intake, increase our fiber and strive to eat a more vegetarin diet.
