The health of your entire body depends of your colon as well. The colon is vital for your digestive system, your immune system and also balances the amounts of water in your body. The colon is the part of the large intestine from the cecum to the rectum. Toxic substances will remain in your body if your colon is not functioning properly since the waste could not be removed from the body. That same waste is absorbed by the colon’s walls and ends in the blood. Healthy food and healthy colon transit the food through the body in 24 hours. However, when eating processed food, that contains no nutrients and fibers, the transit lasts for 70 hours. These foods and the slow transit allow 30 pounds of toxic substances to accumulate into your colon and body in general.
