bowel movements

The form, frequency, and transit time of bowel movements may play an important role in colon health. Larger bowel movements rid the body of excess estrogen. A minimum of 200 grams of fecal output (about a half pound) per day is the goal for cancer prevention. Fiber from whole foods can prevent diverticulosis and constipation, while eating meat and processed foods may increase one’s risk for conditions such as diverticulosis. Foods high in antioxidants may also help increase stool size, whereas fat blocking drugs and certain fish can cause anal leakage. The health bacteria in our colon may even help us control our weight, so it’s important to keep our got flora happy.
