Foods that may act as natural colon cleansers and promote colon health include fruit, vegetables, oatmeal and bran, according to WebMD. Foods rich in soluble or insoluble fiber help with colorectal cancer, constipation, diverticular disease and other gastrointestinal problems.
Although the average American eats between 10 and 15 grams of fiber daily, 20 to 35 grams of fiber is ideal for colon health, notes WebMD. Drinking alcohol in moderation and drinking plenty of fluids promotes a healthy colon. Avoid red meat and tobacco whenever possible.
Other options for cleansing the colon include magnesium, herbal teas, enzymes and enemas, explains WebMD. Some people may use stimulant or nonstimulant laxatives to cleanse the colon. These products usually come in powder or liquid form, and they may be taken orally or inserted into the rectum. Because colon-cleansing products may have side effects, it is important to speak to a doctor before using them.
Another way to cleanse the colon is to have a colon irrigation done by a medical professional, states WebMD. Many people prefer a colon irrigation over an enema, which may be uncomfortable and produce an unpleasant odor. A colon irrigation uses significantly more water than an enema, using gravity to flush multiple gallons of water through the colon.
