So, will a high-fiber diet keep your colon clean? To put it simply, it will because dietary fiber is known for absorbing moisture, bulking up your stool, diluting the concentration of intestinal residues, and reducing the time of carcinogens touching the intestinal mucosa. In other words, eating high-fiber foods are good for promoting colon health and, more importantly, reducing the risk of colon cancer.
As you may know, the final step of clearing the waster of your body occurs in your colon or large intestine, where the stools form, move to the rectum, and them leave your body. That’s where dietary fiber comes in because it has a direct impact on the formation of stools.
Studies have found that the main culprit for colon cancer is poor eating habits, such as high-fat diet and lack of fiber intake. This disease usually occurs after the age of 40 and is more common in men. Early detection of colon cancer symptoms is a very positive thing to the treatment and prognosis. However, because most patients have no obvious symptoms in the early stage, many of them are misdiagnosed or never diagnosed. So, natural colon cleansing is incredibly important here. Apparently, a high-fiber diet is a viable way to fight colorectal cancer.
Dietary fiber can be divided into two types – the soluble and the non-soluble. On the one hand, cell walls of the former one contain water-soluble pectin and gums. On the other hand, cell walls of the latter contain cellulose, hemicellulose and lignin, which are not soluble in water. Due to the different structures, their impacts on the colon health vary. Even so, both of them play an important role in the health of the punctuation mark. Of course, the roles are different. The non-soluble one helps form stools that are soft and pass easily by absorbing water while the soluble one is the nutrition source of beneficial intestinal bacteria.
It has long been noted that high fiber diets can help reduce the risk of bowel cancer. A study found that daily intake of 35g or more cellulose could reduce the incidence of colon cancer by 40%. The incidence rate of African black population is very low. When scientists did the research they discovered that it might be closely related to their foods rich in fiber, such as corn and vegetables. Further studies found that a lack of fiber in diet could reduce the amount of stools and slow intestinal motility, which thus lead to the higher concentration of carcinogenic substances in the intestine, prolonged acting time of carcinogens on the intestinal mucosa, and rectal cancer.
So, a good diet containing more vegetables, fruits, and cellulose can help clean out the punctuation mark and reduce the risk of related problems. Studies have shown that vitamin A, C, E could help normalize the hyperplastic colonic epithelium. However, current data does not support the use of antioxidant vitamins for the prevention of colorectal cancer. And the nutrients that can suppress tumor formation include thioether found in in garlic, onions, leeks, and onions, terpenes in citrus, plant phenols in grapes, strawberries, and apples, and carotene in carrots, yams, and watermelon. It is worth mentioning that studies have shown that garlic has the strongest protective effect so that it can protect your distal colon from cancer.
In a word, high-fiber diet can cleanse the colon by keeping your stool soft and easy to manage. By doing so, it can prevent constipation, hemorrhoids, irritable bowel syndrome and other diseases. But health experts advise people not to use it as the only way to prevent colorectal cancer as currently there is not enough evidence to show that it works for it.
