Benefits of dietary fiber Although currently is very challenged by various researchers, the inclusion in the diet of foods rich in dietary fiber can prevent or alleviate various diseases such as: Constipation: The best known effect of fiber is its ability to facilitate defecation . The fiber increases stool bulk to create solid waste and absorb water, which produces bulky stools and less consistent. In addition, decreases intestinal transit time, ie the evacuation process accelerates, increasing its frequency. Therefore, adequate content of dietary fiber is essential to prevent and relieve constipation. , Diverticulosis or diverticular disease: disease characterized by the appearance of small pouches in the colon wall, finger-shaped glove called diverticula.The diverticulosis increases with age as in older people the intestinal wall is weaker and the pressure exerted within the colon facilitates the creation of the diverticula. Excessive pressure must exert muscular layer of the colon wall while trying to expel a stool with little volume increases the pressure inside the colon and may contribute to the development of diverticular disease. Today it is accepted that the diverticulosis is due to increased deposition of elastin in the walls of the colon and a loss of vagal innervation. Although it has been postulated that diverticulosis is associated with low-fiber diet food No scientific evidence supports its prevention by eating foods rich in dietary fiber. Obesity: Obesity is a disease that is associated with hypertension, ischemic heart disease, diabetes and many cancers.
