What are the health benefits of coarse plant foods?

Plant foods contain fiber. It is an insoluble polysaccharide. Fiber is not involved in digestion, is not affected by enzymes, and is not digested. But as it travels through the digestive tract, the coarse fiber picks up harmful unwanted toxins and flushes them out. It improves digestion, as it absorbs water and increases the volume of the food lump. Therefore, regular consumption of fiber and food that contains it is the prevention of constipation. Fiber is rich in bran, for example, wheat, as well as apples, pears, peaches.
