Dietary fiber is an element of plant cell walls in the food that can't be digested by the enzymes in the digestive tract. Based on its chemical properties, dietary fiber is divided into soluble and insoluble. Included in the group of insoluble fibers are lignin, cellulose, and hemicellulose.
Carrots, wheat, and fruits the seeds are edible such as strawberries are sources of lignin. Relatively high cellulose foodstuffs are including wheat flour, peas, root vegetables, apples, and fruits containing seeds. Meanwhile, high hemicellulose foods include bran, cereals, and oatmeal.
In the colon, cellulose, hemicellulose, and lignin absorb water so that the volume of stool becomes larger. They also shorten the time between the entry of food and the issuance of feces. As a result, the contact between the irritating substances with large intestine becomes short to prevent the occurrence of disease in the colon and rectum.

Food sources of soluble fiber include apples, oranges, bran, oats, seaweed, beans and legumes, soybean kinds, red and green beans, and snow peas.

Tempeh, for example, aside from being a source of soluble and insoluble fiber, is also a source of monounsaturated fatty acids that can lower blood cholesterol. In addition, tempeh also contains isoflavones which, of late, associated with its function to lower the risk of osteoporosis.
