The vital role fiber plays in our nutritional process has only recently been recognized yet it is one of the most important deficiencies in the normal American diet.

Many authorities believe diets low in fiber are responsible for most, if not all, disorders involving digestion and elimination. Such problems as constipation, diarrhea, hiatal hernia, colitis, gallstones, appendicitis, hemorrhoids, varicose veins and diabetes, to name just a few, could be largely avoided by eating a daily diet high in fiber. These and other complaints of modern western man are virtually unknown in those parts of the world where fiber plays a major role in the local diet.
