This fibre is a non cellulose complex sugar (polysaccharide). As part of the fibre content of Noni juice it performs important functions within the gastrointestinal tract which have ramifications on the entire health of the body.

Pectin absorbs water and slows the emptying of the stomach contents into the small intestine. Because of this action and because it provides bulk in the gut it provides a feeling of fullness. Pectin also binds bile acids and cholesterol and regulates glucose absorption through the gut wall which is important for those with blood sugar conditions of any sort.

It has been shown that high fat diets, low in fibre, cause a build up of fecal bile acids. This situation may promote tumours within the bowel caused by colonic bacteria converting these acids to secondary bile acids. These particular acids then act as tumour promoters within the bowel. Pectin in the diet will increase the volume of material moving through the bowel, thereby reducing the concentration of faeces through the bowel, and the concentration of potentially carcinogenic substances in the bowel. Pectin will also speed the transit of the material through the bowel thus allowing a reduced time for fecal carcinogens and colonic bacteria to be in contact with the bowel wall. Pectin also alters colonic bacterial metabolism which aids in the reducing the production of carcinogens within the bowel.
