Guar gum is a low-viscosity water-soluble dietary fiber that has been used to treat diabetes because it slows the absorption of glucose from the gut. However, adverse effects such as regurgitation, obstipation, abdominal cramps, diarrhea, and itching are common (1). Partially hydrolysed guar gum has been added to enteral formulas and food products as a source of dietary fiber it can reduce laxative use, diarrhea in septic patients receiving total enteral nutrition, and symptoms of irritable bowel sjmdrome (2). 

The present review indicates that while pectin products continue to serve as a well-established food additive for technological purposes, the application of pectins for health benefits has many potential opportunities. In the last few decades, considerable research has been done on the physiological effects of pectin in humans as a water-soluble dietary fiber supplement. Some novel pharmacological activities of pectins and pectic polysaccharides are gaining more attention. Although most natural pectins from fruits and vegetables have not been shown to have these activities, chemical and enzymatic modifications may provide useful tools for producing such products for human health care.

Data have been presented emphasizing the variability of dietary fiber sources. Water holding capacity estimates differed by technique as well as source. The most Important advantage of the osmotic suction technique is that the measurement Includes the water soluble dietary fiber components. This is a more realistic model of the digestive tract. The human fecal batch in... 

The variation ia water solubiUty among polysaccharides results ia varied physiological roles. Plant ceU-waH polysaccharides and lignin provide iasoluble dietary fiber (IDF) nondigestible storage polysaccharides, some pectic polysaccharides, and most of the functional additives contribute soluble dietary fiber (SDF). 

Nutrient analysis of stabilized rice bran and its derivatives indicates that it is a good source of protein, dietary fiber and carbohydrates, in addition to several valuable phytonutrients, antioxidants, vitamins and minerals (Table 17.1). SRB and its water-soluble and water-insoluble derivatives contain all the nutrients at different levels. They are gluten and lactose free and do not give rise to any food allergy. 

Fruit dietary fiber is the product obtained by drying the washed wet pulp (the main by-product of juice industries) that remains after fruit juice extraction. Because fruit dietary fibers contain a high level of pectins as the major water-soluble fibers, they have similar technological functions as isolated pectins (Diepenmat-Wolters, 1993)...
