Probiotics: contain beneficial bacteria (e.g., lactobacilli and bifidobacteria) that can help to reinforce the normal gut microflora which essentially contribute to the maintenance of an optimum microflora balance conducive to good health. Note! Probiotics are found in yogurt and other cultured milk foods and available as supplements in form of capsules, tablets, or powder.
Fiber: Plant foods are excellent sources of fiber, a nutrient that is especially important in digestion. Fiber comes in two forms - soluble and insoluble. Experts recommend eating a well-balanced high fiber diet. Unfortunately, Americans typically consume 10 to 15 grams of fiber a day, even though experts recommend 20 to 35 grams daily. Thus the need for fiber supplements such as oat bran (which increases the bulk of stool and softens stool) or glucomannan (which absorbs and binds components within the bowel movement). Some fiber-like natural substances known as prebiotics (e.g., inulin and fructo-oligosaccharides) serve as fuel for naturally occurring beneficial bacteria. Prebiotics and probiotics are sometimes combined in a supplement for adequate reinforcement of beneficial bacterial.
