Prebiotics and Probiotics
This document discusses prebiotics and probiotics. It defines prebiotics as non-digestible fibers that support beneficial gut bacteria, and probiotics as live microorganisms that provide health benefits. Some key points covered include: the health benefits of prebiotics like promoting probiotic growth and enhancing immune function; examples of probiotic foods like yogurt and fermented soy products; the criteria a microbe must meet to be considered a probiotic; and the mechanisms by which probiotics provide benefits like interacting with the immune system and competing with pathogens. The roles of prebiotics and probiotics in oral health are discussed, as well as their safety, dosages, and synergistic effects when combined as synbiotics.

- 3. MICROBES AND HUMAN BEINGS Microbesare best known for their role in causing disease in humans. In the 19th century, men lost their fear of Gods and instead acquired a fear of microbes. But Colonic Bacteria plays an important role in maintaining health and also in treatment of childhood diarrhea and post – antibiotic diarrhea.

- 8. PREBIOTICS • Non –digestible but fermentable food ingredients – Fructo-oligosaccharides (chicory, inulin) – Lactulose • Positively affect the endogenous flora by changing the composition and activity of the intestinal microbiota • Stimulate the growth of one or a limited number of bacterial species with prospect to promote the health of the host – FOS Bifidobacterium – Lactulose Lactobacilli
- 11. Health benefits ofPrebiotics promotion of growth of probiotics increase of calcium absorption direct effects on the host: • stimulation of IL-10 and interferon γ, • enhancement of IgA secretion, • modulation of inflammatory responses to pathogens The oligosaccharide derivatives contain sugars that are specific epithelial cell receptors to which pathogens adhere and they, therefore, provide „decoy” adhesion sites and cause pathogens to adhere to luminal contents rather than to epithelial cells.

Probiotics are definedas living micro-organisms, principally bacteria, that are safe for human consumption and, when ingested in sufficient quantities, have beneficial effects on human health, beyond basic nutrition. (World Health Organization / Food and Agriculture Organization of the United Nation) Probiotics : Greek meaning – “For Life” Probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. Gaurner et.al - 2005

- 16. A Successful PROBIOTIC must… 1.It should capable of exerting a beneficial effect on the host animal, e.g. increased growth or resistance to disease. 2. It should be of human origin. 3. It should have high cell viability. 4. It should be non-pathogenic and non-toxic. 5. It should be able to interact or to send signals to immune cells. 6. It should have capacity to influence local metabolic activity. 7. It should be stable and capable of remaining viable for periods under storage.
- 17. MECHANISM OF ACTION 1.Direct interaction : Probiotics interact directly with the disease-causing microbes, making it harder for them to cause the disease. 2. Competitive exclusion : Beneficial microbes directly compete with the disease developing microbes for nutrition or enterocyte adhesion sites. 3. Modulation of host immune response : Probiotics interact with and strengthen the immune system and help prevent disease.

SAFETY AND ADVERSE EFFECTS •Mild side effects, if occur. • Digestive – bloating and flatulence • Infections in Immunocompromised patients and Not recommended in critically ill person • Diabetic patient to be cautious because of high level of sugar in probiotic drinks • Constipation and Increased Thirst – associated with S. boulardii • Consumption of a mixture of six probiotic bacteria increased the death rate of patients with predicted severe acute pancreatitis. • Prebiotic – Oligosaccharide Abdominal Discomfort and Distension + significant levels of flatulence
- 28. DOSAGE • Minimum Consumption= 100 g of a probiotic food of 107 cfu/gram • Over the counter dose = 1-10 billion cfu/dose • Recommended dosage = 5 grams a day • The Nutrition Information center of South Africa’s University of Stellenbosch recommended that daily consumption of prebiotics be held below 20 grams.
