Meera Kaur, PhD, RD 26 Food Sources of Probiotics • • • Yogurt Fermented soy products Other fermented foods Meera Kaur, PhD, RD 27 How do Probiotics work? • Modify GI Ecology because of its ability to – – – – – survive the harsh travel condition of upper GI tract adhere to the epithelial of the intestine and colonize compete with the pathogenic microorganisms for nutrient and colonization sites secrete antibiotic-like substances called bacteriocins, and provide nutritional services via synthesis of vitamins Meera Kaur, PhD, RD 28 Why Probiotics?… • Research Suggests Probiotics Bacteria can – help reduce the risk of certain diarrhea, cancer, allergy, helicobacter pylori, UTIs – assist in managing lactose intolerance, IBD, hepatic encephalopathy, and – enhance the immune functions, overall health Meera Kaur, PhD, RD 29 Why Probiotics? • Probiotics, GI-tract Functionality and Human Health Cluster -- experiences and prospects Meera Kaur, PhD, RD 30 Nutrition Checklist... • Has there been a loss of more that 10% usual weight in the past 6 months? • For children and adolescents: Is growth slower than others of the same age? • Is the diet being limited in some way that may result in missing nutrients and energy? Meera Kaur, PhD, RD 31 Nutrition Checklist • • • • Is fibre being avoided? Are milk or milk products being avoided? Is a non-prescribed diet being followed? Are meals or snacks being skipped, or is food consumption less than usual? • Are caffeine, alcohol, sugar or fat being substituted for other foods? Meera Kaur, PhD, RD 32 Discussion Use of Synbiotics (probiotics+ plant fibre): Evidence of Significant Positive Outcome Topping (2007) : risk of bowel cancer and ulcerative colitis Bengmark (2006) : Pancreatitis, trauma immunoparalysis Bengmark (2005) : Critically ill unwanted pathogens (c. diff) Bengmark (2005) : Clinical Medicine reinforce immune system Rayes et al. (2005): Liver transplant bacterial infection rate Bengmark (2004) : ITU in septic morbidity Bengmark (2003) : Critically ill research limited, but great hope for future; confirmed for LAB Olah et al. (2002 ): Acute pancreatitis pancreatic sepsis, no. of surgical interventions Meera Kaur, PhD, RD My Mom 33 • 70 year old widow, vegetarian. Since last 8 months she is suffering from episodes of copious diarrhea followed by constipation. Increasingly developed resistance to antidiarrhal medications. She is Diabetic (NIDDM) +BP and on medications. Poor GI functions. Can not tolerate most of the foods especially vegetables and fruits (cooked or raw). Oral Intake is always poor. My brother phoned me describing her chronic illness and asked dietary advise. What I did? Discussed with her doctor. We put her on a synbiotic capsule (one/day) for 40 days. Then I suggested to add plain yogurt (1-2 tsp) in most of the foods that she eats (rice, lentil, milk, stew,soup etc). Did it work? Meera Kaur, PhD, RD 34 Implications for the Practitioners • Dietary fibre and probiotics (from natural sources such as yogurt) may be considered for the management of GI functions in health and diseases. • Whenever possible and applicable, LAB containing yogurt may be included in the diet of patients to improve liver function & to manage lactose intolerance, IBD and IBS.
