    3. Probiotic case You have just recommended probiotics for one of your patients, based on Dr. Pietzak’s lecture. The patient’s mother asks if there’s anything she can do to help the probiotics work better. Is there?

    4. YES- Prebiotics Prebiotics are non-digestible food ingredients, such as non-digested short chain sugars and fiber that promote the growth of healthy bacteria in the intestines Examples: beta glucan, arabinoxylan, oligosaccharides (galacto- and fructo-oligosaccharides, FOS/GOS, inulin) Core symptoms are in 3 areas of hyperactivity, inattention, and impulsivity The most commonly-diagnosed behavioral disorder in children estimates of prevalence 3-11% However, prevalence may rise with the use of DSM-IV criteria, since it better characterizes the heterogeneity of ADHD in terms of its 3 subtypes: inattentive, hyperactive-impulsive, and combined. Wolraich study in school-children K-5 in Tennessee county: ADHD all types: 16.1% (6.8% if impairment considered) ADHD inattentive type 8.8% (3.2%) ADHD hyperactive/impulsive type 2.6% (.06%) ADHD combined 4.7% (2.9%) Increasing recognition of ADHD as a chronic condition persisting into adulthood and requiring long-term therapy on-going monitoring periodic assessment for consequences and complications Core symptoms are in 3 areas of hyperactivity, inattention, and impulsivity The most commonly-diagnosed behavioral disorder in children estimates of prevalence 3-11% However, prevalence may rise with the use of DSM-IV criteria, since it better characterizes the heterogeneity of ADHD in terms of its 3 subtypes: inattentive, hyperactive-impulsive, and combined. Wolraich study in school-children K-5 in Tennessee county: ADHD all types: 16.1% (6.8% if impairment considered) ADHD inattentive type 8.8% (3.2%) ADHD hyperactive/impulsive type 2.6% (.06%) ADHD combined 4.7% (2.9%) Increasing recognition of ADHD as a chronic condition persisting into adulthood and requiring long-term therapy on-going monitoring periodic assessment for consequences and complications

    5. Prebiotics - Benefits Increased numbers of healthy bacteria (Lactobacillus, Bifidobacter) Increased short chain fatty acids such as butyrate, which suppresses growth of unhealthy gut bacteria and provide energy to gut muscoal cells Increased absorption of calcium and magnesium Decreased gut inflammation Mixed results on glucose, cholesterol, triglycerides

    6. Prebiotics: Sources, Side effects: Sources: breastmilk, barley, bran and whole grains, legumes, such as beans; vegetables such as leeks, onions, asparagus, greens such as chicory, spinach, burdock, fruits such as bananas, berries Doses: 1 – 2 grams daily (adults) Side effects: flatulence, diarrhea, allergies
