    Study Notes

    Prebiotics

    • Prebiotics are non-digestible fibers that promote the growth of beneficial bacteria in the gut.
    • They help improve digestion, boost immune function, and enhance overall gut health.

    Sources of Prebiotics

    • Inulin is a widely used prebiotic in processed foods, providing 25-35% energy compared to digestible carbohydrates.
    • Inulin is a versatile ingredient with health benefits, including increased mineral absorption and management of constipation.
    • Oligosaccharides are short chains of sugar molecules found in various foods, serving as prebiotics and supporting the growth of beneficial gut bacteria.
    • Resistant starch is a type of prebiotic that functions as a prebiotic, feeding beneficial gut bacteria.

    Probiotics

    • Probiotics are live microorganisms that provide health benefits when consumed in adequate amounts.
    • They support gut health, enhance immune function, and can improve digestion.

    Good Bacteria

    • Lactobacillus is a genus of gram-positive bacteria found in food such as yogurt, with applications in maintaining human well-being.
    • Lactococcus is a genus of bacteria commonly used in the dairy industry for fermented dairy products.
    • Streptococcus thermophilus is a widely used bacteria in the dairy industry, beneficial for lactose-intolerant individuals.
    • Propionibacterium is a genus of bacteria used in cheesemaking, creating CO2 bubbles.
    • Bifidobacterium is a genus of bacteria that make up the gastrointestinal tract microbiota in mammals.

    Health Benefits of Probiotics

    • Probiotics support gut health, enhance immune function, and can improve digestion.

    Synbiotics

    • Synbiotics are a combination of probiotics and prebiotics that work together to support gut health.
    • Examples of synbiotic combinations include yogurt with inulin, kefir with oats, and probiotic supplements with added prebiotics.

    Postbiotics

    • Postbiotics are bioactive compounds produced by probiotics during fermentation in the gut.
    • They include substances like short-chain fatty acids, peptides, and enzymes.
    • Postbiotics support gut health, enhance immune function, and have anti-inflammatory effects.
    • An example of a postbiotic is butyrate, a short-chain fatty acid produced by the fermentation of dietary fibers by gut bacteria.

    Prebiotics

    • Prebiotics are non-digestible fibers that promote the growth of beneficial bacteria in the gut.
    • They help improve digestion, boost immune function, and enhance overall gut health.

    Sources of Prebiotics

    • Inulin:
      • Widely used in processed foods as a fat or sugar replacer.
      • Provides only 25-35% energy compared to digestible carbohydrates.
      • Has a sweetness level of 10% of sucrose.
    • Oligosaccharides:
      • Short chains of sugar molecules found in various foods.
      • Serve as prebiotics, supporting the growth of beneficial gut bacteria.
    • Resistant Starch:
      • A type of resistant starch that functions as a prebiotic, feeding beneficial gut bacteria.
      • Example: cooked and cooled potatoes.

    Probiotics

    • Probiotics are live microorganisms that provide health benefits when consumed in adequate amounts.
    • They support gut health, enhance immune function, and can improve digestion.

    Good Bacteria

    • Lactobacillus:
      • A genus of gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria.
      • Found in food such as yogurt, and has diverse applications in maintaining human well-being.
    • Lactococcus:
      • Commonly used in the dairy industry for the manufacture of fermented dairy products.
      • Can be used in single-strain starter cultures or mixed-strain cultures with other lactic acid bacteria.
    • Streptococcus Thermophilus:
      • Widely used in the dairy industry.
      • Considered a safer bacterium than many other Streptococcus species.
      • Helps people who are lactose-intolerant to digest dairy products.
    • Propionibacterium:
      • A gram-positive, anaerobic, rod-shaped genus of bacteria.
      • Used in cheesemaking to create CO2 bubbles.
    • Bifidobacterium:
      • A genus of gram-positive, nonmotile, often branched anaerobic bacteria.
      • Ubiquitous inhabitants of the gastrointestinal tract.

    Health Benefits of Probiotics

    • Support gut health
    • Enhance immune function
    • Improve digestion

    Synbiotics

    • A combination of probiotics and prebiotics that work together to support gut health.
    • Examples: yogurt with inulin, kefir with oats, probiotic supplements with added prebiotics.
    • Enhance the survival and activity of beneficial microorganisms in the digestive system.

    Postbiotics

    • Bioactive compounds produced by probiotics during fermentation in the gut.
    • Examples: short-chain fatty acids, peptides, and enzymes.
    • Support gut health, enhance immune function, and have anti-inflammatory effects.
    • Offer the benefits of probiotics without the need for live bacteria.
    • Example: butyrate, a short-chain fatty acid produced by the fermentation of dietary fibers by gut bacteria.
