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.
