Gastric health guide: Prebiotics
Prebiotics are compounds that support the growth of beneficial gut bacteria by providing essential nutrients, primarily in the form of polysaccharides and oligosaccharides.
- These substances help increase populations of bacteria like bifidobacteria and lactobacilli, which play a key role in the fermentation process within the colon.
- Prebiotics also help lower stomach pH, creating an environment that suppresses harmful microorganisms..
- At the systemic level, they contribute to various health benefits, such as reducing cholesterol, triglycerides, and phospholipids, enhancing mineral absorption, and regulating blood glucose levels.
- Additionally, they strengthen intestinal defenses against infections and promote digestive regularity.
- However, excessive intake can lead to diarrhea or stomach discomfort due to their laxative effect.
Types of Prebiotics:
- Inulin – A dietary fiber
- Oligofructose – Derived from the enzymatic hydrolysis of inulin
- Pectic substances
- Galacto-oligosaccharides (GOS)
- Fructo-oligosaccharides (FOS)
Effectiveness Factors:
Type of Oligosaccharide: While the recommended average dose to enhance bifidobacteria growth is 15g/day, specific types may vary in efficacy.
Individual Gut Microbiota: The pre-existing levels of bifidobacteria play a crucial role. In adults, as little as 3g/day may be sufficient, making a microbiota assessment advisable before supplementation.
