Fructo-oligosaccharides are a type of carbohydrate that the human body cannot digest.
Found in bananas, onions, garlic, and asparagus, FOS serve as food for beneficial gut bacteria (probiotics), promoting a healthy digestive system.
Occurrence:
FOS naturally occur in a variety of plants and vegetables, including bananas, onions, chicory root, garlic, asparagus, jicama, and leeks.
They can also be synthesized commercially and are often added to foods as a prebiotic supplement.
Chemical Nature:
Fructo-oligosaccharides are short-chain fructose molecules linked together by glycosidic bonds.
They are classified as oligosaccharides, which are carbohydrates made up of a small number of monosaccharide (simple sugar) units.
Because human digestive enzymes cannot break down FOS, they reach the colon intact, where they serve as food for beneficial bacteria.
Medicinal Benefits:
1. Gut Health:
FOS support the growth of beneficial gut bacteria, particularly Bifidobacteria and Lactobacillus, enhancing the health and balance of the gut microbiome.
2. Digestive Aid:
By promoting healthy bacteria, they help improve digestion and can prevent or reduce the occurrence of constipation.
3. Immune System Support:
A healthy gut microbiome supported by FOS can enhance immune function and reduce the risk of infections.
4. Blood Sugar Management:
FOS may help regulate blood sugar levels by improving insulin sensitivity and decreasing the absorption of glucose.
