Fructooligosaccharides (FOS) are a type of prebiotic fibre naturally found in various plant sources, such as fruits, vegetables, and grains. FOS provide several beneficial effects for human health as a dietary fibre.1Tandon D, Haque MM, Gote M, Jain M, Bhaduri A, Dubey AK, Mande SS.

Here are five key roles of fructooligosaccharides (FOS):
- Gut health: FOS are a food source for beneficial gut bacteria, stimulating their growth and promoting a healthy gut microbiome.
- Digestive support: FOS help maintain regular bowel movements, supporting regularity and promoting a healthy digestive system.
- Enhanced nutrient absorption: FOS support the absorption of certain minerals such as calcium and magnesium.
- Immune system modulation: FOS have the potential to regulate immune responses, supporting healthy immune function.
- Reduced risk of colon disorders: FOS promote the production of short-chain fatty acids that have been associated with a reduced risk of colon disorders.
What gut bacteria are involved in breaking down/fermenting fructooligosaccharides (FOS)?
Bifidobacterium, Lactobacillus, Ruminococcus, and Faecalibacterium species are among the beneficial bacteria known to be involved in the fermentation of fructooligosaccharides (FOS) in the gut, breaking them down into beneficial byproducts such as short-chain fatty acids like butyrate and acetate.6Wang, S., Xiao, Y., Tian, F., Zhao, J., Zhang, H., Zhai, Q., Chen, W. (2020). Rational use of prebiotics for gut microbiota alterations: Specific bacterial phylotypes and related mechanisms. Journal of Functional Foods. 66. 103838. 10.1016/j.jff.2020.103838.
How can you get more fructooligosaccharides (FOS) in your diet?
OurComplete Prebioticprovides a good source of fructooligosaccharides (FOS). Other rich sources of fructooligosaccharides (FOS) include onions, garlic, leeks, asparagus, and whole grains. Also, ripe bananas, especially when they have brown spots, are a great source of FOS. By incorporating these foods into your diet, you can naturally increase your intake of fructooligosaccharides (FOS) and support a healthy gut microbiome.
Where to find your fructooligosaccharide (FOS) score in the Chuckling Goat Gut Microbiome Test
The Chuckling Goat Gut Microbiome Test features your FOS score in the prebiotics report. Guidance on how to work with your FOS score will be featured in your personal action plan. Please note that this information is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your GP or another qualified health provider if you have any questions about the impact of FOS on your health.
