What are prebiotics and why are they important?

Understanding prebiotics

Prebiotics such as fructo-oligosaccharides (FOS) are an important component of a healthy diet as they promote the growth and/or function of the beneficial bacteria found in the colon.1 The colon is home to the largest mass of microbial life in the human body.2 In healthy people, these microbes live in harmony and play an important role in the digestive and immune systems.3–5 A large component of this biomass is composed of bacteria.2,6 These bacteria survive by feeding on the nutrients you eat and help to break down otherwise indigestible foods.3,4 However, imbalance of these bacterial populations can occur due to poor dietary habits, use of antibiotic medications and infection.7 Imbalances in bacterial populations have been implicated in many diseases including irritable bowel disease, arthritis, obesity, and mental illnesses.7,8 As such, it is important to maintain a healthy and balanced diet to promote the growth and survival of beneficial bacteria within the gut.

While there are no daily intake recommendations regarding dietary fibre, it has been suggested that as little as 4 g of FOS daily is sufficient to boost the population of beneficial gut bacteria.*9,10 As such, prebiotics play an important yet indirect role in the maintenance of gut and immune health.

*Overconsumption of FOS (>20 g per day) and other dietary fibres has been associated with side effects including diarrhoea, gas, bloating and stomach cramps.8

Natural sources of dietary fibre

Getting your daily FOS can be tricky but a little can go a long way. Natural sources of FOS include blue agave, yacon root, garlic, onion, leek, chicory root, Jerusalem artichoke, asparagus and banana.

Many of these foods can be difficult to obtain and aren’t the most appealing options to incorporate into your diet. Oral supplementation products such as Ensure Powder can be a convenient way of boosting your daily dietary intake of FOS and improving your gut health.11
