Research highlight:
Good gut bugs

. Since then, Glenn 鈥� now Professor of Food Microbiology at 色狗导航 鈥� has pioneered the development of evidence-based prebiotic products.

Professor Gibson and the team at Reading wanted to develop a prebiotic that beneficial gut bacteria could most readily use, so they harnessed the very tools used by these bacteria in nature. Using enzymes from a strain of Bifidobacterium bifidum, they processed lactose into prebiotic carbohydrates called galactooligosaccharides. The idea was that these bacterial-origin prebiotics would be the optimum fuel for good gut microbes.

, the prebiotic product markedly increased good gut bacteria compared to prebiotics manufactured using commercially-available enzymes (which often come from yeast).

Health benefits in clinical trials

The research group has since reported an impressive range of positive effects in trials of the product:

Taking discovery to market

In 2003 the prebiotic, Bimuno, was commercialised by the biotechnology company, Clasado 鈥� now an enterprise with around 50 employees and a cross-continental presence. Bimuno was used by Team GB to help avoid tummy upsets in Rio in 2016, and is recommended to prevent travellers鈥� diarrhoea by nutritionists working with international sporting stars. In the USA Bimuno is included as a branded ingredient in several supplements and nutraceuticals.

The customer testimonials impress, for instance:

鈥淏imuno powder has completely changed my life! 鈥� I now no longer have 'bloating' and abdominal discomfort, which worsened as the day went on. It's not until something like that disappears that you realise how bad it had been!鈥� Liz Abbott 鈥� reviewer on Trustpilot

鈥淎mazing product, helped with stomach pains, sleep, energy and regularity.鈥� Catrina Dakin 鈥� reviewer on Trustpilot

As our understanding of gut microbes develops, Professor Gibson believes that the role of prebiotics in wellness will increase. He is now investigating their potential impacts on cholesterol control, obesity and gut-brain interactions, including autism.

• Poor diet, stress, age and overuse of antibiotics deplete the beneficial microbes in our digestive system, with a variety of knock-on effects for our wellbeing
• Prebiotics are fuels for the good bacteria that are inside us, allowing them to grow and multiply. Prebiotics are unaffected by heat or the ravages of passing through our bodies, whereas probiotics (products that actually contain good bacteria) can be
• already estimated to be worth $3 billion worldwide
