Scarlata echoed this research, sharing, "Garlic is rich in fructans, a well-known prebiotic fiber. Fructans promote the abundance of key health-promoting microbes such as Bifidobacterium, Lactobacillus and Faecalibacterium prausnitzii.

prausnitzii is one of the most abundant bacteria, or probiotics, in a healthy gut microbiome. It's been shown to be low or depleted in several intestinal disorders such as inflammatory bowel disease. Fructan intake from foods like garlic, bananas and artichokes, Scarlata shares, is associated with improving the intestinal barrier a protective gut layer that keeps intestinal contents in the gut versus permeating into the bloodstream , improved laxation and better cholesterol and blood sugar regulation.

Ehsani shares, "Inulin can help grow beneficial gut bacteria in the microbiome. It also assists in having easier-to-pass bowel movements, meaning less straining or pushing is required.

A study published in Current Developments in Nutrition explored the function of the eight main prebiotic sources commonly found in the literature and while only time will tell if it remains in the top three, inulin continues to demonstrate one of the most widespread researched prebiotic benefits thanks to its fermentation in the gut.

Vibrant and beautiful, kiwifruit is a great addition to help increase your prebiotic intake. Scarlata shares, "Kiwifruit is rich in polyphenols, plant chemicals that have been shown to have prebiotic activity, in turn boosting the health-promoting gut flora.

Foods from this category contain a type of prebiotic known as galacto-oligosaccharides. If you experience flatulence after consumption of these foods, you're not alone. Scarlata shares, "The well-known intestinal gas effects post bean consumption is simply a reminder that our gut flora are fermenting the prebiotic fiber in the beans, providing key health benefits along the way, such as increasing health-promoting bacteria, such as Bifidobacteria.

From these, they analysed the prebiotic content of types of food. Read more:. How postbiotics could boost your health and even help reverse ageing.
