Personalization for fiber supplements necessary?

Despite the type of supplement taken, people who consume a lot of fiber show the least changes in their microbiomes. This is according to research from US-based Duke University, which recently investigated if it is necessary to “personalize” fiber supplements to different people in light of the wide range of supplements on the market. Previously, different fermentable fibers have been shown to have different effects on the production of short-chain fatty acids depending on the individual. The research analyzed inulin, dextrin (Benefiber), and galactooligosaccharides (GOS) sold under the brand name Bimuno. NutritionInsight spoke with experts from Sensus who note that fibers work differently.

“Prebiotics are special dietary fibers that feed the good bacteria growing in the digestive system. These types of fiber provide nutrients to the bacteria, supporting health benefits to the digestive and immune systems. Prebiotics, like inulin, can be found in, for example, bananas, asparagus and flaxseed,” says Jolanda Vermulst, manager of market intelligence at Sensus.

“However, when our diets don’t contain enough of these sources, supplements are another way to add to this type of diversity,” Vermulst adds.
