Prebiotics
Some fibers, known as prebiotics, play an important role in nourishing beneficial gut bacteria and supporting the gut flora.
What are prebiotics?
Prebiotics are fermentable fibers. This means they are not digested in the small intestine but instead pass through to the large intestine, where they are “consumed” (fermented) by beneficial bacteria. These good gut bacteria use prebiotics as a food source, allowing them to grow. The growth of these bacteria can support the gut flora. Therefore, it is very important to consume enough prebiotics to support your digestive system and gut flora.
Beneficial gut bacteria produce beneficial substances through the fermentation process, such as acetate, propionate, and butyrate, also known as short-chain fatty acids. These substances can support normal bowel function and stool consistency. These bacteria are part of the gut flora (also known as the gut microbiome), a collective term for all the different bacteria, yeasts, and fungi in the large intestine. The types and amounts of these microorganisms vary from person to person, making each person’s gut flora unique, similar to a fingerprint.
Prebiotics in Food
Prebiotics naturally occur in the form of certain carbohydrates, such as fructans (fructo-oligosaccharides) and galactans (galacto-oligosaccharides). Foods rich in prebiotics include vegetables, fruits, legumes, and whole grains.
Prebiotic Supplements
It may not be feasible for everyone to consume enough prebiotics through diet alone. An easy way to increase your prebiotic intake is by using a prebiotic supplement. Well-known and scientifically researched prebiotic supplements include guar gum fibers, also known as Sunfiber or Partially Hydrolyzed Guar Gum (PHGG), psyllium fibers, and inulin (derived from fructo-oligosaccharides or FOS).
