Prebiotic foods are those that contain non-digestible fibers that promote the growth of beneficial bacteria in the gut. Here are five examples of prebiotic foods that are often processed in industrial settings:
-
Inulin: Extracted from chicory root or other plants, inulin is often added to various processed foods and dietary supplements to enhance fiber content.
-
Fructooligosaccharides (FOS): Commonly derived from vegetables like onions, garlic, and bananas, FOS can be found in many functional foods and sweeteners that promote gut health.
-
Galactooligosaccharides (GOS): Often derived from lactose, GOS is used in infant formulas and other dairy products to support healthy gut flora.
-
Psyllium Husk: Though more commonly known as a laxative, psyllium is also a source of soluble fiber that can be found in various fiber supplements and foods designed for digestive health.
-
Resistant Starch: Found in processed foods such as some types of pasta, rice, and bread that have been modified to retain resistant starch content, which acts as a prebiotic fiber.
These ingredients are often included in processed foods, supplements, and functional products aimed at improving digestive health.
