Prebiotics are food compounds that cannot be digested by the body. They stimulate the growth and activity of probiotics in the colon, thus benefiting health.
Although we find many foods enriched with prebiotics, there are foods with naturally-occurring prebiotics in them.
Some foods that contain prebiotics are:
- Artichokes, chicory, and bananas
- Legumes, potato, and sweet potato
- Garlic, onion, and leek
- Wheat, oats, and barley
Eating these foods consistently will positively impact your overall gut health, by increasing defenses against pathogens, decreasing the risk of intestinal infections, and preventing constipation due to their content of prebiotics that feeds the gut flora.
Prebiotics decrease the risk of intestinal infections
As you can see, it is not necessary to resort to expensive products enriched with prebiotics, as you have plenty of natural foods that contain them.
