1% prebiotic fiber by weight. The cheapest and most widely available prebiotic source. They don’t have the highest content of FOS compared to the other foods on this list, but they are definitely the most convenient and a great addition to a smoothie.
3. Raw Dandelion Greens
24.3% prebiotic fiber by weight. A rich source of prebiotics, and a great addition to salads or perhaps in a super prebiotic smoothie with a banana.
