Prebiotic fiber is fuel for your gut bacteria. You can find it in vegetables like asparagus and artichokes, or you can take it as a powder supplement. I recommend working up to about 20 grams per day.
Here are three benefits:
1. It feeds your good gut bacteria: Prebiotics are the food that your good gut bacteria eat so they can thrive.
2. It strengthens your immune system: By increasing the amount of good bacteria in your gut that fight off the bad ones.
3. It improves memory: The gut-brain axis is real. Studies show that prebiotic fiber supplementation may improve memory.
