Some foods don’t just lack fiber but may interact with our gut flora to contribute to disease in other ways. Check out my last video Microbiome: The Inside Story (http://nutritionfacts.org/video/microbiome-the-inside-story).

This amazing prebiotic story helps explain why fiber-rich (i.e. whole plant) foods are so good for us. See, for example, Dr. Burkitt’s F-Word Diet (http://nutritionfacts.org/video/dr-burkitts-f-word-diet/). This reminds me of The Broccoli Receptor: Our First Line of Defense (http://nutritionfacts.org/video/the-broccoli-receptor-our-first-line-of-defense-2/), in terms of our body using what we eat as cues to optimize immune function.

Have a question for Dr. Greger about this video? Leave it in the comment section at http://nutritionfacts.org/video/prebiotics-tending-our-inner-garden and he'll try to answer it!
