Quotes:

Dr. Richa Mittal

“As you add fiber in your diet, it’s important to not go from 5g a day to 40. But actually, work your way up, and that way your gut bacteria have a chance to acclimate, and you’re actually gonna change your gut bacteria to the ones that handle it.”

“Our bacteria and our gut eat what we eat.”

Dr. Avishkar Sabharwal

“People don’t realize that we’re more microbiome than we are human. We have more microbiota in our gut than actual human body cells.”

“You really need to incorporate more plant-based foods to meet your fiber requirements for the day.”

“It’s not really about counting the amount of grams that you’re eating; it’s just really about transitioning to more natural foods which will automatically increase the amount of fiber intake.”
