Increasing dietary fiber does not consistently increase alpha diversity or improve gut health, and removing fiber does not decrease alpha diversity.

“removing fiber doesn't decrease the alpha diversity of the gut and there are other interventional papers in which they give people more fruits and vegetables and the alpha diversity doesn't go up either”

“there are interventional studies i have talked about in the past showing that adding fiber does not increase alpha diversity removing fiber does not decrease alpha diversity and there's another study that i'll show you right now interventional study another study showing adding fiber does not increase alpha diversity”

“as i will show you there are interventional studies where fiber is increased in someone's diet and there is no change in alpha diversity the gut doesn't get any healthier”

“When we do interventional studies with fiber, what we find is that giving humans more fiber doesn't change the alpha diversity of the human gut meaning doesn't create more diversity in the gut.”

“It's just another one to illustrate the fact that plant-based fiber doesn't give you a very diverse gut. And removing fiber doesn't decrease the diversity of your gut.”

“when we do Interventional studies with fiber what we find is giving humans more fiber doesn't change the alpha diversity of the human gut meaning doesn't create more diversity in the gut”

“plant foods have not been shown to do that fiber does not do that”
