What happens to the health of our colones within just two weeks after switching from a

standard American diet to one centered around plants?

Watch the video to find out.

We have 100 trillion microorganisms residing in our gut, give or take a few trillion,

0:25.2

but the spread of the Western lifestyle has been accompanied by microbial changes,

0:30.5

which may be contributing to our epidemics of chronic disease.

0:34.2

The problem is that we're eating these meat-sweet diets characterized by a high

0:39.1

intake of animal products and sugars, processed foods, and a low intake of whole plant foods.

Contrary to the fermentation of the carbohydrates that make it down to our colon, the fiber

0:50.7

and resistance starts that benefit us through the generation of those magical short-chain

0:54.8

fatty acids like butyrate, microbial protein fermentation. When excess protein is consumed,

1:02.2

that generates potentially toxic and pro-carcinogenic metabolize involved in colorectal cancer.

1:08.6

And so what we eat can cause an imbalance in our gut microbiome and potentially create a recipe for colorectal cancer. And so what we eat can cause an imbalance in our gut microbiome

and potentially create a recipe for colorectal cancer,

1:15.7

where a high-fat, high-meat, high-processed food diet

1:19.3

tips the scale towards dysbiosis and colorectal cancer,

1:23.9

whereas a high fiber and starch, lower meat diet

1:26.8

can pull you back into symbiosis

1:29.1

with your friendly flora and away from cancer.

1:33.1

We now have evidence from interventional studies suggesting that adopting a plant-based,

minimally processed high-fiber diet may rapidly reverse the effects of meat-based diets

on the gut microbiome.
