A 14-day experiment involving a swap between 20 African-Americans and 20 Africans has been conducted by researchers from the University of Pittsburgh. And what were they swapping? Their diets.
The American participants got lucky and had to eat a low-fat, high-fiber diet consisting mainly of grains and beans, while the African participants were asked to eat a high-fat, high-sugar and low-fiber junk diet consisting of burgers and fries.
After only 14 days, the Americans had less bowel inflammation while the gut health of the African volunteers deteriorated markedly.
There were significant changes to cells lining the gut as well as gut bacteria – with the U. S volunteers showing marked improvements and less biomarkers for colorectal cancer.
Clearly then alterations in the microbiome can happen rapidly, damaging or protecting your colon – exactly as I told you in my book ‘The Secret Source of Your Good Health’.
