Why does consuming large quantities of poorly digestible plant fiber lead to increased gas production and bloating in the digestive tract?

💡 Explanation

Undigested fiber reaches the colon, where gut microbiota ferments it, producing gases like methane and hydrogen, leading to bloating; because this fermentation process acts on undigested fiber, therefore excess fiber causes increased gas, rather than primarily stimulating enzyme secretion or peristalsis directly.
