Why does consumption of resistant starch lead to increased butyrate production in the colon, while simple sugars do not?

A)Amylase inhibits butyrate formation directly
B)Glucose directly represses bacterial fermentation
C)Simple sugars bypass colonic microbiome
D)Microbiota ferment resistant starch into butyrate

💡 Explanation

Resistant starch reaches the colon undigested, where the gut microbiota ferments it, producing short-chain fatty acids like butyrate. This process does not occur with simple sugars because they are absorbed in the small intestine; therefore, resistant starch fosters butyrate production in the colon, rather than simple sugars which are absorbed earlier.
