← Life Sciences & MedicineIf the large intestine's transit time decreases significantly, which consequence follows regarding short-chain fatty acid (SCFA) production?
A)SCFA production universally increases
B)SCFA production becomes more efficient
C)SCFA production will likely decrease✓
D)SCFA profiles remain unchanged overall
💡 Explanation
SCFA production decreases because the reduced transit time limits the fermentation of dietary fibers by the gut microbiome, therefore fewer SCFAs are synthesized. The decreased transit time causes incomplete digestion, rather than other outcomes where longer transit allows more fermentation.
