Does chilli pepper speed up the rate of digestion in stomach?

The answer: no

Explanations:

Capsaicin, the compound that gives chili peppers their spicy flavor, can actually slow down digestion in the stomach. This is because capsaicin stimulates the release of cholecystokinin (CCK), a hormone that slows gastric emptying and increases the feeling of fullness. Additionally, capsaicin can irritate the lining of the stomach and cause inflammation, which can further slow down digestion.
