16. Chocolate
Caffeine, like coffee, relaxes the LES in chocolate. Another acidic ingredient that might raise stomach acid is cocoa powder. When you consume chocolate, you release serotonin. Serotonin is a stress-relieving and mood-regulating hormone. Serotonin, on the other hand, might relax the LES, making acid reflux more likely. Chocolate contains acidic cocoa powder, which may exacerbate your symptoms. Cocoa can cause a spike of serotonin to be released from the intestine cells that relax the esophageal sphincter. Gastric contents can rise when this muscle relaxes. In the esophagus, this generates a burning sensation. Caffeine and theobromine, which are found in chocolate, can exacerbate symptoms.
