Which of the following foods is known to decrease lower esophageal sphincter (LES) pressure?

Chocolate is known to decrease lower esophageal sphincter (LES) pressure due to its content of certain compounds. It contains methylxanthines, like theobromine and caffeine, which can relax the smooth muscle of the LES. This relaxation can lead to an increased risk of acid reflux and gastroesophageal reflux disease (GERD) symptoms because the LES plays a crucial role in maintaining the barrier between the stomach and the esophagus.

Other foods, such as vegetables, whole grains, and lean proteins, generally do not have the same effect on LES pressure. In fact, some of these foods can help promote overall gastrointestinal health and may even support proper functioning of the LES. This is why chocolate stands out as the correct choice in reducing LES pressure.
