Pantothenic acid is hyperacidity. Stomach acid can help digestion, but if too much stomach acid will hurt the stomach, duodenum, or even "burn" the mucous membranes and muscles, causing diseases such as gastric ulcer or duodenal ulcer. When you eat more acidic foods, such as plums, vinegar, etc., it will stimulate the secretion of gastric acid, and then the gastric acid will penetrate the damaged gastric mucosa (ulcer), which will stimulate the stomach and cause pain.
