Fried, greasy, and fatty foods can all cause heartburn and lead to reflux because they prevent the lower esophageal sphincter from fully tightening; this creates an opening for stomach acids to flow upward. Greasy, heavier foods are also harder to digest; so the stomach empties more slowly, which can trigger heartburn.
Does cooking vegetables reduce acidity?
Foods fall into either acid or alkaline categories. A food measures as acid when the pH ranges from zero to 6.9, neutral at 7 and alkaline or basic at 7.1 or 14.0. Most fruits and vegetables fall in the alkaline category, but release acid when heat gets applied in cooking.
