Avoid foods that trigger acid reflux. Limit foods with high acidity like citrus (oranges, lemons, limes) and tomato (pizza sauce). Don't eat spicy foods (salsa, tacos, and burritos) and foods high in fat. Don't drink caffeine (soda, coffee, tea, chocolate) and alcohol. Write down the foods you eat and your body's reaction in a food journal to indentify and track trigger foods. Eating small meals is better for your sensitive stomach.
