The nurse should instruct the client to eat a low-fat, high-fiber diet, avoiding acidic foods. Tomatoes are highly acidic and consumption of tomatoes or tomato-based sauces can worsen the symptoms of GERD. Bananas are low in fat and acid and contain fiber. White bread does not contain acid and has fiber. Grilled salmon is a low-fat choice that avoids fried foods, which are high in fat and irritating to clients with GERD. Steel-cut oatmeal is a low-fat, high-fiber option.
