Citrus juices

Citrus juices may cause heartburn symptoms when consumed. Citrus fruits, including oranges, grapefruits, lemons, limes, and pineapples, are often shown to cause heartburn symptoms in many people.

Orange and grapefruit juices are frequently blamed for causing GERD symptoms including heartburn. This is especially true if you consume citrus fruits first thing in the morning. Citrus fruits are quite acidic, and having too much acid in your stomach can cause heartburn symptoms. Think of these foods as fueling the fire. Avoid citrus fruit juice if you want to prevent heartburn. Furthermore, tomatoes are a major cause of heartburn due to their high acid content. Not only do you consume tomatoes in salads and sandwiches, but you also consume tomato sauce on pizza and pasta.
