Avoiding or limiting acidic foods like grapefruit juice and other citrus products may prevent the complications of gastroesophageal reflux disease, or GERD. However, reactions to citrus juices can vary from one person to another. Before you eliminate grapefruit juice or other nutritious foods from your diet, track your body's responses to determine whether citrus fruits trigger your acid reflux. If you are able to drink grapefruit juice without experiencing heartburn, indigestion or other GERD symptoms, you may benefit from the vitamins, minerals and other nutrients in this citrus fruit. Consult your doctor to develop a healthy eating plan that minimizes the symptoms and complications of GERD.
Significance
Occasional heartburn after drinking grapefruit juice, orange juice or coffee or eating spicy foods is not uncommon in the general population. If you are using over-the-counter antacids two or more times a week to treat heartburn, you may have GERD, a condition that causes chronic back-flow of acid from your stomach into your esophagus, or food tube. In normal digestion, a muscular ring called the lower esophageal sphincter, or LES, controls the opening between your stomach and your esophagus, preventing the stomach contents from rising into the esophagus. In GERD, the LES either opens at the wrong times or does not close completely, allowing digestive acids to flow upward. The presence of these acids causes the fiery sensation known as heartburn. If chronic acid reflux is left untreated, the presence of acid in your esophagus may damage the delicate lining, creating scar tissue that narrows the tube and promoting cellular changes that may lead to esophageal cancer.
Acidic Foods
The primary treatment goals for GERD include preventing acid reflux in order to minimize damage to the tissues that line the esophagus, according to the American College of Gastroenterology. Grapefruit juice and other citrus fruits contain citric acid, which may aggravate GERD symptoms and irritate the esophageal lining. Pineapples and tomatoes are also high in acid and may aggravate inflamed esophageal tissues. Limiting your consumption of these fruits and vegetables or their juices may reduce the acid content of your stomach contents and prevent esophageal damage when reflux occurs.
Clinical Studies
In a review of clinical literature published in the May 8, 2006 issue of the "Archives of Internal Medicine," Dr. Tonya Kaltenbach and colleagues analyze studies of the effects of lifestyle modifications on GERD. Kaltenbach and her co-authors evaluate the results of widely recommended dietary changes to determine which these measures can effectively relieve GERD symptoms and improve the acid balance in the esophagus. Researchers found that although grapefruit juice worsened heartburn in many patients with GERD, clinical research has not confirmed whether eliminating citrus fruits from your diet is an effective measure for preventing GERD complications. In case-control studies, elevating the head of your bed at night, sleeping on your left side and losing weight did improve GERD symptoms in some patients, Kaltenbach and her co-authors report.
Health Benefits
More clinical research is needed to determine whether avoiding grapefruit juice and other acidic foods has a positive effect on GERD. In a diet designed for GERD patients, Jackson-Siegelbaum Gastroenterology notes that your consumption of grapefruit and other citrus fruits should be based on your ability to tolerate these foods. Grapefruit juice provides essential nutrients, such as vitamin C, folate and potassium. Pink grapefruit contains beta-carotene, the precursor to vitamin A. Apples, berries, bananas, pears and other low-acid fruits recommended fruits on the Jackson-Siegelbaum GERD diet, provide these nutrients without causing acid reflux. Work closely with your doctor or dietitian to choose foods that meet your nutritional requirements without aggravating your GERD symptoms.
