Certain foods aggravate acid reflux, which occurs frequently when you have gastroesophageal reflux disease, known as GERD. Some acid reflux triggers may involve healthy foods, including fresh pineapple. However, pineapple contains an enzyme that aids digestion may protect you from acid reflux. Digestive difficulties sometimes promote GERD symptoms. Knowing your trigger foods allows you to reduce or avoid acid reflux. Pineapple may or may not worsen symptoms because people respond differently to foods.
Acid Reflux Causes
Experiencing acid reflux more than twice a week indicates GERD, according to the National Digestive Diseases Information Clearinghouse. Symptoms occur when stomach acid backs up into the esophagus, often causing heartburn, the burning sensation in your upper chest and throat. Sometimes you can taste bitter or sour contents in the back of your mouth. Heavy meals encourage acid reflux by slowing down digestion, requiring the stomach to secrete more acid.
Trigger Foods
Foods that trigger acid reflux relax an esophageal muscle. The muscle normally contracts after food enters the stomach to prevent acid backflow. When the muscle relaxes, it does not close tightly and allows acid reflux. Pineapple is often cited as a trigger because of its acidic content. The acid reflux diet from Jackson Siegelbaum Gastroenterology recommends avoiding pineapple and citrus fruits. Penn Medicine advises against pineapple in a diet to help manage heartburn. Other foods commonly mentioned as triggers include high-fat foods, fried foods, tomato-based products, chocolate, onions, garlic, caffeine and carbonated beverages.
Testing Pineapple
Because you may have your own specific triggers, you can carefully test fresh pineapple to see if it causes symptoms. Eat small amounts of pineapple or sip pineapple juice to find out the results. Avoid canned or frozen products, which may contain sugary or fatty ingredients that worsen acid reflux. To confirm whether pineapple causes or aggravates symptoms, take note of the foods you eat and your GERD symptoms for about a week. Your symptoms may result from other foods or ingredients in your meals rather than pineapple.
Pineapple Benefits
Pineapple may protect the digestive system because it contains high amounts of fiber and the enzyme bromelain. The enzyme helps break down proteins so the body can digest foods more efficiently, Natural News.com notes. Smoother digestion decreases the risk of acid reflux. Bromelain also contains anti-inflammatory properties to reduce inflammation and swelling. There is no known connection between fresh pineapple and reduction of acid reflux, but you can continue to enjoy the fruit if it doesn't result in symptoms.
