Doctor Explains Why Your Mouth Itches After Eating Pineapple

Oral Allergy Syndrome: Why Your Pineapple Might Be Stinging Your Mouth Millions suffer from oral allergy syndrome, a condition causing burning and itching after eating certain fruits. Dr. Rubin, a board-certified allergist, explains the science behind this common issue. "If you experience burning or stinging after eating pineapples or kiwis," he says, "it might be oral allergy syndrome." This condition occurs because the immune system mistakenly identifies proteins in these fruits as similar to those found in pollen. For those with pollen allergies, this can trigger a reaction. The good news is that cooking the fruits often helps. Heat alters the protein structure, preventing the reaction. Dr. Rubin also points out specific enzymes, bromelain in pineapples and actinidin in kiwis, as contributors. Modifying the pH, perhaps by adding salt or consuming with milk, can also help neutralize these enzymes. While the syndrome can be persistent, Dr. Rubin reassures viewers that it's often manageable. He advises consulting an allergist if other symptoms like swelling or breathing difficulties occur. The video offers a practical and reassuring explanation of a common allergy concern.
