Can eating green peppers cause an allergic reaction?

Whether eating bell peppers causes allergies varies from person to person. As a common vegetable, bell peppers contain abundant dietary fiber, capsaicin, vitamin C, and other nutrients. Under normal circumstances, consuming bell peppers does not cause allergic reactions. However, for individuals with certain special constitutions or weakened immune systems, components such as capsaicin in bell peppers might stimulate the immune system and trigger allergic reactions. These allergic reactions may manifest as symptoms including skin itching, redness, nausea, vomiting, diarrhea, dizziness, chest tightness, and difficulty breathing; in severe cases, anaphylactic shock may even occur. Therefore, individuals with allergic constitutions are advised to minimize consumption of bell peppers when the allergen is unclear and to seek timely medical attention if allergic symptoms occur, following the physician's recommendations for symptomatic treatment. Although bell peppers are nutritious, excessive consumption should be avoided to prevent adverse effects on health.
