Tongue pain after eating fruit: causes and remedies

Nutritional deficiencies

Another common cause of tongue pain is vitamin B12 deficiency, according to the Cleveland Clinic. This nutrient supports neurological function and helps your body produce red blood cells.

Low levels of vitamin B12 can lead to canker sores, vision problems, depression and irritability. Another symptom is glossitis, a condition that causes a red, painful tongue, notes the National Health Service (NHS). Tenderness and swelling of the tongue are also common.

According to the NHS, glossitis can also be a symptom of iron deficiency, especially if it is accompanied by other symptoms like fatigue, shortness of breath, heart palpitations and pale skin.

Although these symptoms are not related to fruit consumption, certain fruits, especially those that are acidic, can make tongue pain worse.

Blood tests performed by your doctor can determine if you have a vitamin deficiency. Getting more B12 from foods like meat, dairy, and fish, and more iron from meats, legumes, and leafy greens, as well as supplementation, addresses these nutritional deficiencies.

In the meantime, to relieve a sore tongue, eliminate tart, acidic, and salty foods from your diet for about a week. Tomatoes, fruit juices and citrus fruits are very acidic, so eliminate them and see how your body reacts. If your symptoms persist, consult a healthcare professional to determine the cause and receive treatment.
