Foods to Avoid
Acidic fruits such as lime, lemon, tomato, strawberry, figs and apple worsen the symptoms of canker sore by irritating the ulcer in the mouth. By aggravating the canker sore symptoms, acidic fruits slow down healing of canker sores. To reduce discomfort, all types of acidic foods should be eliminated from the diet until the ulcers are cured completely. However, these acidic fruits are rich sources of ascorbic acid or vitamin C, a nutrient essential for maintaining the functions of the immune system. A weak immune system slows the speed of recovery. To meet your vitamin C requirement, you can take vitamin C supplements.
