Recurrent oral ulceration, also known as canker sores describe a disorder where painful, small, oval to round, sores develop inside the mouth. Typically, they heal in a week or two, even if you don’t treat them, but because they occur in the mouth there are certain kinds of food that can exacerbate the condition and effectively, make the healing time longer.

Canker sores and low-acid foodsCanker sores and cold sores are often confused, but they are not the same condition. As a matter of fact cold sores are triggered by herpes simplex virus and they are very contagious. Characteristic signs of cold sores are collections of painful blisters that contain liquid which surface on the outside of the mouth, mostly around the border of the lips and nose. Canker sores, unlike colds sores, emerge only in the mouth, specifically on the soft tissues in the mouth including the inside of the lips, on the gums and on the tongue. They are round or oval, with a white to yellow middle, and a red edge. Tingling, as well burning sensation inside the mouth can be experienced couple of days before the sores develop.

Since this is a condition that only afflicts the inside of the mouth, there are particular foods that have been related to onset of cold sores and may in fact aggravate the condition, specifically acidic foods and citrus fruits and vegetables including apples, lemons, oranges, pineapples, strawberries, and even tomatoes. To reduce additional irritation and appearance of new sores you should avoid consuming these foods and drinking the juices that come from them. You should also avoid hot and spicy foods and foods that are too hard or crunchy. Eating those foods can only lengthen the healing process.

Canker sores and low-acid foodsSince acidic foods can cause quite a discomfort when dealing with mouth ulcers, you should add some low acidic foods to your everyday diet. Foods with low acidity levels include peas, beans, lentils, scrambled and fried eggs, soft cooked and shredded chicken and beef, mashed potatoes, peanut butter and custards and puddings and fruits such as melons, bananas, papayas, avocados, mangoes , pears and prunes. Scientists still do not know the exact cause of the ulcers, but certain factors such as allergies to certain types of food, shift in hormones and physical trauma inside the mouth like unintentional biting of the cheeks and tongue and using a toothbrush with hard bristles or toothpaste with foaming agents may trigger the onset.

Foods that are most likely to initiate an allergic onset of mouth ulcers consist of milk, dairy products like cheese, ice cream and buttermilk, all kinds of nuts, seeds, wheat and whole wheat food, cocoa and even coffee

If you think that might have a food allergy, set an appointment with your nutritionist or doctor so they can instruct you which allergy test you should get and can prescribe you a topical ointment, mouth rinse or some over-the-counter pain relief containing acetaminophen or ibuprofen. Besides pain relief, they also have properties which can reduce the inflammation.
