Q. I have suffered with canker sores all my life. I’ve read in your column about sauerkraut but I’ve found kiwi fruit works better.
If you eat at least two kiwi fruit a day, the next morning the canker sore will be much smaller and less painful. It works best if you chew the fruit and swish it around in your mouth for as long as you can. The fruit needs to be very ripe to work. I hope this helps anyone that reads it.
A. We appreciate your experience. Other readers have also had success using kiwi fruit to fight canker sores (aphthous ulcers). Some people eat kiwi weekly to prevent outbreaks of these sores, which may occur after scratching or inadvertently biting the inside of the cheek or lip.
One visitor reminded us that some people are allergic to kiwi:
“My grandson had his mouth and lips swell painfully large from eating kiwi. His doctor said he should never again eat even the smallest piece of kiwi.”
Other remedies for canker sores include sauerkraut juice, instant iced tea powder or powdered alum on the sore spot. Many readers report that taking l-lysine acts to prevent canker sores; several endorse an old-fashioned remedy of swishing buttermilk around in the mouth to help heal canker sores quickly.
Several visitors also noted that canker sores could be a symptom of an underlying health problem, especially celiac disease. In this auto-immune disorder, gluten from wheat, barley or rye triggers the body to attack the digestive tract. AMJ suggested:
“Canker sores are one of the lesser known, non gastric, symptoms of celiac disease. This individual might consider asking her doctor for a screening panel, just to check this out.”
