If you suffer from them, here is a tip I saw in our local newspaper yesterday. Never heard of sauerkraut helping with them either. As for me, I'd much prefer eating kiwis!
Q: I have suffered with canker sores all my life. I've read in your column about sauerkraut, but I've found that 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 who reads it.
A: We appreciate your experience. Other readers also have had success using kiwi fruit to fight canker sores (aphthous ulcers). Some eat kiwi weekly to prevent outbreaks.
