I found out quite by accident WALNUTS get rid of [canker sores] quite quickly. The first sign of an ulcer I chew walnuts and leave the paste in my mouth for a little while (30 seconds or so).
The first time was by accident, my ulcers disappeared so quickly I knew it had to be something I ate. And the only thing I had eaten differently the past day was walnuts.
Flaxseed oil and walnuts differ in lots of ways but both are high in omega-3. My gums got much better around the time I started taking flaxseed oil. I neither noticed nor expected this; my dentist pointed it out. Several others have told me the same thing. Tyler Cowen’s gums got dramatically better. One reader started and stopped and restarted flaxseed oil, making it blindingly clear that the gum improvement is caused by flaxseed oil. There is plenty of reason to think the human diet was once much higher in omega-3. All this together convinces me that omega-3 can both prevent and cure canker sores. Not only that, I’m also convinced that canker sores are a sign of omega-3 deficiency. You shouldn’t just get rid of them with walnuts; you should change your diet. Omega-3 has other benefits (better brain function, less inflammation, probably others).
Let’s say I’m right about this — canker sores really are prevented and cured by omega-3. Then there are several things to notice.
1. Web facilitation. It was made possible by the internet. My initial interest in flaxseed oil came from reading the Shangri-La Diet forums. I didn’t have to read a single book about the Aquatic Ape theory; I could learn enough online. Tyler Cowen’s experience was in his blog. Eric Vlemmix contacted me by email. No special website was involved.
2. Value of self-experimentation. My flaxseed oil self-experimentation played a big part, although it had nothing to do with mouth health. These experiments showed dramatic benefits — so large and fast that something in flaxseed oil, presumably omega-3, had to be a necessary nutrient. Because of these results, I blogged about omega-3 a lot, which is why Eric emailed me about his experience.
3. Unconventional evidence. All the evidence here, not just the self-experimentation, is what advocates of evidence-based medicine and other evidence snobs criticize. Much of it is anecdotal. Yet the evidence snobs have, in this case, nothing to show for their snobbery. They missed this conclusion completely. Nor do you need a double-blind study to verify/test this conclusion. If you have canker sores, you simply drink flaxseed oil or eat walnuts and see if they go away. Maybe this omnipresent evidence snobbery is . . . completely wrong? Maybe this has something to do with the stagnation in health research?
4. Lack of credentials. No one involved with this conclusion is a nutrition professor or dentist or medical doctor, as far as I know. Apparently you don’t need proper credentials to figure out important things about health. Of course, we’ve been here before: Jane Jacobs, Elaine Morgan.
5. Failure of “trusted” health websites. Health websites you might think you could trust missed this completely. The Mayo Clinic website lists 15 possible causes — none of them involving omega-3. (Some of them, we can now see, are correlates of canker sores, also caused by lack of omega-3.) If canker sores can be cured with walnuts, the Mayo list of treatments reads like a list of scurvy cures from the Middle Ages. The Harvard Medical School health website is even worse. “Keep in mind that up to half of all adults have experienced canker sores at least once,” it says. This is supposed to reassure you. Surely something this common couldn’t be a serious problem.
6. Failure of the healthcare establishment. Even worse, the entire healthcare establishment, with its vast resources, hasn’t managed to figure this out. Canker sores are not considered a major health problem, no, but, if I’m right, that too is a mistake. They are certainly common. If they indicate an important nutritional deficiency (too little omega-3), they become very important and their high prevalence is a major health problem.
