While they may not be such a big deal in the grand scheme of things, canker sores are still a pain. They can cause unpleasant oral aching, as well as serious bad breath. Recently, a U.S. professional cyclist announced that this canker sores disappeared after he switched to veganism.
David Zabriskie, a 32-year-old road bicycle racer who will participate in the Tour de France for the sixth time this year, told the UK Daily Mail that abandoning meat, eggs and dairy products in favor of protein-rich seeds and rice has actually boosted his performance.
He added that his canker sores and saddle rash have disappeared following the switch.
Several sources note that dietary changes can help treat canker sores. For instance, a study published in the Journal of the American Board of Family Medicine found that increasing one's level of vitamin B12 may help these oral lesions heal.
Since the sores are also caused by irritation, many dentists recommend avoiding toothpastes and mouthwashes containing harsh chemicals like sodium lauryl sulfate, which can inflame the cheeks and gums.
Using a specialty breath freshener instead can lead to healthier gums and sweeter breath, even without a drastic change in diet.
