Dietary Deficiencies
Certain dietary deficiencies have been linked to an increased risk of canker sores. Diet plays a role in canker sore formation, and certain deficiencies have been linked to an increased risk of canker sores. For example, vitamin B12 or iron deficiency can make canker sores more likely. These nutrients are found in poultry, eggs, beef, and dark leafy greens. Therefore, including these foods in your diet may help to reduce the risk of canker sores.
Other potential causes of canker sores are the lack of folic acid, zinc, or iron in your diet. If you think you may be deficient in one of these nutrients, talk to your doctor about increasing your intake. In addition, some research suggests that calcium deficiency may play a role in aggravating existing canker sores or making them more challenging to treat. However, more research is needed to confirm these findings. In the meantime, if you experience frequent canker sores, it may be worth ensuring that you get enough calcium in your diet.
