Foods that are Helpful

Iron-rich Foods

Intake of foods that are rich in iron goes a long way in combating the mouth ulcers, particularly if you are having heavy monthly periods that deplete the body stores of iron, or symptoms of iron deficiency such as weakness, tiredness or breathlessness. Such foods include green leafy vegetables, dried fruits, pulses and meat.


Vegetables and Meat

Vegetables that are cooked tend not to have abrasive qualities and are good for your health in general. Meat or non-vegetarian food in general tends to be acidic. But unseasoned meat tends to have a neutral pH and so is not harmful.


Onion and Garlic

Onion and garlic are rich in antioxidants that help fight the disease. So, you can either eat them raw or use them liberally in your cooking.


Cold Beverages and Foods

Cold food items soothe away the pain of mouth ulcers. So, having iced tea, cold milk or ice cream is a good idea.
