Fruits and canker sores

Pineapple and canker sores
Some fruits are also often listed by scientists as believed to be a major cause of canker sores.

The fruits which are most often cited as leading to or aggravating existing canker sores are:

  • Pineapples
  • Bananas
  • Citrus fruits (oranges, grapefruit)

The pineapple is a fruit with the enzyme bromelin (belonging to proteases family), which makes digestion easier and has anti-inflammatory quality. Pineapples are also an important source of manganese and vitamin C.

Bananas and canker sores


The banana is a highly digestible, high -energy fruit (90 kilocalories per 100g). The banana is also so rich in potassium that one banana a day covers one's daily needs.

Citrus fruit are very rich sources for vitamin C.

Thus, avoiding eating fruits because one has canker sores can lead to other, more severe problems.
