oral allergy syndrome
Some people experience itchiness in their mouth and throat, sometimes with mild swelling, immediately after eating fresh fruit or vegetables. This is known as oral allergy syndrome.
Oral allergy syndrome is caused by allergy antibodies mistaking certain proteins in fresh fruits, nuts or vegetables for pollen.
Oral allergy syndrome generally doesn’t cause severe symptoms, and it’s possible to deactivate the allergens by thoroughly cooking any fruit and vegetables.

food intolerance
A food intolerance isn’t the same as a food allergy.
People with food intolerance may have symptoms such as diarrhoea, bloating and stomach cramps. This may be caused by difficulties digesting certain substances, such as lactose. However, no allergic reaction takes place.
Important differences between a food allergy and a food intolerance include:
the symptoms of a food intolerance usually occur several hours after eating the food
you need to eat a larger amount of food to trigger an intolerance than an allergy
a food intolerance is never life threatening, unlike an allergy
