Allergic reactions to
fruit and vegetables are usually mild and often just affect the mouth,
causing itching, a rash, or blisters where the food touches the lips
and mouth. This is called oral allergy syndrome.
A number of people who react in this way to fruit or vegetables will
also react to pollen from some trees and weeds. So, for example, people
who are allergic to birch pollen are also likely to be allergic to
apples.
How ripe a fruit or vegetable is can also make a difference. For example,
tomatoes are more likely to cause an allergic reaction the riper they
are.
Where do Fruit and Vegetable Allergies come
from?
Ragweed allergy (which causes hayfever in August and September), can
be associated with allergies to raw bananas, and the members of the
gourd family (melon, watermelon, honeydew, cantaloupe, zucchini and
cucumber).
Grass allergy can be associated with allergies to orange, melon, watermelon,
tomato, kiwi, peanut.
These allergic reactions usually occur only when the food is raw.
People who are allergic to the raw food can eat it cooked, canned,
microwaved, processed or baked. For example, someone allergic to raw
apples can eat apple sauce, apple jelly, apple juice, apple pie and
dried apples. Generally, cooking fruit and vegetables makes them less
likely to cause an allergic reaction. Pasteurisation and other heat
treatments (which are used, for example, on fruit juices) have the
same effect. However, this is not the case for all fruit and vegetables.
For example, cooking celery doesn’t make it less likely to cause a
reaction. This problem is usually life long. Allergy tests to these
foods may sometimes be negative unless a fresh fruit is used for the
test (instead of a commercial allergy extract). The allergic reaction
to these foods can occur anytime of the year when eating the foods
but can be worse during the pollen season and especially if hayfever
is very troublesome that year.
The allergic reaction is not due to pesticides, chemicals or wax on
the fruit. However because the more allergic part of the fruit may
be in the skin, some people allergic to fruits (i.e. peaches), can
eat the flesh without reaction if the skin is peeled away. Similarly
for apples, some brands of apples cause more allergic reactions than
others. Freshly picked apple (i.e. straight from the tree or an unripe
apple), may cause fewer allergic reactions than one which is very
ripe or one which has been stored for weeks after picking.
