Allergic Reactions to Fruit and Vegetables Which are Annoying, Not Dangerous

When you talk about allergies for some time, eventually you will find people who tell you that they have an allergy from fruit and this can often be quite a wide ranging fruit allergy. A colleague said to me recently:

"I can't eat apples. I also can't eat pears, plums, cherries, peaches, and incidentally carrots, or celery can be the same as well at times. When I do try these, because I really do try to ignore it, my mouth within moments feels like it's burning, and my palate itches and it leasts a few minutes, so I resolve once gain to leave fruit alone. I have been to see the doctor several times and he says that I, amongst probably a few million people, have a condition called 'Oral Allergy Syndrome', which means that for me and so many others these tasty and most healthy of vegetables and fruits have to be avoided, at least when they are freshest."

Organic Fruit

This is a great shame and prevents a lot of healthy eating for sufferers. Allergy specialists estimate that 70 percent of people with allergic rhinitis, or hay fever, have some form of Oral Allergy Syndrome.

The big surprise is that many doctors haven't heard of it.

The root cause of the problem is normally the presence of fruit-pollen. Fruit-pollen syndrome as it's often called, is far less dangerous than the well known food allergies to milk, eggs, wheat products, and the best known of all of these is peanuts. (This has been due to our food processors in the past having cross contaminated small amounts of peanut into other products with some disastrous effects upon the unknowing sufferer, even at remarkably low peanut concentrations.

The medical profession refers to these food allergies which can have such big effects as "priority allergies", because they trigger systemic reactions and are more likely to induce a fatal response than other allergic forms.

A fruit allergy, can strike unexpectedly in adulthood, recently and before I had heard of fruit allergies, I was surprised when my friend Sarah Relph, who is in her thirties, said:

"I suddenly appear to have developed an allergy to fruit: apples, ... But, oddly enough, the allergy is only to FRESH fruit; not preserved, canned, or cooked, and only to fruit that is grown in the country where I now live."

A recent post on a forum also reads:

" ... I am a 34 year old Asian male, I seem to be allergic to fruits, like apples, cherries, plums, peaches (also itchy lips, and throat). And the worst seem to be the freshest."

To the allergy expert this is readily explainable, and not really as perverse as many sufferers see it.

The fresher the fruit, the more pollen will be present, and it is this pollen on the fruit that in a sufferer their body's antibodies within their immune system are unable to differentiate from an infectious agent and see the fruit as being an invasive infection, giving rise to the symptoms described.

Quite quickly the proteins on the surface of these fruits will oxidise, and once they do the allergic reaction they can produce tends to go as well.

There are ways for sufferers still to eat fresh fruit. For example, placing the fruit is a microwave for about 30 seconds (not long enough to really heat it, but enough to bring the incidence of unoxidised viable pollen spores down by orders of magnitude compared with when fresh.
