What the heck, Apples?


| 5 Comments

Apples are my favorite fruit. I love apple juice , apple pie, and apples with peanut butter ! They are all very healthy and good tasting. I can't imagine waking up one day and not being able to enjoy one of my favorite fruits . Sadly this has been the case for many people recently !

As usual apple lovers they go to enjoy a healthy snack but this time around something is very different ! With every bite they are realizing that their mouth and throat is getting itchy and eventually swollen ! How is this possible? What is happening ? They were never allergic to the fruit before so what is going on now?

Dr. Chris Webber of Denver , Colorado is an allergy and immunology specialist said that the weird new allergic reaction can be "surprisingly common". - Nbc.com Its called Oral Allergy Syndrome also known as (OAS) . OAS can occur in adults who have hay fever reactions when eating raw fruits and vegetables. These reactions are not life threatening but are very bothersome and uncomfortable. It is usually described as an itchiness of the throat and mouth. In some people there has also swelling of the throat (yikes).

Moving on; the big question to me is how can this happen if people are eating apples their whole life ? Why is it all of a sudden a problem? The answer I found is very surprising. It turns out that the OAS reaction is not coming directly from the food that you think it is. What is actually happening is you are having an allergy to pollen. The OAS is your body "overreacting" to this allergy. This is effects of you immune system trying to protect you.

 

What happens is when your body produces a pollen allergy your body produces anti-bodies that are created in order to fight off illness. What happens is when you are eating your apple your body picks up the trace if the pollen! And all at once your snack has triggered a very unpleasant itchy experience.

I found a study testing this experience exactly.

The study took 37 people some with OAS and those without. They exposed them to the apples with traces of the birch pollen on them. Those who had OAS did in fact have reactions fitting descriptions as shown above. The conclusion is that you will only get the reaction from the apple with birch pollen if you have devolved an allergy to the pollen and currently have the OAS. If you do not have OAS the individuals body did not react to the pollen that was present. This explains why some people have this reaction and other do not. It also explains why some people do not have the allergy yet but may develop it later in life.   

Study credit :  D. G. Ebo, C. H. Bridts, M. M. Verweij, K. J. De Knop, M. M. Hagendorens, L. S. De Clerck and W. J. Stevens, Clinical & Experimental Allergy, 2010 (40) 339- 347.

GOOD NEWS! There is a way that you can avoid this if you have OAS and still enjoy your apple! The pollen traces your body picks up come from the outer skin of the apple! If you eat around the skin or peel it , you should avoid the triggering OAS from the traces of pollen left from the apple!

I can relate to this and I’ve always wondered what causes this. Whenever I eat apples, peaches, carrots, snow peas, and certain nuts my throat becomes irritated. My mouth starts to itch and with apples especially my lips feel like they’re swelling. Most people I tell about this think it’s a problem and that I shouldn’t be eating these fruits, veggies, and nuts. But usually nothing serious happens in terms of allergic reaction so I keep eating them. I’ve always thought it might be something to do with pesticides used to preserve the fruits and veggies but the idea that pollen causes the allergic reaction would make sense because I’m also allergic to that as are most people. I wonder if there are ways to eliminate this reaction by means other than not touching the skin of these veggies and fruits. The oral allergy system is interesting in the way it affects so many people in the millions with almost 70% of people having allergic reactions. This news report from U.S. News is very resourceful in talking more about this issue and mentions a lot of what was said in your article.

I absolutely love eating apples so your blog post caught my attention quickly. I can definitely believe that pollen has an affect on humans and causes allergies. I also got to thinking that maybe pesticides on fruit and vegetables can cause allergies too. Here is a website that supports this idea and gives tips on how to less expose yourself to pesticides. http://www.rodalenews.com/food-allergy-causes
