Allergy Testing For Food, Pollen, and Molds

3 Dec

Allergy Testing ArmI recently had a series of allergy tests done – 5 sets in all – to see if I was allergic to anything to the point where I should be carrying an EpiPen, and then to learn more about non-allergic adverse reactions to foods and other things, such as my reaction to the nightshade family (potatoes, peppers, tomatoes, eggplant, kava, and tobacco).

During the testing, I had to lie down on a table and the technician brought in a tray of allergens in a theme, such as major or minor foods, then pollens/grasses/trees/molds in various combinations. For some they wanted further clarification, so shots were injected subcutaneously into my arm after the testing on my back was completed.

The skin testing helps determine what you would react to in a severe way, possibly requiring the use of an EpiPen to prevent anaphylaxis if encountered. While I have many adverse reactions to foods, I know that only about 1-3% of adults have true allergies to foods so I wasn’t thinking I would show any positives in those tests. My doctor explained that a person may still have adverse reactions even if they don’t show on the skin test, but that those are not likely to result in life-threatening ways, so other options are available for treatment, such as taking a certain antihistamine cocktail for a few days before trying them out. He really took the fear out of food reactions for me, as most of mine, while fairly unpleasant, only last a couple of days, and I realized that if I was stuck somewhere with no other food source, I would not starve because I would bite the bullet and eat what was given, even if I felt sick for a bit after.

The skin test is a little prickly and then itchy, especially where they poke you with the pure histamine which is used as a control to make sure they are getting a good reaction –  I was instructed to be off all antihistamines, including those for acid reflux, for 5 days before each set of testing as they can interfere with the results. I had to lie there in the little room for 20 minutes each time while I felt all sorts of itchiness occurring and really wanted to scratch my back but instead found something to read to distract myself. The results are determined by measuring the urticaria or wheals that form and then the redness circumference around the wheal, so a positive would have a wheal of >3mm wide and redness >10mm wide, or written as 3/10.

I found out that the only two foods I have a true, skin-testable allergy to are red pepper (3/13) and lobster (6/30 – my wheal for lobster was as wide as the histamine!) Allergy to one shellfish gives a 75% likelihood of being allergic to other shellfish. I was surprised I didn’t have a positive test for oranges, as I have had a reaction in the past after drinking some juice and having some fresh. I did test positive for many pollens from grasses, weeds, and trees, as well as molds, and this can explain why some foods are allergenic when consumed, as some pollens are very similar in structure to food proteins, which may cause a faulty allergic reaction in the body when consumed. An example is being allergic to birch pollen might give you an adverse reaction to apples, peaches, or melons.

With the results in, I am looking at the way I eat food a little differently. I was told by my allergist the more I avoided certain foods that didn’t provide a true allergic reaction, the more sensitive I would be to them, such as potatoes. That instead of eating less of them over time and getting more reactive, I would have been better served to keep eating them to maintain my body’s ability to tolerate them. I’d wondered about that in the past, so am looking forward to future appointments where we discuss strategies to maybe make it possible for me to regain some of those forbidden foods in my diet.

I’m not suggesting anyone do this out there without the help of a doctor, but if you haven’t had allergy testing and have problems with specific foods, it may be worth your while to make an appointment. It’s worth a shot! ;)

Summer Break, Gardens, and Happy Hour Sushi

3 Aug

Globe ArtichokeI haven’t been doing much writing this summer, but I plan to get back on schedule this fall. It’s been one busy summer!

Things kicked off with my birthday in June, and two days later I started summer school classes (Statistics and Political Science) which required non-stop studying and writing which reduced the writing itch as well as changed my focus from nutrition.

In my spare time, I tended my first vegetable garden in four years, and renewed my efforts toward keeping up my yard’s fruit trees. I planted watermelon, yellow squash, zucchini, cucumber, butternut squash, three kinds of beans (green, wax, and purple), globe artichokes, Jerusalem artichokes (actually, they planted themselves), and some basil. The yellow squash and basil both failed to thrive, however the cucumber is working in a professional capacity, and the artichokes have already put out several small chokes. If I collect beans for a week, then there are enough for two, and while the zucchini plant seems to visibly take over the garden, it hasn’t been putting out. I did finally see a couple of small watermelons though which gives me hope I’ll get a few of those before the growing season ends.

The funny thing about zucchini that doesn’t seem to apply to any of the other squash is any contact I make with the leaves gives me a mean-looking rash. It’s like a stinging nettle reaction and usually goes away by the next day unless I get a bad spot; then it lasts for a week or so. I’m usually suspicious of eating anything that reacts with my skin, however zucchini never seems to cause any problems, so I keep watering and hoping it’ll give me something more to work with.

Nothing says summer to me like drizzling chopped zucchini, red onion, and mushrooms with Bragg’s Liquid Aminos (like soy sauce however it’s not fermented and therefore doesn’t contain any aspergillus fungus, nor does it have any other ingredient than soy) and some olive oil and grilling on the bbq in a grill basket.

Another indulgence this summer has been hitting the downtown sushi restaurant, The Raw Bar, for its happy hour, so I can enjoy a couple of cut rolls while people-watching as the restaurant faces the downtown park quad. Sushi is a favorite of mine, as long as I bring my own Bragg’s, because I can usually find something to eat without any special help.

Raw Bar Happy HourPhilly rolls, which contain smoked salmon, cream cheese, and green onions wrapped in rice and seaweed, are a favorite. I do like to request my own special roll, however, and most places I’ve gone are more than happy to accommodate my request. In fact, The Raw Bar is thinking up a name for it since I request it every time. My custom roll is: tuna, avocado, daikon radish, green onion, rolled inside out with sesame seeds and tobiko (flying fish roe) on the outside. Delicious with some Bragg’s and wasabi. I skip the ginger because it usually contain citric acid. For those sensitive, some sushi restaurants use seasoned rice vinegar in their rice which does contain a little corn syrup; often times the wasabi contains corn starch, so be careful if you are sensitive.

Unfortunately, I decided to venture out of my safety zone and ordered a different roll I thought might be ok for me to eat, but I discovered just as I was swallowing my first bite it contained tempura. It was the first time I had any gluten grain in my mouth and known about it in several years. I didn’t know what to do! And my waitress was very attentive and apologetic, saying she knew I brought in my own soy sauce but didn’t put two and two together and realize I was gluten-intolerant because people who have Celiac disease usually bring tamari instead. In actuality, I should have been the one to say something to begin with, but have had such good luck with sushi restaurants I had gotten careless. At any rate, I greatly appreciated the concern and care taken in making sure I had something else to eat and made sure I showed up the next week so she knew I survived.

It’s tough with me and gluten, however, because with this exposure, it took several days to become obvious. I think it may have to do with how long it’s been since I’ve had any gluten, so it was subtle at first. However, about five days later, the familiar head-crushing migraine “storm” struck and then the stomach problems, the aching all over in my joints, and the emotional roller coaster that lasts for about three weeks.

The gluten reaction even kicked up a major Interstitial Cystitis flare, complete with pelvic floor spasms, which surprised me as I hadn’t considered they might have any relationship. I think the common denominator may be firing up of the abdominal nerves and inflammation caused by the autoimmune reaction. At any rate, I survived ok but there was a rough week or two in there where I once again felt strongly resolved in my making gluten a thing of my past.

I’m still trying to understand how food reacts with the body and hope to learn more this fall as I learn more about organic chemistry and physiology. And I’ll post some new recipes I’ve learned and concocted this summer.

Thanks for reading!

How Food Allergies and Intolerance Affect Nutrition

22 Mar

celiac sprue associationThis is a big can of worms that I’m going to start discussing the next few posts. However, I thought it would be good to get it started with just this simple information.

Food allergies and intolerances have multiple effects on nutritional status. The primary effect of having a food allergy or intolerance is the potential lack of nutrients due to the necessary avoidance of that food or related foods.

Fortunately, there is a wide array of food options available for substitution so that nutritional needs can be met, with a little education.

Food reactions can make it biologically more difficult for ingested food to be processed properly, for example in the case of Celiac disease, the consumption of gluten-containing foods results in gastrointestinal effects which decrease absorption of nutrients in the small intestines through conditions such as villous atrophy, intestinal inflammation, and changes in bowel habits.

Additionally, stress on the biological system due to food reactions and uninformed food avoidance can overdraw the body’s reserves of essential nutrients leading to deficiencies that may need to be resolved through use of vitamin and mineral supplements.

Peanut Allergy: More Than A Hill of Beans

22 Feb

It’s hard to know if it’s the prevalence of food allergies that’s on the rise, or if it’s the increased awareness of this previously under-diagnosed problem. However, one of the most deadly food allergies, peanut allergy, has seemed to become increasingly common in just the last 20 years.

The reason for this seems fairly inexplicable – I, myself, didn’t know a single person when I was in school (70′s through the 80′s) who had an allergy to peanuts. And yet now, cafeterias, classrooms, airplanes, even designated sections in ballparks, are all peanut-free, due to the extreme nature of this allergy, which affects approximately 2% of people.

Most are children, and even the little bit of peanut that gets airborne is enough to cause a reaction that involves closing the throat and windpipe of the affected. People with peanut allergy are likely to need immediate medical attention even if they are exposed by eating at the same table as someone else who has a peanut butter sandwich.

How did this happen? Is it something about how peanuts are grown? Is it something to do with a combination of peanuts and pesticides? Do organically grown peanuts cause the same reaction? Why has this reaction skyrocketed in the last two decades?

There is news today that researchers in England may be on the trail of what happens to those who suffer this allergy, and they are preparing the largest trial to date of children, ages 10 through 17, to see if the cause can be determined. It is hoped, that the results of the study will help researchers find a cure in about three years’ time.

Peanuts are an incredibly nutritious food, a part of the legume family, providing good unsaturated oils, proteins, and fiber as well as various minerals. I’m hoping they are able to find a cure to this allergy, because that gives me hope for those who currently suffer issues related to this allergy, plus hope for answers and cures for the many other food allergies out there.
