"Unwittingly." I Do Not Thing That Word Means What You Think That Word Means.

I had a whole other topic for today, but then I ran across this article from JAMA: Treatment Rather Than Avoidance May Be Within Reach for Children With Food Allergies. There's a section in there that really burns my butt:

"A number of hypotheses attempt to explain the rise in food allergies in the United States and other developed countries. One is that parents may have unwittingly [my emphasis] made their children more prone to food allergies by delaying the introduction of potentially allergenic foods in their babies' diets and following World Health Organization guidelines to exclusively breastfeed for the first 6 months."

Are. You. F-ing. Kidding Me? Why are the parents the unwitting (which I am choosing to define as "wit-less")  ones? Where's the line that says "oops, sorry, we doctors and scientists may have given you the wrong advice." 

Our doctor told us, straight up, avoid peanuts and tree nuts with subsequent children. Having done quite a bit of reading on the topic, I did not follow the advice, and I still do not believe the "window of introduction" for foods has anything to do with food allergies. Mother Nature is not that fickle and too many of us recognized reactions in our children to allergens in our breast milk long before these allergens manifested in full-out reactions to solid foods. But it just makes me crazy that now another entire generation of food-allergic moms is going to question whether their children's allergies are their fault

Repeat after me, scientists and doctors: correlation is not causation. There are hundreds of other possibilities for why Israeli children do not exhibit peanut allergy at the same rate as American children.

The smoking gun that I see is the difference in "living foods" and the subsequent colonization of gut microbes. Americans have lousy guts because we no longer eat a traditional diet, using foods that aren't processed or so long from the farm that they're already "dead" by the time they reach us. Don't believe me? Consider this study from 2011 that shows MicroRNAs from the foods we eat pass intact through our guts and reach our blood stream. 

I've been pulled down some odd paths in my life, and this (admittedly somewhat granola) belief in the power of foods to heal is one of them. Unfortunately, it's a road our physicians and scientists have little reason to travel. 

Buried in paragraph eight of this article is this line: "Bacteria in the gastrointestinal tract aren't regulating allergic immune responses as effectively as they did in the past, so children are reacting to more potential allergens." Funny how that never ends up the headline.

Best Food Allergy Tweets/Posts From 2013 ACAAI Meeting

Sorry, guys...I've been very busy the last couple of weeks, but just over a week ago one of the largest allergy and asthma conferences, the annual American College of Allergy, Asthma and Immunology, was tweeting its brains out.

Here were the tweets and (virtual) presentations I thought were most interesting:

ACE inhibitors are often used to treat high blood pressure. I believe Lisinopril was the one specifically mentioned. This goes hand in hand with the idea that older patients, especially men, can see changes in the severity of their allergic reactions as they age.

Here's an answer on the question many of us asked about component testing. Just as with RAST, the number itself doesn't matter; just the positive result.

Gross! But yes, give your kids the bobber after the dog/ brother/ mailman licked it.

Conversely, tree-nut-allergic individuals have a 30% incidence of concurrent peanut allergy. 
So stop blaming yourselves, FA mommies! I've said this consistently - Mother Natur…

Taking The High Road With Food Allergies (Sometimes)

I was getting all ready to write a post about how grateful I am. You know...one of those count-down-to-Thanksgiving posts where I list all the people or things that have helped me along the way.

And I am grateful. Really. Having virtual friends who have traveled this same food-allergy road is a wonderful gift. I can name so many times when my panic and frustration were alleviated by someone I've never even met in real life, but who took the time to give me a tip, or to console me.

But frankly, my lovely gratitude post went out the window when I received this email from a relative:

What can we bring to share? I have some ideas: Sweet Potatoes glazed with Chutney and Ginger, Green beans with Dijon and Caper sauce, Creamed Green beans with Dill sauce, or whatever you request.   I am aware of [FAB's son] dietary restriction.

My son is allergic to beans. We avoid all beans. Even green beans. The doctor was surprised by this, as green beans are the least allergenic of the bean family, b…

Beans, Beans and More (or Less) Allergenic Beans!

We have a little good news this week: my son passed a home bean challenge for both pinto and cannellini (white) beans last night. Hooray!

At our last allergist visit, they ran the numbers on a number of varieties of beans and many were Class 0, with values like 0.68. My son's doctor thought it was reasonable to try these at home.

Going to stop for a moment and interject: DON'T DO THIS WITHOUT YOUR DOCTOR'S DIRECTION. A lot of things go into whether home challenges are a good idea for your child: how serious the allergen typically is, how far the hospital, how experienced the parents are with recognizing reactions. Many doctors are not comfortable with this at all. But, in our case, it makes sense to do some challenges at home because my son tests slightly allergic to dozens of foods.

He has avoided all beans since around age five, when he started developing new allergies. First it was tuna. Then cashews. Then (to our great surprise), he suddenly became allergic to garbonzo be…
