I am not talking about allergies, but about milder food intolerance. How do people approach this to quantify and measure it? I have read that most serum lab blood tests are useless. Prick tests? Elimination and reintroduction seems to be the consensus, but still there is nothing quantifiable. Do people use blood glucose measurements to determine their food intolerance? Some people use heart rate or heart rate variability(HRV) changes while eating particular foods. Please share your strategies!
An allergy is to a protein, a sensitivity or intolerance is referring to a non-protein food issue. My strongly preferred method to determine these in a body is elimination and reintroduction of potentially offending foods. I've seen wrong information with so many of the tests available, and observation of one's own body's reaction can't be beat, imo. I recommend a full three weeds of strict avoidance of the foods in question, then allowing a full 72 hours per food during reintroduction time with notes taken on any symptoms that may emerge.
My comments definitely relate only to mild reactions--no one suspecting a true allergy should follow my suggestion.
Prick tests were useless for me. I tested negative for allergy to wheat, yet I found out after going primal that wheat caused my stuffy nose and sneezing, GERD, and joint problems.
In answer to your question, I did use the eliminate-and-reintroduce method to check my reactions. Wheat was 90% of my trouble and I actually did fine with sugar but not milk.
I checked both my blood glucose and blood pressure frequently to verify what I was feeling. Wheat wasn't subtle, it made me feel really crummy. Milk did about the same. No major reaction to corn chips.
Funny I'm going through a blood test, and an elimination diet right now... To see what my food sensitivies are... They are basing everything off of how I feel or bloat when I eat certain foods. I feel awesome after eliminating gluten and wheat from my diet... And its only been 5 days... I'm basing this off how I feel and what I think is right for me!
Something I heard, maybe someone can back me up- Doesn't excess mucuous production (extra phlegm in the back of your throat) signal a sensitivity? I get that immediately after consuming sugars or low fat dairy.
IgG testing can reveal delayed reactions to food, such as food sensitivities, that otherwise won't be detected in traditional IgE allergy testing: http://gut.bmj.com/content/53/10/1459.short
I had the prick test done it is was negative for everything. I have been gluten free for almost three years and while it helped the bloating I am still dealing with other issues. My chiropractor gave me a script to have an IGg blood test done. It said that anything over 2 was condidered high..my results was Wheat-9.9, egg yolk 9.7, dairy 6.7, soy 4.0. (I found it interesting that gluten was the only one that was completely negative as I had been gluten free for almost 8 months at that time) I never really did anything with the results as the Chiroprator made them seem insignificant stating that he has seen people with a results of 100. The only one I have kept with is the wheat/gluten. But I am thinking I need to stay away from the others as they did show a reaction. Any thoughts out there?
I've found that blood tests and my own 'eliminate and reintroduce' efforts confirmed what several different homeopathic tests found. I've never had a prick test.
So I feel comfortable suggesting the blood tests along with homeopathic tests (even though they seem weird and kooky).
I eliminated what (felt great) and then re-introduced it (felt awful). However, would this be classified as a wheat intolerance? Perhaps my body is just highly sensitive after the elminationg of wheat. I haven't had any major problems with wheat prior to trying this, but after elimination/re-introduction, I experienced extrement bloating, gas, etc.
Prick testing is for immediate-onset allergies (IgE?). Think hives after shellfish, or anaphylactic shock after peanuts. They're not going to tell you anything about delayed onset allergies or sensitivities. (This from a mom who had her daughter tested with prick tests to try to diagnose her eczema and was told the kid was allergic to dust. Um, thanks, doc.)
