Have you ever felt tired immediately after eating a meal? Do you have uncomfortable bloating or indigestion, or experience frequent headaches? These are all signs of a possible food sensitivity.

Food Sensitivity vs Food Allergy

Though they sound similar, food sensitivities are different than food allergies. A food allergy triggers an immune response that can affect several organs, and the reactions can be serious, or even life-threatening. A food sensitivity, on the other hand, usually results in more mild symptoms that might not even be noticed right away. That’s when testing can come in handy.

I recently tried out the EveryWell Food Sensitivity Test, which tests your body’s IgG response to 96 different foods, to see if I could narrow down some food sensitivities of my own. (I’ve suspected that I’m sensitive to peanuts, as well as gluten and dairy.)

How Does EverlyWell Work?

EverlyWell makes at-home testing easy. You order a test online (be sure to use the discount below) and then it’s mailed to your door. They send you everything you need to perform a simple blood collection at home, then you mail the sample to one of their certified labs using a pre-paid shipping label. You’ll get your results in just a matter of days.

How Accurate is the Food Sensitivity Test?

The food sensitivity test is based on IgG reactions, which are more likely to show up to foods that are currently in your diet. So, it’s possible that you may not see reactions to foods if you haven’t eaten them in a while. If you suspect that you’re sensitive to a food, it’s a good idea to eat it for 4 weeks before taking this blood test, so that it’s more likely to show up in your results. (If you have a noticeable reaction while eating this food, then you already have your answer and don’t need to eat it for the full 4 weeks.)

Just because a food reaction shows up on your test, doesn’t mean you’ll always have a noticeable symptom associated with that food, either. I’d consider this food sensitivity test as a jumping-off point for an elimination diet, which should give you an even more accurate account of how certain foods may affect you.

For example, I recently took EverlyWell’s Food Sensitivity Test and my results looked like this:

So, my next step might be to start an elimination diet by cutting out those top 7 foods for 4 weeks.

Then I’d reintroduce each food, just one at a time so I can identify reactions. For example, I might start with cheddar cheese. I’d eat it once, then avoid it for the next 2-4 days following that to look for symptoms. If I notice a headache, bloating, or stomach pain after eating cheese for the first time– after not eating it for 28 days– that might be a pretty accurate sign that I have a sensitivity to that cheese.

I may consider eliminating some of my mild sensitivities, too. (Though cutting out chia seeds will make me sad, and cutting out lemons may prove impossible for me.) The following are my mild reactivity results from the EverlyWell test:

Is EverlyWell Legit?

EverlyWell works with leading specialty labs in the United States who are all CLIA certified. You can take the same test at a doctor’s office, but insurance doesn’t always cover it, so this is an affordable at-home option.

I’ll be using my own results to start an elimination diet to see which foods affect me and which may not, so stay tuned for that!

A friend recently did IgG testing with a doctor and the doctor mentioned that if you have a mild reaction to something you eat a lot of, it could be a false positive, especially if it’s not known to be a problem food usually. So, for example, maybe the chia seeds are a false positive for you. Does the kit say anything about that?

Recently I had a test done. Extremely sensitive to eggs, dairy(in particular casein)gluten, yeast, soy, almonds and hazelnuts. But all grains really affect me. I have eliminated all for almost 3 months. Don’t plan to reintroduce any time soon. Food is now very boring. Oh well.


Did an indent allergy mail away test…Three Tests: Intolerance, Nutrition Genetic & Digestive Healt. Cut my hair and it in. I had to answer questions and wondered if they based some of the results on that. I already knew I was lactose intolerant and had a sensitivity to gluten. So those both came back as being intolerant. But it also said I was I tolerant to buckwheat which is not gluten. So I was a bit confused on that since that does not contain gluten. Also said I was Intolerant to cardamom which is included in my chai teas 😔.


Several of these foods are high in histamine. Maybe trying a low histamine diet would help. It’s definitely helping me. Good luck!

Oh my gosh – such a seemingly long list! I’d be so discouraged. Good luck with the elimination diets, I’ll be following along.


I’m curious to hear how this goes for you and if you see any notable differences. I had an IgG test done through my neurologist (migraines) a couple of years back, and the results came back pretty much with “food” (granted, most were very low/low reaction, but still…). What then bothered me, though, was how I could have a reaction to milk/casein/yogurt, but none to cheddar cheese or mozzarella? When I did some online research, it seems that IgG testing is still not scientifically validated and could potentially indicate a tolerance vs. an intolerance. I know that EverlyWell has some research studies in their FAQs, but I’m still somewhat skeptical. I later had a completely different food sensitivity test done (LRA by ELISA/ACT, which also includes IgG and tests for 238 food items) and my test results were COMPLETELY different (aside from two items). So…I don’t know what to believe. I wish there were a magical answer or 100% completely validated research. Do you have any thoughts about the validity of the test? I know you typically like to do your research. 🙂 Also (and I hope this doesn’t come off rude, because I totally don’t intend it that way at all): I’m wondering why you would potentially attribute seasonal allergies to food vs. something…seasonal? Like air particles/plants, etc?

    Hi Erika! I think the gold standard for determining food sensitivities is doing an elimination diet, so I consider this sort of test to be merely a starting point. I’d never eliminate something forever based on these results. I mentioned my seasonal allergies because I’ve read that some allergy symptoms can be worsened if your liver is overtaxed, which could be caused by eating foods that don’t work well with your body. Hope that makes sense!


      It does; thanks for the reply!


I ordered my kit! Curious to see if it’ll confirm what I think is a sensitivity to dairy.

Hi Megan! I’ve ordered two of your cookbooks and am loving them! You’ve made me not fear the Instant Pot now. lol I’m on the fence as to whether I should take this food sensitivity test because two years ago, I took a Cyrex lab test that showed I had high reactivity to egg whites, almonds, scallops and dairy. Haven’t done the official gluten test but wondering if this test will show my intolerances have changed.Do you think it’s worth it to try testing again or should I stick with my results from two years ago. I have Crohn’s disease but am in remission because I’m really strict about my diet and steer clear from the triggers. I’m attracted to the cost of this testing as it is about $150 less than Cyrex but not sure if it is as accurate. Thanks for letting me know your thoughts 😎
