Quote Of The Week: Food Sensitivity Testing

Have you ever taken a food sensitivity test and had the results come back negative for foods you know you react to?

It may mean the lab test you did was inaccurate. Maybe the lab only measured IgG antibodies whereas your immune response was an IgM, IgA, or IgE response.

Different types of immune responses involve different antibodies. Some labs only evaluate one set of antibody responses.

Also, some immune reactions to foods are not even immunological, they’re neurological or vascular, or they involve aflatoxins, preservatives, or additives, which the labs do not screen.

Positive to everything

On the other hand, what if you test positive to almost every single food on the lab panel? This means you may have lost immune tolerance.

When you lose immune tolerance, you start reacting to almost every protein that comes into the body. If you remove all those foods from your diet, you’ll eventually start reacting to the foods you are still eating. This is a very frustrating cycle for patients.

Does fixing leaky gut fix food sensitivities?

While leaky gut can lead to food sensitivities through increased immune activation and improper breakdown of food proteins, it’s not always the magical cure-all.

Whether repairing leaky gut takes care of food sensitivities depends on concepts such as the severity of the reactions, immune tolerance, and other inflammatory factors taking place.

Yep, agree with all of that. It’s a complex science. Nowadays, I use food testing to help people find their ‘healing diet’ and usually advise a Cyrex 3x if still on gluten because we need to find the kingpin allergen, if you like, plus a P88 or Cyrex 4 to find cross-reactive gluten foods and any with complement issues.

But, most importantly, I will advise a gut screen to check for clues to increased sensitivity – far more complex than leaky gut, note – and then work on whatever comes back which may be making the person become ever-more sensitive. It’s usually a combination of poor SIgA, SCFA and enzymes levels somewhere.

I will also consider neurological issues. For example, do we have a brain-gating problems or are neurons too close to threshold? Vascularly, is hypoxia, a lack of oxygenation a problem? Is there are really big issue at the heart of it like autoimmune gastritis?

So, yes, it’s complex and not just about food testing, but that does have a part to play. If you can find at least some of the key allergens, then you can reduce the impact on the body and encourage healing. And, if a person comes back with loads, you know it’s a loss of oral tolerance and the hunt then starts for why?!
