Many people are suffering from health issues that are a direct result of the foods they are eating. They know, or highly suspect certain foods are playing a role… the only problem is that they don’t know which foods to reduce or completely remove from their diet. Maybe you have been trying to figure out which foods you should be eating and which foods you should avoid. Trying to sort this out on your own can become complicated and frustrating for several reasons:

  1. Doctors and diet experts can’t seem to agree on WHAT or HOW we should be eating. Paleo, AIP, low-FODMAP, ketogenic, intermittent fasting, several small meals per day, plant-based, low-fat, high-fat and high-protein, raw foods diet…on and on…
  2. There are so many different diet plans being promoted today as “healthy” yet they often contradict one another???
  3. Maybe you have tried some of these diets, but you did not see the results you had hoped for.

No Wonder People Are Confused!

Food Sensitivity Testing

This is where food sensitivity testing or food allergy testing come in. This is a functional medicine approach to establishing a diet plan that is suited to your unique dietary needs. This type of testing helps determine how your immune system is responding to foods in your diet. You might be wondering why we want to know this…how this information helps. Let’s keep this simple…we don’t need to make this complicated with a bunch of medical terms and details.

  1. Most of your entire immune system is located in and around your digestive tract.
  2. The main “intruder” that your immune system is dealing with on a daily basis is the food you eat (constantly deciding if it is a friend or foe).
  3. The primary goal of most diet plans today is to reduce inflammation; your immune system causes most of this inflammation.

With the help of a functional medicine doctor who understands HOW to interpret these tests, you can get started on a diet that will work with your body and not against it. Notice I said “HOW” to use these tests. I have seen countless patients in my Naperville office that have had food testing done, followed the prescribed diet and did not get good results. Or they had food allergy testing, and everything came back negative…meaning they “had no food allergies. “Your doctor needs to understand HOW to interpret these tests. I have used this type testing for over 15 years now it is very effective when the results are understood and implemented properly. What you DO NOT do is simply avoid the foods that came up positive. You are missing the big picture when you do this! Your doctor needs to be able to see which foods are positive, understand how these foods are related and have enough clinical experience to create a diet plan based on the test results. You need to create a diet plan BASED on the test result…not a diet plan that IS the result. Your doctor must understand the relationship between the positive foods, how they are related / not related and how these foods are causing your health issues. In the right hands, food sensitivity and food allergy testing can very useful.

Food Testing is NOT Accurate?

There are critics who say that food testing is either not accurate or not useful. My response to them would be that they lack an understanding of what they are looking at. To these people, the results seem random, cannot be explained or are not reproducible later.  I would agree with them that food test results in the hands of inexperienced doctors is USELESS because the recommendations they give their patients probably won’t work. It is true that your food test results will not tell you exactly what to eat and what not to eat…but that is not their purpose. The testing provides information about your immune system’s response to foods in your diet. This information is then evaluated and used to create a comprehensive dietary plan; I will say it again; create a diet plan BASED on the results. This can only be accomplished when the doctor reading the results understands what they are looking at.

This all goes back to the functional medicine approach…find out what is out of balance and get it balanced again. You must take several factors into account when creating a diet plan and food testing a very useful tool in the hands of an experienced practitioner.

If your doctor has enough information about how your body is functioning and if they know what to do with it; your chances of success increase dramatically.

I wish you success in your quest for better health!
