top 5 food intolerance tests

Have you been experiencing digestive issues, skin issues, or headaches lately?  If you are having these symptoms everyday, especially after you eat, then you might be experiencing symptoms caused by a food intolerance.  Food intolerances root from the body’s digestive system. When the body cannot tolerate certain food items, irritation in the digestive tract occurs because the foods cannot be broken down to complete digestion. This can then manifest into a large variety of symptoms. 

The "Gold Standard" of addressing these symptoms is the elimination diet.  The elimination diet is where you do not eat the foods you suspect that you are having issues with and then see how you feel.  You can then start introducing the food items back into your diet and see how your body reacts.  To do this on your own can be very time consuming to try to figure out what food items and ingredients might be causing you the issues.  

Food “sensitivity” tests are becoming very popular these days.  You can do these tests from the comfort of your own home.  No doctor visits and expensive co-payments!  These tests will provide you with a guideline or report of all the items that they tested against, and what you are reacting to.  However, not all tests are alike.

Some of these tests on the market use blood, hair, or saliva. While the term allergy, sensitivity, and intolerance are used interchangeably most of the time, what they are testing for are not alike at all.   

Let's take a look at some of the more important things you should know before you buy:

What are the first things you should look for when choosing a testing kit?

1) What exactly are they testing for?

There are four types of hypersensitivities that can be tested for:

Type I: is categorized as an allergy. This refers to an IgE reaction. An allergy is an immediate reaction that occurs when the body is triggered by an innocuous foreign substance. (this reaction can be the most severe but it only affects about 2% of the population). This involves the immune system.

Type II: is categorized as a cytotoxic reaction, or antibody dependent reaction. It refers to an IgM or in some cases, IgG. In this instance, an antibody binds to an antigen on the target cell which is actually a host cell that is perceived as foreign. This also involves the immune system.

Type III: is an immune complex and categorized as an IgG reaction. The antibody binds to an antigen forming a circulating immune complex. This also involves the immune system.

Type IV: is categorized as an intolerance, which is an antibody independent, cell mediated hypersensitivity. It does not involve antibodies, but instead involves T-cells attracting and activating macrophages and will cause an inflammatory response. There is a delayed reaction. This does not involve the immune system. This is what the majority of people suffer from.

2) How many items are they testing for?

The more the merrier! While a lot of items listed can be overwhelming, it is much easier to do an elimination plan properly when you know all the items you can be reacting to!

3) What collection method are they using?

The most common methods are hair, saliva, or blood.

4) How long will it take to get the testing results?

The average time will vary, but the typical response time is within a week.

5) How much does it cost?

The price will vary depending on how many items they test for and the method that they use. The average price range is between $80-$300.

The Food Intolerance assessment will compare your body’s electrical resonance to several food items within the categories of protein, grain, fruit, dairy, fat, seafood, spices, sweeteners, and beverages. For many people, some of these specific items can contribute to sensitivities or reactions in the gut and brain.

With the same technology, the Nutrition Imbalance assessments can indicate which vitamins, minerals, fatty acids, amino acids, and neurotransmitters are out of balance. These nutrition imbalances generally occur when your body has the inability to absorb certain nutrients.

How Accurate Are Food Sensitivity Tests?


When it comes to immune based sensitivities, there are many accredited labs that offer food sensitivity testing via a blood, hair, or saliva sample, with accuracy ratings of 95% or more.

A strict elimination diet is truly the only way to test for food intolerances with complete accuracy. While an elimination diet is considered the “Gold Standard,” it is extremely challenging for an individual to be disciplined in their food intake and control every aspect of their food sourcing. The amount of time required to conduct such a regimented diet can be very lengthy and costly, especially if the individual has no guidelines on how to determine potentially offending items. Using a 5Strands Affordable Testing kit, it removes the guesswork and makes an elimination diet easier by providing the exact list of items that should take priority in an elimination diet.

The accuracy of the results is directly related to the amount of interaction and diligence that is given implementing the results. Case studies have shown that when a customer adheres to the guideline the way it was intended, they have seen 100% accuracy and the symptoms disappeared when the symptoms arose due to a food intolerance.

In Summary:

If you have no idea what foods or environmental items might be triggering your symptoms, pick a test that aligns with your needs. The test you choose should encompass a wide variety of items tested at a cost that you are able to afford.
