Functional Testing
Food Sensitivities, Intestinal Permeability "Leaky Gut" and Candida Testing

Functional Testing

MellyFit Nutrition offers three different types of Functional Tests to determine issues related to food sensitivities, digestive, and gut health.  You can order the the tests directly from our website and once the results are ready, we will book a 30 minutes consult to review the results, answer questions and provide recommendations.

IgG Food Sensitivities Test

Who is this test for?

Food isn’t an easy topic to discuss when it comes to our health and wellness. What goes down easily for some might be, well, sensitive for others. Using FLUIDS iQ’s highly sensitive analytical tests measure the levels of IgG antibody reaction to very specific food ‘antigens’, thereby offering up an opportunity to learn something about how our bodies react to certain foods and food groups. We think that’s something everybody can benefit from, regardless of age.

There’s lots of talk and a whole bunch of confusion on this topic. But let’s be clear: Food sensitivity is an abnormal immune reaction to certain foods, with symptoms generally limited to the intestine, a.k.a. “the gut.” Basically, the kind of stuff that leads to too many (or too little) bathroom visits. This distinguishes it, completely, from food allergy, which may cause a multitude of body responses including severe, life threatening, allergic reactions (anaphylaxis). Our FLUIDS iQ tests for food sensitivities and not food allergies.

The Food Sensitivity test can tell us 90% or more of the story. Food sensitivity is an analytical wellness test through a functional lens. Food, no matter what kind, require enzymes to break them down into the components our body needs to digest them and benefit from their nutrients. And based on where our body breaks down specific food groups, there are particular enzymes it uses for that purpose. Whether it’s proteins, fats or carbs, there’s an enzyme for that, and food sensitivity testing can be a helpful tool in assessing enzymatic imbalances.

Who is This Test For?

Although the term “Leaky Gut” has been used for years to describe all manner of issues relating to how people feel, it’s only recently that the scientific community discovered that there’s actually a biomarker in our body that, together with its related family of peptides, controls the tight junctions of our gut so that, to put it bluntly: The good stuff goes into our bloodstream and the bad stuff stays out. Everyone is affected by it to one degree or another. It’s called Zonulin and it’s revolutionary.

Using The FLUIDS iQ test for intestinal permeability (“Leaky Gut”), measures levels of Zonulin and its related family of peptides (Zonulin FP)

Zonulin (pre-Haptoglobin 2) is a protein that modulates the permeability of tight junctions between cells of the digestive tract wall. Zonulin, and its family of peptides, are found within intestinal cells and, interestingly, its production and release mimic the effect of certain bacterial toxins. Once triggered, Zonulin plays an important role in the creation of what we think of as gut “leakiness.”
The takeaway? The gliadin-Zonulin “leak” effect occurs not just in people with celiac disease or gluten-sensitivity. It occurs in everyone, but the effect is longer and more pronounced in the intestinal cells of people with celiac disease.

Candida Test

Who is This Test For?

Candida albicans is a yeast found in the mouth, on the skin and, you guessed it, also in the gut. While it generally lives in harmony with other organisms in our microbiome, sometimes there’s an overgrowth, which can lead to one of the most common fungal infections in humans.
The FLUIDS iQ Candida Suite test, which measures the levels of IgM, IgG and IgA antibodies,

Candida albicans is a yeast that is normally found in small amounts in the body, and is the only fungal species belonging to our ‘normal’ microflora. Candidiasi is a fungal infection caused by an overgrowth of yeasts that belong to the Candida family, with Candida albicans being the most prominent. In Candidiasis, Candida albicans can infect areas such as the skin, genitals, mouth, respiratory tract and also the gut. In response, our immune system produces antibodies, which are known as IgM, IgG and IgA.
