"I personally use and trust the ALCAT Food Sensitivity Test for my own health.  It has been a valuable resource tool throughout my Hashimoto's and Celiac journey.  I recommend it to all my clients and I know it will be valuable information for you too."

Are foods making you sick?  Inflammation and chronic activation of the immune system due to food intolerance issues has been linked to an array of health issues including autoimmune & thyroid conditions, diabetes, digestive disorders, migraines, obesity, chronic fatigue, ADD/ADHD, joint pain, arthritis, and many more.




ALCAT is not testing for food allergies; instead, the test helps to identify food intolerance issues, which are far more common and generally take longer to show up than do food allergies.  The ALCAT test is the most effective food intolerance test available, identifying your cellular reactions to over 350 different foods, chemicals, food additives, functional foods, herbs, and mold.  Using the results of this test, we can identify the root causes of symptoms and chronic health issues you may be experiencing, helping you to avoid exposure to sources of negative symptoms and reactions to foods that are triggering even low level inflammation in your body.

The ALCAT Test is more effective than standard Immunoglobulin G (IgG) testing because they rely exclusively on one immune pathway: serum levels of IgG.  High food specific IgG titers are indicative only of exposure, not necessarily of intolerance.  Therefore, high frequency of consumption or overexposure may lead to false positive test results.

What is food sensitivity?

The inability to tolerate foods and environmental factors, also known as sensitivity or intolerance, induces chronic activation of the innate immune system and gives rise to inflammatory processes, which includes excess production of reactive oxygen species and the release of preformed and newly synthesized mediators of inflammation.

This inflammation has been linked to countless chronic conditions, including: digestive disorders, migraines, obesity, chronic fatigue, ADD, aching joints, skin disorders, arthritis and many more.

How does food sensitivity differ from classic food allergies?

True food allergies refer to foods that trigger the immune system to acutely produce massive amounts of the chemical histamine that leads to anaphylaxis. This potentially fatal condition causes the throat and esophagus to swell, cutting off air from the lungs, or may simply cause hives, skin rashes, and other non-life-threatening reactions.

This type of reaction is called a type I hypersensitivity reaction, caused by the degranulation of mast cells or basophils that is mediated by Immunoglobulin E (IgE).

Bottom line: This test gives you a huge head start in your healing process. Even in the rare event that you have no food sensitivities, you will know for sure that you don't and can stop wasting your time and effort wondering if food and chemical sensitivities are contributing to your problems.
