Food Sensitivity and Intolerance Testing (IgG)

Modern times see the composition of our food constantly changing. As nutrient content of our soils change and agricultural practices slowly influence the chemical structure of what we are eating, a trend is emerging that shows a rise in food based sensitivities that may encroach on the quality of our day both physically and mentally. In fact, food sensitivities are now considered  a major causative factor in disease.

Senior Naturopathic Physician, Dr Benita Perch explains, "I see many clients, both adults and children, who find that when they move to Hong Kong all sorts of symptoms start to appear and wonder why this is."

"Air pollution, antibiotic use and other environmental factors can add an accumulated functional load on the liver that inhibits the organ’s ability to manage the complex relationship between the immune system and the food we eat. This can then lead to a low grade form of inflammation that then shows up in many different ways from the more obvious digestive disorders such as irritable bowel and bloating to issues such as eczema, asthma, joint pain, headaches and poor concentration."

Could the foods you eat on a daily basis be a sustaining or even a causative factor in your health condition?

Immediate food allergies (e.g. allergies to nuts or shellfish) are generally obvious and equally as dangerous with hospitalisation necessary in some cases. This involves a specific immune response mediated by IgE immune cells. Swelling, itching and even life-threatening symptoms such as asphyxiation can occur as a result of food allergies.

Food sensitivity (also known as food intolerance) is a more common form of immune response, mediated by the IgG immune cell. In contrast to the fast-acting IgE histamine response, this is a delayed response from food exposure that can last for up to 72 hours. The IgG response is often linked to chronic disease conditions such as fibromyalgia, eczema, asthma, arthritic pain, IBS, chronic fatigue and even depression and hyperactivity. Symptoms that can occur with no clear explanation include abdominal bloating and distension, brain fog, inflamed joints, and fatigue to name a few.

A simple test, yet a useful and potentially life-changing guide

Fortunately a dried blood spot exam is available at IMI to help accurately identify the problem foods that can cause IgG or delayed immune responses.

With samples drawn onsite by one of our professionally trained IMI staff members, our IgG testing package includes a detailed report of 93 foods tested, and the significance of how the foods may have contributed to your physical or mental symptoms. The results are interpreted by one of our experienced natural medicine practitioners for one inclusive fee, saving you the further cost of a full consultation. This targeted consultation allows you greater insight into how your diet and environment might be affecting the quality of your health and how some simple changes based on the results can make all the difference.
