#10 – The Future of Food Sensitivity Testing, Curing IBS, Rethinking Gluten Free Diets, and the Genetics of Coffee Metabolism with Dr. Joel Evans, M.D.

Food sensitivity testing is a controversial topic. Even among our team here at Gene Food there is disagreement, with some doubting the science behind the standard IgG panels and others swearing by them as an essential tool for healing autoimmune disease. However, debates notwithstanding, there can be no doubt that most IgG food tests on the market today register false positives with the result being overwhelmed consumers staring at a list of 20-30 foods that are now “off limits.” Our guest today is hoping to help change all that by making food sensitivity testing more accurate. Joel Evans, M.D. is one of the leaders of the integrative health movement. He is a board certified OB/GYN and international lecturer, is the Founder and Director of The Center for Functional Medicine, where he practices integrative functional gynecology.

Dr. Evans was honored to speak at the United Nations in March 2013 on the topic of Prenatal Origins of Violence, and he now serves as UN Representative and Chief Medical Advisor for OMAEP – World Organization of Prenatal Education Associations. In addition to his integrative practice, Dr. Evans serves as medical director for KBMO Diagnostics, a company that is producing the 2.0 version of IgG food sensitivity tests. KBMO has introduced new technology aimed at not only finding foods that register an IgG response, but that also cause inflammation which can damage gut health. In today’s episode, we learn about the new scientific developments aimed at increasing the reliability of IgG tests, we discuss a promising study Dr. Evans did on patients with IBS, when gluten free diets aren’t necessary, the health benefits of coffee, how food sensitivity can affect the development of our children and much more.

This Episode Covers:

  • Traditional food sensitivity tests and false positives [7:00];
  • Zonulin and when intestinal permeability is a good thing [10:55];
  • IBS discussion [13:30];
  • Who needs to be on a gluten free diet? [21:30];

The “I did great with gluten in Europe” story could be linked to the glyphosate that is so prevalent in American foods.

I did a blog previously on some of the tests that are used to identify gluten sensitivity.

More on glutathione and superoxide dismutase. Dr. Evans also mentioned MTHFR and COMT.

My blog on urine PH and how that metric changes with diet as well as more on coffee metabolism.

    Thank you SO MUCH for this podcast. I’m looking into ordering the FIT test through a nutritionist in Massachusetts and I’m really excited to work on some of these food sensitivities I’ve had for years now.. migraines, etc. This was super helpful! keep up the great work.
