In this episode of Ask the Health Expert, JJ answers Maddie’s Facebook question, “What is the most accurate test for food allergies?” You’ll learn what separates a true food allergy from food intolerance, JJ’s favorite food sensitivity test, what testing ultimately reveals, what you should do before you test, signs and symptoms of food intolerance, the top foods that people respond to (which led JJ to write The Virgin Diet), and what doesn’t always show up on testing that can contribute to gut permeability. Plus, JJ reveals what makes your gut leaky (it’s not just food!), the right nutrients to help heal your gut, how long you should wait before you rechallenge a particular food, and the limitations of testing. If you’re curious about food intolerance and how testing and/ or elimination diets can help you, you’ll want to tune into this short, informative episode!
