Melissa Watts, MD, an allergist and immunologist, joins the show to discuss at-home food sensitivity tests and their potential drawbacks and limitations. These tests are not based on scientific evidence and are inaccurate, often checking for a memory antibody rather than an allergic antibody. Dr. Watts warns that the use of these tests can lead to harmful effects, including a delay in accurate diagnosis and restrictive diets that can lead to increased anxiety and malnutrition.
