An Elimination Diet is exactly what it sounds like - a diet that eliminates certain foods that could potentially be causing a problem in your body - the most common offenders being gluten, dairy, eggs, corn, and soy, and sometimes nuts or even nightshade vegetables like tomatoes and peppers. These foods are eliminated from the diet for a period of time with hopes that your body “resets” and becomes less reactive. The foods are then re-introduced gradually as you observe for any negative responses, like headaches, brain fog, digestive complaints, and more (discussed below).
