Diet: Avoid foods and beverages that stress the adrenals, especially sugar, alcohol, caffeine, tobacco, fried foods, processed foods, pork, sugar, and refined carbohydrates. A high percentage of symptomatic individuals are also allergic to gluten (wheat, spelt, rye, barley, oats) and casein (dairy products) and should avoid these foods altogether. Various forms of the Paleo diet are ideal for adrenal insufficiency. Unless allergic to them, eat more fresh fruits and green leafy vegetables, along with garlic, onions, shiitake or maitake mushrooms, olives, and legumes. Avoid fish and seafood due to their high mercury and other toxin content.
