Immediate food allergy involves foods that are rarely eaten. Unfortunately, delayed food allergy involves commonly eaten foods, foods that you eat every day and may even crave. When people quit eating foods that cause immediate symptoms, they have no withdrawal or detoxification symptoms. They don't crave or miss these foods. Powerful addictive cravings and disabling withdrawal symptoms are reported in over 30 percent of delayed food allergy patients when they stop eating food.
Immediate food allergens primarily affect the skin, airway and the digestive tract.
Virtually any tissue, organ or system of the body can be affected by delayed food allergy. This includes the brain, joints, muscles, hormone-producing glands, lungs, kidneys, and nervous system. In fact, delayed-onset food allergy is linked to over 100 medical conditions involving every single part of the body and some 100 different allergic symptoms. Immediate-onset food allergies are frequently permanent and fixed allergies. Once you develop an allergy to peanuts or shellfish, for example, it's for life.
