Did you know that you could be allergic to the foods you most commonly eat? Many people try a diet for health and weight loss purposes, but find themselves still unwell or overweight. The culprit may be your delayed food allergies.

There is much confusion surrounding the topic of delayed food allergies. People often mistake them for food allergies that cause an immediate reaction, however these are referred to as Immunoglobulin E (IgE) antibodies. An IgE allergy could be caused by a food which causes an immediate severe reaction or even anaphylactic shock. A delayed food allergy is referred to as Immunoglobulin G (IgG) and its symptoms are more sneaky. IgG antigens have a half life of 21-28 days in the blood, hence the name delayed food allergy. For many, symptoms can appear as:

  • Chronic nasal congestion and drainage
  • Fatigue after meals
  • Gas
  • Dry Cough
  • Sneezing
  • Black circles under the eyes
  • Ear infections
  • Migraines
  • Diarrhea
  • Itchy eyes
  • Chronic headaches
  • Watery eyes
  • Itchy skin
  • Keratinosis pilaris
  • Rash
  • Ear popping

To get your delayed food allergies tested, your doctor will need to order an IgG panel from a reputable lab. It’s a simple blood draw and it will take anywhere from 2-4 weeks to get your results.

How to read your results:

  • The different foods your blood was tested with will be listed and the report will give you a +1 to +5 key on which the food measures. +1 is the least reactive while +5 is the most.
  • Any foods that are measured a +3 or above should be avoided completely for at least 3 months. After you have cut them out of your diet for that long, you can slowly try re-introducing, but only as an indulgence or 1-2 times a month.
  • Foods that measure +1 to +2 are typically foods that you eat frequently, try cutting them back by at least half.

If you suffer from chronic conditions, especially gastric and inflammation related, you will find that cutting the foods that you are reactive to out of your diet will make a significant difference. People are typically very reactive to wheat, gluten, cow’s milk, eggs, soy and yeast, but never know, you could be extremely reactive to something as unassuming as pineapple or asparagus. By cutting these foods out, you are giving your body’s immune response a chance to heal and it creates a domino effect in the other areas you may be having trouble in such as skin, digestion, hormonal balance and so on. Consult with your practitioner, but we highly suggest you explore your delayed food allergies to set you on a better and well-informed path to wellness.
