Do you have digestive issues, itching, rashes, throat swelling, sinus congestion, cough or difficulty breathing with certain foods? Noticing that you are becoming less tolerant of certain foods as you get older? Struggling with constipation, diarrhea, gas, bloating or chronic abdominal pain? Chances are you have food sensitivities due to a leaky gut not actual food allergies. Food allergy testing tests for foods that you have created an immune system reaction to and developed an immediate, IgE or delayed IgG reaction to. Doc J breaks down how food allergy testing is useful in determining the status of the gut lining barrier and if you have a leaky gut that has caused food sensitivities versus full on allergies.
