Food intolerance(IgG) and food allergen(IgE) testing provide significant clarity to symptoms caused by food reactions. The newest advancement in discovering diet based reactions now includes the Vibrant Additives Test which evaluates 57 common additives as found in many new health foods. Testing for food additives compliments food allergy testing and measures IgG and IgA sensitivity to food additives, which produce histamine type reactions. Symptoms of food additive reactions are similar to many food reactions and include: Gas and bloating, fatigue, abdominal pain and cramping, diarrhea or constipation, headaches, brain fog, rashes or eczema, nausea, urticaria, bronchitis and asthma-like symptoms, joint pain, muscle stiffness, nerve tingling and numbness. Food additive testing categories include food dyes and pigments, pesticides, sweeteners, elements, preservatives and antioxidants, emulsifiers and surfactants, flavor enhancers, gums and thickening agents, and fibrous additives.
