If you experience bloating, indigestion, water retention, headaches, weight gain and skin conditions (such as eczema), this could be a sign that you have food sensitivities. The underlying cause of food sensitivities is poor digestion from stress, eating too much of a specific food, drinking lots of fluids with our meals, eating on the go and certain medications. The improperly digested food molecules pass through the digestive tract, triggering inflammation of the intestinal lining and an immune response. Comprehensive IgG and IgA allergy testing and individualized nutrition plans from naturopaths can help identify and treat food sensitivities.
