So much chronic unwellness can be attributed to gluten sensitivity and to leaky gut syndrome. I have written on both of these subjects before. Fatigue, pain, brain fog, depression, digestive symptoms, asthma, kidney disease, sore tongue, and vitamin D deficiency are a sample of the hundreds of possible manifestations of gluten sensitivity, which can affect any part of the body. What's new is the single blood test that checks for both gluten sensitivity and leaky gut syndrome with unsurpassed accuracy and economy.
