I actually was in the same boat...for years, I thought I was lactose and gluten intolerant..and have had several tests that all said I was not either! But I was still not convinced - until recently when I took a food sensitivity test and found out, 19 out of 96 foods they tested cause inflammation in my body ( blood test for IgG levels.) Most of the foods were a staple in my daily diet and foods that were considered healthy. If you are interested, I'd be happy to share the company that I used - it's a test you can do at home and send in. Good luck!
