Here are some websites for general and exhaustive lists of gluten-containing and gluten-free foods.
The bottom line: real whole foods (meat, eggs, fruit, veggies, nuts, and dairy if you drink it) won’t have gluten in it. Most processed foods: breads, cereals, soups, on-the-go-bars, etc. do. Anything with wheat, rye, barley, and their derivatives do.

Pull the gluten out for 30 days and see what happens. There’s an international pledge for January called Gluten-Free January. Sign up and get the wonderful tips and tricks emailed to your inbox weekly.
If you remove gluten-only and do not see results, I strongly suggest removing all rice, beans, peanuts, and lentils. All of these foods have common ingredients that are particularly inflammatory in the intestines!
Good luck and let me know how it goes!
