might be worth dropping the wheat for a couple weeks to see what happens.
I think this might be a wheat sensitivity, but I'm worried I might just be jumping on the "wheat is evil" bandwagon.
Though not nearly as common, Sesame Seeds, particularly the paste (tahini) or the oil is a very inflammatory food as well.
Soybean oil and canola oils seem to be the most common chronic inflammatory foods.
I highly recommend the coconut oil, as well as high quality organic virgin olive oil.
In my own life, i replaced soybean and canola oil with coconut oil. And added lots of turmeric, ginger, and garlic.
