I like how you linked to an article on the Huffington Post. Very reassuring.
Prostaglandins are not "inflammatory chemicals". Prostaglandin is a hormone. There are different types prostaglandin and they cause a huge variety of responses (not just inflammation, some do they exact opposite).
You're correct about everything you've said. And so was I. What's your point? I do honestly apologize for my use of "chemical" and not "hormone"... it's not like hormones are made up of cheica... er, wait? Chemicals -> lipids -> Prostaglandins. Chemicals are not lipids or prostaglandins but both the latter are chemicals. Correct, they can be anti-inflammatory as well. Guess which are more present after gluten consumption? Well obvious troll... it's been fun. We should pick this up again later... I've got a few miles to do.
