Some articles on the link between weight and PsA

I'm following up on a discussion started in general about the potential link between PsA and obesity. I am convinced from my own experience (and the research of Dr. Sears, the Zone diet guy) that what you eat DOES have the potential to increase or decrease inflammation in the body. However, these articles suggest there may be a stronger link between the two.

Thanks for showing me the way, Seenie!
