My mother suffers from sever arthritis and has done so for many years, my mother in law suffers from fibromyalgie which is a very strange illness vaguely related to arthritis, so i was interested to read the article. I hope this will help you, a lot of people presume curries are bad for your health, and the amount of fat probably doesnt help, but i usually feel pretty damn good after a curry and all those strange and exotic spices must be doing something!
A lot of stuff that makes us healthy is stuff we dont wanna eat, nice to see something that we already like, doing something positive instead of negative.
