[Margaret Pilkington]

gout used to be thought of as a 'toffs' disease.
The toffs ate wild game,venison, partridge, pheasant, offal(kidneys for breakfast) and seafood, lobster mussels crab etc......all these are rich in purines...which causes the uric acid crystals to be deposited in joints.
The cartoons used to show the lord of the manor with his foot on a stool heavily bandaged suffering great pain.

I'm not sure that port is rich in purines, but I am happy to be educated if someone else knows better.
