Gout is a form of arthritis and is associated with high-blood-levels of uric acid, a compound that's a by-product of your body's normal breakdown of food. Uric acid itself is a product of the metabolism of purines, compounds found in a range of food.
Foods containing purines;
- Offal (including related products like pate)
- Game meat
- Some seafood (especially anchovies and sardines)
- Some vegetables including asparagus and mushrooms
Normally your body maintains uric acid levels by dissolving it in the bloodstream, filtering it through the kidneys and then urinating. If you start creating too much uric acid or other factors prevent your body dealing with the load, then uric acid crystals form on the joints. This is what causes the sudden pain, redness and swelling of gout.
