I went through this with my dad when he was diagnosed with "gout". Limiting purine intake is the key.
Purine is found in whole gains, protiens and a myriad of other "good for you foods". The list of foods to avoid and foods that were okay that he was given were a laugh but it was 15 years ago. Don't eat whole grains (i.e. whole wheat bread etc), do eat jello. Don't eat meat drippings and gravies, do eat lettuce. Fortunately we found some terrific info on the internet and eventually developed a plan. We took him off of all the foods loaded with purine ( like soups - which usually have a base made from meat broths, and any gravies or sauces that had meat broths involved) for three months to clear out his system. We even cooked his meat above the heat so that the fat would drain off which is where the protien purine is usually found. Then we began adding them back in one by one - the very day he ate mushrooms which he adored, his uric acid sky rocketed and his gout flared up for a week. Never had an issue after he stopped eating them. But this was just his personal reaction.
Good luck to you. Try surfing for articles on "purine" and you should find some wonderful resources.
