In addition to nobodys posts I’d just like to point out a few things.
You need to look at the macro side of this and not just the micro side. People become obsessed with food and their intake of it. It all becomes about purines, sugars, salts, etc. Whilst minimising most of these ingredients will help with reducing uric acid levels you need to also look at the bigger picture which is they will not solve your Uric Acid Arthritis (gout) issue.
Allopurinol, Febuxostat and a few drugs are there for this very reason. What many people overlook when starting these medications is that they are not just there to ‘reduce uric acid’ they are also there to ‘psychologically hold your hand’ whilst you get on with life which means going on holiday, eating what you like, doing the job you like, doing the sports you like, etc.
Now that doesn’t mean you have to take these drugs for the rest of your life as there are medication breaks, take a read of this.
When choosing food, keep a logical approach but also keep an open mind to life.
