Here is my experience on this subject. Starting with excerpts:
Rheumatoid arthritis and gout are two different types of arthritis. They may have some symptoms in common, but they have different causes and require different treatment plans.
Some 3 or 4 years ago, I started to have pains in my joints, including my right big toe. Doctor visit, given some medication. Took that for a few days. And then I thought of finding what was causing tat in me, what I was eating that caused that.
So I thought about milk, then sugar. Sugar came out as a probable cause. So I went to all restaurants and asked if they had food with no sugar. It does not seem to exist, of if so, difficult to find in Thailand. All food is laced with refined sugar, or contains a bottled sauce from stores, that contains some 20% of refined sugar.
I asked many restaurants if they had food with no sugar. Then i realized that nobody reads what is inside the bottled sauces that they buy. One lady told me that there was no sugar in her Pad Thai. So I asked what was in the red sauce in her pad Thai. She answered 'Ketchup'. No kidding.
So I stopped eating Thai food, entirely. I do my own cooking.
No refined sugar in my apartment, and no bottled sauce, except for Kikkoman sauce, Sesame sauce.
All my pains disappeared quickly.
And I found that sugars from fruit is no problem.

7 Gout Symptoms You Might Be Ignoring
Pain in your big toe. ...
Pain in your knees, ankles, wrists, and/or elbows. .."
"
The top 10 foods and drinks that trigger gout are:
Sugary drinks and sweets. ...
High fructose corn syrup. ...
Alcohol. ...
Organ meats. ...
Game meats. ...
Certain seafood, including herring, scallops, mussels, codfish, tuna, trout and haddock.
Red meats, including beef, lamb pork and bacon.
Turkey."
So obviously, since the list is quite extensive, certainly that any food in excess will cause problems.
But notice the one on top of the list, Sugars.
If one eats Thai food, it is impossible to not eat the bad sugar, refined sugar, in excess.
