Found a good article. This one actually includes some hard numbers for once on how much purines were consumed which can help us gout sufferers to know what our own limits might be.
Meat, seafood and other foods rich in compounds called purines are associated with a fivefold increased risk of immediate gout flare-ups, a new study shows.
Gout is a form of arthritis that often first occurs in the big toe. Anecdotal evidence has suggested that purine-rich foods can trigger gout attacks, but it hasn't been clear whether they cause immediate attacks.
The study included more than 600 patients with gout, most of whom were men and who had an average age of 54. The patients were followed for a year. During that time, the patients had a total of nearly 1,250 gout attacks, most of which occurred in the toe joints, said Dr. Yuqing Zhang and colleagues at the Boston University School of Medicine.
The average amount of dietary purines consumed during a two-day period without gout attacks was 1.66 grams, compared with 2.03 grams in the two days before an attack, according to a journal news release. Patients in the top 20 percent of purine consumption were nearly five times more likely to have a gout flare-up than those in the bottom 20 percent.
