This page about seafood and gout attacks – eating it lowers the risk of them - was last reviewed or updated on 14 January 2016.
On our fish oils for gout pages, which begin here, we state the case that fish and fish oil are anti-inflammatory and can help you deal with gout. So does the often repeated exhortation to eat fish for gout stack up with any scientific research on seafood and gout? It seems so. Research published in 2015 (1) showed that there is less risk of a gout attack if gout sufferers eat fatty fish. And the study was among gout sufferers.
However eating fatty fish does not mean you would never get a gout attack. That would be too much to hope.
But the study did conclude that, after adjusting for other gout flare triggers, the risk of an attack, if fish was eaten 48 hours before an attack, by those who had suffered them, fell 22-23%.
Which seafood were beneficial?
Fish eaten in the study were - anchovies, mackerel, salmon, sardines, cod, trout, herring, tuna, squid. All except squid are on our lists of the best fish for gout. Squid isn’t there because of contradictory numbers for its purines’ amount.
Not included in the study, but also on our best fish for gout tables were - real caviar, herring roe and oysters. Our best seafood for gout were - real caviar, herring and mackerel.
Many of our best fish for gout are high purine. The ranking is based on the least amount of created uric acid per the amount of omega -3 in 100 grams of fish. Another of our tables, possibly more relevant, compares uric acid created to EPA in fish (EPA is one of the omega 3’s. The other is DHA. EPA is the most anti-inflammatory one).
More science about seafood and gout
In one of the few really detailed studies of the effect of a diet on uric acid, and gout flares in gout sufferers (3), gout attacks fell about 70% and serum (blood) uric acid fell by a useful amount. Uric acid normalised in 7 of the 12 patients with a raised level at the start of the trial. Fish was eaten at least four times a week and this fish may have been among the reasons why uric acid fell and normalised, as did gout flares.
OMEGA 3: OMEGA 6 RATIO – DOES MORE OMEGA -3 REDUCE THE POSSIBILITY THAT SEAFOOD CAUSES GOUT ATTACKS ?
The study that learnt gout flare risk fell 22-23% found another reason for eating more omega – 3 to reduce the risk of gout flares. On our fish oils for gout page we discuss the importance of boosting the omega 3 you eat whilst reducing your omega -6 intake. This study also came to this conclusion. There was a higher risk of gout attacks when more omega -6 to omega -3 was eaten But less risk when more omega -3 was eaten.
Could it be that eating more
omega -3 reduces the possibility that purines in fish trigger gout or raise
uric acid, or both? That high purine fish are not as risky as is thought ? Maybe. But still be
careful of eating too much high purine seafood.
WHY DOES FISH HAVE AN ANTI INFLAMMATORY EFFECT?
Science is tracking down why fish and fish oil are anti-inflammatory in gout and other inflammatory diseases. Many of the fish that reduced the risk of gout are high purine. But something else in the fish seemed to be more important. As mentioned above this could have been the omega -3.
It is scientifically believed that gout attacks’ inflammation is driven by the NLRP3 inflammasome, which activates the Interleukin-1b (IL-1b) inflammatory cytokine when gout’s MSU crystals form. The consequent inflammation of the attacked joint, and its surroundings, is caused when IL-1b secretes. Amazingly, Omega 3 fatty acids (mainly EPA and DHA and especially EPA in fish and their oils) limit IL -1b. This amelioration is most used anti-inflammatory route, but studies have found others too, even by DHA as well as EPA.
WHAT ABOUT FISH OIL FOR GOUT ?
Fish oil did not affect gout attacks in this study. But there were insufficient respondents supplementing with fish oil to reach any definite conclusion. We think fish oil is beneficient against gout attacks. It is very important to take high quality fish oil, just as high quality (black) tea, but not ordinary tea, may be positive against hyperuricemia (high uric acid) too. After all, fish oil contains the positive omega fatty acids.
