||This was not reduced by an olive oil
(monounsaturated fat) diet. It was reduced some 70% in rats fed safflower
seed oil. But the group receiving tuna fish oil (rich in n-3 PUFAs) had no
arrhythmic deaths. These investigators also reported a similar
antiarrhythmic action of the n-3 PUFAs in nonhuman primates. Since then
others have repeated their findings in rats. When we learned about their
results, I realized their findings were potentially very important, so we
decided to see if we could confirm their surprising findings.
