Is grouper high in fructose?

Watch for

• Ciguatera is the risk that separates grouper from ordinary whitefish.Ciguatoxin builds up through reef algae into the predators that feed there, and grouper sits high in that chain. Reactions can include vomiting and diarrhoea followed by tingling, joint pain and a reversed sense of hot and cold that lingers for weeks. Cooking, freezing, curing and smoking do not destroy the toxin, and the fish tastes normal
• Mercury tracks with size and age, so a big old grouper carries more than a small one.US federal advice places grouper in the once-a-week tier rather than the eat-often tier, which matters most in pregnancy and for young children
• Species substitution is well documented.Oceana DNA testing found king mackerel, a high-mercury fish on the federal avoid list, being sold as grouper, alongside farmed pangasius, perch and bream. If you are tracking reactions, an unreliable label makes the log unreliable too
• Moderate on histamine, histamine liberation and tyramine (all B), which is fine for most people but means grouper is a fresh-only item during a strict low-histamine elimination phase.Much of the grouper sold in the US is imported and previously frozen, so handling after thawing is what counts
• Grouper is overwhelmingly a restaurant fish: blackened, in a sandwich, or fried.The paprika and cayenne in a blackening rub are nightshades, the batter is wheat, and the tartare or remoulade alongside it is a bigger trigger load than the fish
