Mackerel (smoked)

Why mackerel (smoked) is rated low

Smoked mackerel is low FODMAP. Plain smoked mackerel is fish, salt and smoke: protein and oil with essentially no carbohydrate, so there is nothing in the fish itself for a FODMAP load to come from. The rating is estimated from what it is made of rather than from a measured serving, and it holds at Any typical portion. The catch is never the mackerel. It is what gets added to it: a glaze, a seasoning rub, a pâté base, or the bread and sauce it is served with.

What changes your risk

• Glazes and coatings Peppered fillets are usually just fish and pepper, but sweet chilli, honey or barbecue style glazes can bring honey, garlic powder or onion powder along. Read the ingredient list on every pack.
• Pâté and spreads Smoked mackerel pâté is usually blended with cream cheese, soft cheese or cream, and sometimes onion, which makes it a different food from the plain fillet.
• Canned and marinated versions Mackerel canned in tomato sauce or sold in a marinade often lists onion or garlic. Mackerel in plain oil or brine is the closer match to the smoked fillet.
• The rest of the plate Because the fish adds nothing to the total, the FODMAP load of the meal comes entirely from what sits beside it: rye crispbread, a creamy bought dressing, a pickled onion garnish. Count those, not the mackerel.

What else works

Other plain fish behave the same way: smoked salmon, smoked trout, fresh mackerel, and sardines or tuna canned in plain oil or brine are all low when nothing has been added, and eggs fill the same protein role. The lookalikes to watch are the ones that sound like plain fish but are really a recipe: smoked mackerel pâté made with cream cheese, mackerel in tomato or onion sauce, fish cakes bound with ordinary wheat breadcrumbs, and anything sold with a honey glaze. For a creamy element, a dressing of lactose-free yoghurt and chives does the job a soft cheese pâté would.

How to keep it low

Buy fillets whose ingredient list reads mackerel and salt, or mackerel, salt and pepper, and leave anything with a long list on the shelf. Once opened, keep it wrapped in the fridge and use it by the date on the pack. Flake it straight over rice, boiled potatoes or a salad of baby spinach, cucumber and bell pepper, and dress it with garlic-infused oil and chives instead of a bought dressing. If you want it on toast, gluten free bread or traditional sourdough spelt bread keeps the base in line with the fish.
