Why eat mackerel?
- One serving comfortably exceeds a week's recommended omega-3.
- Several times a day's B12 in one fillet.
- Smoked and tinned versions need no cooking.
How to include it
- Grill fillets skin-side up until the skin blisters.
- Flake smoked mackerel through a potato and watercress salad.
- Pâté it with Greek yogurt, horseradish and lemon.
Things to consider
- King mackerel is high in mercury; Atlantic mackerel is not — they are different fish.
- Smoked mackerel can be high in salt.
