Who is this for?

Retirement shoppers comparing fat figures

If you want frozen fish for lower-fat meals, the nutrition panel tells you more than a name such as ‘fish fillet’. Compare plain white-fish products per 100g, noting whether the figure is for fish as sold or prepared.

Households planning regular fish meals

Frozen portions can fit a weekly meal plan. The NHS recommends two portions of fish a week, including one oily-fish portion, so the lowest-fat option need not be the choice for every fish meal.

Shoppers who need straightforward preparation

If cooking methods, freezer space or portion sizes affect what you buy, check the pack weight and instructions. Read the allergen information and bone warning even when a product is described as boneless.

What should you check?

Choose the type of fish for the meals you are planning, then compare labels on a like-for-like basis and check whether the portions and cooking method work for you.

PriorityWhat to checkYour needs
Fat contentCompare fat per 100g and whether figures describe fish as sold or prepared. Check for batter, breadcrumbs or sauce rather than judging by the fish species alone.I want a plain fish option for meals where reducing fat is the main consideration.
Fish varietyDistinguish white fish from oily fish. The NHS recommends two fish portions a week, including one oily-fish portion.My weekly fish meals need to include more than the lowest-fat type.
Preparation and portionsCheck net weight, portion count and whether the stated appliance method starts from frozen or requires thawing. Follow that product’s storage and cooking instructions.Will the portions fit my freezer and meal routine, and can I use the cooking method on the pack?
Allergens and bonesRead the current ingredients and allergen statement, particularly on coated fish. Check any residual-bone warning, including on products labelled boneless.I need to know what is in each pack and take care when serving fish that may contain bones.

Common buying pitfalls

  • Assuming all cod products have a similar fat figure

    Sainsbury’s lists less than 0.5g fat per 100g for its plain cod fillets; a Young’s battered cod product lists 16.2g per 100g oven-baked. Those preparation bases also need checking before making a direct comparison.

    Read the fat declaration and ingredients on the exact pack. If reducing fat is your priority, compare plain, uncoated options first.

  • Excluding oily fish just because it contains more fat

    Choosing only white fish can leave out the oily-fish portion included in the NHS recommendation for two weekly fish portions.

    Plan white-fish and oily-fish meals separately, taking account of any dietary advice that applies to you.

  • Overlooking ingredients in a coating

    A coating changes more than texture. Birds Eye’s battered cod ingredients include milk and mustard, while the supplied Young’s battered cod information lists wheat and mustard.

    Check the current ingredients and allergen statement each time, especially if shopping for someone with an allergy or intolerance.

  • Treating ‘boneless’ as a guarantee

    The supplied information for several plain fish packs warns that some bones may remain. Cooking methods also differ between products.

    Take care when serving, and follow the exact pack directions for thawing, cooking and storage.

Questions about frozen fish

Which frozen fish should I check first when reducing fat?

Start with plain, uncoated white-fish fillets or loins and compare fat per 100g on matching preparation bases. Product examples from Sainsbury’s, ASDA and M&S have different declared figures, so the exact pack matters more than a general fish name.

Should I leave oily fish out of a reduced-fat shop?

Not automatically. The NHS recommends two fish portions a week, including one oily-fish portion; plan that meal separately from those for which a lower fat figure is your main consideration.

Can I cook any frozen fish straight from the freezer?

Use the directions for the particular product. Permitted methods and whether thawing is required vary, so follow its pack instructions for storage, preparation and cooking.

Do coated fish products need a separate allergen check?

Yes. Coatings can introduce ingredients beyond fish: Birds Eye’s battered cod lists milk and mustard, while the supplied Young’s battered cod information lists wheat and mustard. Read the current ingredients and allergen statement on the pack you buy.

Can fish labelled boneless still contain bones?

Yes. The supplied information for several plain fish products warns that some bones may remain despite processing, so take care when serving and eating them.
