What is Seafood Intolerance?
If you have an intolerance (defined by YorkTest as a food-specific IgG reaction) to seafood or shellfish, your body produces an inflammatory response to the fish or shellfish proteins present.
Unlike seafood allergy, the effects of seafood intolerance are usually delayed, and are not life threatening but can cause you to feel unwell.
Where to look
If shellfish is present in a food product, it is usually listed on the packaging. However, it is a good idea to familiarise yourself with the various types of seafood and shellfish to be aware of if you have a seafood intolerance.
- White fish (cod, plaice, sole, coley, haddock, pollock, monkfish)
- Oily fish (mackerel, tuna, sardines, anchovies, salmon, pilchards, herring, trout, tuna)
- Molluscs (clams, mussels, oysters, snails, scallops, squid, octopus)
- Crustaceans (crab, lobster and shrimp)
Replacements for a balanced diet
White fish is an excellent source of protein, vitamins and minerals. The Food Standards Agency recommends that we eat at least two portions of fish a week, with at least one of these being oily fish which is particularly nutritious.
However, if you are suffering from a seafood intolerance, it is important to discover which seafood in particular you react to and to make sure you include suitable fatty acid replacements in your diet such as:
- Leafy greens such as spinach
- Walnuts, brazil nuts, hazelnuts and pecans
- Olive oil and flaxseed oil
- Sesame butter, pumpkin seed butter
- Coconut oil
