If you're expecting, there's no need to miss out on shellfish. According to the UK Food Standards Agency, shellfish is safe to eat while pregnant as long as it's well cooked.

In fact, it's an important and healthy protein, high in Omega-3 fatty acids, which, together with other nutrients, are vital for the development of your baby's brain, eyes and nervous system.

Shellfish is also low in saturated fat, so why not try healthy recipes like crab cakes or a quick prawn stir-fry? Just remember that raw shellfish carries a risk of food poisoning so be sure it is thoroughly cooked.
