When I was a kid, my mom used to say that fish was brain food. I now realize that she was right! Your brain is made up of DHA. That’s docosahexaenoic acid, an omega-3 fat, that is important for the brain, nervous system, and eyes.
Fish is the best source of DHA.
Fish can also help prevent heart disease because it’s a source of EPA, eicosapentaenoic acid. Another omega-3 fat!
If you’re planning for pregnancy, pregnant, or breastfeeding, it is recommended to limit fish high in mercury, as this substance can harm the brain of a developing fetus and a young child.
So the trick is to eat fish that is high in DHA and EPA, but low in mercury. Learn about which types of fish to eat on our previous post “Brain food for you and your baby“.
A popular and affordable fish that is low in mercury and can be a good source of DHA is canned light tuna.
This recipe uses canned light tuna which is high in protein, phosphorus, potassium, selenium, and is a source of magnesium, vitamin D, and vitamin B12.
Kids will love these tuna melts since they are tasty, simple, and a quick recipe to make. It will also get them cooking with you in the kitchen! As a bonus this recipe is rich in vitamin A, calcium, folacin and loaded with flavour.
Feel free to use different types of cheese, and try it with canned salmon, which is also low in mercury, for even more DHA for the brain!
