Omega-3s and Cooking

Q: Does cooking decrease the amount of healthy Omega 3s in foods?

A: I’m glad to hear that you are working to increase the amounts of omega-3 fatty acids in your diet. There is substantial evidence of their benefit to cardiovascular health.

Among the richest sources of omega 3 are flaxseeds, walnuts, salmon, halibut, shrimp, snapper, scallops, tofu/soybeans and winter squash.

Cooking does not decrease the amount of omega-3.

Enjoy your healthy diet!

Sardines, kippers (herring) and trout are also 'oily' fish and contains high quantities of omega-3 fatty acids. Make sure your fish are from sustainable sources though.

If you are from the UK or north-west Europe you can check your fish sources from the 'Pocket Good Fish Guide' from the Marine Conservation Society here:

If you are from the US you can also download a good fish guide, that is appropriate for your US region, from here:
