THE QUESTION IN FULL
Q. I avoid seafood as I have an allergy to fish. So how would I increase my intake of omega-3 fats? Are fish oil capsules safe for me?
A. Fish oil capsules are quite refined, undergoing several filtration, purification and deodorisation steps to remove impurities, heavy metals and virtually all protein (which is the compound that triggers the allergic reaction).
Because of these processes, theoretically they should be safe but, this may vary from brand to brand.
As you have a documented fish allergy, however, it's wise to be extra cautious. The Allergy Unit of the Royal Prince Alfred Hospital in Sydney (the leading centre for allergies in Australia) suggests you test your reaction by having your doctor do a skin prick test with the contents of a fish oil capsule.

If you have no reaction to the skin prick test, follow it up by swallowing a capsule, but again do it when you're with your doctor.
If you don't want to go through this procedure, there are 3 other ways to boost your intake of omega-3s. These are:
