People are so weird about these things. You can tell them and show them how you never get ill, recommend something and they still rely on what mom told them or what they think they know. My friends here are the exact same.
There's a reason folks in Japan live to a ripe old age and are extremely healthy. They eat a lot of fish and rice. Populations who eat a lot of fish tend to be the healthyiest and have longer life spans.
But don't take my word for it

or just Google the benfits of Vitiman D and Omega 3
Vitiman D is the one vit that the majority of us can run short of occassionally or frequently as we now have homes and buildings and aren't exposed to the sun every day. It reduces inflamation which is a major cause of cancer, heart disease etc.
