It might be an aspergers thing with me about texture, but I don't like the bones. I also can't really eat solid fat on steaks for the same reason.
I think chia seeds have a good source of omega 3, along with good quality grass fed meat, but not close to optimal amounts. These days I supplement with whole foods, desiccated and/or freeze dried and put in pill form. The cronometer app is great for seeing a whole day breakdown and looking for deficiencies, which showed me nearly 0% daily omega 3 without supplementation.
I did hear somewhere that certain populations of people might not get the benefit of omega 3, and that the usually cited studies were done on populations with a long historical trend of eating mainly fish (I'm sorry, I don't have the study to hand, so I can't link it)
