I think they change the ratio of LDL / HDL , i.e. they increase the HDL level which is good since, there is less cholesterol in periphery arteries to clog them.

I think they change the ratio of LDL / HDL , i.e. they increase the HDL level which is good since, there is less cholesterol in periphery arteries to clog them. i also remember them having an effect on triglycerides (overall decrease), so i still don't think that omega 3 effects on cvd is BS since those are some of the key factors of the genesis of arteriosclerosis, so it might not help the Heart itself directly , but i am pretty sure there are huge vascular advantages and that's mostly anyway what's messing up the heart in the ende.
