Ratna1, sorry for late reply to your post. I’m playing catch up. I want to congratulate you on your efforts. Very well stated and you make some impressive points.
Ratna before you get locked into the idea that there is absolutely no benefit from taking DHA/EPA " fish oils "..be aware of the following from the VITAL trial that indicated there may be some benefit for those who eat very little fish .
In subgroup analyses, baseline dietary fish intake modified the n-3 intervention effect on major cardiovascular events (Fig. 2) and total myocardial infarction (Supplementary Appendix Fig. S3), with nominally significant reductions of 19% and 40%, respectively, in participants with below-median intake (<1.5 servings per week) but no reductions in those with higher intake (nominal p-interaction<0.05 for both). The HR for myocardial infarction among those who ate fish less than once per month was 0.43 (0.21-0.91).
