in the final said people should take more cis fat, to laymen that's not clear enough. how about adding "vegetable oil and fish oil"?

and how to choose the msot suitable ones? as fang already said among plant oils there are still quite some difference on cis/trans ratios, which plant oil is the best choice? and for fish oil, there's also concern about heavy metal contamination.
