The recommended levels of fish oil
To maintain the CV health in normal adults, most recommenda- tions fall in the range 0.25 to 0.5 g per day of EPA plus DHA. EPA plus DHA in fish oils from the different species ranges from 11% in herring oil to 26% in and anchovy oil. So taking the lower end of the recommendations, this would be met by 2.5 g/day herring oil or 1 g/day anchovy oil. By concentrating fish oils, e. g. by win- terisation, the amounts needed can be considerably reduced. Alternatively, one portion of cooked oily fish such as sardine, pil- chard, mackerel, salmon or trout provides over 15 g fish oil. Sev- eral authorities, such as the UK's food standards agency, recom- mend eating fish twice a week, one portion of which should be oily.
