How much oily fish should I eat?

The current official guidance is for at least two portions of fish per week (140g), at least one of them oily.

The official maximum limit is up to four portions of oily fish per week for most people, but only two for women who are pregnant or planning to be, or who are breastfeeding. The reason for this is that some pollutants can contaminate fish.

Research suggests that the long-tem benefits of eating oily fish, or the equivalent in supplements, for children’s mental development, motor and social skills – as well as supporting the mother’s mental health and wellbeing – may well outweigh the theoretical risk of any possible contamination.
