A large proportion of the most common food fish – such as herring, sardines and anchovies – are currently processed into fishmeal and fish oil. However, they could also be eaten directly, as they are rich in omega-3 fatty acids, vitamin B12 and calcium. As an alternative to red meat, this could save 500,000 to 750,000 lives worldwide every year, according to a study published on Tuesday in the journal BMJ Global Health.
