Fish livers contain beneficial fatty acids

The fishing industry usually discards fish livers, but they are actually a good source of polyunsaturated fatty acids which are beneficial to health, according to a new study.

Fish livers have hardly been used to date, with exceptions such as cod livers, which are used to produce the well-known medicinal oil.

However, these organs contain compounds that are beneficial to health, according to researchers from the University of Almeria, Spain, reports the Journal of Food Composition and Analysis.

‘The livers of edible fish are a good source of long-chain polyunsaturated fatty acids (LCPUFA), especially those in the omega 3 family, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA),’ said Jose Luis Guil-Guerrero, who led the study.

These fatty acids are used to prevent and treat some kinds of cancer, depression, Alzheimer’s disease, schizophrenia, behavioural problems and cardiovascular diseases, according to an Almeria statement.
