Opportunities to enhance alternative sources of long-chainn-3 fatty acids within the diet
Health benefits or advocated health benefits of long-chain (LC) n -3 PUFA are better known by medical doctors as well as by consumers, so that consumption increases.

Health benefits or advocated health benefits of long-chain (LC) n -3 PUFA are better known by medical doctors as well as by consumers, so that consumption increases. In addition, the development of aquaculture requires more fishmeal and fish oil. Humanisation of care of companion animals is also associated with addition of LC n -3 PUFA in pet foods. The risk of the increased demand for LC n -3 PUFA is the excess harvesting of natural sources, especially of marine origin (oily fishes, krill). In order to improve sustainability, alternative sources of LC n -3 PUFA have been developed. These alternative sources are: (a) terrestrial plants naturally or genetically enriched in stearidonic acid (SDA), which bypasses the first limiting step of (i.e. ∆6 desaturase) of the biosynthesis of LC n -3 PUFA; (b) single-cell oils rich in LC n -3 PUFA (microalgae, Escherichia coli ) and krill.
