Foods that are rich in omega-3 fatty acids

Omega-3 fatty acids are essential for the proper functioning of the human body, particularly the brain, nervous system and retina. The main types of omega-3 include alpha-linolenic acid (ALA), found in vegetable oils such as linseed, rapeseed, walnut and soya, and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found in oily fish such as salmon, mackerel and sardines.

Omega-3 fatty acids offer numerous health benefits: they lower blood pressure, reduce triglyceride levels in the blood and improve the health of the cardiovascular system. They also prevent age-related degenerative diseases such as macular degeneration and reduce the risk of depression and dementia (Anses). Recently, studies have shown that omega-3 fatty acids improve the microbial diversity of the gut microbiota, promoting beneficial bacteria that can prevent diseases such as diabetes and obesity (Doctissimo).

To reap these benefits, it is recommended to regularly consume omega-3-rich foods while diversifying your diet to minimise the risks from harmful substances (Anses).
