Fatty but healthy foods

Omega-3 fatty acids are ALA, EPA, and DHA, which are essential for humans. ALA is found in vegetable oils, while DHA and EPA are found in fish, shellfish, and algae. The body can convert ALA to EPA and DHA, but the conversion rate is less than 15%.

Effects of omega-3

Omega-3 fatty acids are essential for both physical and mental health.

Physical health benefits

Omega-3 is an essential component of cells, helping cells function effectively. This fatty acid also supports the formation of eicosanoids which play an important role in the cardiovascular, pulmonary, immune and endocrine systems.

Mental health benefits

According to a 2020 review, omega-3s are good for brain development and function. Polyunsaturated fats—including omega-3s and omega-6s—make up 20% of the brain’s weight. Omega-3 deficiency has been linked to an increased risk of developing a range of mental disorders, including depression, bipolar disorder, and attention deficit hyperactivity disorder.
