Know what Omega 3 is

It is a family of polyunsaturated fatty acids, among the top 3 are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which cannot be synthesized by humans and therefore must be synthesized consumed through diet or dietary supplements.

Omega-3 fatty acids are important components of the membranes that surround each cell in the body. DHA concentrations are especially high in the retina (eye), brain and sperm. Omega-3s also provide calories to give the body energy and have many functions in the heart, blood vessels, respiratory system, skin, brain, immune system and endocrine system (the network of glands producing hormones).

Currently, a large number of scientific evidence shows that consuming omega-3 fatty acids helps keep your heart healthy and protects you from many heart problems. In addition, there is plenty of evidence of the role that omega-3 fatty acids play in lipid metabolism, leading to a reduction in triglyceride plasma levels. Thanks to this, they generate a positive effect on atherosclerosis, decreasing the progression of the disease.

Omega-3s are found in some foods such as:

  • Fish and other seafood (especially cold-water fatty fish, such as salmon, tuna, herring, and sardines)
  • Nuts and seeds (such as flaxseed, chia seeds and black nuts)
  • Plant oils (such as flaxseed oil, soybean oil and canola oil)
