What are EPA and DHA?

EPA and DHA are a type of fats from omega 3 family. That is, fatty acids that the body produces from omega 3 from diet.

In the liver, our body converts some of these omega-3 fats in some substances called eicosanoids, which are the fats called EPA and DHA. Oily fish is the only food that provides high doses of these components, which are not found in vegetarian diets.

What are EPA and DHA used for?

Among its functions, EPA acts primarily on the cardiovascular system: It is a powerful blood fluidizer, which improves insulin resistance and control of blood pressure, and increases good cholesterol.

DHA fats effects are more focused on the nervous system, where they are in great concentration as part of neurons. They are fats necessary to improve memory and concentration, and also in pregnancy, during the formation of the fetal nervous system. These fats can have benefits on hyperactivity, mild depression, and in some diseases of the nervous system.

In food, only blue fish contains much EPA and DHA.

Problems with the metabolism of EPA and DHA

Although EPA and DHA can be synthesized in our body, some factors may block the transformation of omega 3 EPA and DHA in the liver. (The enzyme delta-6 desaturase is inhibited).

These are: alcohol, tobacco, trans fats, excess saturated fat, and some medications (anti-inflammatory drugs, contraceptives, etc.).

For this reason, some experts believe that EPA and DHA are essential fatty acids, so they should be taken directly from oily fish or supplements, in the case of vegetarian diets.

Foods containing EPA and DHA

Plant foods do not contain EPA or DHA, except for some seaweed, but in very low amounts.

Bluefish is the only significant source of EPA and DHA fatty acids, which do not need any transformation in the liver. Cold-water fish are rich in these components, because they are potent blood thinners, which acts in these animals as natural antifreeze.

Vegetables, vegetable oils, nuts, seeds of cereals and oilseeds contain omega 3 linolenic acid that will be converted in the liver into EPA and DHA.
