Omega 3 is an essential fatty acid that is very important for the body to function. As it is not produced naturally by the body, it must be consumed in the form of fats. There are, in general, 3 types of omega 3 : DHA, EPA and ALA. DHA and EPA can be found mainly in cold, deep-water fish that feed on marine animals. ALA, in turn, is found in legumes, nuts and other foods.
Health benefits of omega 3:
First of all, it is good to specify that, for the health of our body, it is important to have a balance between omega 3 and omega 6 fatty acids, which are, rather than vegetables, found, for example, in sunflower seeds, wheat germ, nuts, soy, corn and derived oils. As the doctor explains, “the omega 3 / Omega 6 ratio should be 3: 1, because these levels between the two types of fat have a preventive action in relation to hypertension, type 2 diabetes , immunological and inflammatory disorders and coronary diseases”. Specifically, omega 3 fatty acids have benefits, including:

What is a fatty acid?
Fatty acids are a type of fat present in many types of foods. They can be classified as Saturated, Monounsaturated and Polyunsaturated. Saturated are the fatty acids present in meat and dairy products. Its excessive consumption can lead to circulation problems, such as increased cholesterol in the blood. Monounsaturated fatty acids, on the other hand, are found mainly in vegetables and can bring some benefits, such as reducing the risks of high blood pressure.
Polyunsaturated fatty acids, on the other hand, are called essential, as they cannot be produced directly by the body, and must be obtained from external sources, that is, from food.
Essential fatty acids:
Essential fatty acids are very important for the body as they can be used as energy by the cells of our body. In addition, they act as clotting agents and, as they have antioxidant action, help maintain skin elasticity and fight premature aging.
Types of Omega 3 :
In general, there are 3 types of omega 3 : alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
EPA and DHA are found more commonly in fish and seafood, and studies indicate that they have more health benefits than ALA, which is more commonly found in plant-based foods such as flaxseeds, walnuts. and soybean oil. Understand the difference:
- EPA: EPA has anti-inflammatory action, as it helps the enzymatic reactions responsible for the production of essential substances to combat inflammation that neutralize the pro-inflammatory activity.
- One of the main benefits of this type of omega 3 is in helping the health of the heart and blood circulation, as it helps to prevent the formation of thrombi (clots) in the blood,
- thus decreasing the risk of thrombosis and stroke.
- People who suffer from cellulite, obesity, lupus and rheumatoid arthritis, for example, can benefit greatly from consuming EPA.
- DHA: In addition to having antioxidant action, DHA is essential for the development of the fetus. It helps in the formation of the retina (part of the eyes responsible for transforming the stimulus
- light in nerve stimulation).
- It is the most beneficial type of fatty acid for brain health, as it favors cognition and connections between neurons, benefiting memory, attention, reasoning, imagination,
- judgment and several other aspects related to the human mind.
- ALA: Plant-based, ALA can be converted to DHA or EPA after ingesting. The human body is capable of producing enzymes that make this transformation, however, their activity is reduced by factors such as smoking, alcohol consumption, diabetes, stress, high intake of trans fats and, mainly, by aging.
