ômega3

Omega-3 fatty acids are a type of polyunsaturated fat that are essential nutrients for human health. The body cannot produce omega-3s on its own, so they must be obtained through diet. The three main types of omega-3 fatty acids are ALA, EPA, and DHA. ALA is found in plant-based foods like flaxseeds, chia seeds, and walnuts, and the body can convert some ALA into EPA and DHA, though this conversion is often inefficient. EPA and DHA are primarily found in fatty fish such as salmon, mackerel, and sardines, as well as in some fortified foods and supplements.

Omega-3 fatty acids play a crucial role in various bodily functions. They are important components of cell membranes and influence their fluidity. Omega-3s are also involved in reducing inflammation throughout the body, which is linked to a lower risk of chronic diseases. Research suggests potential benefits for cardiovascular health, including helping to lower blood pressure, reduce triglycerides, and slow the development of plaque in arteries. They are also vital for brain health, particularly during development in infants and for cognitive function in adults. Some studies indicate a role in eye health as well. Deficiencies in omega-3s can be associated with dry skin, fatigue, and mood changes. Dietary sources are preferred, but supplements are available for those who do not consume enough fatty fish.
