What are omega-3 fatty acids?
Omega-3 fatty acids are a group of polyunsaturated fatty acids that play a key role in the functioning of the body. The most important omega-3 fatty acids include EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid). These substances are essential for the health of the heart, brain, and immune system, but our bodies do not produce them in sufficient quantities, which means that we must obtain them from food or dietary supplements. Omega-3s are found primarily in fatty fish such as salmon, mackerel, and sardines, as well as in flaxseed and nuts.
Benefits of omega-3
Omega-3 fatty acids have a wide range of health-promoting effects. Regular consumption supports heart function and lowers levels of bad cholesterol (LDL) and triglycerides, which reduces the risk of cardiovascular disease. In addition, omega-3s have an anti-inflammatory effect, which is of great importance for people suffering from inflammatory diseases such as rheumatoid arthritis. Omega-3 supplementation is also recommended for the prevention of neurodegenerative diseases such as Alzheimer's disease.
Omega-3 and brain health
DHA fatty acids, a key component of omega-3, are extremely important for proper brain function. They support concentration, memory, and mental health, which is especially important for older people and those exposed to stress. Studies suggest that omega-3 supplementation can improve mood and reduce symptoms of depression.
History and interesting facts about omega-3
Interestingly, the health benefits of eating fatty fish have been known for thousands of years. The traditional Inuit diet, rich in omega-3, was one of the first to alert scientists to the beneficial effects of these fatty acids. Today, omega-3 is widely used as a dietary supplement around the world, and its effects have been confirmed by numerous scientific studies.
Summary
Omega-3 fatty acids are one of the key components for supporting heart, brain, and immune system health. Omega-3 supplements are especially recommended for people who do not regularly consume fatty fish or nuts to ensure they get the optimal amount of these essential fatty acids.
