Taking care of your heart and brain health is very important, as they have a direct impact on your quality of life. Among the nutrients that have proven effective in this area is omega-3, an essential nutrient.
Omega-3 is known for its ability to support heart function and improve mental and mood performance. This fatty acid is found in many natural foods, especially fatty fish, and can also be obtained as a dietary supplement.
What is omega-3?
Omega-3 is an essential fatty acid that the body cannot produce and must be obtained from food or supplements. It is available in three main forms: ALA from plants, and EPA and DHA from marine sources.
Omega-3 is found in fish oil, walnuts, flaxseeds, and fatty fish such as salmon and sardines, and plays a vital role in supporting overall health, especially the heart and brain.
How does omega-3 support heart health?
Omega-3 helps reduce risk factors associated with heart disease by:
- Lowering blood triglyceride levels.
- It helps reduce high blood pressure and improve the elasticity of blood vessels.
- It reduces the risk of blood clots.
- It reduces inflammation that can cause damage to blood vessels and arteries.
The Effect of Omega-3 on the Brain and Cognitive Function
Omega-3 is an essential component of brain cells and plays a role in improving mental function, as:
- DHA makes up a large portion of brain cells and supports memory and concentration functions.
- Its deficiency can lead to a decline in cognitive abilities with age.
- It improves neural communication and protects against cognitive decline.
Omega-3, Children's Health, and Mental Development
Omega-3 contributes to the healthy development of the brain and vision in fetuses and children, as:
- DHA is important for the development of the fetal nervous system.
- It is recommended during pregnancy and breastfeeding to support children's intelligence and neurological development.
- It improves mental and behavioral skills in children.
The Role of Omega-3 in Preventing Depression and Anxiety
Omega-3 intake is associated with reduced symptoms of anxiety and depression:
- EPA has positive effects on psychological well-being and mood.
- It is used as a supportive supplement in some depression treatment protocols
- It helps balance neurotransmitters in the brain, such as serotonin.
Recommended Daily Dose
Moderate intake of omega-3 ensures optimal benefits without adverse effects:
- Health authorities recommend consuming 250 to 500 mg of EPA and DHA daily.
- The dosage may vary depending on health conditions and age.
- It is best to consult a physician before starting supplements, especially if you have chronic conditions.
Natural Sources of Omega-3
Omega-3 is found in a wide range of healthy foods and supplements:
- Fatty fish such as salmon, mackerel, and tuna.
- Fish oil and krill oil are available as dietary supplements.
- Flaxseeds, chia seeds, and walnuts are plant-based sources of ALA.
- It is recommended to eat two servings of fish per week to achieve the appropriate amount.
Warnings and Potential Drug Interactions
Despite the benefits of omega-3, there are some caveats to be aware of, including:
- High doses may increase the risk of bleeding.
- May interact with blood-thinning medications such as aspirin and warfarin.
- Should be used with caution in patients with liver disease or blood clotting disorders.
Caution: Consult a physician before regular supplementation.
Foods Rich in Omega-3
Omega-3 is found in a wide range of natural foods, including:
Fish such as salmon, sardines, mackerel, tuna, and herring; cod liver oil; and eggs fortified with omega-3.
Plant sources such as flaxseeds, chia seeds, walnuts, flaxseed oil, canola oil, soybeans, spinach, and algae.
