5 impressive benefits of omega-3

Omega-3 fatty acids are obtained through the diet and are vital for a healthy brain and body. They form the structure of every cell wall, provide energy, and are involved in the function of the heart, lungs, blood vessels and immune system. The three most important omega-3s are ALA (alpha-linolenic acid), DHA (docosahexaenoic acid), and EPA (eicosapentaenoic acid). ALA is mainly found in plant sources such as nuts and seeds, while DHA and EPA are primarily found in fish and algae. DHA is perhaps the most important omega-3 fatty acid, as it is a crucial component in the brain, retinas and sperm cells, and is found in extremely high levels here.

Omega-3 supplements, such as fish oil, are often recommended for people who don’t eat many foods that contain these important fatty acids. Find out about the numerous health benefits of omega-3 below.

Eye health

DHA is a major structural component of the retina in the eye, which sends visual information to the brain, enabling you to see. A lack of DHA has been linked to vision problems and macular degeneration - one the leading causes of blindness worldwide. Research suggests that omega-3 fatty acids may help reduce the risk of macular degeneration and vision impairment.

Brain function

Omega-3s are essential for brain growth and development in children. High omega-3 intake during pregnancy is associated with higher intelligence, better social skills, and fewer behavioural disorders, such as ADHD. Scientists believe omega-3 acid supplements may also help fight anxiety and depression - one study found that EPA may be as effective at treating depression as antidepressants. 

Reduce risk of heart disease

High cholesterol and blood pressure, and chronic inflammation, are all risk factors for heart disease - one of the leading causes of death worldwide. Omega-3s help lower risk of heart disease, heart attacks and stroke by:

  • Reducing levels of fats in the blood called triglycerides. These can build up in the arteries and cause artery walls to harden or thicken.
  • Reducing blood pressure.
  • Increasing levels of HDL “good” cholesterol, which helps remove other forms of harmful cholesterol.
  • Preventing blood platelets from sticking together and forming blood clots.
  • Reducing inflammation by limiting the production of inflammatory substances.

Reduce inflammation

Chronic or persistent inflammation underpins almost every type of disease or illness, such as cancer and obesity. Research has linked high omega-3 intake to reduced inflammation, as these important fatty acids help reduce the production of inflammatory molecules, such as eicosanoids and cytokines. 

Lower risk of autoimmune diseases

Autoimmune diseases arise when the immune system malfunctions and mistakes healthy cells in the body for foreign cells, and starts attacking them. For example, in type 1 diabetes, the immune system starts attacking insulin-producing cells in the pancreas, which hinders the body’s ability to manage blood sugar levels. Omega-3s may help reduce the risk of multiple autoimmune diseases, especially if consumed in high quantities early in life.

These are just a few of the health benefits of omega-3 fatty acids; they may also help reduce risk of metabolic syndrome, asthma, mental disorders, cancer, liver disease, and bone conditions.
