Omega 3 and Brain Health

omega 3 and brain health

We know that brain volume is not connected to intelligence, but it has become common knowledge that Omega 3 and brain health are linked. As we age, our cognitive abilities take the toll of our lifestyle, hereditary baggage and diseases. Recent studies suggest that Omega 3 fatty acids are more beneficial for us than we ever thought. You can get them from eating tuna and salmon as well as other seafood and nuts. Omega 3 fatty acids play an essential role in the brain’s developments and proper function.

The best way to recognize the benefits of something is when it’s missing. Omega 3 fatty acids are no exception. While scientists may have a hard time deciphering how Omega 3 helps our brains, it’s easier for them to identify how the brain reacts when it lacks the beneficial substances. People who don’t get enough fatty acids into their body by eating fish or taking supplements have greater risks to develop dementia, schizophrenia, depression and ADD.

What do Omega 3 fatty acids do for the brain?

We’re still in the dark about how fatty acids improve cognitive functions and help our brains stay healthy for longer. However, researchers might have pinpointed how the fatty acids improve brain health. The brain’s synapses are small openings that allow neurons to pass their impulses from one to another. For the impulses to cross over to other neurons, they have to pierce the membrane which surrounds them. Since this membrane is composed almost exclusively of fats, researchers have come to believe that Omega 3 intake from fish and supplements will help maintain the membrane’s elasticity, allowing the impulses to travel smoothly.

Omega 3 fatty acids brain benefits

Researchers believe that omega 3 and brain health are closely linked and that we need the fatty acids from the moment we are born as we grow up and get old. These are a few of the boosting benefits of the Omega 3 fatty acids on the brain:

  • Memory enhancer – Omega 3 is the best ally for learning. A study conducted on children with ages between 7-12 years showed that supplements helped them focus and score better on memory tests.
  • Combat depression and mood disorders – studies have shown that Omega 3 fatty acids can prevent people from developing depression and helps depressed patients improve their mood.
  • Fight against cognitive deterioration – recent evidence points to Omega 3 fatty acids’ ability to fight off dementia symptoms and age related brain weakening.

Other uses for Omega 3

  • High cholesterol and high blood pressure – evidence suggests that Omega 3 fatty acids from fish can balance triglyceride levels and can decrease blood pressure;
  • Diabetes – patients with diabetes can lower triglycerides by incorporating fish and flaxseed into their diet;
  • Osteoporosis – omega 3 fatty acids could help promote bone health and strength;
  • Rheumatoid arthritis – fish oil can fight off rheumatoid arthritis symptoms, reducing stiffness and pain.


Omega 3 and brain health is still an ongoing research field, but the benefits of fatty acids are unquestionable. They help fight off old-age related problems, promoting brain function and cognitive abilities, which are the main reasons why we should incorporate tuna, salmon and seafood in our diet.
