The Brain & Omega-3: How Fish Oil Supports Cognitive Function

Cognitive function is the term that refers to mental processes involved in memory, learning and decision making.

There are two levels of complexity, basic and complex. Basic functions are those involved in processing sensory information and remembering basic facts. Complex functions relate to things like reasoning, critical thinking, and creative problem solving.

Key aspects of cognitive function:

• Attention: Ability to focus and filter out distractions.
• Memory: Encoding, storing, and retrieving information.
• Language: Understanding and using spoken and written language.
• Perception: Receiving and interpreting sensory information.
• Executive functions: Planning, problem-solving, decision-making, and self-control.

Factors that influence cognitive function:

• Age: Cognitive function generally declines with age, although individual experiences vary.
• Genetics: Can play a role in cognitive abilities.
• General Health: Diseases, medications, and injuries can affect cognitive function.
• Lifestyle: Exercise, sleep, diet, and stress all impact brain health and cognition.

Fish Oil & Cognitive Function

Fish oil is a common over-the-counter supplement extracted from fatty fish such as salmon, sardines, anchovies, and mackerel. Fish oil is full of Omega-3 fatty acids, which are polyunsaturated fats that give fish oil its cognitive health benefits.

Fish oil contains two types of Omega-3s: EPA (Eicosapentaenoic Acid) & DHA (Docosahexaenoic Acid). EPA & DHA are vital for proper brain function and development in all stages of life, and widely popular for their benefits to heart and skin health.

Memory & Learning:

EPA & DHA are thought to have a role in the brain development of infants. In several studies, a correlation has been identified between pregnant women taking fish oil and higher scores for their children in early childhood tests of intelligence and brain function.

Neuroprotective Effects:

Omega-3 fatty acids may have a neuroprotective properties’ meaning they can help protect nerve cells from oxidative stress and inflammation. By protecting nerve cells, it’s possible that Omega-3’s can contribute to the prevention and delay of certain neurodegenerative diseases.

Brain Structure & Function:

DHA, found in fish oil, is a major structural component of the cell membranes in the brain. DHA plays a crucial role in maintaining the integrity and fluidity of such membranes, which is essential for brain function.

Mood & Mental Health:

Some studies suggest that Omega-3 supplementation might have a positive impact on conditions like depression and anxiety. Mental health conditions can effect cognitive function so helping one can help the other.

Anti-Inflammatory Effects:

Chronic inflammation can be linked to cognitive decline and neurodegenerative diseases. Omega-3 fatty acids have powerful anti-inflammatory properties and including them in your diet may help reduce inflammation in the brain.

Blood Flow to the Brain:

Omega-3 fatty acids can promote vasodilation and reduce blood clot formation, this in turn positively effects blood flow to the brain. Improved blood flow ensures a good supply of oxygen and nutrients, which supports cognitive function.

Omega-3 Fish Oil Supplements

It is recommended by the NHS (UK) that people eat two portions of fish every week. This should be enough to get all the Omega-3 fatty acids we need.

However, this isn’t always possible and for many people Omega-3 Fish Oil supplements present a convenient solution.
