Omega-6 Fatty Acids: The Other Essential Brain Fat
We’ve all heard about the brilliant benefits of getting enough omega-3 fatty acids in our diet, but omega-6 fatty acids don’t get as much coverage, and have even suffered negative press in the past. Why is that? Well, today we’re going to uncover the facts and balance the narrative on essential fats, shedding light on the true effects of omega-6s on our brain health.
What are omega-6 fatty acids?
A type of group of PUFAs (polyunsaturated fatty acids), they belong to the EFA (essential fatty acids) family. Just like omega-3s, they are not naturally manufactured by the body and must be acquired through food. The main omega-6 fatty acid in our diet is LA, or linoleic acid, found in seeds, nuts, vegetable oils, and certain meats. LA can then be converted into GLA (gamma-linolenic acid) and AA (arachidonic acid).
What function do they perform in the brain?
Omega-6s, and AA in particular, form an integral component of cell membranes. These membranes promote fluid communication between neurons, controlling the passage of nutrients and ions and aiding synaptic plasticity.
They’re also crucial for brain development, helping to mature healthy brain cells in fetal and childhood stages that influence behavior and cognitive function throughout life.
More positive effects of omega-6 fatty acids
Studies on infants and children have revealed that, in combination with omega- 3s, proper levels of omega-6s are necessary for normal cognitive development.
Omega-6s are also a crucial part of inflammatory processes, immune responses, and blood flow regulation. A healthy inflammatory response helps to eliminate pathogens, protect neurons, and repair damaged tissue.
The key? Finding the right balance
Now we know the main roles of omega-6s, let’s touch on the controversy. Essentially, an excess of them can lead to detrimental effects in many of the aforementioned areas. It can also cause an overactive neuroinflammatory response that is associated with cognitive decline and various neurogenerative diseases.
However, they are essential to our diet, and in combination with omega-3s, help regulate inflammation, assist in optimal neurodevelopment and mental health, and contribute to the intricate structure of neuronal cell membranes.
So, as with many things in life, it’s all about balance. Both omega-3 and omega-6 fatty acids are beneficial for the brain in the right quantities. Our advice? Make sure you’re getting enough of both to strike the right ratio for optimal brain health in the long term.
