Walnuts - you are what you eat

2 min read

Have you ever noticed that a shelled walnut looks remarkably like a brain? It's wrinkly appearance even looks like it has a left and a right hemisphere.

Good for brain function

Walnuts contain a high content of omega-3 fatty acids. Approximately 8% of the human brain’s weight is also comprised of omega-3 fatty acids. Omega-3's are the building blocks for billions of neurons, crucial to the functioning of our brains. The DHA and EPA compounds found in omega-3 play a host of vital roles in neurological structure and function, protecting neurons from oxidative damage, inflammation, and damage inflicted by other influences.

Scientific studies have also found that early deficiencies in the brain content of omega-3's in young children have been associated with poor brain maturation and cognitive dysfunction. It is now recommended that children are given omega-3 supplements if their diets are lacking in omega-3 rich foods.

Other compounds found in walnuts which help protect our brains include: Vitamin E, folic acid, melatonin and antioxidants. There are numerous ongoing clinical trials and research which show walnut consumption may support brain health.

A recent study has found evidence that walnut extract helps to break down the protein-based plaques associated with Alzheimer’s disease, helping to slow its progression.

With all the evidence at hand it's no wonder walnuts have been nicknamed as ‘brain-food’ for a very long time, in the case of walnuts the old adage "you are what you eat" certainly rings very true.

Rich in unique antioxidants

Antioxidants are crucial to your health, as they are believed to help control how fast you age by combating free radicals, which are at the centre of age-related deterioration. Walnuts contain several unique and powerful antioxidants that are available in very few foods.
