Walnuts are said to be rich in fiber, vitamin B, magnesium, and antioxidants such as Vitamin E. They are also loaded with more omega 3 fatty acids than any other types of nuts. Omega 3 fatty acid has been shown to lower cholesterol. In addition, walnuts assist in reducing the risk of heart disease by improving elasticity of blood vessels and reducing plaque accumulation.
Furthermore, the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University in Boston, Massachusetts has conducted a study observing
the effects of walnut consumption on behavioural and motor skills.
Our brain ages with us and as such, changes occur that alter or impair neurons in our brain. The synaptic connections in the brain can become weak or change entirely altering the functions of relative connections. Increased oxidative damage to neural tissue also alters the way in which our brain functions. In the study, aged rodents displayed these types of changes behaviorally through impairments in performance on age-related tasks such as balance, coordination, and spatial working memory.
The study consisted of 4 distinct groups of aged rats of similar weight. The diet of the first group of rats consisted of a chow mix containing 2% walnuts, the second 6%, third 9% and fourth 0%. The rats were then subjected to a battery of memory and motor tests. In comparison, the group that ingested 6% walnut in their chow mix would be equivalent to a human eating 1 ounce or 7 to 9 walnuts per day.
“The study found that in aged rats, the diets containing 2 percent or 6 percent walnuts were able to improve age-related motor and cognitive shortfalls, while the 9 percent walnut diet impaired reference memory.”
It seems that a healthy diet and 7 to 9 walnuts per day could be beneficial in reducing the effects of aging on motor and behaviour skills.
