We tend to think that a loss of mental acuity is just part of getting older — but age is not the only contributing factor to cognitive decline. Our lifestyle also plays a key role. Poor diet, a lack of sleep and exercise, ongoing stress, smoking and environmental pollutants all damage fragile brain cells.
Fortunately, mental deterioration is not irreversible. In fact, the brain is incredibly dynamic and has the potential and the ability to change at any point throughout our entire life. And, you have the power to enhance your brain function, protect your brain from damage and counteract the effects of aging! It all comes down to your everyday decisions.
Here are 5 small changes you can make in your life that can mean big differences in your cognitive abilities:
Omega-3 fatty acids — which are found in brain fuel foods like salmon, flaxseed and walnuts — offer a number of health benefits, such as improving cognitive performance and warding off mental and mood disorders. They support brain plasticity, which is your brain’s ability to change in response to stimulation demands placed on it, which could then enhance the expression of several molecules related to learning and memory.
In one of the largest studies of its kind, researchers analyzing the diets of 12,000 pregnant women found that children of those who consumed the least omega-3’s were 48% more apt to score in the lowest quartile on IQ tests. And in a similar study, 396 children between the ages 6 and 12 who were given a beverage with omega-3 fatty acids showed higher scores on tests measuring verbal intelligence and learning and memory after 18 months than a control group of students who did not consume the drink.
A deficiency of omega-3 fatty acids in humans has also been linked to a increased risk of mental disorders such as attention-deficit disorder, dyslexia, dementia, depression, bipolar disorder and schizophrenia. One study found that individuals who consumed more omega-3s had increased volume of the brain’s gray matter volume, especially in the hippocampus, the part of the brain associated with self-awareness, compassion and introspection.
For all of these reasons, if you’re wondering how to sharpen your mind, give it the right brain fuel by consuming more healthy fats.
DRINK SOME GREEN TEA
A rich source of antioxidants, nutrients and minerals, green tea is well known for its ability to protect the body from free radicals and for its power to increase fat burning and boost the body’s metabolic rate. But did you know that it has the potential to enhance cognitive function, and, in particular, boost the working memory and stimulate your brain?
