A new study has revealed that a diet can effectively boost brain health and significantly reduce the risk of cognitive decline.
According to the American “CNN” network, this system depends on eating fruits, vegetables, whole grains, beans, seeds, nuts, plenty of virgin olive oil, fish full of omega-3 fatty acids, and reducing red meat, cheese, fried foods, pastries and sweets.
Among the most important vegetables that the researchers emphasized the need to eat in this system daily are dark leafy vegetables, such as watercress, cabbage, kale, lettuce, and spinach, while they pointed out that the most important fruits that must be eaten 5 times a week are berries, grapes, and strawberries.
In addition, three servings of whole grains should be eaten daily, poultry twice a week, while fish should be eaten at least once a week.
The researchers also pointed out that this system is concerned with reducing salt as much as possible, in order to reduce blood pressure and cholesterol, which can lead to strokes and constriction of small blood vessels, and may cause dementia.
The study, published Tuesday in the New England Journal of Medicine, followed 604 people over the age of 65 who all had symptoms of early-stage Alzheimer’s disease.
Half of those participants were asked to follow this diet for three years, while the other half were asked to continue eating their usual diet for the same length of time.
The team conducted a series of cognitive tests for all participants at the beginning and at the end of the study.
The team found that the group that followed this new diet had a clear improvement in cognitive function. Magnetic resonance imaging (MRI) showed that the regimen decreased white matter density (which is associated with Alzheimer’s) and increased the volume of both gray matter (the brain’s cognitive center) and white matter (which helps transmit signals between neurons in the brain).
Despite these impressive results, the study’s lead author, Dr. Lisa Barnes, associate director of the Alzheimer’s Disease Research Center at Rush University Medical Center in Chicago, emphasized that eating any healthy diet, regardless of type, may improve brain cognitive function, but to varying degrees.
