Individuals who eat plenty of fresh produce, whole grains and lean meat often experience significant physical health benefits when compared to people who favor diets high in fat and carbohydrates.
Now, researchers at the Veterans Affairs Puget Sound Health Caalzre System have suggested that a diet that is good for the heart and waistline may also have positive benefits for the mind.
In a four-week trial, the scientists found that a diet that was low in saturated fats and simple carbohydrates resulted in reduced levels of biomarkers for Alzheimer’s disease as well as lowered cholesterol. Additionally, a healthy diet was shown to improve memory test scores for both normal participants and those experiencing mild cognitive impairment.
“The therapeutic effects of longer-term dietary intervention may be a promising avenue of exploration,” said study authors. “In addition, identification of the pathophysiologic changes underlying dietary effects may reveal important therapeutic targets that can be modulated through targeted dietary or pharmacologic intervention.”
Results of this study were published in a recent issue of the journal Archives of Neurology.
