Latest Studies on Brain-Health Nutraceuticals

As the U.S. population ages, brain health is top of mind for consumers looking for solutions to maintain their cognitive edge. A 2015 report by the Alzheimer’s Association found that 1 in 9 Americans aged 65 or older has Alzheimer’s disease, while 14% of Americans over the age of 71 have some form of dementia.(1) Put another way, every 67 seconds, someone in the United States develops Alzheimer’s disease. The annual number of new cases of dementia (including Alzheimer’s) is expected to double by 2050.
While these numbers are staggering, research is showing that dietary factors can play a role in stabilizing long-term cognitive health. Traditional diets, such as those based on Mediterranean or Ayurvedic principles, have been found to be protective of brain health. A recent study found that Mediterranean dietary practices in individuals with age-related cognitive decline are associated with improved cognitive function.(2) Research also demonstrates the neuroprotective role of herb and spice intake.(3) Studies into specific components of healthy diets have shown them to have substantial benefits for memory and cognitive health. Some of the most promising elements include healthy fats from fish and olives, polyphenols from fruits and other sources, and curry spices such as turmeric.
