Vitamin K intake slows cognitive decline

LeafyGreensIn recent years B-vitamins, essential fatty acids, folate and vitamin D have been linked to preventing cognitive decline.

Now, for the first time, vitamin K has also been linked to preventing the dreaded condition.

According to research¬† published in Science Daily, something as easy as “adding more spinach, kale, collards and mustard greens to your diet” could help slow cognitive decline.

According to Science Daily, the research, conducted at Rush University Medical Center, was responsible for “linking vitamin K consumption to slower cognitive decline for the first time.”

For the Rush University study researchers tracked the diets and cognitive abilities of more than 950 older adults for an average of five years.

In compiling the data the researchers saw a significant decrease in the rate of cognitive decline for study participants who consumed greater amounts of green leafy vegetables.

People who ate one to two servings per day had the cognitive ability of a person 11 years younger than those who consumed none.

When the researchers examined individual nutrients linked with slowing cognitive decline, they found that vitamin K, lutein, folate and beta-carotene were most likely helping to keep the brain healthy.

“Our study identified some very novel associations,” said Martha Clare Morris, Sc.D., assistant provost for community research at Rush University Medical Center and leader of the research team.

“No other studies have looked at vitamin K in relation to change in cognitive abilities over time, and only a limited number of studies have found some association with lutein.” Other studies have linked folate and beta-carotene intake with slower cognitive decline.

The researchers presented the research at the American Society for Nutrition Annual Meeting during the Experimental Biology 2015 convention in Boston earlier this year.
