NEW YORK: A new study has suggested that eating green leafy vegetables can help keep mental abilities sharp.
Something as easy as adding more spinach, kale, collards and mustard greens to your diet could help slow cognitive decline, according to researchers who also examined the nutrients responsible for the effect, linking vitamin K consumption to slower cognitive decline for the first time.
The researchers tracked the diets and cognitive abilities of more than 950 older adults for an average of five years and 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.
