Vitamin K may help in the prevention of cognitive impairment.
Just one serving of green leafy vegetables a day may protect memory and reduce the risk of dementia, reveals new study of American Scientists.
The study, which lasted five years, was attended by more than 950 adults. They were asked to complete a questionnaire that included questions about their overall lifestyle habits, including eating habits. The researchers then analyzed the memory of participants using different tests.
The results showed that participants who consumed every day at least one serving of dark green leafy vegetables such as spinach or kale, have better memory and a lower risk of developing dementia, compared to participants who dark green leafy vegetables eaten rarely or not at all.
Scientists believe that this is so because a high level of vitamin K, for which previous studies have already shown that it can help in the prevention of cognitive impairment.
