Eating vegetables helps keep your brain younger! A 2006 study found that eating lots of vegetables was associated with less cognitive decline in older women. This correlation was most potent with a higher intake of leafy greens and cruciferous vegetables — such as broccoli, kale, and cauliflower.
It gets better! Results of a new study from Rush University Medical Center in Chicago reported that eating 1-2 servings a day of leafy green vegetables, such as spinach, kale, and collard greens, can help to preserve memory and thinking skills as a person grows older. After five years, those study participants who ate only 1⅓ cups of lettuce or a little more than just a half a cup of cooked dark leafy greens on a daily basis had a slower decline in thinking skills and memory that comes with age. They were measured to be about 11 years younger mentally on cognitive tests than those who skipped their greens.
It turns out that these vegetables contain a range of nutrients and bioactive compounds like vitamin E and K, lutein, beta-carotene, and folate that help protect the brain. So not only are vegetables essential to keep us slim and disease free but also to keep our mind and memory sharp!
Hopefully, the results of these studies will motivate you to take this month’s Healthy Challenge and eat leafy greens like spinach, kale, lettuce, or collard greens every day. Vegetables, particularly leafy greens, may be your brain’s fountain of youth.
