So, you're hungry at work and it's not quite lunchtime. You could reach for the potato chips in the vending machine to hold you over.
Or you could head for a healthier (and arguably tastier) option: walnuts. (Video via YouTube / Chris Nolan)
Walnuts are extremely rich in polyphenols, important chemicals that help your body ward off diseases like cancer, Type 2 diabetes, cardiovascular disease, Alzheimer's disease and more. They're also packed with plenty of protein and fiber.
Dr. Lenore Arab, a professor of medicine and disease prevention at UCLA, says, "It isn't every day that research results in such simple advice — eating a handful of walnuts daily as a snack, or as part of a meal, can help improve your cognitive health."
A tasty snack and a work performance enhancer? Sounds like a win-win.
