Just because you are on a diet, doesn't mean you ditch nuts completely. They may be high in fat, but it's the good, monounsaturated fat.

In a study at Brigham and Women's Hospital in Boston, researcher Kathy McManus found that nuts could reduce your risk of heart disease and even help you lose weight!

And get this... the magnesium in nuts reduces symptoms of PMS such as bloating, mood swings, and headaches. So ladies, pop those nuts when you think you are losing your cool.
