It‘s not often that a simple, doable thing comes along that’s also incredibly good for you, but I think this is it: eat a half a handful of nuts every day.According to a new study out of the Netherlands, just 10 grams (about a third of an ounce) of nuts or peanuts (technically a legume) a day leads to a lower risk of death from respiratory and cardiovascular diseases, neurodegenerative disease, diabetes and cancer. There was no benefit to eating peanut butter.
