People have long known that nuts are part of a healthy diet. However, scientists in the Netherlands recently found that you do not need to eat many to get all the health benefits.
    The researchers found that eating a handful of nuts or peanuts every day is linked to a lower risk of death from several major diseases. They say that eating nuts protects the health of both men and women. Professor Van Den Brandt adds that you do not need as many nuts as health experts earlier suggested. About 10 grams a day is enough to get the full health benefits of nuts. That is about an average-sized handful. Nuts are high in fat and calories. So, eating a handful before dinner can help you to eat less. But eating too many can ruin your appetite altogether.
    However, the researchers found that many peanut butters did not give the same health benefits as plain peanuts. That is because most peanut butters contain added oils and sugars.
