Does it matter what kind of nuts you eat?

Most nuts appear to be generally healthy. But some may have more heart-healthy nutrients than others. For example, walnuts contain high amounts of omega-3 fatty acids.

Almonds, macadamia nuts, hazelnuts and pecans also appear to be quite heart healthy. So are peanuts — though they are technically not a nut, but a legume, like beans.

It's best to choose unsalted or unsweetened nuts. Adding salt or sugar to nuts may cancel out their heart-healthy benefits.

Here's some nutrition information on common types of nuts. All calorie and fat content measurements are for 1 ounce, or 28.4 grams (g), of unsalted nuts.
