What's a healthy serving of nuts?

As much as 80% of a nut is fat. Even though most of this fat is healthy fat, it's still a lot of calories. That's why you should eat nuts in moderation. Ideally, you should use a handful of nuts or a tablespoon or two of a nut spread as a substitute for saturated fats, such as those found in meats, eggs and dairy products.

The American Heart Association recommends eating about four servings of unsalted nuts a week. Choose raw or dry-roasted nuts rather than nuts cooked in oil. One serving is a small handful (1.5 ounces) of whole nuts or 2 tablespoons of nut butter.

Do this as part of a heart-healthy diet. Just eating nuts and not cutting back on saturated fats found in many dairy and meat products won't do your heart any good.
