Although pistachios are high in fat and calories, the fat they contain is monounsaturated fat. This type of fat can help lower low-density lipoproteins (LDL), or bad cholesterol and reduce the risk of stroke.
The American Heart AssociationTrusted Source says that the majority of the fats in a person’s diet should be monounsaturated fat to reduce the risk of cardiovascular problems. Eating pistachios in moderation should not affect a person’s weight.
One way to moderate pistachio intake is to buy shelled versions. This can help slow down consumption, allowing the person to realize when they are full and reducing the risk of eating too much.
