In a Nutshell: The Health Benefits and Culinary Uses of Nut Meats

With mounting evidence showing their many health benefits, it’s OK to recommend nuts as part of a healthy diet. In fact, it’s more than OK.

Tree nuts are plant-based proteins that contain fiber and a combination of vitamins, minerals and antioxidants for each variety. They are also rich in plant sterols and fat, particularly the heart-healthy mono- and polyunsaturated kinds.

The U.S. Food and Drug Administration has approved a Qualified Health claim that states: Eating 1.5 ounces per day of most nuts as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease. These nuts include almonds, hazelnuts, peanuts, pecans, some pine nuts, pistachios and walnuts — which contain less than 4 grams of saturated fat for a 50-gram (about 1.5 ounce) serving.

The combination of fiber, protein and fat in nuts provides satiety to meals and snacks, making them an excellent option for weight management. There is a caveat, however: portion size. While nuts are healthy, they are calorie-dense. Nuts range from 160 calories to 200 calories per ounce. To get their health benefits without breaking the calorie bank, it’s best to substitute them for other foods in the diet,  particularly those high in saturated fat. This can be achieved with one to two ounces a day.

It’s easy to lump nuts into one category, but what makes each nut meat special is its unique package of nutrients, taste, texture, origin and culinary uses. Here’s a taste … in a nutshell.
