Healthy Options for Cashews Vs. Peanuts

Macronutrients

While both of these yummy nuts have about the same amount of calories, peanuts have slightly more protein and fat than cashews, which are a bit higher in carbs. Eating an ounce of dry-roasted cashews adds 163 calories, 4 grams of protein, 9 grams of carbs and 13 grams of fat, including 2.6 grams of saturated fat, to your diet. This is 20 percent of the daily value for fat and 13 percent of the DV for saturated fat. The same amount of dry-roasted peanuts provides 166 calories, 7 grams of protein, 6 grams of carbs and 14 grams of fat, including 2 grams of saturated fat.

Vitamins

Peanuts give you more essential vitamins than cashews. Cashews are a good source of vitamin K, with 12 percent of the DV. Peanuts provide 19 percent of the DV for niacin, as well as 10 percent of the DV for both folate and vitamin E. Your blood wouldn't clot without vitamin K, and you need niacin for turning the food you eat into energy and keeping your skin and nerves healthy. Folate helps create DNA, and vitamin E is an antioxidant that helps keep substances called free radicals from damaging your cells.

Minerals

You'll boost your daily intake of minerals a bit more if you opt for cashews instead of peanuts. Each serving of cashews gives you 19 percent of the DV for magnesium, 14 percent of the DV for phosphorus and 11 percent of the DV for zinc. Eating an ounce of peanuts gives you only 13 percent of the DV for magnesium, 10 percent of the DV for phosphorus and 6 percent of the DV for zinc. You need magnesium for keeping your immune system, muscles and nerves working properly. Phosphorus strengthens your bones and helps form DNA, and zinc is necessary for smelling and tasting, as well as for healing wounds.

Antioxidants

Some of the health benefits of nuts like cashews and peanuts are due to the large amount of antioxidants they contain. Nuts provide about 19 percent of a type of antioxidant called polyphenols in the typical American diet, according to an article published in "Food and Function" in 2012. While cashews and peanuts have similar amounts of total polyphenols, cashews have a much higher percentage of free polyphenols, which increases the effectiveness of these antioxidants.

Use

You need to eat about 1.5 ounces of nuts per day to get the potential heart-health benefits, according to the U.S. Food and Drug Administration. Snack on unsalted cashews or peanuts, sprinkle a few of these nuts into your oatmeal or onto a salad or stir-fry chicken or shrimp along with vegetables and a handful of nuts for a delicious and nutritious main dish. Spread peanut butter or cashew butter onto celery or apples for a quick snack, or have a sandwich of nut butter spread on whole-wheat bread and topped with sliced bananas for a filling lunch.
