Nectarines are nearly identical to peaches in both their genetic makeup and nutritional profile. The most obvious differences are their skin and flavor. Peaches are covered with fuzz, while nectarines have thin, smooth skin. Nectarines also have slightly firmer flesh and a more sweet-tart flavor. Although their flavors are distinctive, nectarines and peaches can often be interchanged in recipes.
In addition to being low in calories and rich in fiber, nectarines are a good source of vitamin A, vitamin C, and potassium. These nutrients offer health benefits in terms of improved metabolism, digestion, and heart health.
