At first glance, peaches and nectarines are so similar that many people might not even realize there is a difference between the two. Although genetically there isn't a big distinction, a simple genetic mutation separates the two summer stone fruits, giving them differences in appearance, texture, and nutritional value.

Peaches are soft, sweet, and juicy with a light, fuzzy coating that helps prevent the fruit from bruising and damage caused by moisture. Nectarines are also sweet and juicy, but they are smaller than peaches with smooth skin and firm flesh that can actually make them harder to grow.

Nectarines and peaches both contain a number of nutrients like fiber, potassium, niacin, and vitamins A, C, and E as well as immune system-boosting, cancer-fighting antioxidants. However, peaches have more calories, carbs, and sugar, while nectarines have a higher amount of vitamin C and potassium and almost double the amount of vitamin A.
