Peach Nutrition Facts

Peaches are a source of carbohydrates, specifically fibrous carbohydrates, as well as a good source of micronutrients. Peaches are best consumed with the skin on for maximum nutritional value, as the skin contains most of the fiber, and are a good source of vitamin C, vitamin A, and potassium. One medium peach (147 grams) contains 68 calories, 1 gram of protein, less than 1 gram of fat, 15 grams of carbohydrate, 12 grams of sugar, and 2 grams of fiber (1).

Moreover, the high-water content of peaches, roughly 88% water, makes them a very hydrating fruit and, therefore, a great addition to any summer breakfast.
