Donut peaches were first grown in China in the 19th century. As a matter of fact, supermarkets love these peaches because they are flat, so you can stack them in a more orderly fashion, not to mention that they are low in acid with a candy-like sweetness and notes of almond. Nutrition-wise, Donut peaches are a good source of vitamin C and fiber, and are also a source of vitamin A and beta-carotene. In addition, they contain potassium, fluoride and iron which in turn eliminates fatigue and many of its sources.
