The peach (Prunus persica) is a deciduous tree native to the region of Northwest China between the Tarim Basin and the north slopes of the Kunlun Mountains, where it was first domesticated and cultivated. It bears an edible juicy fruit called a peach or a nectarine.
The variety P. persica var. nucipersica (or var. nectarina), commonly called nectarine, has a smooth skin. It is on occasion referred to as a “shaved peach” or “fuzzless peach”, due to its lack of fuzz or short hairs.
A medium peach, weighing 100 g, contains small amounts of essential nutrients, but none is a significant proportion of the Daily Value (DV). Nectarines have similar low content of nutrients. The glycemic load of an average peach (120 grams) is 5, similar to other low-sugar fruits.
