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.[3] 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.
