Cashew Nuts

It is a kidney- or heart-shaped achene, in any normal variety. Its color varies from bottle green to grayish brown (dried fruit). It is attached to the end of a fleshy footstalk or peduncle, which is in fact the receptacle of the flower, that is, broadened and swollen, and forms the false fruit.It consists of an edible kernel, surrounded by two shells. The outer shell is smooth and of a bright brown color. Between the two shells, there is a very caustic oily substance. The cashew kernel is considered to be of high nutritive quality, and is covered with a thin reddish brown skin or testa.Cashews are low in sugar and rich in fiber, heart-healthy fats, and plant protein. They're also a good source of copper, magnesium, and manganese — nutrients important for energy production, brain health, immunity, and bone health.
