Calories in Nuts, pistachio nuts

What makes nuts so powerful?

Pistachios are not actually nuts in the botanical sense but rather seeds of the Pistacia vera tree, a member of the cashew family. One of their most distinct biological traits is that the shell naturally splits open while still on the tree, a phenomenon known as dehiscence, which occurs as the seed inside grows and expands until it cracks the hull. The green and purple hues of the pistachio kernel come from the presence of chlorophyll and anthocyanins. Unlike many other nuts that are roasted in oil, pistachios are frequently consumed raw or dry-roasted, which preserves their delicate flavor and prevents the oxidation of their high monounsaturated fat content. The trees themselves are highly resilient, capable of withstanding extreme drought and poor soil conditions, making them a vital agricultural crop in arid regions like the Middle East and California. Furthermore, the pistachio tree is dioecious, meaning male and female flowers grow on separate trees, requiring careful orchard planning to ensure wind pollination.
