A nut is a fruit composed of an inedible hard shell and a seed, which is generally edible.
Most seeds come from fruits that naturally free themselves from the shell, unlike nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary.
The general and original usage of the term is less restrictive, and many nuts (in the culinary sense), such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense.
The translation of “nut” in certain languages frequently requires paraphrases, as the word is ambiguous.
From prehistoric man to ancient royalty to medieval peasants to supermarket shoppers of today, nuts have been a reliable food source throughout history.

Walnuts have always been considered as “Brain Food”, perhaps because the surface structure of the walnut has a crinkly appearance like that of the brain. Due to this reason, they have been considered as a symbol of intelligence, leading to the belief that they actually increase one’s intellect. While this is not exactly true, recent studies have proven that the consumption of these seeds does help in promoting brain function.
The pollination of California’s almonds is the largest annual managed pollination event in the world, with close to one million hives (nearly half of all beehives in the US) being trucked in February to the almond groves. Much of the pollination is managed by pollination brokers, who contract with migratory beekeepers from at least 49 states for the event.

The Pistachio Principle is a simple, mindful eating concept that can help fool yourself full, without feelings of deprivation. The premise of The Pistachio Principle is that consumption of in-shell pistachios may help to slow eating because the leftover shells offer a visual cue about the amount of pistachios you’ve consumed. And that can potentially reduce your calorie intake.
