Almonds come from the almond tree. They are a type of stone fruit that is in the same family as the peach, plum and cherry.
No one is quite sure when almonds were discovered, but they were mentioned in the Bible. After that, they were used to make bread served to Egyptian pharaohs. Almonds made their way to America in the 1700's when they were brought over by Franciscan priests.
People of that time loved almonds, but had a hard time growing them. The weather was too cool and moist to facilitate growth. Finally, during the late 1800's, farmers found a way to grow them in America.
As of 2014, California is the only state in North America that grows almonds for commercial purposes, with almonds being the state's largest tree nut crop. Almonds are said to prevent certain types of cancers and reduce the risk of heart disease. Ounce per ounce, almonds have as much calcium as milk.
