Olive, the fruit of the olive tree, has been a cornerstone of human nutrition and culture for millennia. Not only are olives a staple in many cuisines around the world, but they also boast an impressive array of health benefits due to their rich nutritional content. From antioxidants and healthy fats to a myriad of essential vitamins and minerals, olives are truly a nutritional powerhouse. In this article, we will delve into the composition of olives, exploring what they contain and why these components are so beneficial for our health.
Introduction to Olives
Olives are the fruit of the olive tree (Olea europaea), native to the Mediterranean region. They are typically green or black, depending on their stage of ripeness, with green olives being picked before they are fully ripe and black olives being allowed to ripen on the tree. The process of curing or pickling olives makes them edible, as fresh olives are extremely bitter due to their high oleuropein content.
