A delicious snack enjoyed all over the world, olives are versatile and nutritious. They can be eaten alone as a snack, as part of an appetizer charcuterie board or included in recipes. And, of course, when olives are pressed into extra virgin olive oil, they become even more versatile.

National Olive Day is the ideal time to appreciate and enjoy everything related to this little fruit that packs a big punch in flavor and nutrition.

History of National Olive Day

Olives have a rich and deep history, and they have been appreciated in many cultures over time. These little fruits are believed to have originated in Asia Minor and then spread through Palestine, Iran and Syria to the Mediterranean region where they found a home at least 6000 years ago.

The olive tree is one of the oldest cultivated trees in the world and its fruit, as well as the oil that comes from it, has been beloved and revered for several millennia. Not only is olive a healthy oil for cooking and eating, many people like to include it as an ingredient in their skin care and beauty regimens because of its healthful properties.

All dotted throughout Spain, Greece, Italy, and Turkey, groves of olive trees bring olives which are often eaten on their own or pressed into extra virgin olive oil. Olives are a huge industry worldwide and the demand for table olives continues to grow all over the globe. More than 500 different varieties of olives are cultivated today, with all sorts of different flavors and even unique colors.

National Olive Day was founded in 2015 by Divina, an arm of the FOODmatch specialty Mediterranean foods company that is located in the United States. It was decided that Olive Day should be placed on the first day of June as a finale to the end of May, which is a month when some people celebrate the Mediterranean Diet.
