Olive oil : its history and health benefits

Olive oil originated in the Mediterranean region, where it has been produced for thousands of years. The first traces of olive oil use date back to antiquity, when it was used for cooking, skin care and religious rituals. Olive groves were cultivated in Egypt, Greece and Rome, and olive oil was considered a luxury product.

Over the centuries, olive oil became a staple in Mediterranean regions, used for cooking, folk medicine and lighting. The Romans developed methods for extracting olive oil, which have been perfected over the centuries.

Olive oil has also played an important role in the region's economic history, being exported to other countries since the Middle Ages. Olive products are also important in regional culture and traditions, such as All Saints' Day in Provence, when people go to olive groves to bless the trees and crops.
