In 1758, Swedish scientist Eva Ekeblad revolutionized the economy and agricultural practices with her innovative use of potatoes. Previously ornamental, potatoes became a staple through Ekeblad's method of converting them into flour and alcohol. This breakthrough enhanced food sustainability, alleviating grain shortages and improving agricultural productivity. Her work contributed to economic stability by promoting efficient land use and transforming dietary habits in Sweden, thus marking a significant advance in 18th-century food science.
