A recent study by strategic consultants Juan Vilar has revealed that San Marino is the world's largest consumer of olive oil, with per capita consumption of almost 22 kg per year. The study covered 198 countries that consume olive oil, 92% of which are located where the olive tree grows. The annual per person consumption of olive oil globally is 450 grams, with Greece, Spain, and Italy following San Marino as the top per capita consumers. Iceland, a non-producer, rounded out the top five with a per capita consumption of 5.8 kg per year.
