Rice oil originated in Japan, where people extract the nutrients from rice and refine it into rice oil. For cooking, it's far more nutritious than average cooking oil. Presently, in Japan, rice oil has replaced other conventional cooking oil and has been designated by the Japanese Ministry of Health and Welfare as the dedicated cooking oil in elementary and middle schools to provide students with essential nutrients. The reputation has then spread to the Western developed countries and has been recommended by the American Heart Association (AHA) and the World Health Organization (WHO).
