Food components are expressed in kilocalories/person/day, such that each row displays the impact on diabetes prevalence of a 1 kilocalorie/person/day increase in the availability of the given food category (e.g., a 1 kilocalorie/person/day rise in sugar relates to a 0.0072% rise in diabetes prevalence). Urbanization refers to the percentage of the population living in urban areas. Aging is the percentage of the population 65 years of age and older. Obesity is the percentage of the population with BMI at least 30 kg/m2.
