Data from 185 countries indicated that mean animal-source foods (ASF) intake was 1.9 servings per day. Intake was similar between boys and girls but higher among urban children with educated parents. Consumption varied by age from 0.6 servings for children under age 1 to 2.5 servings per day for those ages 15–19. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week in all regions except sub-Saharan Africa.
