Notes: Numbers of countries range 171–175. All food group variables and calories from the FAO, meat and CHO (abbreviated for carbohydrates including cereals, starchy root and sugars) are expressed in g/capita/day; total calories is expressed in kcal/capita/day, GDP PPP is in per capita USD per year; URBAN is expressed in percentage of population living in urban area; BMI 30 kg/m² is expressed with percentages of defined population with a body mass index (BMI) of no less than 30 kg/m².
