The cost of a nutrient adequate diet is the lowest-cost set of foods available that would meet nutritional requirements of calories, protein, fats and all essential vitamins and minerals. A diet is defined as unaffordable when its cost, plus basic non-food needs like housing and transportation, exceeds daily income.

Both metrics indicate that someone does not get enough food (in terms of calories) to eat: these metrics should be strongly correlated. Severe food insecurity is measured based on food security questionnaires among households. Undernourishment is based on estimates of actual calorie intake across the population.

Daily supply of protein from animal-based vs. plant-based products, measured as the average supply in grams per person per day. Protein of animal origin includes protein supplied in the form of all meat commodities, eggs and dairy products, and fish and seafood. Countries that lie above the grey line source a higher proportion of protein from animal-based than plant-based foods.

The protein efficiency of meat and dairy production is defined as the percentage of protein inputs as feed effectively converted to animal product. An efficiency of 25% would mean 25% of protein in animal feed inputs were effectively converted to animal product; the remaining 75% would be lost during conversion.

Daily calorie supply of animal protein includes protein sources from animal-based foods including meat, dairy and seafood products. This is shown against mean male height in adults by year of birth.

Share of cereals available for domestic consumption – after accounting for trade – that is allocated to other purposes (primarily industrial uses such as biofuel production), relative to the total allocated to human food, animal feed, and other uses. This excludes cereals used for seed, processing, and losses.

Agricultural value added per worker is calculated by dividing the amount of economic value generated from farming, forestry and fishing by the number of people who work in these sectors. This data is expressed in US dollars. It is adjusted for inflation but does not account for differences in living costs between countries.
