Notes: Intakes are reported in grams per day (g/d) for all dietary factors. Intakes are based on modelled estimates for adults aged 25 years and older. The dietary factors have been selected as those diet components that have a statistically significant relationship with at least one disease endpoint that can be generalisable to all populations. Recommended intake targets were determined by the EAT-Lancet Commission on healthy diets from sustainable food systems. This includes minimum recommended intakes of health promoting food groups (fruits, vegetables, legumes, nuts and wholegrains) and maximum recommended intakes of food groups with detrimental health and/or environmental impacts (red meat, dairy, and fish). Ideal intake for each food is within the shaded area of the graph.

Overweight is defined as above one standard deviation (>+1 SD) from the median weight-for-height of the WHO growth reference.

Notes: Prevalence (%) estimates are based on modelled age-standardised estimates for adults aged 18 years and older from 2000 to 2015 for raised blood pressure, and from 2000 to 2014 for diabetes, using the WHO standard population. Projected values for 2019 are displayed using a dashed line.

Notes: Deaths (in millions) attributable to dietary risk factors by cause of death, for risks related to dietary composition and weight levels. The combined risk is less than the sum of individual risks because individuals can be exposed to multiple risks, but mortality is ascribed to one risk and cause. 'All risk factors' includes all deaths associated with dietary composition (i.e. diets low in fruits, diets low in vegetables, diets low in wholegrains, diets high in processed meat, diets high in red meat, and diets high in sugary drinks) and all deaths associated with weight levels (i.e. underweight, overweight, obese). See Methodology for more information on the indicators.

Notes: Prevalence (%) is calculated from three-year averages of modelled estimates, with the associated year being the middle year of those three (e.g., 2018 estimate is the average of 2017–2019). The prevalence of undernourishment is defined as the proportion of the population whose habitual food consumption is insufficient to provide the dietary energy levels required to maintain a normal active and healthy life. Due to estimation limitations, low undernourishment prevalence below 2.5% can not be accurately represented. For visualisation, we have presented these as 2.4 where relevant.

Notes: Number of health workers per 1,000 people, based on modelled estimates. Health worker definition and training vary across countries and human resources tend to be concentrated in urban areas, so inferences may be affected. Medical doctors include generalist and specialist medical doctors. Nurses and midwives include professional, auxiliary and enrolled nurses and midwives, as well as other associated personnel, e.g. dental and primary care nurses. Community health workers include various types of community health aides, many with country-specific occupational titles such as community health officers, community health-education workers, family health workers, lady health visitors and health extension package workers.

Source: New analysis based on estimates of food demand from the Food and Agriculture Organization (FAO) (FAO. Food Balance Sheets: A Handbook. Rome, Italy: FAO, 2001) and a database of country- and food group-specific environmental footprints (Springmann et al. Nature 2018; 562: 519–25; Poore & Nemecek. Science 2018; 360: 987–92).

Notes: Data on food demand for each country from FAO was paired with a comprehensive database of environmental footprints, differentiated by country, food group, and environmental impact. The footprints take into account all food production, including inputs such as fertilisers and feed, transport, and processing, e.g., of oil seeds to oils and sugar crops to sugars. The displayed total pressure is in the units stated for each environamental domain and has been rounded to the nearest 10 units. See Methodology for more information on the indicators.

The target values for sustainable food production are in line with Sustainable Development Goals specified by and adapted from the EAT-Lancet Commission (Willett et al.The Lancet 2019; 393: 447–92.; Springmann et al. The British Medical Journal 2020; 370: 2322).

Notes: Planetary boundaries define the threshold related to global environmental processes beyond which humanity should not go. Planetary boundaries align with the targets for sustainable food production as set out by the Sustainable Development Goals. If impacts exceed 100% of the planetary boundary, the dietary pattern of that particular region or country can be considered unsustainable in light of global environmental targets, and disproportionate in the context of an equitable distribution of environmental resources and mitigation efforts.
