Health at a Glance 2021
OECD Indicators
Health at a Glance provides a comprehensive set of indicators on population health and health system performance across OECD members and key emerging economies. These cover health status, risk factors for health, access to and quality of health care, and health resources. Analysis draws from the latest comparable official national statistics and other sources.
Alongside indicator-by-indicator analysis, an overview chapter summarises the comparative performance of countries and major trends. This edition also has a special focus on the health impact of COVID-19 in OECD countries, including deaths and illness caused by the virus, adverse effects on access and quality of care, and the growing burden of mental ill-health.

Diet and physical activity among adults
A healthy diet is associated with improved health outcomes. Adults who follow a diet rich in fruit and vegetables and low in fat, sugars and salt/sodium are at a lower risk of developing one or more cardiovascular diseases and certain types of cancer (Graf and Cecchini, 2017[21]). A healthy diet may also reduce the likelihood of being overweight or obese. In 2019, diets low in fruit, vegetables and legumes were responsible for an estimated total of 2.7 million deaths worldwide (Institute for Health Metrics and Evaluation, 2020[22]).
