The Liq.in7 interactive map has been developed based on evidence from large population surveys conducted in a harmonized way across the three continents (e.g. Europe, South America and Asia).
You can use the map to find information on the intake of different kinds of fluids across countries and the recommended values of total fluid intake (mL/day) by each country.
You can find more information about the methodology of developing the map at this link.
The map was developed by hydration experts of Danone NutriciaResearch.
