Therefore, the recommended amount, which is also promoted by the European Food Safety Authority, “is not supported by the research data”, the study authors said.
In addition, the researchers also concluded that the total movement of the body’s intake and loss of water is greater in hot and humid environments, as well as at high altitudes.
