We have calculated that the approximate amount of the different water intakes for an average adult population consuming 11.8 MJ/day (2,837 kcal/day), where 1.4 MJ (337 kcal) are provided by beverages, is 2.7 liter/day. These intakes include: 'invisible intakes' supplied by endogenous water (348 ml/12.9%) and water contained in food, fruit or dairy products (1,008 ml/37.6%), and 'visible intakes' provided by water contained in commercialized beverages such as bottled water, fruit juices, sodas, fruit drinks, alcoholic drinks (678 ml/25.3%) and tap water (estimate/650 ml/24.2%). We advise to carry out consumption studies according to the various age brackets.
