Figure 1 Reported energy intakes (kJ) for adolescents in a selection of countries.

In the NDNS, mean protein intakes were considerably in excess of requirements, as assessed by RNI, for all ages and both sexes. The main sources were meat and meat products (which contributed 30% of overall protein), cereals, bread, and milk products. It is believed that protein requirements in adolescents are between 0.8 and 1.0 g per kg body mass, although this fails to take into account any additional needs related to regular exercise (which are likely to be minor for most sports and be covered by normal protein intakes). As a proportion of energy, protein intakes were higher in Southern European countries, Australia, and New Zealand compared with intakes in the US and Northern European countries.
