International congress 'Hidden Hunger', March 5-9, 2013, Stuttgart-Hohenheim, Germany.

A greater understanding of how deficiencies manifest themselves and to what extent they are clinically relevant, by sex and age, remains important, and there is a priority need for improved standardization and reporting of measurements (Patrick Webb, Tufts University, Boston, Mass., USA). The FAO (Food and Agriculture Organization of the United Nations) indicators of hidden hunger capture undernourishment but not inadequate intake of essential nutrients. The committee on world food security strongly recommends (October 2011) that the FAO improves its measure of undernourishment with special emphasis on improving the underlying data and parameters including the methodology (Eileen Kennedy, Tufts University, Boston, Mass., USA).
