Introduction The goals of a diet for the first year o life and ablacting are to provide and adequate energy intake for the accelerated growth and development of this phase of life, as well as to establish solid eating habits. The rhythm of physical growth that takes place during the first weeks of postnatal life is not comparable at all to that of the normal healthy subjects of other ages and this high rate of growth exercises a great impact on nutritional requirements. At the beginning a substantial part of energy and other essential nutrients needs, are used in the formation of new tissue (growth). Toward the 4^th month of age, the healthy normal infant has duplicated its weinght, and the tissue formation rhythm has decreased enormously; therefore, its global needs for energy and nutrients are used in a great less percentage for the synthesis of new tissue. The nutrients that and infant needs, by unit of corporal size, since the 8^th month of age till the year of age are more similar to those needed by preschool children, more that to those required by the infant from birth to its 4^th month of age.
