乳类在6月龄后的婴幼儿已逐渐不能满足其能量和营养的需要,即需要一食物转换期提供部分能量和营养。食物转换期其他食物的引入不仅提供婴幼儿生长发育所需的能量和营养素,还可锻炼婴幼儿的咀嚼能力以及促进正常嗅觉、味觉的发育,为过渡到固体膳食做准备。其他食物引入的时间、能量和营养、性状、喂养行为因素等会影响儿童生长发育。及时、充足、安全、适宜的食物引入是婴幼儿生长发育的重要保证。
Babies after 6 months of age have gradually been unable to meet their energy and nutrition needs, ie they need a portion of their energy and nutrition during a food conversion period. The introduction of other foods during the food conversion period not only provides the energy and nutrients needed for growth and development of infants and young children, but also exercises the masticatory ability of infants and young children as well as normal olfaction and taste development in preparation for the transition to a solid diet. Other food intake time, energy and nutrition, traits, feeding behavior factors will affect children’s growth and development. Timely, adequate, safe, appropriate food introduction is an important guarantee for the growth and development of infants and young children.
