青春期是人类发展的一个关键而复杂的阶段,其特征是重大的生物,心理和社会变化。青春期标志着身体加速生长、身体成分改变和性成熟的开始。女性青少年的生长突增对成人身高的贡献约为16%,对成人体重的贡献约为54%,对成人体脂含量的贡献约为73%,对成人瘦体重的贡献约为40%,对全身钙的贡献约为37%(图1)。男性也有类似的变化。所有人在这一时期的生活应该是在一个强大的积极氮平衡和平衡的矿物质所需的身体建设。这些变化影响了青少年的营养需求和状况(图2)。此外,心理变化,包括青少年的独立性和身份的搜索,被同龄人接受的愿望,并与外观的关注可能会影响饮食习惯,食物的选择,营养摄入量,特别是某些矿物质的状态,其中钙(Ca),磷(P),镁(Mg),铁(Fe),锌(Zn),硒(Se)是最重要的。在过去的20年里,营养研究和儿童建议的重点已经从预防营养缺乏转向早期建立推荐饮食以预防慢性疾病。这些优先事项最终可能导致通过针对生命早期易感个体来预防和治疗这些疾病的饮食指南(3)。
Adolescence is a critical and complex phase in human development characterized by major biological, psychological, and social changes. Puberty marks the beginning of accelerated physical growth, alterations in body composition, and sexual maturation. The growth spurt in female adolescents contributes about 16% to adult height, 54% to adult weight, 73% to adult body fat content, 40% to adult lean body mass, and about 37% to the whole body calcium (Fig. 1). Similar changes are present in males. All individuals during this period of life should be in a strong positive nitrogen balance and balance of minerals required for body building. Those changes influence teenagers’ nutritional needs and status (Fig. 2). In addition, psychological changes involving the adolescent’s search for independence and identity, desire for acceptance by peers, and preoccupation with physical appearance may affect eating habits, food choices, nutrient intake, and particularly status of certain minerals of which calcium (Ca), phosphorus (P), magnesium (Mg), iron (Fe), zinc (Zn), and selenium (Se) are the most important. During the last 20 years, the focus of nutrition research and recommendations for children has shifted from the prevention of nutritional deficiencies to the early establishment of recommended diets to prevent chronic diseases.These priorities may eventually lead to dietary guidelines for the prevention and treatment of those conditions by targeting predisposed individuals early in life (3).
