Abstract：
The teenage years represent a crucial period of physical and cognitive growth and development with sufficient micronutrient intakes necessary to meet high nutritional requirements. This review examines current micronutrient intakes in teenagers in the Western world in the context of public health implications including the prevalence of inadequate intakes and risk of excessive intakes. Intakes of vitamins A, D, E and C, folate, calcium, iron, magnesium, zinc and potassium in teenagers are low when compared to generally accepted recommendations, while there is little risk of excessive micronutrient intakes based on current dietary patterns. Therefore, strategies should focus on increasing micronutrient intakes in order to decrease the risk of negative impacts resulting from these low intakes. These strategies should be mindful of guidance towards an environmentally sustainable diet whilst ensuring that nutrient intakes in teenagers are not further negatively impacted. In order to identify, implement and monitor the effectiveness of such strategies, intakes of micronutrients should be continually monitored in nationally representative samples of the population for all age groups including this vulnerable cohort of teenagers.
摘要：
青少年时期是身体和认知生长和发育的关键时期，需要足够的微量营养素摄入量来满足高营养需求。这篇评论在公共卫生影响的背景下研究了西方世界青少年当前的微量营养素摄入量，包括摄入量不足的患病率和过量摄入的风险。维生素A的摄入量，D,E和C,叶酸,钙，铁,镁，锌，与普遍接受的建议相比，青少年的钾含量较低，而根据目前的饮食模式，微量营养素摄入量过多的风险很小。因此,战略应侧重于增加微量营养素的摄入量，以降低这些低摄入量造成负面影响的风险。这些策略应注意对环境可持续饮食的指导，同时确保青少年的营养摄入量不会受到进一步的负面影响。为了识别,实施和监测这些战略的有效性，应该在全国代表性的所有年龄组的人群样本中持续监测微量营养素的摄入量，包括这个脆弱的青少年群体。
