There is concern that added sugar may dilute micronutrients and displace nutrient dense foods from the diet.
The data for this analysis was based on the National Children's Food Survey and National Teen Food Survey, which used 7-day food diaries to collect food and beverage intake data in representative samples of Irish children (5-12 years, n = 594) and teenagers (13-17 years, n = 441) respectively.
High consumption of added sugars was associated with a decrease in the micronutrient density of the diet and increased prevalence of dietary inadequacies in children and teenagers. The decrease in micronutrient density was significant for several micronutrients, including magnesium (P < 0.001), calcium (P < 0.01 children; P < 0.001 teenagers), zinc (P < 0.05) and vitamins B(12) (P < 0.01 children; P < 0.001 teenagers) and C (P < 0.05). There was wide variation in the micronutrients for which prevalence of dietary inadequacies increased depending on gender and population group.
Clinical data are required before conclusions can be made on whether micronutrient dilution is a concern in Ireland. A change in the consumption of several foods across level of added sugar intake may explain the decrease in the intake of several micronutrients and the decrease in the compliance with macronutrient recommendations in high consumers of added sugars in children and teenagers.
人们担心添加糖可能会稀释微量营养素,并将营养丰富的食物从饮食中取代。
本分析的数据基于全国儿童食品调查和全国青少年食品调查,这两项调查分别使用7天食物日记,在爱尔兰儿童(5 - 12岁,n = 594)和青少年(13 - 17岁,n = 441)的代表性样本中收集食物和饮料摄入数据。
高添加糖摄入量与儿童和青少年饮食中微量营养素密度降低以及饮食不足患病率增加有关。几种微量营养素的微量营养素密度降低显著,包括镁(P < 0.001)、钙(儿童P < 0.01;青少年P < 0.001)、锌(P < 0.05)以及维生素B12(儿童P < 0.01;青少年P < 0.001)和维生素C(P < 0.05)。根据性别和人群组的不同,饮食不足患病率增加的微量营养素存在很大差异。
在就微量营养素稀释在爱尔兰是否是一个问题得出结论之前,需要临床数据。儿童和青少年中高添加糖消费者几种食物摄入量随添加糖摄入量水平的变化,可能解释了几种微量营养素摄入量的减少以及对宏量营养素建议的依从性降低。
