Concern has been raised about the energy and nutrient adequacy of low fat diets for children that aim to prevent cardiovascular disease in Western populations. The diets of 174 randomly chosen schoolchildren aged 8-12 years from middle and high socioeconomic groups were analysed to determine their nutrient composition in relation to fat intake. The mean percentages of energy intake from fat and saturated fat were 31 and 13%, respectively, and 44% of all children reported consuming < 30% of their energy from fat. The energy intake did not change across the spectrum of fat intake. A decreased fat intake was associated with an increased sugar intake, but also with increased nutrient densities of thiamin, niacin, folate, vitamin C, magnesium, and iron, reflecting an increased intake of fruit, vegetables, and grains. Parental educational level was the most important determinant of fat intake (inverse relation). It is concluded that a self selected low fat intake among children from average to high socioeconomic backgrounds does not compromise their intake of major nutrients or energy.
对于西方人群中旨在预防心血管疾病的儿童低脂饮食的能量和营养充足性,人们已提出担忧。对174名随机选取的8至12岁来自中等和高社会经济群体的学童饮食进行分析,以确定其营养成分与脂肪摄入量的关系。脂肪和饱和脂肪的能量摄入平均百分比分别为31%和13%,且44%的儿童报告其脂肪能量摄入量低于30%。能量摄入在脂肪摄入范围内并无变化。脂肪摄入量减少与糖摄入量增加相关,但也与硫胺素、烟酸、叶酸、维生素C、镁和铁的营养密度增加相关,这反映出水果、蔬菜和谷物的摄入量增加。父母的教育水平是脂肪摄入量的最重要决定因素(呈负相关)。得出的结论是,来自平均至高社会经济背景的儿童自行选择的低脂肪摄入量不会损害其主要营养素或能量的摄入。
