Recent recommendations for Americans aged 2 and older call for a reduction in the average saturated fat intake to less than 10% of calories.
Using 24-hour dietary recalls collected from mothers of 4- to 7-year-old urban Latino children, we identified foods and dietary behavior patterns that distinguish children with higher and lower mean daily percentages of calories from saturated fat.
Compared with children in the lowest quintile of intake, children in the highest quintile consumed more than twice as much saturated fat per day from high-fat milk products (18.5 g vs 7.8 g), mostly from whole milk. They did not consume different kinds of milk or different amounts of milk per eating occasion, but on average they consumed milk more frequently (2.8 vs 1.6 eating occasions per day). Even children in the lowest quintile, on average, exceeded the 10% of calories from saturated fat currently recommended. If low-fat (1% fat) milk had been substituted without other dietary changes, all but the highest two quintiles would have been within the recommended level.
The substitution of low-fat for whole milk appears to be a key strategy for preschool children for achieving recommended levels of saturated fat intake.
最近针对2岁及以上美国人的建议呼吁将平均饱和脂肪摄入量降低至热量的10%以下。
通过收集4至7岁城市拉丁裔儿童母亲的24小时饮食回忆,我们确定了区分每日饱和脂肪热量平均百分比较高和较低的儿童的食物及饮食行为模式。
与摄入量最低五分位数的儿童相比,最高五分位数的儿童每天从高脂肪奶制品中摄入的饱和脂肪量是前者的两倍多(18.5克对7.8克),大部分来自全脂牛奶。他们在每次用餐时饮用的牛奶种类和数量并无差异,但平均而言,他们饮用牛奶的频率更高(每天2.8次用餐对1.6次用餐)。即使是摄入量最低五分位数的儿童,平均而言也超过了目前建议的饱和脂肪热量的10%。如果在不改变其他饮食的情况下用低脂(1%脂肪)牛奶替代,除了最高的两个五分位数外,其他所有儿童都将处于建议水平之内。
用低脂牛奶替代全脂牛奶似乎是学龄前儿童实现饱和脂肪摄入建议水平的关键策略。
