通过补充养减少婴儿蛋白质摄入量,就像北欧饮食一样,可以降低分支链氨基酸 (BCAA) 并减轻体重增加,这是预防儿童肥胖的一个关键因素.
科学领域:
- 代谢研究和营养科学.
- 儿童营养和预防肥胖.
背景情况:
- 婴儿期高蛋白摄入量与肥胖风险增加有关.
- 资源丰富的国家经常看到蛋白质消费超过建议.
研究的目的:
- 分析婴儿对减少蛋白质的北欧饮食的代谢反应与传统饮食的代谢反应.
- 通过将蛋白质摄入量与BCAA,IGF-1和使用SEM的生长结果联系起来,来测试早期蛋白质假设.
主要方法:
- 一个随机对照试验的二次分析,其中包括250名婴儿.
- 12个月和18个月的血代谢量 (1H-NMR).
- 结构方程建模 (SEM) 来评估蛋白质摄入量,代谢物和生长之间的关系.
主要成果:
- 北欧饮食组的蛋白质摄入量较低,血代谢概况不同.
- 减少蛋白质摄入与循环BCAA的降低有关,并与IGF-1水平呈正相关.
- 累积蛋白质摄入量在考虑到代谢物效应后仍然与婴儿体重有显著的关联.
结论:
- 婴儿补充养显著影响了血代谢.
- 在补充养期间降低蛋白质摄入量可以减少婴儿快速体重增加.
- 这种干预措施可能有助于缓解以后肥胖的早期预测因素.
