Abstract

INTRODUCTION

Recent population-based studies reported an inadequate dietary intake of creatine, a conditionally essential nutrient that plays an important role in human metabolism.

METHODS

We analyzed here the nutritional profiles of US adults with low creatine consumption, using data from the 2017 to 2018 National Health and Nutrition Examination Survey (NHANES).

RESULTS

Among 4,004 NHANES adult participants that reported detailed dietary intake information, 2,611 (65.2%) were calculated to have dietary creatine intake below recommended levels of 1.00 g/day. The average daily creatine intake in this subpopulation was 0.52 ± 0.26 g (95% confidence interval, from 0.51 to 0.53). This was accompanied by a significantly lower dietary intake of meat-based protein, as compared to participants whose dietary creatine intake was equal to or above recommended levels (20.1 ± 10.2 g/day vs. 67.1 ± 30.4 g/day; p < 0.001).

CONCLUSION

The large-scale rate of suboptimal dietary creatine intake found in this cross-sectional study warrants additional research, and calls for immediate public health measures fostering creatine-rich foods in human nutrition.

摘要

简介

最近的基于人群的研究报告称，人体对肌酸的日常饮食摄入量不足，肌酸是一种条件必需营养素，在人体新陈代谢中起着重要作用。

方法

我们利用 2017 至 2018 年全国健康和营养调查（NHANES）的数据，分析了美国肌酸摄入量低的成年人的营养状况。

结果

在报告详细饮食摄入信息的 4004 名 NHANES 成年参与者中，有 2611 名（65.2%）被计算为日常饮食中肌酸摄入量低于推荐水平 1.00 g/天。在这个亚人群中，平均每日肌酸摄入量为 0.52 ± 0.26 g（95%置信区间为 0.51 至 0.53）。与饮食中肌酸摄入量等于或高于推荐水平的参与者相比，他们的饮食中肉类蛋白质的摄入量明显较低（20.1 ± 10.2 g/天比 67.1 ± 30.4 g/天；p < 0.001）。
