Protein intake is more stable than carbohydrate or fat intake across various US demographic groups and international populations.

ABSTRACT:

Background

The optimal macronutrient composition of the diet is controversial and many adults attempt to regulate the intake of specific macronutrients for various health-related reasons.

Objective

The objective was to compare stability and ranges of intakes of different macronutrients across diverse adult populations in the USA and globally.

Methods

US dietary intake data from NHANES 2009-2014 were used to determine macronutrient intake as a percentage of total energy intake. Variability in macronutrient intake was estimated by calculating the difference between 75th and 25th percentile (Q3-Q1) IQRs of macronutrient intake distributions. In addition, intake data from 13 other countries with per capita gross domestic product (GDP) over $10,000 US dollars (USD) were us
