Increase potassium consumption by people aged 2 years and over — NWS‑14 Data Methodology and Measurement

About the National Data


Baseline: 2,517 milligrams (mg) of potassium from food and dietary supplements was the mean total daily intake by persons aged 2 years and over in 2013-16

Target: 2,769 mg

Sum of daily intake of potassium (in mg) among persons aged 2 years and over.

Target-setting method details
10 percent improvement from the baseline.
Target-setting method justification
Trend data were not available for this objective. A 10 percent improvement from the baseline was used to calculate a target. This method was used because based on data from the United States Department of Agriculture's (USDA) What We Eat in America, there has been little or no change in potassium intake from food and dietary supplements for the United States population aged two and older in the last six years.


Methodology notes

To determine total potassium intake, several sources of potassium were considered, including foods and dietary supplements. The NHANES food consumption data included the collection of 1 day of dietary data for all respondents through in-person 24-hour recalls and collection of a 2nd-day 24-hour recall by telephone. Both dietary recalls are obtained by trained dietary interviewers using USDA's Automated Multiple Pass Method (AMPM). For these analyses, potassium intake from only the first 24-hour recall will be used. Each respondent was asked to recall the kinds and amounts of foods and beverages consumed at home and away from home during the previous day (midnight to midnight). Amounts of foods and beverages reported in household measures were then converted to gram amounts, and potassium intake from foods and beverages was estimated with the use of food composition files.

Breast-feeding children were excluded from the analysis.


Revision History

In 2022, the baseline was revised from 2,512 to 2,517 due to a change in participant exclusion criteria for consistency with the analyses for food and nutrient intake objectives that were retained from HP2020. The target was revised from 2,763 to 2,769 using the original target setting method.
