Review Measure

Essential Measures are only those items that are critical to the collection of the Measure or are necessary for the interpretation of results. Essential Measures are integral to the Measure. Without such information the data collected would be incomplete and/or misleading.
An additional PhenX Measure that the user may find helpful based on the selection of a particular PhenX Measure. Related PhenX Measures can include additional Measures that are needed to calculate a Derived Variable (e.g., Weight and Height are needed to calculate BMI), Measures that are commonly used in presentations and publications to present the value of the chosen Measures (e.g., Height and Weight by Race and Ethnicity), Measures that are conceptually related to the chosen Measure (e.g., Current Educational Attainment is conceptually related to Annual Family Income and Arm Span is conceptually related to Height), Measures that are physiologically and/or biologically related to the chosen Measure (e.g., Stroke and Heart Disease). Related PhenX Measures are suggestions only.
The Collections are an alternative to the research domains for browsing the PhenX Measures. Measures that are related by a specific topic are grouped together.

Measure: Fiber Intake   #050600


A measure to estimate an individual’s daily average intake of fiber over the last 30 days as measured in grams.


The Institutes of Medicine (IOM) set an Adequate Intake (AI) for Total Fiber in foods at 38 and 25 grams/day for young men and women respectively, based on the intake level observed to protect against coronary heart disease. Fiber decreases the absorption of fatty acids and cholesterol from the gut and may also reduce postprandial blood glucose concentrations and potentially have a beneficial effect on insulin sensitivity.
