Diet 

There are three types of nutrient and dietary data (nutrients, items and My Pyramid Equivalents Database 2.0 (MPED) components) posted to the WHI website.  All three types of nutrient and dietary data are from the Food Frequency Questionnaire (FFQ) – Form 60.  Dietary quality indices, based on these three data types, are available at the 'Download Data' page and summarized below. WHI FFQ data for nutrients, items, MPED components and dietary quality indices data are available for investigator use upon approval for WHI papers or ancillary studies.

Nutrients, Items, MPED components

  1. Nutrients

  2. Items

  3. My Pyramid Equivalents Database 2.0 (MPED)

The United States Department of Agriculture (USDA) MPED 2.0 (MPED) includes 32 per 100 grams equivalent food grouping measures.  The MPED components are the building blocks of many dietary pattern scoring systems, such as but not limited to, the Healthy Eating Index 2005 (HEI-2005), HEI-2010, HEI-2015.  The HEI-2005, HEI-2010 and HEI-2015 scores are based on the USDA 2005, 2010 and 2015 Dietary Guidelines for Americans, respectively.  The MPED components are based on dietary assessment data from the National Health and Nutrition Examination Survey (NHANES) nutrition component, What We Eat in America.

Dietary Quality Indices

Several dietary quality indices have been computed from the MPED components and FFQ nutrients.  See below for ReadMe files with details about the computations.  For the aMed and DASH, scores are dependent on the analytic sample, and thus for these two indices SAS code and computational instructions are provided and not the data.  The data can be downloaded from the Download page by investigators with approved access and logins.
