Polyphenol Estimator
Polyphenol Estimator can work with ASA24 Record Items Files, ASA24 Recall Items Files, or NHANES “Individual Foods” Recall Files. Based on the data input (ASA24 vs NHANES), STEP 1 will differ but STEP 2 and STEP 3 are the same.

Steps Specific to ASA24
- STEP1_ASA24_FDD_Disaggregation.Rmd
- For provided ASA24 data, WWEIA food codes are disaggregated to ingredients. A new ingredient amound is calculated based off percentages included in the FDA’s Food Dissagregation Database. Total nutrient intake is also calculated across recalls or records for later standardization of polyphenol intake.
Steps Specific to NHANES
- STEP1_NHANES_FDD_Disaggregation.Rmd
- For provided NHANES data, WWEIA food codes are disaggregated to ingredients. A new ingredient amound is calculated based off percentages included in the FDA’s Food Dissagregation Database. Total nutrient intake is also calculated across recalls or records for later standardization of polyphenol intake.
Steps used on both ASA24 and NHANES
- STEP2_FDD_FooDB_Content_Mapping.Rmd
- Connects each of your disaggregated ASA24 Foods to their equivalent food description in FooDB so that polyphenol intake can be estimated.
- Provides summary information about the number of foods in your data that did not map to FooDB.
- STEP3a_Polyphenol_Summary_Total.Rmd
- Calculates total polyphenol intake (mg, mg/1000kcal) for each recall or record as well as an overall subject summary.
- STEP3b_Polyphenol_Summary_Class.Rmd
- Calculates class polyphenol intake (mg, mg/1000kcal) for each recall or reecord as well as an overall subject summary.
- STEP3c_Polyphenol_Summary_Compound.Rmd
- Calculates compound polyphenol intake (mg, mg/1000kcal) for each recall or record as well as an overall subject summary.
- STEP3d_Polyphenol_Summary_Food_Contributors.Rmd
- Examines food contributors to total polyphenol intake.
