Polyphenol Estimator

Polyphenol Estimator provides polyphenol intake summaries at three different resolution levels: total, class, and compound. Click the headings below to examine various outputs:

Total Polyphenol Intake
  • Diet_total_nutrients.csv: Nutrient totals are provided by entry (recall or record and record day) for each participant
  • summary_total_intake_by_entry.csv: polyphenol total intakes by entry (recall or record and record day) for each participant
  • summary_total_intake_by_subject.csv: polyphenol total intakes for each participant
  • summary_total_polyphenol_food_contributors.csv: total polyphenol and intake averages for each food, as well as food frequencies
Class Polyphenol Intake
  • summary_class_by_entry.csv: polyphenol class intakes by entry (recall or record and record day) for each participant
  • summary_class_by_subject.csv: polyphenol class intakes for each participant, provided in long format (classes as rows)
  • summary_class_by_subject_wide.csv: polyphenol class intakes for each participant, provided in wide format, i.e. classes as columns
Compound Polyphenol Intake
  • summary_compound_by_entry.csv: polyphenol compound intakes by entry for each participant
  • summary_compound_by_subject.csv: polyphenol compound intakes for each participant, provided in long format (compounds as rows)
  • summary_compound_by_subject_wide.csv: polyphenol compound intakes for each participant, provided in wide formal, i.e. compounds as columns
Unmapped Foods (i.e. What didn't map to FooDB?)
  • summary_missing_foods_overview.txt: Summary of the number of unmapped foods between FDA-FDD and FooDB across ALL recalls or records and record days
  • summary_missing_foods_detailed.csv: Summary of the number of unmapped foods between FDA-FDD and FooDB BY recall or record and record day
Intermediate Files Our mapping output files are large feature-rich datasets, which we have compressed.
  • Diet_Disaggregated.csv.bz2: Food codes are shown with their underlying ingredients and newly calculated gram intakes
  • Diet_Disaggregated_mapped.csv.bz2: Food codes are shown with their underlying ingredients and newly calculated gram intakes, and FooDB food name equivalent (no content)
  • Diet_FooDB_polyphenol_content.csv.bz2: Food codes are shown with their underlying ingredients and newly calculated gram intakes, and FooDB food names. Contains polyphenol content.
Log Files A log file is also generated for each run of estimate_polyphenols() and calculate_DII(). These files are intended to help users track use and time of Polyphenol Estimator runs, including any runs that experienced an error.

Dietary Inflammatory Index (DII) Calculation

We have one output file:

  • summary_DII_final_scores_by_entry.csv: Total 42-component DII scores as well as all 42 individual component scores.
Intermediate Files Intake summary files for the 14 food and polyphenol components are fed into the total DII calculation.
  • Diet_DII_eugenol_by_entry.csv: Eugenol intake by entry (recall or record and record day)
  • Diet_DII_foods_by_entry.csv: Food intake (onion, ginger, garlic, tea, pepper, turmeric, thyme/oregano) by entry (recall or record and record day)
  • Diet_DII_subclass_by_entry.csv: Polyphenol subclass intake (flavan-3-ols, Flavones, Flavonols, Flavonones, Anthocyanidins, Isoflavones) by entry (recall or record and record day)
