🍃 USDA/NIH — Dietary Reference Intakes (DRI)

USDA and NIH Dietary Reference Intake values (RDA/AI) for key nutrients by age and sex group. Sets Daily Value (DV) benchmarks for the Nutrient Density Score calculator (iron, calcium, sodium targets) and provides reference context for the Bioavailability calculator (ba-nutrient typical intakes).

Select age group and sex to load USDA/NIH Dietary Reference Intake benchmarks.

Source: USDA/NIH Dietary Reference Intakes. RDA or AI values where RDA not established. FDA Daily Values (2020) used for labeling context.

🍑 USDA FoodData Central — Nutrient Density Reference

USDA FoodData Central nutrient composition per serving for common whole foods. Auto-populates protein, fiber, iron, calcium, calories, sodium, and sugar in the Nutrient Density Score calculator (SF3-S.007) and protein per serving in the Protein Quality calculator (SF3-S.009).

Select food to load USDA FoodData Central nutrient composition for density scoring.

Source: USDA FoodData Central. SR Legacy and Foundation Foods. Values per typical serving size shown.

⚖ Nutrient Gap Analysis

Compares typical US dietary intake against DRI recommendations by demographic group to identify the most common nutrient shortfalls. Based on USDA What We Eat in America (WWEIA) survey data.

Load DRI values first, then click Build Gap Analysis to see most common nutrient shortfalls for your target demographic.

Tip: Use the gap output to identify which nutrients to prioritize in the Nutrient Density Score and Bioavailability calculators above.

๐Ÿฅ— Dietary Reference Intake Calculator

Model SF3-S.006

Calculate personalized DRI values for macronutrients and key micronutrients based on age, sex, activity level.

๐ŸŒพ Whole Grain Nutrient Density Score

Model SF3-S.007

Score nutrient density using Nutrient Rich Foods Index. Compare whole vs refined grain products.

๐ŸŽ Fruit & Vegetable Phytonutrient Index

Model SF3-S.008

Estimate phytonutrient intake from fruit/vegetable servings. Score antioxidant capacity using ORAC values.

๐Ÿฅฉ Protein Quality Score (PDCAAS)

Model SF3-S.009

Calculate protein quality using PDCAAS methodology. Compare animal and plant sources for amino acid completeness.

โš–๏ธ Bioavailability-Adjusted Nutrients

Model SF3-S.010

Adjust nutrient intake for bioavailability. Accounts for food matrix, enhancers, and inhibitors on iron, zinc, calcium.
