Our Data Source
USDA National Nutrient Database (SR28)
OkFood uses the authoritative food composition database compiled by the U.S. Department of Agriculture. This is the same foundational data used for nutrition facts labels across the United States.
How We Calculate Your Needs
Calories
Using the Mifflin-St Jeor equation, recommended by the Academy of Nutrition and Dietetics for its accuracy. Your base metabolic rate is adjusted for activity level and, for women, pregnancy or lactation status.
Macronutrients
Based on established dietary guidelines:
Vitamins & Minerals
From Dietary Reference Intakes (DRI) established by the National Academies of Sciences, Engineering, and Medicine. Values are adjusted for your age and gender.
Important Things to Know
Nutrient Values Are Averages
The numbers you see represent typical values. Actual nutrient content varies based on growing conditions, season, brand, preparation method, and storage. Use the data as a helpful guide, not an exact measurement.
Five Nutrients Have No Data
These nutrients appear in the app but aren't measured in the USDA database. When you see 0%, the data simply isn't available - it doesn't mean the food lacks them.
| Nutrient | Why It Matters |
|---|---|
| Biotin (B7) | Metabolism, hair and nail health |
| Chloride | Fluid balance, digestion |
| Iodine | Thyroid function |
| Chromium | Blood sugar regulation |
| Molybdenum | Enzyme activity |
For iodine, good sources include iodized salt, seaweed, fish, and dairy products.
Recommendations Are Estimates
Your personalized daily values are based on population-level research. Individual needs vary based on metabolism, health conditions, genetics, and actual activity levels. For specific dietary guidance, consult a healthcare professional.
This Is Educational, Not Medical Advice
OkFood is designed to inform and educate. It's not a substitute for professional nutritional counseling, especially if you have health conditions, take medications, or have specific dietary requirements. Always consult healthcare professionals for personalized advice.
