How Nutrola Built a 1.8 Million Item Dietitian-Verified Food Database
Nutrola's food database comprises 1.8 million dietitian-verified entries, ensuring nutritional accuracy and reliability for users.
A registered-dietitian-verified food database is a food composition database in which every entry is reviewed by a registered dietitian (RD) for nutritional accuracy before publication, in contrast to crowdsourced databases that publish user-submitted entries with minimal or no professional review. Nutrola's 1.8M-entry food database is built on USDA FoodData Central and EFSA Food Composition Database baselines, expanded with regional foods across 24 languages, and verified entry-by-entry by registered dietitians on the Nutrola nutrition team. No user submissions enter the database without RD review.
What is a registered-dietitian-verified food database?
A registered-dietitian-verified food database is a specialized food composition database. It ensures that each entry is reviewed for nutritional accuracy by a registered dietitian before publication. This contrasts with crowdsourced databases, where user-submitted entries may not undergo professional review.
The verification process enhances the reliability of nutritional information. It provides users with confidence that the data they are using for calorie tracking and dietary planning is accurate.
Why does registered-dietitian verification matter for calorie tracking accuracy?
Registered-dietitian verification significantly impacts calorie tracking accuracy. Studies indicate that self-reported dietary intake often underestimates actual caloric consumption. For example, Schoeller (1995) highlights limitations in self-reported dietary energy intake assessments, leading to discrepancies in nutritional data.
Accurate food databases can reduce these discrepancies. Hill and Davies (2001) found that validated entries improve dietary assessments. Nutrola's commitment to 100% RD verification ensures that users receive reliable nutritional information.
