Why is the USDA FoodData Central trusted for composition data?
Answer
The data often originates from direct laboratory analyses or validated references.
The United States Department of Agriculture (USDA) FoodData Central is considered a high degree of trust source because its data is frequently derived directly from laboratory testing performed on food samples or validated, established references. This direct sourcing provides a higher level of confidence in the accuracy compared to data compiled solely through less rigorous means. While many online tools pull data from such repositories, the fundamental reliability of FoodData Central stems from its reliance on empirical, tested values, making it a benchmark for nutritional information.
