Frequently asked questions
Where do these nutrition figures come from?
They come from USDA FoodData Central, a public-domain dataset published by the U.S. Department of Agriculture. Each food page credits the specific dataset and release it was taken from.
Why do some nutrients show “Not reported”?
Because the source dataset does not contain a value for that nutrient in that food. A blank means “not measured”, which is different from zero. We never display a missing value as 0, because that would assert something the source does not say.
Can I rely on this for an allergy?
No. Allergen information in reference datasets is incomplete and is not a substitute for reading the actual product label. Always check the label on the product you are going to eat.
Why does a branded product differ from the generic version?
Because composition genuinely differs. Reference values describe a typical sample; a specific brand’s formulation, and its preparation, will vary. Where a branded record exists we show it separately from the generic reference.
Is this dietary or medical advice?
No. This site reports published composition data and does not give dietary or medical advice. For your own diet or a medical condition, consult a qualified professional.
How often is the data updated?
We refresh from the published USDA releases on a schedule. The date of the release used is shown on the page and in our data coverage report.
