Report a data issue

If you spot an incorrect nutrient value, a missing food, or any other data problem, please email us with the subject "Data issue" and include the food or nutrient name and what you believe is incorrect. All nutrient data comes from the USDA FoodData Central database — for issues that originate there we'll link you to the USDA feedback form.

General feedback

Suggestions for new features, missing foods, or anything else — we're happy to hear it. We can't guarantee a reply to every message but we read everything.
