Nutrition data sources

Last updated: September 14, 2026

MinMax shows calories, protein, carbohydrates, fat, fiber, and sodium for 29 U.S. fast-food chains. For 20 chains the values come from nutrition information the chain publishes itself. For the other 9 chains they come from a third-party table, and the app labels those chains Third-party.

Under every order in the app, a source line names where its numbers came from. Tap it to open Source & freshness: the source, with a link to the page or document, its tier (Official or Third-party), the date of the values, when MinMax last checked them, and any nutrient the chain does not publish. The same sheet opens from Nutrition source in an order's menu, and menu → About & privacy → Nutrition sources lists every chain with its tier.

How the data is collected

Official: we read the chain's own nutrition guide, PDF, or the nutrition data on its own website — typically published to satisfy U.S. menu labeling rules (FDA Menu Labeling Final Rule, 21 CFR 101.11).
Third-party: when we can't yet read a chain's own figures reliably (for example, because they are published only in an interactive calculator or as an image), we use the chain's page on healthyfastfood.org, a third-party site that compiles chains' published nutrition figures. The app says so on every order from these chains.
Values are extracted automatically and kept as the source publishes them. We do not adjust or round them, and we do not estimate missing values: if a chain does not publish a nutrient, the app shows it as not published.
For build-your-own items, such as a Chipotle bowl or a Five Guys burger, the totals are the sum of the chain's published values for each part.
Automated checks drop rows whose numbers contradict each other (for example, protein, carbohydrates and fat that don't add up to the calories), and a chain appears in the app only when enough of its menu passes.
The app carries its menu data inside it; menu → About & privacy → Dataset shows its version and build date. New data arrives with app updates. The website is refreshed on its own schedule, so its numbers can be newer than the app's.

Chains and their sources

Each chain also has a page on MinMax (eatminmax.com) with its full menu, sorted by calories and protein, and a link to its source.

Official: the chain's own nutrition information (20)

Third-party: healthyfastfood.org (9)

Values are the national U.S. figures the source publishes and can vary by location; check allergens with the restaurant. Not affiliated with or endorsed by any restaurant.

Important limitations

Nutrition information can vary by location, by individual order, and over time. The values displayed represent the restaurant's published standard preparation and may differ from a specific order you receive. Variations from the published values are common for:

Modifications you request (extra sauce, no cheese, etc.)
Regional menu differences between U.S. locations
Menu changes made after the date shown in the app
Natural variation between individual orders prepared by hand

If you have specific medical or dietary requirements

MinMax is a meal-finding tool. It is not a medical, dietary, or nutritional service and should not be used as a substitute for professional guidance. If you have diabetes, food allergies, a managed dietary restriction, or any other medical condition that depends on accurate nutrition values, please verify the values directly with the restaurant before ordering. The source line under every order links to the page or document its numbers came from; for chains labelled Third-party, check the chain's own information too.

Reporting an error

If you believe a value shown in MinMax is incorrect — for example, it doesn't match what the restaurant currently publishes — open the order and tap Report a problem, or email support@eatminmax.com with the restaurant, item name, and the value you believe is wrong. We re-check the source and correct the data in a later update.
