Methods and sources

This page says where the numbers on this site come from and what we don’t claim. The app’s About us screen leads here.

Where the example week’s nutrition comes from

The example week shown on this site (calories, protein, carbs, fat, sodium, saturated fat and the other values in the day deep-dive) is computed from each recipe’s ingredient weights. Nutrient estimates are based on USDA FoodData Central. Our tables are hand-compiled from it, so treat every value as an estimate, not a lab measurement. A few ingredients (such as Mexican crema or gyoza wrappers) don’t have an exact FoodData Central match; we used the closest entry and noted it internally.

Daily Values

The percentages and targets shown against the example week (for example, the 2,100 kcal goal, 2,300 mg sodium and 20 g saturated fat lines) are the FDA’s Daily Values for a 2,000-calorie diet, the same reference values printed on US nutrition labels. They describe a general reference diet, not a target personalized to any one person.

Where experts disagree

The World Health Organization recommends less sodium, and a lower ideal for sugar, than the US Daily Value used on this site. WHO guidance is to keep salt under 5 g a day (about 2 g of sodium), which is stricter than the FDA’s 2,300 mg sodium Daily Value (about 5.8 g of salt). On sugar, WHO advises free sugars under 10% of daily calories, about the same as the FDA’s 50 g added-sugar Daily Value (10% of a 2,000-calorie diet), and says going below 5% brings extra benefit. We show the FDA figures because they match the label reference US shoppers already see; we note the difference here rather than pick a side.

Allergies

Nutrinity filters recipes and products by your allergies, but labels and recipes can change and stores can substitute. Always read the label before you eat. If you have a severe allergy, talk to your doctor.

Two specifics: “dairy” means cow’s milk and other animal dairy, so plant milks are fine even when you’ve listed a dairy allergy; and a product labeled gluten-free is allowed when you’ve listed a gluten allergy.

Who this is for, and what we don’t claim

Nutrinity is built for healthy people. It is not designed for pregnancy, breastfeeding, kidney disease, diabetes management or eating disorders, and anyone in those groups should talk to a clinician before using its numbers. If you are under 18, use Nutrinity only with the permission of a parent or legal guardian, and talk to a doctor or registered dietitian about how much you should eat while you are growing. Nutrinity does not set weight-loss calorie deficits for people under 18.

Nutrinity is not a medical device and does not diagnose or treat any condition. Plans come from an AI model; every number is an estimate, not medical advice. We cite published sources and guidelines by name; none of the organizations named on this page has reviewed or endorsed Nutrinity.
