Free, comprehensive nutrition data powered by USDA FoodData Central — accessible to everyone, with no paywalls and no signups.
Food is the foundation of health — yet most people have no idea what they are actually eating. We built Nutosa because we believe that understanding your food should not require a degree in nutrition science. Our mission is simple: provide free, accurate, and comprehensive nutrition information to everyone, so that every person — regardless of background, budget, or expertise — can make informed decisions about what they eat.
Too many nutrition websites hide useful data behind paywalls or bury it in confusing interfaces. We take the opposite approach. Nutosa gives you instant access to detailed nutrition facts for nearly 500,000 foods, completely free, with no account required for basic lookups. We want you to know the difference between what nourishes your body and what harms it. Which foods are packed with vitamins and minerals, and which are loaded with sugar, sodium, or empty calories. Whether the "healthy" label on a package actually means anything — or if you are better off reaching for something else.
We started Nutosa in 2026 with a clear goal: become the most accessible and trustworthy nutrition database on the internet. Every feature we build, every piece of data we present, and every design decision we make is guided by that principle. Nutrition knowledge should empower people, not confuse them — and that is what we work toward every single day.
All nutritional information on Nutosa is sourced from the USDA FoodData Central database, maintained by the United States Department of Agriculture. This is the gold standard in food composition data and the same source used by researchers, dietitians, and health professionals worldwide.
We incorporate data from two primary USDA datasets. The SR Legacy (Standard Reference) database contains research-grade nutrient profiles for thousands of common foods — fruits, vegetables, meats, grains, dairy, and more. Each entry in the SR Legacy dataset has been analyzed in laboratory settings, with nutrient values measured through standardized scientific methods including chromatography, spectrophotometry, and combustion analysis. The Branded Food Products Database extends our coverage to include packaged and branded foods, with nutrition label data contributed by food manufacturers through the USDA Global Branded Food Products Database (GFBPD) program.
Together, these datasets give Nutosa users access to nutrition facts for nearly 500,000 food items. We regularly sync our database with the latest USDA releases to ensure accuracy. Each food entry includes up to 65 individual nutrient values, covering macronutrients (calories, protein, carbohydrates, fat, fiber), vitamins (A, C, D, E, K, B-complex), minerals (calcium, iron, magnesium, potassium, zinc), and other components like cholesterol, saturated fat, and added sugars.
Daily Value percentages shown on Nutosa are based on the FDA reference diet of 2,000 calories per day, following the most current Daily Reference Values (DRVs) and Reference Daily Intakes (RDIs) established by the U.S. Food and Drug Administration. For more details, see our Data Sources page.
Detailed nutrition facts for nearly 500,000 foods, including macros, vitamins, minerals, amino acids, and fatty acids. Every food page shows a full nutrient breakdown per 100g and per serving, with Daily Value percentages based on FDA guidelines.
Our AI meal planner creates personalized 7-day or 30-day meal plans based on your body stats, dietary preferences, and weight goals. Each plan includes precise calorie targets and balanced macronutrient ratios tailored to your needs.
Compare any two foods side by side to see which one better fits your diet. Our comparison tool highlights differences in calories, protein, carbs, fat, vitamins, and minerals — making it easy to choose the healthier option.
Upload a photo and select a weight goal to see a realistic AI-generated preview of your future self. This feature provides instant visual motivation to help you stay committed to your health and fitness journey.
Discover which foods rank highest for any nutrient — protein, fiber, iron, vitamin C, potassium, and more. Our ranking pages show the top 50 foods per nutrient, helping you find nutrient-dense options quickly.
Browse 400+ food categories from fruits and vegetables to snacks and beverages. Each category page lists all foods with sortable nutrition columns so you can find exactly what you need.
People rely on our numbers to make real health decisions — from managing diabetes to planning meals for their families. We take that responsibility seriously.
All nutrition values on Nutosa are sourced directly from the USDA FoodData Central database. We do not estimate, interpolate, or generate nutrient values ourselves. When the USDA publishes updated data, we update our database accordingly. Our data processing pipeline includes automated validation checks that flag any anomalies — such as unusually high or low values — for manual review before they appear on the site.
We also maintain a process for user-reported corrections. If you notice any data that appears incorrect, you can contact us and our team will investigate. We cross-reference reported issues against the original USDA data and, when confirmed, apply corrections promptly.
All content published on Nutosa — including guides, articles, and food descriptions — follows a rigorous editorial process. Our content is researched against peer-reviewed scientific literature and authoritative government sources, primarily the USDA and the U.S. Food and Drug Administration (FDA).
We do not publish unverified health claims. Nutritional recommendations on our site align with guidelines from the Dietary Guidelines for Americans and other recognized health authorities. Every piece of content goes through a fact-checking review before publication to ensure accuracy and clarity.
For a detailed overview of our content creation process, fact-checking methodology, and correction policy, please see our full Editorial Policy page.
