Free Nutrition Data & Calorie Information for 300,000+ Foods

CalorieData was built to solve a simple but important problem: finding accurate, comprehensive nutrition information should be easy and free. Too many nutrition databases are locked behind subscriptions, cluttered with ads, or rely on unverified user-submitted data. We took a different approach by building our entire platform on the USDA FoodData Central database, the gold standard for food composition data in the United States. Every calorie count, macro breakdown, and micronutrient value you see on CalorieData has been verified through laboratory analysis conducted under USDA oversight.

Our database covers over 300,000 foods, ranging from basic whole foods like chicken breast, brown rice, and broccoli to branded products, restaurant items, and specialty ingredients. Each food page provides a complete nutritional profile including calories, protein, carbohydrates, total fat, saturated fat, fiber, sugar, sodium, and key vitamins and minerals. We display values per standard serving size and per 100 grams, making it easy to compare foods regardless of portion size differences.

Beyond raw data, we provide context that helps you actually use the information. Our food comparison tool lets you place any two foods side by side to see which is higher in protein, lower in calories, or better for a specific dietary goal. Our calculators help you determine personalized calorie and macro targets based on your body composition, activity level, and goals. And our curated food lists organize the database by nutrition profile, so you can quickly find high-protein foods, low-calorie options, iron-rich choices, or foods high in specific vitamins.

Nutrition science continues to advance, and 2026 has brought several notable shifts in how people approach dietary planning. Protein awareness has reached an all-time high, driven by growing recognition that adequate protein intake supports not just muscle building but also satiety, metabolic health, and healthy aging. Our high-protein food lists and protein-per-calorie rankings have become some of our most visited pages as more people prioritize this essential macronutrient regardless of whether they follow a specific diet plan.

The conversation around ultra-processed foods has also intensified, with emerging research linking highly processed diets to a range of health outcomes. More consumers are using nutrition databases like CalorieData to compare whole food options against processed alternatives, not just by calorie count but by looking at fiber content, added sugars, sodium levels, and overall nutrient density. Our food comparison tool is particularly useful for this purpose, allowing you to see at a glance whether a convenience food is nutritionally comparable to its whole food counterpart.

Meal prep has also continued to grow as both a health strategy and a budget-conscious approach to eating well. Our meal prep guides help readers plan balanced meals that meet their caloric and macro targets while minimizing food waste and kitchen time. Whether you are prepping high-protein lunches for the work week, building low-calorie dinners for weight loss, or assembling family-friendly meals that satisfy everyone at the table, our guides combine nutritional data with practical cooking advice to make healthy eating sustainable over the long term.
