Nutrition calculator
Search any food to get its nutritional value — calories, protein, carbs, fat, and the full vitamin and mineral breakdown, straight from USDA FoodData Central.
Common questions
How many calories should I eat a day?
There's no single right number — it depends on your age, sex, height, weight, and activity level. A sedentary 140 lb woman and an active 200 lb man have very different needs. For a number based on your own stats, use the TDEE calculator, which estimates your maintenance calories and lets you adjust from there for weight loss or gain.
How do I track my calories?
Search each food you eat here to get its calories and macros, then add up the totals across your day. For a dish with several ingredients — a stir-fry, a sandwich, a smoothie — the recipe nutrition calculator combines them into one per-serving total instead of adding each ingredient by hand.
What's the difference between this and the recipe nutrition calculator?
This tool looks up one food at a time — search "banana," get banana's nutrition facts. The recipe calculator combines multiple ingredients into a single dish's totals, which is what you want when you're cooking something with several components.
Where does this nutrition data come from?
USDA FoodData Central — the U.S. government's public nutrition database, covering raw ingredients and many prepared dishes. It's the same source used throughout NutriFactsHub.
How accurate are the results?
For raw ingredients and generic foods, USDA's data comes from laboratory analysis, not estimates — among the most reliable nutrition data publicly available. For a specific restaurant chain's exact menu item, a generic search here won't return that chain's own formulation; check the fast food section instead, where figures are verified against each chain's own published numbers.
What's the difference between calories and macros?
Calories measure total energy. Macros — protein, carbs, and fat — are the three nutrients that make up those calories, each contributing a different amount per gram (protein and carbs: 4 calories per gram; fat: 9). Two foods can have the same calories but very different macro splits. If you're tracking toward specific protein, carb, and fat targets rather than just a calorie total, the macro calculator gives you those targets directly.
Looking for something more specific?
This tool looks up one food. For a daily target built around your own numbers, or for combining several ingredients into one dish, one of these is a better fit.
