What is a calorie checker, and how does this one work?
A calorie checker (sometimes called a calorie database or calorie searcher) is a tool that looks up how much energy — measured in kilocalories (kcal), usually just called "calories" — a food provides per 100 grams or per typical serving. Rather than relying on packaging labels, which can vary between brands and countries, 247CalorieCheck draws every figure directly from the USDA FoodData Central database — the United States Department of Agriculture's official food composition reference, used by nutrition professionals and researchers worldwide.
Type any food into the search box above and you will land on a dedicated page showing its calories, protein, carbohydrates, fat, fibre, and a full micronutrient breakdown per 100g — plus a live serving calculator so you can convert the figures to whatever portion you actually eat. There is no login, no app to download, and no paywall.
Why use a food calorie database instead of guessing?
Portion size is the single biggest source of error when people track calories by memory or by eye — a "handful" of nuts or a "splash" of oil can vary by hundreds of calories from one person's estimate to another's. Looking up the real per-100g figure and weighing your actual portion removes that guesswork entirely. This is also why every food page on this site includes a serving-size calculator: type in the exact weight of what you are eating and every nutrient recalculates instantly, rather than forcing you to do the maths yourself.

Frequently Asked Questions
What is a calorie checker?
A calorie checker is a tool that tells you how many calories a food contains, usually per 100g or per typical serving. 247CalorieCheck is a free calorie database covering thousands of foods, all sourced from USDA FoodData Central rather than estimated.
How accurate are online calorie counters?
Accuracy depends entirely on the data source. Figures here come directly from USDA FoodData Central, the official US government food composition database — the same source used by dietitians and researchers. Real foods vary slightly by ripeness, brand and preparation, so treat any figure as a close reference value rather than an exact measurement of the specific item in front of you.
How many calories should I eat a day?
This varies by age, sex, activity level and goals, so there is no single correct number — a commonly cited reference point is around 2,000 calories a day for an average adult, which is the figure UK and US food labelling uses for percentage calculations. For personal guidance tailored to you, a registered dietitian is the right person to ask.
Is this calorie database free to use?
Yes. There is no login, no account, no app to download, and no paywall. Every food page and the search tool above are free to use as often as you like.
Where does your nutrition data come from?
Every figure on this site is sourced from USDA FoodData Central, the U.S. Department of Agriculture's official food composition database, released under a CC0 1.0 public domain licence. We do not estimate or generate nutrition figures — every number traces back to that dataset.
