About YummyMetrics
What is YummyMetrics?
YummyMetrics is a free nutrition website for ingredients. It shows calories, protein, carbohydrates, fat, fiber, sugars, sodium, vitamins and minerals for thousands of foods, and offers tools such as a recipe nutrition calculator and side-by-side food comparisons.
Is YummyMetrics free? Do I need an account?
Yes, it's completely free and there's no sign-up. The site is supported by advertising.
Who runs YummyMetrics?
YummyMetrics is operated by Vyziotek, based in Dubai, United Arab Emirates. You can read more on our About page.
Will YummyMetrics be available in other languages?
Yes. YummyMetrics is available in English, Spanish (español) and French (français), with local food names and familiar units rather than direct translations of English labels.
Our data
Where does the nutrition data come from?
From USDA FoodData Central, the public food composition database of the U.S. Department of Agriculture. We use its Foundation Foods and SR Legacy datasets. Details are on our Data & Methodology page.
How accurate are the numbers?
The values are laboratory-based averages for representative food samples, so they're a reliable reference. Any single food can still differ because of variety, ripeness, growing conditions, processing and cooking. Treat them as good estimates, and check the label on packaged products when precision matters.
Why doesn't a food match the label on my package?
Our data describes generic ingredients, not specific brands. Manufacturers' recipes, added salt or sugar, and the rounding rules used on nutrition labels all cause differences. For a packaged product, the label on that product is the best source.
Why are there separate raw and cooked entries?
Cooking changes weight. Dry pasta and rice absorb water, while meat loses water and fat. So 100 g of cooked rice contains far fewer calories than 100 g of dry rice. Pick the form that matches what you weigh: if you weigh the food before cooking, use the raw or dry entry.
A nutrient shows “—”. Does that mean zero?
No. A dash means the USDA doesn't report a value for that nutrient in that food. It may be present; it just wasn't measured.
Does the USDA endorse YummyMetrics?
No. We use the USDA's public data and credit it on every page, but the USDA does not endorse YummyMetrics or anything shown on it.
Reading the numbers
What does “per 100 g” mean?
It's the amount of each nutrient in 100 grams of the edible part of the food — without peel, pits, bones or shells. Using the same weight for every food makes them easy to compare. To get the value for your portion, multiply by your weight in grams and divide by 100. For example, 150 g of a food with 164 kcal per 100 g has 164 × 150 ÷ 100 = 246 kcal.
What does “per 100 kcal” mean, and why is it useful?
It shows how much of each nutrient you get for every 100 calories of a food. It's the fairest way to compare nutrient density. For example, boiled lentils give about 7.8 g of protein per 100 kcal, while boiled chickpeas give about 5.4 g.
Why do protein, carbs and fat not add up exactly to the calories?
The quick rule of 4 kcal per gram of protein or carbohydrate and 9 kcal per gram of fat is an approximation. The USDA calculates energy with more precise factors that differ by food, and fiber provides fewer calories than other carbohydrates. Small gaps are normal.
Do carbohydrate values include fiber?
Yes. We show total carbohydrate as reported by the USDA, which includes fiber. If you track net carbs, subtract the fiber value.
How does the recipe calculator work out a recipe?
It converts each ingredient to grams, multiplies by that food's per-100 g values, adds everything up and divides by the number of servings. See our real-world example for the full calculation, step by step.
