Check calories and key nutrition for everyday foods or branded products. Search by name, choose the exact match, or scan a barcode with your phone.
Find a food
What would you like to check?
Search for an everyday food such as banana or a branded product such as Kellogg's Corn Flakes. We show choices rather than guessing which food you mean.
Search happens only when you press Search foods — nothing is sent as you type.

How the checker chooses its data
01
Everyday foods
Generic foods use the UK Composition of Foods Integrated Dataset (CoFID), so a search for chicken, rice or fruit is grounded in UK reference data.
02
Branded products
Packaged products use Open Food Facts. We keep these results visibly separate because product data can be incomplete or change after reformulation.
03
Your portion
The selected food provides a per-100g or per-100ml baseline. The checker scales those values to the amount you choose.

Keep the bigger picture together
Use the calculator that matches what you want to understand next.
A PrimeLife clinician can assess your health history and suitability. Using this public checker does not create a clinical record or determine treatment eligibility.
Important: Nutrition values are for general information. Generic food values are typical reference values and branded product records may be incomplete, outdated or entered by community contributors. Check the current product label when precise nutrition information is important. This tool does not provide medical or dietetic advice.

Food Calorie Checker: Check Calories and Nutrition
Knowing roughly how many calories are in a food can make meal planning easier. The PrimeLife Food & Calorie Checker lets you search everyday UK foods, look up branded products, adjust the portion size and check calories, protein and other key nutrition information.
You can search by food or product name, enter a barcode manually, or scan a product barcode with your phone. For everyday foods, the checker uses UK food-composition data. For branded products, it can show available product-label information.
How to calculate food calories
Food labels and nutrition databases usually give calories per 100g, per 100ml or per serving. To estimate the calories in the amount you actually eat, the serving size needs to be taken into account. The PrimeLife checker does this calculation for you: choose a suggested portion or enter your own weight or volume and the nutrition figures update automatically.
Calories are only part of the picture. The checker also highlights protein and shows carbohydrate, fat, saturates, sugars, fibre and salt where the source data are available.
Check everyday foods and branded products
A generic food and a branded product are not always nutritionally identical. A search for yoghurt, cereal or bread may therefore show several possible matches. Choose the item that most closely reflects what you are eating rather than relying on the first result.
For packaged food, check the current label when exact nutrition matters. Recipes, serving sizes and product formulations can change over time.
Why portion size matters
Calories shown per 100g can be difficult to translate into a normal meal. A portion of rice, a slice of bread and a banana are all easier to understand when the amount you plan to eat is included. Where possible, the checker offers practical portion choices as well as a custom grams or millilitres option.
Using calorie information for weight management
Calorie information can help you understand patterns in your diet, but it does not need to turn every meal into a maths exercise. Looking at overall intake, protein, fibre and the quality of your diet can be more useful than focusing on one food in isolation.
If you want to keep a record over time, you can add foods from the checker to the PrimeLife Food & Nutrition Diary and review your daily and weekly totals.
Looking for structured weight-management support?
PrimeLife combines practical weight-management tools with access to clinically led support where appropriate. Self-guided tools can help you understand your habits, but they do not replace an individual clinical assessment.
This article provides general information and does not replace medical advice. Always speak to your GP, pharmacist or another qualified healthcare professional before you start, stop or change any treatment. A qualified prescriber must assess whether a treatment is suitable for you. PrimeLife only prescribes treatment after a full clinical assessment.
