How to compare protein sources by price per serving
The simplest way to compare low-cost protein sources in the UK is to work out the cost per serving, not just the shelf price. A large bag may look expensive, but if it gives you many portions, it can be much cheaper overall.
Start by checking the protein content on the label. Then divide the pack price by the number of servings you will actually eat, or by the number of protein grams if you want a more precise comparison.
What counts as a serving
A serving should match how you normally use the food. For example, 30g of oats, 2 eggs, or half a tin of beans may be a realistic portion, while a full pack or full tin may not be.
This matters because some foods are very cheap per pack but low in protein per portion. Others cost a little more upfront but give a much better protein hit for the money.
Common low-cost UK protein options
In the UK, some of the best-value protein foods include eggs, tinned beans, lentils, chickpeas, Greek-style yogurt, cottage cheese, peanut butter, and frozen chicken thighs. Tinned tuna and sardines can also be cost-effective when bought on offer.
Dry pulses and lentils are often among the cheapest choices because they bulk up when cooked. Dairy products can be good value too, especially supermarket own-brand versions.
How to compare prices properly
Look at the unit price as well as the pack price. Supermarkets usually show this per 100g, per kilogram, or per item, which makes comparison easier across different pack sizes.
For a more useful comparison, calculate price per serving yourself. For example, if a 1kg bag of lentils costs £1.80 and gives around 10 cooked servings, that is about 18p per serving before adding other ingredients.
Don’t forget protein quality and satiety
Price matters, but so does how filling the food is. Some cheaper proteins need combining with other foods to make a full meal, such as beans with rice or lentils in a curry.
Animal proteins often have more protein per serving, but plant proteins can still be excellent value. If you eat a varied diet, mixing both can help keep costs down while supporting your nutrition needs.
Quick tips for saving money
Buy own-brand versions, check multi-buy deals carefully, and compare frozen, tinned, and dried options. Dried lentils and beans are usually the cheapest, while frozen chicken and tinned fish can be strong-value picks when discounted.
Planning meals around one main protein source helps reduce waste. If you cook in batches and freeze portions, you can make low-cost protein go much further each week.
