Jot down a few questions to make the most of your conversation.
Check the protein per pound
When choosing low-cost protein sources in UK supermarkets, the first thing to compare is the protein content per 100g or per portion. A cheap-looking product is not always the best value if it only contains a small amount of protein.
Look at the price alongside the nutrition label, and think in terms of cost per serving. Items like eggs, dried lentils, beans, tinned fish, and natural yoghurt often give good protein for the money.
Compare fresh, frozen and tinned options
Frozen and tinned foods can be excellent budget choices. They often last longer than fresh products, which means less waste and better value over time.
Frozen chicken, frozen fish, tinned tuna, tinned sardines, and tinned beans are all worth checking. These options can be easier to store in small kitchens and are often on offer in major supermarkets.
Watch out for added extras
Some protein foods become more expensive because of added sauces, coatings or seasoning. Breaded chicken, flavoured yoghurt, and ready-made protein meals can cost more per gram of protein.
Plain versions are usually cheaper and more versatile. You can add your own herbs, spices, or sauces at home and keep the overall cost lower.
Consider vegetarian and plant-based proteins
Plant-based protein sources are often among the cheapest in UK supermarkets. Lentils, chickpeas, kidney beans, tofu, peanut butter, and oats can all help you build affordable meals.
These foods are also useful because they can stretch across several meals. For example, one bag of dried lentils can make soups, curries, bolognese, and salads.
Look for value pack sizes and own-brand labels
Supermarket own-brand products are often better value than branded versions. This is especially true for basics such as eggs, yoghurt, beans, milk, and cheese.
Larger pack sizes can save money, but only if you will use them before they go off. It is worth checking the unit price on the shelf label rather than just the headline price.
Think about nutrition, not just cost
Low-cost protein should still fit your wider diet. Some cheaper options may be high in salt, sugar, or saturated fat, so check labels if you are buying processed foods.
A mix of protein sources is usually best. Combining beans, grains, dairy, eggs, fish, and meat where budget allows can help you eat well without overspending.
