Eating a healthy and balanced diet can sometimes seem like a costly expense – particularly if you have to grab food on-the-go.
Cambridge University reported that healthy foods can cost three times as much as unhealthy foods. The study found that 1,000 calories made up from healthy items, such as salmon, yoghurts and tomatoes, cost an average of £7.49; whereas the same calorie intake from fewer healthy items, such as pizza, beef burgers, and donuts, could be purchased for an average of £2.50.
Even if you’re on a budget, you can still eat nutritious meals. With a bit of research and comparison shopping, you can discover plenty of affordable and healthy protein options. By keeping a list of these go-to sources, you’ll make sure you’re getting the essential nutrients your body needs, especially if you’re active and need a protein-rich diet for your fitness goals.

We’ve price checked these foods across UK supermarkets, stating the protein content and cost by weight – so you can see exactly how much protein you’re getting for your pennies!
Here’s our ultimate top 15 low-cost, high-quality protein sources that suit every dietary need, so get your shopping list ready…
Fish is a fantastic source of protein and omega 3 fatty acids, however fresh fish can sometimes be on the pricey side. This is where tinned tuna (or other tinned fish such as salmon/mackerel) is hard to beat in terms of cost and protein content! Low in fat and calories, this store cupboard staple can be a great fail-safe food when eating on a budget. A good one to buy in bulk when it’s on offer too due to its long shelf life.
Use to make fillings for jacket potatoes or sandwiches/wraps/pittas. Tuna also works great mixed with an egg and breadcrumbs to make tasty tuna meatballs or burger patties! Experiment with this store cupboard staple and see what creations you can make – every kitchen cupboard should have at least one tin of tuna in stock!
Most supermarkets offer packs of 4 tins of tuna, these work out at:
= less than 50 pence per 100g tuna.
Approx. 24g protein per 100g of tuna
Tip – Tinned salmon, mackerel and sardines are also very cost effective and good quality sources of protein and omega 3 fatty acids.
Eggs have suffered a few knocks to their reputation over the years, however, eggs are in fact one of the most nutrient-dense, affordable foods in the world! While the whites of eggs are packed with protein, those golden yolks are bursting with vitamins, minerals, antioxidants and fatty acids (only free range) so you get even more nutrients for your money!
Even on a tight budget, there is no need to opt for caged hens eggs today as all supermarkets offer own-brand affordable free-range eggs. It really is worth the extra few pence you pay for free range as caged hens eggs don’t have the same nutrients as free range!
Use your eggs to make a delicious Breakfast Omelette which will keep you sustained throughout the morning and fuller for longer, helping you save even more money!
Cost per half dozen free range eggs = as little as 80p in ‘big-4’ supermarket
= Works out at less than 14 pence per egg
Approx. 6g protein in one egg.
Natural peanut butter is an incredible source of healthy fats and protein. Not just for spreading on toast; peanut butter can be a wonderfully versatile cooking ingredient used in baking, marinades (for meat/fish/tofu), dressings and sauces, eaten with fruit such as apples and bananas or spooned into your oats, smoothies or protein shakes for an added hit of nutrients!
Opt for a good quality natural peanut butter like our Only Peanuts rather than a generic supermarket own-brand or value peanut butter as these will likely be filled with added salt, sugar, fat and possibly palm oil/additives etc. As the same suggests, our Only Peanuts contains nothing but 100% peanuts, so you end up getting more peanut for your money, rather than additives and unnecessary sugar!
Protein Works Only Peanuts £8.99 per 990g
= Less than 28p per 30g serving.
Approx. 8g protein per 30g serving.
Next on our list of cheap protein sources are frozen soya beans! These luminous little green beans are not only delicious, but a great source of plant-based protein!

Unlike many other plant proteins, soya beans are a complete protein as they contain all of the essential amino acids for human nutrition.
= works out at 45p per 100g serving (frozen weight)
Approx. 14g protein per 100g serving (frozen weight)
Greek yogurt has twice as much protein as regular yogurt and is a good source of casein protein. However, protein and fat content can vary quite significantly from brand to brand, so check the label to see how it stacks up. Where possible, always opt for plain unsweetened Greek yogurt rather than flavoured varieties as these are generally full of added sugar.
Use in smoothies and shakes, mix into oats or use to make tasty marinades for meat/fish, dips and dressings! Blend with your favourite fruit or flavoured protein powder and freeze to make delicious, high protein fro-yo – yum! Some recipe inspiration includes this colourful Protein Berry Yogurt recipe, perfect for a snack all day long.

= 18p per 100g serving
Approx. 8g protein per 100g
Undoubtedly one of the most popular foods on the list (particularly amongst fitness fanatics), chicken is a great source of complete protein but depending on the cut of meat, can be expensive. Breast meat is the lowest source of ft of any part of a chicken, but is also the priciest! Cheaper cuts include the fillets (often referred to as ‘mini fillets’) which are the little fillets located under the breast meat. These are similarly low in fat as breast meat but considerably less expensive!
Many supermarkets also offer this cut of meat frozen which works out even cheaper still. Other cheap cuts of chicken include thighs, while these may be significantly higher in fat, this is namely due to the skin. So, providing you remove the skin you will have cut a huge proportion of the fat content and calories.
Whole chickens can also work out to be very cost effective and can be used for more than one meal. A whole chicken is approximately 58% meat, which means that a large chicken weighing 1.6kg would give you just under a kg of meat, containing more than 250g protein! Whole chickens are frequently on offer in supermarkets so keep your eyes peeled!
Supermarket own-brand chicken ‘mini’ fillets:
= 55p per 100g serving
Approx. 28g protein per 100g serving
Most supermarkets sell large bags of own-brand or branded dried chickpeas, which work out even cheaper than the tinned variety! If you don’t have the time or inclination to soak/cook dried chickpeas – tinned chickpeas are still a super-cheap quality source of protein!
Chickpeas are well worth having stocked up as you can easily whip up a batch of hummus in minutes or use to make our unreal high-protein falafel burgers! Toss them in a little olive oil and spices, roast in the oven and you have a delicious savoury snack that’s packed full of protein and fibre! Perfect in soups and stews with a universally pleasant and mild flavour, chickpeas are a low-budget no-brainer!
= less than 15p per 100g dried weight

Approx. 18g protein per 120g drained chickpeas
Tofu is a complete protein source, so is a great option for vegetarians/vegans, it is also a good source of calcium and iron. A bit of a ‘love it or hate it’ type food, don’t let previous bad tofu experiences put you off! Drain as much water as possible out of the tofu and press before cooking to avoid an unpleasant texture.
Tofu is very bland on its own but is great at carrying strong flavours, so marinade in something punchy and flavourful for at least 2-3 hours (overnight if possible) before cooking to get maximum flavour from this plant-based protein source. You can use tofu in recipes for curries, stews, stir fry dishes, and wraps to name a few!
396g pack branded tofu from supermarket:
= less than 40p per 100g serving
Approx. 12g protein per 100g serving
Turkey mince is an inexpensive source of complete protein and works a treat in many different recipes. Although, it can sometimes be fattier than you may expect with poultry, so check the fat content – a lot of supermarkets offer both a lower fat (around 2-3%) and higher fat (around 7-8%) variety. it’s a great substitute for minced beef in cooking and makes fantastic meatballs!

Cheese is the highest concentrated source of dairy protein, however this usually comes along with a heavy fat content…Step forward cottage cheese! Giving you the best of both worlds in terms of its high-protein and calcium content, whilst being low-fat/calorie (providing you go for a low-fat/fat-free variety). It can sometimes be high in salt, so check the label!
Cottage cheese is another surprisingly versatile protein source in sweet and savoury recipes; use it as you would with yogurt to boost protein in your overnight oats or bulk out your protein pancake mix.

Protein powders are arguably the most convenient and cost-effective method of hitting your protein goals.

Whey protein is a by-product of cheese manufacturing and is one of the most concentrated sources of complete protein available.

For those following a plant-based diet, look no further than our Vegan Protein! For many years people have argued about whether plant-based protein powders are as good as whey protein powders and the reality is, as long as the vegan protein powder is made from a variety of different high, quality protein sources then it is entirely comparable to a whey protein.
Our Vegan Protein is made from a premium blend of soy, pea, pumpkin seed, sunflower and brown rice protein to ensure a deliciously creamy shake packed with 25g protein per 30g, costing less than 50p per serving!
= Less than 50p per 30g serving

These little legumes are another rich source of plant-based protein. Lentils are regularly used to substitute meat in many vegetarian/vegan dishes such as shepherds pie or curries. However as it is plant-based, it isn’t a complete source of protein on it’s own so should be combined with other protein sources such as wild rice, whole wheat bread or quinoa to get all the essential amino acids your body needs.

Tinned green lentils are also generally cheap and as they are pre-cooked, can be thrown straight into a salad or soup for an extra boost of protein!

A daily staple in many western diets, cow’s milk is an excellent and affordable source of complete protein. Milk is comparable with eggs in terms of affordability and protein content. If you are watching your calorie or fat intake, opt for skimmed milk which is 1% fat but still retains the same protein content. Some studies have shown that organic milk has higher levels of nutrients so if its within your budget, opt for organic to get maximum benefits.
