Does eating healthy have to be expensive? Not if you start with the food you already buy.

The weekly shop can be expensive enough before you add anything with a wellness promise attached. When you’re feeding a family, you want your money to go towards food everyone will eat and enjoy and that will help keep them well. But there is plenty of advice out there suggesting you should be adding something else to the trolley.

A greens powder to cover your nutritional needs. A protein bar or yoghurt to keep you going. A cereal with added fibre for your gut. It can leave you wondering whether your usual shopping basket is somehow falling short.

I can see why these products appeal. When something promises to help you look after your health, it is natural to be interested. The question is whether the benefit justifies the price, or whether you are paying extra for clever marketing.

Does eating healthy have to be expensive?

No, it doesn’t. Improving your diet can often start with the food you already buy, a clearer idea of what you need and a little planning so more of it gets eaten. None of those things add to the bill, and wasting less food takes money off it.

As a nutritional therapist, I want to help people make sense of the choices on the shelf. With food taking up so much of the household spend, it is worth knowing where your money makes a useful difference.

I’m currently making a conscious choice to reduce food waste at home and to plan out meals a little more.

Are greens powders and protein products worth the money?

For most people, no. The protein, fibre and greens on the label are already in ordinary food like eggs, beans, oats and frozen spinach. These products can be handy, but you don’t need them to eat well.

Health marketing is good at making an optional purchase feel like something you should have. Words such as “immunity”, “gut health” and “energy” catch our attention because they speak to things we care about. When you’re trying to look after yourself and your family, the promise of an extra benefit can be persuasive.

Greens powders, wellness shots, protein bars and “superfood” blends can gradually become part of the shopping routine. Each might seem like a fairly small purchase, but buying them regularly can add quite a bit to the bill.

Protein is the current favourite. The Irish Times recently asked why protein products are taking over supermarket shelves, and you’ll now find protein added to bread, yoghurt, puddings and even water. You can get the protein you need from ordinary food, and I’ve gone through how much you need and where to find it in Protein Hype vs Protein Truth.

With so much emphasis on these products, it is easy to get the impression that eating well has become expensive and complicated. You might be perfectly happy with your usual foods, then start wondering whether you should be buying something extra.

There may be a place for a product you enjoy or find handy. The difficulty is when it starts to feel essential simply because it is marketed as healthy. Looking after yourself and your family does not require buying every new product promising to help.

Granola is a good example of how a familiar food can become a premium purchase. Some beautifully packaged varieties come with a surprisingly high price tag. Making your own can work out considerably cheaper, especially when you use ingredients you already have.

When I costed my own recipe (link below), a batch came to about €5.60 and made roughly 750g of granola. That’s around €7.40 a kilo. A 400g bag of Flahavan’s Toasted Nut Granola in Tesco is €5, or €12.50 a kilo. So for a little more than the price of one bag, you get nearly twice as much. (Prices checked in Tesco, October 2026.)

You can choose the nuts and seeds you enjoy, adjust the sweetness and make a batch that suits your household.

I’ve been making versions of this granola recipe on and off for years.

Of course, buying ready-made granola may be what works for you. Homemade is an option, rather than another task to feel you should be doing. The useful question is whether you enjoy what you’re buying and feel it offers good value, or whether the packaging and health promises are doing most of the persuading.

I want people to feel comfortable making those choices. You can care about feeding yourself and your family well and still leave the expensive extras on the shelf.

Do you need supplements if you eat a healthy diet?

Not usually, unless there’s a specific reason for one. I do recommend supplements where they have a clear purpose. Correcting a deficiency, meeting a recognised need at a particular life stage or addressing a specific health concern following assessment are a long way from buying a product because its advertising sounds relevant.

An iron supplement recommended following assessment of low iron stores has a specific job. A collection of products promising energy, with no investigation into why someone is tired, may add expense while leaving the underlying problem unexplored.

When I recommend a supplement, I want to be clear that it is needed, that the evidence backs its use and that the dose is appropriate for what we are trying to achieve. I also consider the form it comes in and how well it is likely to be absorbed. Then we need a way to assess whether it is helping, when to review it and whether to adjust or stop it if it is not giving the expected benefit.

It is also worth reviewing what you already take. Several products may contain overlapping ingredients, and something that was useful six months ago may no longer be needed.

A clear recommendation should help you understand the reason for the purchase, rather than leave you accumulating bottles “just in case”.

What are the cheapest healthy foods?

Some of the cheapest healthy foods are the plainest ones in the supermarket: oats, eggs, tinned beans and lentils, tinned fish, frozen vegetables, natural yoghurt and whatever Irish vegetables are in season.

There is a lot of money to be made from convincing us that everyday food needs an upgrade. Add a “superfood” label, a promise about gut health or some impressive packaging, and suddenly the familiar option can seem a little inadequate.

I think ordinary food deserves more credit. Much of what keeps us well is already available in the supermarket, without a specialist label or a premium price. Familiar foods can provide protein, fibre, vitamins and minerals, even if their packaging has little to say about it. Oats, beans, lentils and wholegrain bread are good, inexpensive sources of fibre, and I’ve written more about them in Your Gut Isn’t Broken, It’s Underfed.

When I look at a client’s diet, I’m interested in what they eat regularly, where there might be gaps and which changes would make a useful difference. Often, there is plenty worth keeping. We can build on that rather than making the weekly shop more complicated or expensive.

Frozen and tinned foods deserve that same recognition. They can make a valuable contribution, and their longer shelf life allows us to use what we need without the pressure to finish everything within a few days.

The price difference can be bigger than you’d expect. In Tesco, a 900g bag of their own frozen leaf spinach costs €1.40, which works out at €1.56 a kilo. A 350g bag of fresh spinach is €1.99, or €5.69 a kilo. Fresh spinach also wilts down to almost nothing in the pan, so the frozen bag goes even further than those numbers suggest.

Berries tell the same story. Frozen raspberries come in at €6.67 a kilo, against €19.92 a kilo for a punnet of fresh ones, so you’re paying about a third of the price.

Understanding what your usual foods contribute makes it easier to recognise useful purchases, and to stop feeling that healthy eating requires a separate category of expensive ingredients.

How do you plan healthy meals on a budget?

Start with your diary and your fridge, then shop for the meals you’ll have time to cook that week.

There is the week we imagine when we are shopping, and then there is the week that happens.

In the imagined version, there is time to cook those new recipes. Everyone is home for dinner. The vegetables all get used. In the actual version, work runs late, someone needs a lift and the recipe requires more enthusiasm than you have left.

A useful plan takes those evenings into account.

Look at the diary before deciding what to buy. Which days allow time to cook? Which need something quick? Will everyone be eating at home? What is already in the fridge that needs using up?

A few reliable meals, some overlapping ingredients and an easy option in the freezer can give the week enough structure. Familiar dinners are useful; nobody needs seven new recipes every week.

If batch cooking would help on the busier evenings, my Kitchen Calm batch recipe ebook has simple meals you can make ahead and pull from the freezer. You’ll find it in my resource library, which is free to join.

Convenience can also earn its place. Prepared vegetables may cost more per kilo, but if they make cooking manageable and get eaten, that extra cost may be worthwhile. A useful meal plan needs to fit the time you have, your energy at the end of the day and what your family will eat.

I like a tray bake for busy evenings, you can throw anything in there and the clean-up is minimal.

Food waste costs the average Irish household €700 a year

The EPA estimates that food waste costs the average Irish household around €700 a year. Some of this will sound familiar. I know it certainly does to me! Leftovers forgotten at the back of the fridge, cheese that wasn’t wrapped properly and has gone off, meat that passed its use-by date before you got around to freezing it, bread that went stale, and fresh food bought for meals that never happened because plans changed.

The price at the checkout is only part of the story. A larger pack offers little saving if you throw away the extra. A special offer needs somewhere to go in your week.

Notice what your household regularly leaves behind. Buying a smaller quantity, choosing a frozen version or freezing part of a purchase early may suit you better.

Planning helps connect what we buy with what gets eaten. It also makes room for the occasional change of plan without leaving a fridge full of ingredients waiting for a dinner that never happens.

10 ways to eat healthy on a budget

Start with what’s already in the kitchen. Check the fridge, freezer and cupboards before writing your list. Look for ways to use what you find. You may already have the makings of a few meals.
Write your shopping list from your meal plan. Decide which dinners you’ll cook this week first, then list only what they need. The trolley follows the plan, rather than the other way round.
Eat the most perishable food first. Plan meals that use up fresh ingredients early in the week, and keep those ingredients at the front of the fridge where you’ll see them. Longer-lasting food can wait until later in the week.
Give ingredients more than one outing. Spinach could go into a pasta dish and an omelette; carrots into soup and a traybake. If a recipe needs half a tub or packet, think about where you’ll use the rest.
Have an easy dinner to fall back on. A pot of homemade soup with some good-quality wholegrain bread can make a simple, nourishing light evening meal. Including beans or lentils in the soup adds protein and fibre, making it more substantial. Freeze a few portions for evenings when you need dinner without much effort. My minestrone with beans and spinach is a good one to start with.
Keep a back-up shelf. A few tins of beans, chickpeas, tomatoes and fish, plus frozen veg and berries, mean there’s always the start of a meal in the house.
Give own-label products a fair try. A familiar brand is not automatically a better choice. Compare ingredients, nutrition information and price per kilo or litre. Tinned chickpeas are a good place to start. Tesco’s own organic chickpeas are 80c a tin, and Bunalun organic chickpeas are €1.45. Both tins hold 240g of chickpeas once drained, and both labels are chickpeas and water. Bunalun adds salt; Tesco adds ascorbic acid, which is vitamin C. The cheaper tin has no added salt. Try swapping a few things you buy regularly; keep the alternatives you enjoy.
Make special offers work for you. Before buying a larger pack or a multi-buy, ask whether you would have bought it anyway and whether you’ll use it all. Paying less per item offers little saving if the extra goes to waste.
Stretch meat with beans or lentils. Swap some of the mince in a bolognese or chilli for lentils or kidney beans. It costs less, adds fibre and the meal goes further.
Give leftovers a destination. Decide whether they are tomorrow’s lunch or a meal for the freezer, then store them promptly and safely. Label frozen portions with the contents and date so they are easy to find and use.

Nothing on that list needs you to buy anything new.

What working with a nutritional therapist looks like

People often tell me they expected to leave their first appointment with a list of superfoods and a bag of supplements. That isn’t how I work.

We start with what you already buy and cook, your health needs and what your week looks like. I want recommendations to make sense in your kitchen as well as on paper.

From there, we look for the changes that will make a difference for you. Usually that means using familiar food differently: a breakfast that keeps you going until lunch, protein at the meal where it’s missing, a plan so less gets thrown out.

If we do add something to your shopping list, you’ll know why it’s there, how we’ll tell if it’s working and when we’ll review it. The same goes for supplements you already take. Some of them will be doing a job. Others may have finished theirs a while ago.

There is a great deal we can do with familiar food, thoughtful adjustments and a clearer understanding of what is worth your money.

Frequently asked questions

Will working with a nutritional therapist make my food shopping more expensive?

It doesn’t have to. When I work with someone, we start with the food they already buy, their health needs and what their week looks like. Most changes involve using familiar food differently, like adding beans to a soup or planning so less gets thrown out. If I recommend a supplement or a specific product, there will be a clear reason for it and a plan for when to review it.

Is frozen veg as healthy as fresh?

Frozen vegetables are usually frozen soon after picking, which holds on to most of their vitamins. Studies comparing the two have found frozen veg broadly similar to fresh, and fresh veg loses some vitamins the longer it sits in the fridge. Frozen veg also lets you use exactly what you need and keep the rest. Choose plain frozen veg without added sauces or salt.

Are own-brand foods as healthy as branded ones?

Often, yes. Many own-label staples, like oats, tinned tomatoes, passata, frozen veg and natural yoghurt, have much the same ingredients as the branded versions. Check the ingredients list and the nutrition panel. Compare sugar, salt and fibre per 100g, and look at the price per kilo rather than the price per pack. If the own-label version tastes good to you, keep buying it.

Do I need protein products to get enough protein?

Most people don’t. Eggs, fish, chicken, beans, lentils, tofu, Greek yoghurt and cheese can cover what you need across the day, especially if each meal includes some protein. Protein products can be handy for some people, like athletes or anyone recovering from illness, but you can eat well without them. I’ve written about how much protein you need, and the best food sources, in Protein Hype vs Protein Truth.
