Easy. No fridge needed. No prep required. And they actually taste good.
The best healthy work snacks are high in protein, fat, and fibre, require no refrigeration, and won't send your blood sugar into freefall before your most important meeting of the day.
Whether you're after healthy office snacks for a team meeting, something to keep in your desk drawer, or healthy snacks to stock the office kitchen for employees — I’ve got you covered.
The snacks you choose at work can be the difference between a productive afternoon and one spent staring blankly at your screen in a sugar-induced haze, desperately fighting the urge to nap under your desk at 4pm.
As a workplace nutritionist — delivering nutrition workshops and 1-2-1 sessions with clients across the UK — I regularly see one of two patterns when it comes to snacking at work:
People opting for what they think are healthy snacks, only to unknowingly pump refined carbs and hidden sugars into their bodies, or
Those whose blood glucose is so out of whack that the vending machine chocolate bar or the office biscuit tin feel genuinely impossible to resist.
The sad reality is that the vast majority of snacks on supermarket shelves won't positively contribute to your health, short or long-term.
I've spent many an hour doing the legwork — trawling through supermarket shelves and scrutinising labels (looking very much like someone with a severe allergy) — to find the few genuine gems I'd actually recommend as healthy snacks for work.
So here it is: my guide to the best healthy snacks for work available in UK supermarkets right now, including plenty of healthy snacks for office workers with no fridge.
Bonus: they're all low GL snacks, meaning they'll keep your blood sugar stable rather than sending you into a sugar spiral that has you eyeing up your colleague's desk biscuits at 3pm.
They require zero prep. And they all taste genuinely good — which, let's be honest, is the most important thing.
Contents
Should I Even Be Snacking at Work?
Honestly? Ideally not (sorry!)— and here's why. If your meals are genuinely well-balanced (think good ratios of fibre, protein and fat), they should keep you comfortably energised and satiated for around 3–4 hours.
There are also real benefits to giving your digestive system a proper rest between meals rather than keeping it in a constant state of processing.
But — and it's a big but — long work days, chronic stress and the reality of modern office life make blood glucose management genuinely tricky. Stress plays havoc with your blood sugar regulation, making you more susceptible to energy dips even when you've eaten a decent lunch.
This is where a well-chosen snack earns its place. Having a stash of easy healthy work snacks within arm's reach means you're never caught short — because the key is having the right options available before your blood sugar drops too low and ghrelin (your hunger hormone) kicks in.
By that point you're not making a considered choice, you're just grabbing the nearest sweet/carby snack- usually the office biscuit tin.
Stock up on healthy snacks to take to work like these, keep them in your desk drawer, and you'll short-circuit that whole sorry cycle before it starts.
Why Your Snack Choice Actually Matters
This isn't just about avoiding a sugar crash (though that's a big one). The right healthy work snack ideas can make a measurable difference to how you feel and perform:
🧠 Cognition and Focus — stable blood glucose means your brain gets a consistent fuel supply. Spikes and crashes make it biologically harder to concentrate, make decisions and think creatively, no matter how motivated you are.
Certain snack foods (hello cocoa!) also contain flavonoids that improve blood flow to the brain, alongside brain-supporting nutrients including Vitamin C, B12, B6 and healthy medium-chain triglycerides (MCTs).
😮💨 Stress Resilience — stress and blood glucose are more closely linked than most people realise. Every time your blood sugar drops sharply, your body triggers a cortisol response to bring it back up — meaning poor snack choices are literally adding to your physiological stress load throughout the day.
Low GI snacks that slow glucose absorption help break that cortisol-glucose cycle. The right snacks can also top up your magnesium and vitamin C — the first nutrients depleted during a stressful period at work.
⚡ Sustained Afternoon Energy — The 3pm slump is not inevitable — research consistently shows it's largely a consequence of what you ate at lunch and what you've been snacking on throughout the day.
A 2022 meta-analysis found that cognitive performance was measurably better two hours after a low GL meal compared to a high GL one — particularly in adults under 35.
The right desk snacks keep your energy curve smooth rather than resembling a rollercoaster.
They can also supply antioxidants and B vitamins to help power healthy mitochondria — the energy factories inside your cells.

How I've Chosen These Healthy Supermarket Snacks — My Checklist
I didn't just grab whatever had "natural" or "high protein" splashed across the front – in fact I tried to steer clear of this marketing propaganda!
Here's the checklist of exactly what every snack on this list had to pass:
N.B This was hard! And in all honestly, some of the snacks took some of these criteria with a small pinch of salt - I'll flag where!
✅ Low Sugar — under 6g per serving was the aim (equivalent to 1.5 tsps) . Hidden sugars, in all their guises, are everywhere in so-called healthy snacks and are the number one culprit behind that afternoon energy crash.
✅ Good Buffers — meaningful levels of fibre (ideally 3g+ per serving), protein (5g+ per serving) and/or natural fats to slow glucose absorption and keep you genuinely satisfied.
✅ Low GL not just low GI — glycaemic load takes portion size into account, making it a far more useful real-world measure of how a snack will actually affect your blood sugar.
✅ No Seed Oils — sunflower oil, rapeseed oil, palm oil, canola oil. If it's in there, it didn't make the list. These heavily processed oils contribute to chronic inflammation and cognitive decline.
✅ No Emulsifiers — watch out for E471, E472e, E481 and friends. Your gut lining will thank you.
✅ Minimally Processed — if the ingredients list reads like a chemistry experiment, it didn't make the cut.
✅ Available in UK Supermarkets — no obscure health food shops or online-only brands. These had to be in at least one major UK supermarket, ideally multiple.
✅ Actually Tasty — arguably the most important criterion, because as I know all too well, healthy eating advice only works if you'd actually choose to eat it.
The Top 11 Healthy Work Snacks
1. Brave Sea Salt Crunchy Chickpeas
📍 Where to buy: Sainsbury's, Tesco, Waitrose, Ocado
Nutrient | Per 35g serving |
Fibre | 5.2g |
Fat | 3.7g |
Protein | 7.1g |
Carbohydrate | 16g |
Sugar | 0.6g |
WHY IT MADE THE LIST
With just three ingredients, this is a pretty healthy snack choice. Chickpeas are a brilliant whole food that give you a good hit of protein and fibre without excessive carbohydrates — meaning no big glucose spike and no afternoon slump.
The one compromise here is rapeseed oil, which is a pro-inflammatory seed oil, but this is the trade-off you'll have to make if you want a convenient pre-made salty, crunchy snack!
(see recipe below for non seed oil version!)
Chickpeas are rich in folate and zinc — two nutrients critical for serotonin production and stress regulation that are commonly depleted in busy, high-pressure professionals.
Their prebiotic fibre also feeds your beneficial gut bacteria, directly supporting the gut-brain axis that regulates mood and anxiety.
NUTRITION HIGHLIGHTS
• 💪 Plant-based protein punch — chickpeas deliver a solid hit of protein to stabilise blood sugar and keep hunger at bay between meals
• 🌿 Prebiotic fibre — feeds your beneficial gut bacteria directly, supporting the gut-brain axis that regulates mood, anxiety and mental resilience
• 🦴 Rich in folate and zinc — two nutrients critical for serotonin production and stress regulation that are commonly depleted in busy professionals
MY VERDICT
Before buying these, I tried making roasted chickpeas myself — and found it genuinely difficult to achieve that perfect crunch without drying them out or burning them. These ones by Brave Foods nail it.
The right amount of crunch, and the sea salt brings out the mild, nutty flavour of the chickpeas beautifully.
These aren't going to satisfy sweet cravings, but when you're genuinely a bit peckish at your desk or on the road with work, these are a great option to have to hand. The fibre and protein kept me full — no reaching for another snack half an hour later.
2. Bear Fruit Coconut Chips
📍 Where to buy: Sainsbury's, Tesco, Waitrose, Boots, and most major UK supermarkets.
Nutrient | Per 18g serving |
Fibre | 4g |
Fat | 9.5g |
Protein | 0.9g |
Carbohydrate | 6.8g |
Sugar | 4.7g |
WHY IT MADE THE LIST
When looking at the "healthy snack" section in supermarkets you are faced with an increasingly large range of dried fruit — and unfortunately, 99% of these didn't make the cut, largely because you'll be consuming a whole lot more sugar in one go than you normally would when eating fresh fruit. Most are 80%+ sugar (including the rest of the Bear Fruit range).
But these bad boys are an anomaly. They are considerably lower in sugar and much higher in natural fats, creating a beautifully sweet, fairly natural, low-UPF snack that isn't going to send your blood sugar soaring.
The medium-chain fatty acids (MCTs) from the coconut provide excellent brain fuel, having been shown in research to improve cognitive function, memory and focus . They do have a small amount of added coconut blossom sugar which makes them very moreish — but at a level that won't cause too much disruption to your energy levels, thanks in large part to the accompanying fat content.
NUTRITION HIGHLIGHTS
• ⚡ MCT brain fuel — coconut's medium-chain fats are rapidly converted to energy by the liver, providing quick, clean fuel for the brain without the blood sugar spike
• 🌿 Gut-friendly fibre — 4g of fibre per pack supports a healthy microbiome and keeps digestion moving, which directly influences mood and mental clarity
• 📉 Naturally lower sugar — a satisfying, crunchy sweet fix that won't trigger the insulin spike and energy crash of conventional sweet snacks
MY VERDICT
I discovered these originally as a snack for my kids (who absolutely love them) but having had a nibble myself, I've become quite the fan!
They are just the right amount of crunchy, sweet and coconutty and are incredibly moreish. I always have the first handful not expecting too much and I'm always nicely reminded how good they are!
The little chips also make them a great healthy work snack to pick at while you're at your desk and those stress cravings kick-in!
3. Boundless Activated Nuts and Seeds — Orange and Maple Syrup
📍 Where to buy: Waitrose, Ocado, Holland & Barrett, and selected independent health food stores. Also available on Amazon.
Nutrient | Per 25g serving |
Fibre | 1.9g |
Fat | 12.8g |
Protein | 5.7g |
Carbohydrate | 2.9g |
Sugar | 2.1g |
WHY IT MADE THE LIST
With nuts and seeds as the core base, nutritionally these make a brilliant snack. The ratios of protein, fat, carbs and fibre are excellent and will provide your brain and body with a steady release of energy through the afternoon.
They contain one of my favourite nuts — pecans — which are exceptionally high in antioxidants, including vitamin E and polyphenols, which fight oxidative stress, combat chronic inflammation and protect cells from damage.
Crucially, all the nuts and seeds are activated — meaning they have been soaked and slowly dehydrated to neutralise phytic acid, a natural compound that otherwise blocks your body from absorbing key mood and energy nutrients like zinc, magnesium and iron. It's a small but powerful difference: same snack, significantly more nutrition actually making it into your body.
The sweetness comes from maple syrup rather than refined white sugar. Maple syrup has a lower glycaemic index, causing a slower, gentler rise in blood glucose rather than a sharp spike and crash. It also contains small amounts of zinc and manganese — making it a marginally more nutritious sweetener overall.
NUTRITION HIGHLIGHTS
• 🧘 Magnesium-packed — almonds and pumpkin seeds are among the best dietary sources of magnesium, one of the first minerals depleted by stress
• 🧠 Omega-3 rich — pecans & seeds deliver plant-based omega-3s essential for reducing neuroinflammation and keeping mood stable
• 🌿 Gut-friendly and activated — soaking and dehydrating breaks down the enzyme inhibitors that make nuts hard to digest, meaning your gut can extract maximum benefit from every handful
MY VERDICT
These were a nice surprise — far tastier than I expected for a pack of nuts and seeds! The contents are a decent size too, no bag of crumbs like some similar products can be. I couldn't particularly taste the orange, but it's a really enjoyable snack regardless.
Great for nibbling on when you're bored in the office and need something to help you regain focus!
I'll be keeping these permanently in my work bag — brilliant compact snack for travelling when you’re on the road and want to avoid the service station UPF frenzy.
Just a shame these healthy work snacks aren’t available at more of the supermarkets.

4. Rude Health High Protein Lentil Triangles
📍 Where to buy: Waitrose, Sainsbury's, Ocado, Holland & Barrett, and most health food stores.
Nutrient | Per 35g serving |
Fibre | 3.4g |
Fat | 3.5g |
Protein | 9.1g |
Carbohydrate | 16g |
Sugar | <0.5g |
WHY IT MADE THE LIST
For a crisp-style snack, this offers a pretty impressive combo of macros — decent protein and fibre that actually leave you satisfied, unlike the plethora of crisps and rice cakes in the supermarket.
The "high protein" claim comes from 63% lentils, which is a far better source of protein than the soy protein isolates usually behind that label.
Most lentil-based crisps sneakily have high levels of other processed carbs such as corn or rice as the key ingredient — the carbohydrate content of these is not too bad for this style of snack.
Yes, they do contain corn oil (likely the processed kind) — that's the one compromise here — but when you're craving something crunchy and salty, or wanting something that isn't a carrot baton to have with a dip, these are a solid choice.
Lentils are particularly rich in folate (B9) — critical for serotonin and dopamine production iron — supports oxygen transport and energy; and zinc — plays a key role in mood regulation and is frequently depleted by chronic stress.
NUTRITION HIGHLIGHTS
• 🌱 Rich in folate (B9) — critical for serotonin and dopamine production, often low in people experiencing low mood or fatigue
• 🩸 Good source of iron — supports oxygen transport and energy; deficiency is one of the most common causes of brain fog and exhaustion, especially in women
• 💪 Plant-based protein — keeps you fuller for longer and stabilises blood sugar between meals
MY VERDICT
These have more flavour than they look and make a really tasty snack to chomp on when you're craving crisps. I ate most of mine plain (and my kids really enjoyed them too!) but they work brilliantly dipped in something like hummus, guacamole or with cream cheese or nut butter spread on them.
I'll be stocking up on these for my desk drawer for when lunch falls a bit short & you want something a bit carby without the glucose crash.
5. Forest Feast Salted Dark Chocolate Almonds
📍 Where to buy: Waitrose, Sainsbury's, Ocado, Amazon.
Nutrient | Per 30g serving |
Fibre | 1.9g |
Fat | 10.75g |
Protein | 3g |
Carbohydrate | 7.75g |
Sugar | 7g |
WHY IT MADE THE LIST
If you've ever attended any of my nutrition workshops or webinars, you'll know I'm pretty nuts about nuts!
I think they are nature's near-perfect snack, with great ratios of fibre, protein and healthy fats. Almonds in particular are one of the most nutritionally dense nuts offering a brilliant hit of vitamin E, calcium (the highest of any nut!), iron, magnesium and phosphorus.
But I know a lot of people don't find a plain handful of almonds all that exciting as a snack.
But…whack on some dark chocolate and sea salt and the humble almond becomes a genuinely game-changing afternoon pick-me-up.
Although the sugar is on the higher side for this list, it's somewhat counterbalanced by the high levels of natural fats from the nuts and cocoa butter, which help slow gastric emptying and prevent a sudden glucose spike.
One thing to note: they do contain soya lecithin (an emulsifier), but research has shown soya lecithin is one of the only emulsifiers that doesn't appear to cause damage to the gut lining or microbiome — so consider this one a guilt-free pass.
NUTRITION HIGHLIGHTS
• 🍫 Magnesium-rich — supports stress resilience and nervous system calming
• 🌰 Healthy fats and protein — slows sugar absorption for sustained, crash-free energy
• 💪 Antioxidant-packed — dark chocolate's flavonoids reduce neuroinflammation and sharpen focus
MY VERDICT
I'm warning you — these are dangerous. The ratio of chocolate to nut is very generous and they really do satisfy that post-lunch sweet craving.
The sprinkling of sea salt is subtle but adds a lovely balance to the sweetness and makes them incredibly moreish.
The bag supposedly contains four servings but it’s hard to stop! I'd strongly recommend decanting a generous handful into a bowl rather than working through the bag!
6. M&S Super Seeded Crackers (Nutrient Dense Range)
📍 Where to buy: Marks & Spencer stores and Ocado.
Nutrient | Per 3 crackers |
Fibre | 3.3g |
Fat | 9g |
Protein | 4.6g |
Carbohydrate | 0.3g |
Sugar | 0.3g |
WHY IT MADE THE LIST
I'm a big fan of M&S's Nutrient Dense range — and I don't often say that about supermarket health ranges! This cracker has made the list because it is impressively high in healthy fats, protein and fibre, without any UPF unnecessaries.
It ticks every box on my checklist and is a brilliant alternative to rice cakes, Ryvita and oatcakes — which may seem healthy but have extremely high levels of processed carbohydrates, making them a surprisingly significant blood sugar hit.
These crackers are essentially just seeds and psyllium husk, providing a hit of nutrients including vitamin E, magnesium and B6 — all essential for a healthy nervous system.
Sunflower seeds are particularly high in vitamin E (a powerful antioxidant that protects brain cells from oxidative stress), magnesium and B6 (critical for serotonin and dopamine production).
Sesame seeds are one of the richest plant-based sources of calcium and zinc — essential for mood regulation and frequently depleted by stress.
NUTRITION HIGHLIGHTS
• 🌱 Over 90% seeds — sunflower, sesame and linseed mean almost every bite delivers real nutritional value, unlike conventional crackers which are largely refined flour and empty carbs
• 💩 Gut-health hero — psyllium husk is one of the most effective prebiotic fibres for feeding beneficial gut bacteria, supporting the gut-brain connection that directly influences mood and anxiety
• 📉 Blood sugar stable — just 3 crackers deliver 3.3g fibre and 4.6g protein, making these a genuinely smart swap for rice cakes or standard crackers that spike and crash
MY VERDICT
These are quite a delicate snack with a natural, earthy flavour and a satisfying crunch. They're actually good enough with just butter spread on them but are also brilliant topped with avocado, brie or hummus.
I also tried them with Nut Blend’s cacao, cashew and almond nut butter — great combo -absolutely recommended for an extra nutrient & taste boost. It made the crackers into an almost sweet treat!
I was also nicely surprised that these seeded crackers are not actually too crumbly, so they won't decimate your keyboard if you do decide to nibble at your desk. Not that that is something I would ever do.
These are great to keep in your office as unlike bread, they last a long time and are a great thing to use as a makeshift base when time is tight & you’re running low on supplies.
7. Serious Pig Snacking Cheese
📍 Where to buy: Waitrose, Sainsbury's, Ocado, and some Tesco stores. Also available at many delis and independent food shops.
Nutrient | Per 24g serving |
Fibre | 0g |
Fat | 10g |
Protein | 11g |
Carbohydrate | 0g |
Sugar | 0g |
WHY IT MADE THE LIST
One ingredient — Italian Hard Cheese. That's it. As a grab-and-go snack, it doesn't get much cleaner than this.
These offer high levels of protein and natural fat to keep you genuinely satisfied, with absolutely zero risk of a blood glucose spike — making them a perfect option for anyone managing their blood sugar closely, including those with diabetes or following a low-carb or keto diet.
They are also a great source of calcium, which is not only essential for maintaining strong bones and teeth but plays a critical role in nerve transmission, muscle contraction and overall nervous system function.
NUTRITION HIGHLIGHTS
• 🧀 High protein, zero carbs — a proper fistful of protein to keep hunger and blood glucose stable right through to your next meal
• 🦴 Calcium-rich — supports nervous system function and muscle health, not just bones
• 🧠 Natural fats — slows glucose absorption and helps your brain stay sharp and focused through the afternoon
MY VERDICT
These are super cheesy — but in a genuinely tasty way! If you're a cheese fan, chances are you'll be all over these.
They are the right amount of crunchy and salty, and I've heard they go brilliantly with a Friday night beer. Apparently.
8. Itsu Crispy Seaweed Thins — Sweet Soy
📍 Where to buy: Sainsbury's, Tesco, Waitrose, Morrisons, Ocado.
Nutrient | Per 5g serving |
Fibre | 1.3g |
Fat | 1.6g |
Protein | 1.1g |
Carbohydrate | <0.5g |
Sugar | <0.5g |
WHY IT MADE THE LIST
Yes, this one does contain two of my red flag ingredients (corn oil and maltodextrin) but…seaweed is such an underrated and nutritionally invaluable food that I think most of us would genuinely benefit from eating more of it — and this snack is thankfully available in most UK supermarkets, unlike a lot of other seaweed products.
Just a single 5g serving contributes 150% of our RDA of vitamin B12 and 61% of our RDA of iodine — both energy heroes and both frequently depleted in many of us, especially vegans.
Iodine is essential for thyroid function, which directly regulates your energy levels and metabolism. B12 deficiency is one of the most common — and most overlooked — causes of fatigue and low mood in the workplace.
NUTRITION HIGHLIGHTS
• 🌊 Iodine-rich — one of the best dietary sources of iodine, essential for thyroid function which directly regulates your energy levels and metabolism
• 💊 150% RDA of vitamin B12 per serving — alongside vitamins K and trace minerals that are almost impossible to get from land-based foods. Especially valuable for vegans.
• 🩸 Blood glucose friendly — virtually zero sugar despite the sweet soy flavour, making these a smart swap for crisps or crackers when the afternoon munch urge hits
MY VERDICT
For an extremely thin bit of seaweed, these are incredibly tasty and are the perfect combo of salty and sweet.
I'll be honest — these don't fill you up in any meaningful way, so you'll likely want to pair them with something else (a piece of fruit and some nuts maybe) if you're looking to address actual hunger.
But for that mid-afternoon moment when you want to munch on something when in truth you’re not actually hungry? They are absolutely perfect.
9. Cheesestring (Original)
📍 Where to buy: Tesco, Sainsbury's, Asda, Morrisons, Waitrose, Ocado.
Nutrient | Per 21g stick |
Fibre | 0g |
Fat | 4.5g |
Protein | 5g |
Carbohydrate | 0.2g |
Sugar | 0.2g |
WHY IT MADE THE LIST
Yes, you read that right.
So I bet you didn’t think this one would make the cut?! I didn’t either until I looked on the back and did a bit of digging.
Turns out this kid-friendly stringy cheese is genuinely one of the cleanest, most convenient desk snacks out there.
Made primarily from just pasteurised cheese, it delivers a solid hit of protein and natural fat with virtually zero carbohydrate or sugar. There is no risk of a blood glucose spike, it requires no prep, no fridge for short periods, and it's perfectly portion-controlled.
Cheesestrings do contain acidity regulators — citric acid and lactic acid — to preserve freshness, but with medium fat hard cheese as the base ingredient and added vitamins B6, B12 and D, the extras are fairly innocuous and the overall ingredient list is refreshingly short for a packaged snack.
So, despite the pretty ‘Extra’ marketing campaigns (which my daughters are enthralled by), Cheesestrings are essentially mozzarella that's been stretched to create the stringy texture.
NUTRITION HIGHLIGHTS
• 🧀 Surprisingly high protein for the size — 5g per stick with virtually zero sugar, for stable blood glucose and genuine satiety
• 🦴 Calcium and phosphorus — supports bone density, nerve function and energy metabolism
• ⚡ Ultra convenient — no fridge needed for short periods, zero prep, perfectly portioned for a desk drawer or work bag
MY VERDICT
Look — there's something oddly satisfying about peeling a Cheesestring, (although personally the idea of using my nails to ‘peel’ the cheese creeps me out!)
It does genuinely hit the spot when you want something savoury and creamy without eating a whole block of cheddar.
And let’s be honest there’s something vaguely comically about whipping out a Cheesestring in the middle of a meeting – dare you to keep a straight face.

10. Green & Black's 85% Cocoa Dark Chocolate
📍 Where to buy: Tesco, Sainsbury's, Waitrose, Asda, Morrisons, Ocado
Nutrient | Per 18g serving (3 squares) |
Fibre | 2.3g |
Fat | 8.9g |
Protein | 1.8g |
Carbohydrate | 4.2g |
Sugar | 2.6g |
WHY IT MADE THE LIST
If I showed you those macronutrients without telling you what they were from, I very much doubt you'd guess chocolate.
This 85% cocoa bar actually offers more fibre per serving than a portion of broccoli, a decent hit of natural fats that keeps you feeling full, and a sugar content that stays low enough to feel genuinely indulgent without the blood glucose consequences.
The high cocoa content delivers a concentrated source of flavanols — powerful antioxidants that increase blood flow to the brain, sharpen focus and protect against the neuroinflammation that quietly drives low mood and cognitive decline.
Raw cacao at 85% is one of the most concentrated dietary sources of flavanols found in any everyday food.
A placebo-controlled study published in the Journal of the American College of Cardiology found that men who consumed flavonoid-rich dark chocolate showed significantly lower cortisol and adrenaline levels after a psychosocial stress test — suggesting that a square or two of 85% is a genuinely evidence-based stress management tool.
It's also organic. Virtuous on all counts.
NUTRITION HIGHLIGHTS
• 🧠 Brain-boosting flavanols — cacao's powerful antioxidants increase blood flow to the brain, sharpening focus and protecting against the neuroinflammation linked to low mood
• 🎯 Magnesium-rich — dark chocolate is one of the richest dietary sources of magnesium, the mineral most depleted by stress and most critical for nervous system calm
• 🧘 Clinically proven to lower cortisol — a placebo-controlled study found that men consuming flavonoid-rich dark chocolate showed significantly reduced cortisol and adrenaline levels after a stress test
MY VERDICT
I’ve got to be honest, this is my go-to most days, I get through a lot of it!
It really satisfies that need for something sweet and creamy in the afternoon yet doesn't flood my blood with glucose.
It has a really nice rich, deep flavour without being overly bitter — which a lot of ‘proper’ dark chocolates can be. The fact it's organic makes it an even more virtuous choice. Highly recommended.
(I’m also a big fan of Sainsbury’s Taste The Difference 90% choc 👌)
11. The Curators Original Beef Biltong
📍 Where to buy: Sainsbury's, Tesco, Waitrose, Asda, Ocado
Nutrient | Per 25g serving |
Fibre | <0.1g |
Fat | 0.9g |
Protein | 13g |
Carbohydrate | 0.53g |
Sugar | 0.5g |
WHY IT MADE THE LIST
As a high-protein, meat-based snack this was one of the healthiest options I could find in the supermarket.
It is nitrate-free and contains relatively few additives compared to all the other jerky and biltong products on the shelves. If you're looking for a snack that will meaningfully contribute to your daily protein intake, this is the one — giving you 13g protein per serving, equivalent to two large eggs.
Biltong is rich in iron and zinc, two nutrients that are frequently depleted by chronic stress and are critical for energy, immune function and mood regulation.
For more on how stress and nutrition interact in the workplace, see our Workplace Stress and Burnout workshop.
NUTRITION HIGHLIGHTS
• 💪 13g of protein per 25g pack — a powerful satiety signal that stabilises blood sugar, releases GLP-1 and keeps hunger at bay right through the afternoon
• 🩸 Rich in iron and zinc — two nutrients frequently depleted by stress, critical for energy, immune function and mood regulation
• 🚫 No added sugar or nitrates — none of the hidden nasties that trigger the blood glucose spike and crash you're trying to avoid
MY VERDICT
I wouldn't normally opt for this kind of snack but as one that is relatively natural (as far as mass-produced packaged snacks go) this is pretty good.
The flavour is good — not too strong — and it would make a great addition to a lunch that's lacking in protein. It's quite chewy but in a mostly satisfying way. It also lasts a long time without the fridge until opened, so worth keeping a few in your desk drawer for when you need a protein hit.

Sugar's Many Disguises — The Hidden Sugar Hit List in so-called ‘Healthy Snacks’
Sugar doesn't always announce itself. While it's easy to spot in sweets and fizzy drinks, the most disruptive sources for your energy and mood are often hiding in plain sight — in your lunchtime soup, your "healthy" granola bar, your flavoured yoghurt, your protein shake.
These hidden sugars cause the same blood glucose spike and subsequent crash as the obvious ones, triggering the anxiety, brain fog and fatigue that make afternoons feel like a real slog. Learning to spot them on a label is one of the quickest wins you can make for your energy.
The simple rule: if your snack has more than 6g of sugar per serving — from whatever source, including sneaky maltodextrin — it's worth questioning whether it genuinely belongs in the healthy snack category.
Here are the sweeteners most commonly hiding in "healthy" UK snack bars and what they actually do to your afternoon:
Glucose syrup and glucose-fructose syrup
A fast-releasing sugar that hits your bloodstream almost immediately. Extremely common in cereal bars and "energy" bars. Essentially liquid sugar with a less recognisable name.
Maltodextrin
Particularly sneaky, because it is technically classified as a carbohydrate rather than a sugar. But it has a glycaemic index higher than table sugar (glycemicindex.com). Regularly found in protein bars and "low sugar" snack products — keep a close eye out for this one.
Dextrose
Another name for glucose. Straight blood sugar spike, no delay.
Fruit juice concentrate
Sounds natural, feels virtuous, and behaves almost identically to added sugar in your body. Very common in "natural" and "raw" bars and many "no added sugar" snacks. Don't be fooled.
Honey and agave syrup
Yes, even these. Both still trigger an insulin response. Agave in particular is very high in fructose, which is processed by the liver and can contribute to energy crashes over time. Don't be fooled by the health halo.
"No added sugar" claims
Worth treating with healthy scepticism. It simply means no sugar was added during manufacturing. It says absolutely nothing about naturally occurring sugars from fruit or juice concentrates already in the ingredients.
Always check the actual sugar content per 100g on the back rather than trusting the front of the pack. It may also mean there are artificial sweeteners which I personally think may even be more damaging to our health than good old table sugar – (their potential to disrupt our precious gut microbiome is a big one!) !
UPF Ingredients to Watch Out For in Snack Bars
Walk down the snack aisle of any UK supermarket and you'll find shelves packed with bars, bites and balls positioning themselves as healthy work snack ideas.
Nakd, Eat Natural, Trek, Fulfil, Grenade, RXBAR, KIND, Deliciously Ella bars — the range is genuinely impressive. And I see many of my clients stocking up on these, convinced they're making the healthier choice.
The problem? Nearly all of them are ultra-processed, containing ingredients that drive chronic inflammation, oxidative stress, disrupted gut microbiomes and dysregulated blood glucose.
The cumulative impact on your afternoon performance is more significant than most people realise. A great overview of the science can be found on the British Heart Foundation website.
The protein bar problem
Protein bars have done a brilliant PR job convincing us they're a smart desk snack. But many of them contain highly processed protein powders and ingredients your body doesn't recognise as real food — and I'd argue several are worse for your health than a standard chocolate bar.
Here are some of the most widely available in UK supermarkets right now:
Grenade Carb Killa (Tesco, Sainsbury's, Boots) — contains milk protein isolate, polydextrose, maltitol syrup, emulsifiers and artificial sweeteners including sucralose and acesulfame K. These sweeteners can disrupt gut bacteria and trigger cravings for more sweet food later — the exact opposite of what you want at 3pm.
Fulfil Vitamin and Protein Bar (Tesco, Sainsbury's, Holland & Barrett) — similarly loaded with maltitol and emulsifiers. The high sugar alcohol content commonly causes bloating and digestive discomfort. Not ideal before a 2pm meeting.
Trek Protein Bars (most major supermarkets) — better than many, but several flavours still contain glucose syrup and sunflower oil. Always check the specific flavour rather than trusting the brand.
As a general rule: if the ingredients list runs to more than 10 items and includes words you wouldn't find in your own kitchen, treat it as a processed food — regardless of what the front of the pack claims.
Other UPF red flags to watch for:
Sunflower oil and rapeseed oil — heavily processed, pro-inflammatory seed oils. Widely used but among the most processed ingredients in snack foods.
Emulsifiers (E471, E472, E4760) — used to improve texture but linked to gut inflammation and microbiome disruption. Found in most chocolate-coated bars.
Carrageenan — sounds natural (it comes from seaweed) but has been linked to gut inflammation in several studies.
Artificial flavourings — a catch-all term covering hundreds of chemical compounds. If your snack bar needs artificial flavouring to taste good, the base ingredients aren't doing their job.
Beyond the blood sugar crash, regularly eating ultra-processed snacks contributes to low-grade inflammation, gut disruption and nutrient depletion.
None of it shows up dramatically on a Tuesday afternoon — but it quietly erodes your energy, focus and resilience over time. Small daily choices, big cumulative impact.
Homemade Snack Ideas To Take to Work (For When You Actually Have Time)
Zero prep is the goal — and the snack list above delivers exactly that. But for those occasional Sundays when you do have a spare hour and want to set your work week up properly, these are genuinely worth making.
Batch cook once and eat well all week - whether you are in the office, working away or working from home.
Energy balls
The ultimate prep-ahead snack that you can make tick all the boxes - protein, fibre, natural fat & taste.
Blend ground almonds, nut butter, coconut oil, butter, dried prunes (lower GL than dates) and whatever add-ins you fancy — cacao powder, desiccated coconut, chia seeds, vanilla, cinnamon, seeds, more nuts. Roll into balls, refrigerate for an hour, done.
A batch of 12–15 takes about 20 minutes and lasts all week in the fridge. High in fibre, protein and natural fats — brilliant for keeping blood sugar stable through the afternoon while satisfying sweet cravings.
My current favourite to add in to these gooey beauties is orange peel & cacao powder – gives me that Terry’s choc orange feel, kind of! Check out my own recipe for these 'Orange & Cacao Brain Balls'.
Your own nut mix
Making your own is genuinely better than buying pre-packaged trail mix, which almost always contains dried fruit (concentrated sugar), seed oils or added sweeteners.
Toast a big batch of almonds, walnuts, pumpkin seeds and Brazil nuts in a dry pan, add a pinch of sea salt and smoked paprika, and portion into small bags for the week. A naturally perfect combination of fibre, protein and fat — one of the best low GL snacks you can have at your desk.
If you want to be extra healthy, soak the nuts overnight beforehand to break down phytic acid and tannins, which are "anti-nutrients" that can hinder digestion and mineral absorption.
Roasted chickpeas
A brilliant alternative to crisps for anyone who needs something crunchy and salty in the afternoon.
Drain a tin of chickpeas, pat them very dry (I learnt this the hard way!), toss in just a little extra virgin olive oil, curry powder & sea salt, and roast at 190°C for 30–35 minutes until properly crispy.
High in protein and fibre, genuinely satisfying, and a world away from a rice cake. Store in an airtight container — they'll last 3–4 days.
Dark chocolate and nut slab
Melt good quality dark chocolate (85%+ cocoa), stir through your favourite mixed nuts and seeds — hazelnuts are my personal favourite for that Ferrero Rocher vibe!
Pour onto a lined baking tray, scatter with sea salt flakes and refrigerate until set. Break into pieces and keep in the fridge.
A small square delivers magnesium, healthy fats and antioxidants without the sugar crash. And it tastes brilliant — which matters.
Hummus and veg
Homemade hummus is actually far less faff than people think. In reality, it takes about 5 minutes in a blender with no chopping required — and it's miles better than most supermarket versions, which typically contain sunflower oil.
Blend a tin of chickpeas with tahini, lemon juice, garlic and extra virgin olive oil. That's genuinely it. Pair with cucumber, celery, pepper strips or those M&S seeded crackers (above).
Covers protein, fibre and healthy fat in one snack. Mix it up and add a bit of beetroot for the most vibrant, beautiful hummus you've ever seen!
For HR & People Managers — Healthy Snacks to Stock in Your Office Kitchen
Reading this as an HR or People and Culture manager rather than an individual snacker? This bit's for you.
The ROI case for getting this right
The snacks in your office kitchen right now are either supporting your team's performance or quietly undermining it. There isn't really a neutral option.
Research shows employees with poor diets are 66% more likely to report lost productivity. And the contents of your office snack supply are a direct contributor to that number.
Here's what happens when your team reaches for standard office fare — a biscuit from the tin, crisps from the vending machine, a cereal bar from the kitchen cupboard.
Blood sugar spikes. Insulin floods in. Glucose drops below baseline. Cortisol rises to compensate. The result? Irritability, difficulty concentrating, poor decision-making and that glazed look you'll recognise from every 3pm meeting.
This isn't a motivation problem. It's a biology problem. And it's one of the most straightforwardly fixable issues in your workplace.
Swapping even part of your office snack supply to the options in this guide doesn't require a huge budget overhaul. It requires a slightly more considered supermarket shop.
The difference in afternoon team energy is, in my experience, noticeable within days.
The office vending machine trap
The typical office vending machine is a blood sugar rollercoaster disguised as a convenience.
Standard crisps, chocolate bars and sugary drinks create exactly the cycle above — and because the crash triggers cravings for more of the same, it tends to be self-perpetuating. One Kit Kat at 2:30pm becomes two by Thursday.
Does your office kitchen need a snack audit? I work with HR and People teams to assess their office food environment and make practical, budget-conscious recommendations that people actually use — not just a list of things that sit untouched on a shelf. Get in touch:
Want to Go Beyond the Snack List?
If this has got you thinking about your team's energy and focus more broadly — good. Because better snacks are a great starting point, but they're only one piece of the puzzle.
I run interactive nutrition workshops & healthy eating webinars specifically designed to tackle the 3pm slump & boost cognition of high performing teams— and one of the most popular elements of our in-person seminars is a live tasting table where your team gets to try some of the best healthy snacks for work from this guide.
No death by PowerPoint, no guilt trips — just super practical, science-backed strategies your team will actually remember and use the next day.
