Registered Nutritionist Warns Britain’s Protein Bar Habit Isn’t as Healthy as It Looks

New data from Retail and Wholesale shows that 79% of consumers are more likely to trust snacks with fewer and recognisable ingredients, while 40% say protein snacks are too expensive.

With most shoppers gravitating toward snacks that are genuine and straightforward, recipe box delivery service Green Chef is calling for a clearer conversation around protein products and a shift toward simple options that genuinely support health.

It’s clear people want food that feels honest. When a snack has a manageable list of ingredients and does not leave you wondering what half of them are, you start from a place of trust.

Registered Nutritionist and Recipe Development Manager at Green Chef, Lily Keeling, has shared a roundup of protein-rich snacks that do not rely on complicated labelling or persuasive marketing tactics.

Lily says the report mirrors what she sees in her work. “Protein has become a kind of shorthand for better choices, but the reality is more nuanced. You can make your own with a few ingredients and good quality protein powder, or there are plenty of quick protein-packed snacks if time is tight.”

“Protein bars often seem like an easy or healthy fix, but what’s inside can vary wildly,” she says. “Not all of them are unhealthy, but most rely on sweeteners, binding agents or preservatives that could upset digestion. And some contain as much sugar as a regular chocolate bar.”

A round-up of protein-rich snacks that keep things simple

Lily has shared her go-to options that can stand in for typical protein bars. Some are shop-bought and some can be prepared in minutes at home.

She emphasises, “Many people assume protein bars automatically mean healthy, but a single bar can mask 10 or more processed ingredients you may not even recognise. Spreading protein through real foods is more transparent, giving you protein without hidden additives.”

1. Greek yoghurt with berries and chia

A 150g serving of Greek yoghurt contains around 10g of protein, and adding a handful of berries plus a teaspoon of chia seeds brings extra fibre and natural sweetness.

Lily describes it as “one of the most balanced protein-based snacks for everyday eating” because it combines protein, slow-release carbohydrates and texture in a single bite. She emphasises that it is quick to prepare, requires no additives, and can be adjusted to taste or portion size.

While slightly lower in protein than a typical bar, she notes the combination offers a satisfying alternative that keeps energy levels steady.

2. Cottage cheese on wholegrain crackers

A typical 100–150 g serving of cottage cheese contains roughly 11–20g of protein. Add a handful of seeded crackers, which are also easy to make at home if you want to avoid additives, and you’ve got a textured, balanced snack.

Lily describes it as a “steady-release protein source” as it contains casein, a type of protein that fills you without spiking hunger again quickly. She also points out that, unlike many bars, there’s no need for stabilisers or artificial binders, just dairy and grains.

3. Boiled eggs with smoked paprika

Two medium boiled eggs offer around 12g of protein in total. Lily calls eggs “one of the simplest, most reliable sources of complete protein.”

Adding a sprinkle of smoked paprika or sumac enhances the flavour without compromising purity.

She argues that for someone who wants a no-nonsense, high-protein snack, this is a better bet than picking up a bar with long ingredient lists.

4. Roasted chickpeas

A 150 g serving of roasted chickpeas (homemade or shop-bought) provides about 10–12 g of protein, plus fibre.

Lily argues these satisfy the crunch craving that many people want when looking for a snack. “They feel like the perfect snack, crunchy and satisfying, and you can batch cook them at the start of the week to have on hand whenever you’re looking for a quick protein hit.”

She adds that because they are minimally processed, their ingredients are transparent, unlike some bars, which pack in a long list of additives.

5. Edamame beans with sea salt

Around 100g of cooked edamame has roughly 11g of protein.

Lily recommends them as a “grazing snack that’s both light and filling, perfect when you want something quick that doesn’t compromise on protein. Introducing edamame into your diet gradually allows your gut to adjust to the increased fibre and other components in unprocessed soy.”

She also notes that preparing them from frozen is easy and far cleaner than grabbing a heavily processed protein bar.

6. Apple slices with nut butter

An apple with about two tablespoons of nut butter delivers roughly 6–8g of protein, depending on the nut butter type (for example, almond or peanut).

Lily highlights how this duo is both simple and nutritious: “You get a satisfying mix of natural sugars from the fruit and fats and protein from the nut butter. By choosing a nut butter made from just nuts (and perhaps a pinch of salt), you avoid artificial additives.”

She says this snack can be just as effective as a protein bar for sustaining energy, especially when you want something clean and familiar.

7. Tinned fish on toast

A typical 125 g tin of sardines or mackerel contains around 25–28 g of protein, depending on the brand.

On a slice of wholegrain toast, that becomes a protein-rich and omega-3-packed snack. Lily loves this one for being “nutritious, no-fuss, and deeply satisfying.”

This combo outpaces many protein bars both in terms of quality and nutrient density. She adds, “It takes almost no more effort than making a regular slice of toast, yet gives you a serious hit of protein and omega-3s that most snacks simply cannot match.”
