THE STORY BEHIND YOUR SLICE
In the BBC documentary Irresistible: Why We Can’t Stop Eating, Dr Chris van Tulleken explores a striking comparison: a homemade lemon cake with a production cost of £4.86, versus just 23p for an industrial version.
This independent programme offers a revealing look at how ingredients, shelf life and cost shape the food we buy. It’s a useful starting point for understanding what goes into a SRSLY loaf, and why it costs more.

A recipe starts with a purpose. Change the purpose, and you change what goes into it.
The BBC’s lemon-cake example puts a price on that difference.
THE HOMEMADE CAKE
A homemade cake starts with familiar ingredients: flour, eggs, butter and fresh lemon. Milled, grated, squeezed and mixed. The purpose is personal: make something for people you care about.
Specialist food can start with a personal need too, such as a particular balance of carbohydrate, protein and fibre. That changes the recipe, and what its ingredients cost.
THE INDUSTRIAL CAKE
A commercial recipe may need to hit a low price point, behave consistently in a factory and last weeks or months on a shelf. This example shows 30 days.
Cheaper fats, syrups and starches, supported by emulsifiers, stabilisers, preservatives and flavourings, help make that possible. The recipe is being engineered to meet a different set of priorities.
Source: BBC, Irresistible: Why We Can’t Stop Eating, approximately 21:09–23:05. These are the programme’s stated production costs and shelf lives for two cake examples, not retail prices, bread costs or a health comparison.
THE SRSLY VIEW
When the brief is the lowest cost and the longest shelf life, the person eating it risks becoming an afterthought.
We believe nutrition should be a starting point, not whatever is left after the cost-cutting. We should be challenging the role of this food system in the obesity and type 2 diabetes crises, rather than treating cheap production as the only measure of success.
Health belongs in the recipe brief. Right at the start.
Higher consumption of ultra-processed foods is associated with higher risks of obesity and type 2 diabetes. SACN’s 2025 evidence review also notes that most evidence is observational and that different food groups show different associations. This does not establish that individual additives, this cake or all processed breads cause these conditions. Read the evidence ↗
NOW LOOK AT WHAT GOES INTO EACH
The programme’s two ingredient lists, shown below in our own design.
THE INDUSTRIAL EXAMPLE
THE HOMEMADE EXAMPLE
Ingredient lists from the BBC programme, numbered for readability with grouped ingredients kept together. Images are original AI-created illustrations, not BBC stills or photographs of the actual recipes or factories. These are cake examples, not SRSLY recipes; a homemade cake is not automatically healthier, and list length alone does not determine nutritional quality.
NOW, PUT IT ALL ON THE TABLE
From familiar kitchen staples to a longer spread of powders, syrups, fats and flavouring. Seeing the ingredients laid out makes the change in the recipe tangible.

NOW, LET’S TALK SRSLY
Toast worth getting up for. A bagel piled with your favourite filling. A sandwich that feels like lunch again.
Our breads, bagels, rolls and wraps start with a different nutritional brief. The ingredients have to deliver on that brief, and still make food you look forward to eating.
Here’s what goes into it ↓Explore our high-protein bakery ↗
Change the balance of carbohydrate, protein and fibre, and the whole recipe has to work differently. Here’s how that looks in our original sliced bread.
Protein-containing ingredients that help build structure and texture. The loaf still needs to rise, hold together and make a proper sandwich.
Fibre, texture and character in the blend. They help shape a loaf with a different nutritional balance from an everyday white bread.
Water, oil, yeast and the other ingredients all have a job. The result needs to slice, toast and taste good, as well as deliver the numbers.
WHY THIS CHANGES THE COST
Protein and fibre ingredients have different costs and sourcing requirements from standard bread flour. Changing the blend changes the economics.
A different dough needs development and testing to get the rise, crumb and eating experience right. Nutrition is only part of the brief.
Mass-market loaves spread costs across huge volumes. Specialist bakery generally has fewer units over which to spread development, production and handling costs.
That’s the work behind the slice: a different recipe, made for a different purpose.
These are qualitative cost drivers, not an itemised breakdown of SRSLY’s manufacturing costs.
Water, wheat gluten, egg, brown flaxseed, oat fibre, rapeseed oil, wheat flour (with calcium, iron, niacin, thiamine), yeast, yeast activator: inverted sugar syrup, salt, thickener: xanthan gum, sweetener: erythritol, flour treatment agent: ascorbic acid, preservative: calcium propionate.

AND NEXT TO AN EVERYDAY WHITE LOAF?
Here’s our original sliced bread alongside Warburtons Medium Toastie (800g), a familiar white-bread example.
| Nutrition | SRSLYOriginal sliced bread | WarburtonsMedium Toastie (800g) |
|---|---|---|
| Carbohydrate | 3.6g | 46.4g |
| Protein | 22.2g | 9.1g |
| Fibre | 14.8g | 2.3g |
| Energy | 216 kcal | 244 kcal |
| Sugars | 0.9g | 3.0g |
| Fat | 9.0g | 2.0g |
| Saturates | 1.0g | 0.5g |
| Salt | 0.92g | 0.98g |
One named white loaf, not a market average. Wholemeal and other specialist breads differ. Equal weights make this a fair comparison: a SRSLY slice is 20g; Warburtons declares an average slice of 40.3g.

A higher price isn’t proof that a food is better for everyone. What matters is whether it does the job you need.
We make bread for people who want a different balance of carbohydrate, protein and fibre, without giving up familiar meals.
No. It is a formulated, processed food, and our recipe includes functional ingredients and a preservative. We don’t describe it as unprocessed, additive-free or “chemical-free”. Our case is about the finished nutritional profile, taste and usefulness.
No. The documentary is independent of SRSLY. We recommend it as food for thought, not as evidence of an endorsement or an assessment of our bread.
It depends on what you want from your food, your preferences and your budget. Read the ingredients and nutrition, compare portions and choose what works for you. Our bread contains wheat, egg and oats and is not gluten-free.
BACK TO WHAT MATTERS
That’s what we’re working for. Familiar food, made to fit a different nutritional brief, and a straight answer about what goes into it.
