Don’t Be Fooled: Find out how healthy your bread is

Don’t be fooled by appearances – not all bread is as healthy as it claims to be. Whether you’re picking up a loaf from the supermarket or your local artisan bakery, or even baking your own it’s crucial to know if it’s genuinely good for you. Our simple tool cuts through the marketing fluff and gives you an honest assessment of your bread’s healthiness. We’ll help you dig deeper, looking at fibre content, fermentation, flour quality, and potential agrochemical residues. In just a few clicks, you’ll know if your bread supports your well-being – no more falling for clever packaging or buzzwords. Make sure your bread is truly nourishing!

How to use the calculator

  1. Pick up your loaf and examine the ingredients list and nutrition label.
  2. Check for key factors: whole grain content, % fibre content, and see if there are any detail on milling process,
  3. If it does not say regenerative agriculture or organic, then the grains will have been grown conventionally and subject to agrochemical exposure
  4. The list of additives is not all additives I have just listed some but there may be more.
  5. If yeast is mentioned then choose unspecified fermentation
  6. If it says Sourdough and yeast choose unspecified Fermentation
  7. If it says sourdough but not “retarded” or Cold fermented then choose ambient fermentation not specified
  8. If it doesn’t say stoneground flour then assume roller milled flour.
  9. Enter details into the form and click “Calculate Score” for your bread’s health evaluation.
  10. Talk to the baker, look up details on website and dig deeper.

Let me know how you get on. I would be so delighted if you can share the brand and your score with me on comments below on on social media.

Comprehensive Scoring System to Evaluate if Your Bread is Healthy

This diversity is crucial for providing a wide range of nutrients, fibres, and minerals, supporting gut health and nutritional balance.
Fibre content is essential for digestive health and maintaining a healthy gut microbiome.
Stone-ground flour retains more nutrients and has a less disruptive impact on the grain’s natural state.
Flour not treated with agrochemicals is essential for avoiding unnecessary chemical exposure and promoting soil health.
Additives, preservatives, or artificial components detract from the bread’s natural quality and can impact health negatively.
Long fermentation promotes better digestibility and nutrient availability.
Includes seeds, nuts, or legumes, adding valuable nutrients, fibres, and textures.


Key Takeaways

  • Not all bread is as healthy as it appears; it’s vital to assess its nutritional value.
  • Use the Healthy Bread calculator to evaluate your loaf based on ingredients and nutrition labels.
  • Examine key factors like whole grain content, fibre percentage, and milling process for accurate assessment.
  • Enter your bread details into the calculator, then click ‘Calculate Score’ for the health evaluation.
  • Engage with bakers and share your findings with the community to promote awareness.

About Dr Vanessa Kimbell

Dr Vanessa Kimbell is acknowledged as one of the world’s foremost authorities on bread and human health — the first person to hold a doctorate in Baking as Lifestyle Medicine and Preventative Healthcare, and the pioneer who, long before gut health became a mainstream concern, first identified the crucial role bread plays in the gut microbiome and mental wellbeing. A fourth-generation baker of Italian descent, she has been baking sourdough since the age of 11, served her traditional apprenticeship in the Dordogne, and is a time-served, French-trained qualified baker who has worked alongside some of the world’s greatest bakers including Richard Hart and Gabriele Bonci. She has spent four decades asking the questions the food industry preferred no one asked: why was industrial mono bread slowly harming us, and what would it take to make bread that genuinely nourishes?

The answer became her life’s work. As founder and Course Director of The Sourdough School in Northamptonshire — a world-renowned centre of research and education — she has taught bakers from over 84 countries, integrated the BALM (Baking as Lifestyle Medicine) Protocol into NHS clinical practice at Bethlem Royal Hospital, and developed Proven Bread: the first bread built on clinical evidence, personalised to the individual through nutrigenetics and gut microbiome assessment. She delivered the Royal College of General Practitioners‘ approved course in the Nutrition of Bread, has been a regular contributor to BBC Radio 4’s Food Programme for many years, and collaborates with leading scientists and clinicians including Professor Tim Spector — who credits her with teaching people to make the healthiest bread in the world — and Professor David Veale. Named the Sourdough Queen by The Telegraph in 2013, her influence reaches far beyond the classroom — from artisan bakers and healthcare professionals to the world’s leading food scientists and multinational food corporations.

A bestselling international author of five books, her sixth — Proven — publishes in November 2026.

    Really useful and interesting tool to empower people to have a better understanding on what “real” nutritious bread should contain and that so-called “Sourdough” / “Gut-Healthy bread” is typically marketing.

    It is beholden though on the manufacturers that make good quality, nutritious bread, to be more open and transparent of the ingredients used; the percentages, and the method used.

    I am aware that The Berliner bakery White Sourdough loaf, which is sold through Waitrose, is a fairly good nutritious bread using a mix of flours (some organic) and made using a long cold fermentation process. It also has no additives. However there is a difference in the information published on their website (https://bertinetbakery.com/products/sliced-white-sourdough-500g/) to what is published on waitrose’s (https://www.waitrose.com/ecom/products/bertinet-bakery-white-sourdough/575100-595150-595151)

    If I score using the data on their website the bread is scored 10 (Group 4 / UPF) where as using the data on Waitrose’s website the score is 55 (Group 3 – Processed but at the higher end)

    As a baker that uses a mix of white roller milled and freshly milled wholegrain, and a diverse blend as well, I would be interested to be able to input a mix of flours to have a more accurate scoring perhaps.

    Lastly, it was interesting to see that some commercial brands who state they use a range of flours and seeds still only have a low fibre content which may suggest that the inclusion of diverse flours and grains might make up a very small percentage of the overall flour mix.

      Nice calculator but simply giving a score with no scale for reference is not helpful. Is it 50 out of a 100? is a higher score better? who knows. It feels like the score is useless with no scale or detail about what is and is not a good score.

        That’s fair criticism. The scoring does have a scale and interpretation built in — it just isn’t visible until after you calculate – I’ve changed the introduction to incorporate this – hope you approve. !

IBS AWARENESS MONTH Do you suffer from irritable IBS AWARENESS MONTH

Do you suffer from irritable bowel syndrome (IBS)? It can be tough to deal with the uncomfortable symptoms of stomach cramps, constipation, diarrhoea and bloating. But did you know that making dietary changes, such as incorporating sourdough bread into your diet, could help alleviate some of those symptoms?

Studies have shown that sourdough's long, slow fermentation process can reduce IBS symptoms. Plus, during #ibsawarenessmonth, we're exploring how adding different herbs and spices to your sourdough can further improve both the flavour and the digestion of your bread.

Let's talk about gut health, fermentation, and how sourdough can be a delicious and healthy addition to your diet. Join the conversation and share your experiences with IBS and sourdough.

THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME On THE SOURDOUGH SCHOOL – HAND CARVED WOODEN LAME

One of the biggest issues around using a plastic lame to score sourdough, of course, is that eventually the blade will become blunt and the lame could end up in landfill.  So several years ago I talked to my dear friend EJ about developing a lame with a replaceable blade. And he came up with this very beautiful hand carved wooden lame.

Very sadly EJ is no longer with us. Recently a friend of EJ’s who is also a wood turner and carver offered to make these again for us in remembrance of our dear friend.

The Baking As Lifestyle Medicine (BALM) Protocol The Baking As Lifestyle Medicine (BALM) Protocol

The current food system is broken at multiple levels, from the pesticides used in our soils to the emulsifiers and additives adulterating industrially-processed foods. Nowhere is this more apparent than in the bread we eat.  The figures reported by the UK Flour Millers say that bread is bought by a staggering “99.8% of British households” and that “the equivalent of nearly 11 million loaves are sold each day. Approximately 60-70% of the bread we eat is white and sandwiches are thought to account for 50% of overall bread consumption. Average bread purchases are the equivalent of 60.3 loaves per person per year.” 

Most bread sold is made by modern processing methods that strip heart-healthy whole grains of their nutrient contents, resulting in low-fibre bread with a high glycemic index. Over time, white processed bread can increase a person’s risk of insulin resistance alongside other lifestyle diseases.

We’re on a mission to revolutionise the bread making process at every level – from soil to slice. The rules governing this are laid out in our Baking As Lifestyle Medicine protocol.
