Healthy Bread: Evaluating Your Loaf’s Nutritional Value

Is your bread healthy? Try The Bread Health Calculator

Don’t Be Fooled: Discover If Your Bread is Really Healthy

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, 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.

Bread Health Scoring Form

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.

All reasonable care is taken when writing about health aspects of bread, but the information it contains is not intended to take the place of treatment by a qualified medical practitioner. You must seek professional advice if you are in any doubt about any medical condition.

    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.

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 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.
