Is white bread healthy?

Looking after your family

If you are reading this, it means you have started asking the right questions – because not all bread is created equally. More then ever industrial bread manufacturers are showing all their resources at trying to convince you that white bread ( including white sourdough,) is good for you.  In most cases it is just less bad for you. 

To give you some insight into white bread and health you can listen to Tim Spector in this video, (who is one of the worlds leading experts in gut health) chatting with me, Vanessa Kimbell about bread. You can also learn more about bread in this podcast and also check out Zoe and the work Tim and the team does.

But I’ve always eaten white Bread 

If you have grown up just eating white bread, then this will be the kind of bread that seems normal to you – but when you take a closer look and ask whether white bread is healthy, you are considering the long-term health implication of feeding white bread to your family. My hope is that when you read this, you might change your mind about feeding it to the people you love.

Why White Bread is bad for your mood

Let’s start with a simple fact –  most refined white bread is absorbed by the body fast, so it raises your blood sugar. Your body uses insulin to take the sugar out of your blood, and this in turn can lead to low blood sugar. At this point, a stress hormone called cortisol can kick in. It’s terrible for mood and concentration and for managing hunger levels.

How White bread starves your microbes of essential fibre

We’re really only just beginning to understand that your gut microbiome is the centre of your immune system. What we do know is the significance of fibre. Fibre is central to your gut working correctly and so we don’t recommend making or buying bread with 100% refined white flour.  The processing white roller milled flour goes through means it is devoid of fibre and stripped of the nutrients that nourish the gut. What is more, a diet high in refined carbohydrates such as white bread is associated with non-communicable diseases, including diabetes, obesity and bowel cancer.

Can you make white bread healthier?

Yes, you can make white bread healthier. Using stoneground white flour is an improvement: it is healthier, as it contains more fibre and vitamin E. At the Sourdough School and the Sourdough Club, we never make 100% white bread. Although we still use organic white flour, we blend it with wholegrain and other flours and our Botanical Blends to increase diversity in our bakes. Having diversity in the grains you eat is good for your microbiome, providing it with more fibre and more variety.

Sourdough is a healthier way to make bread

Another thing to consider is the method of production of your white bread, especially if you buy it. If you do want to eat white bread, we recommend you use stoneground white flour and make your own white sourdough bread, because this will be healthier than white yeasted bread (meaning a loaf containing commercial yeast).

This is because sourdough bread does not include potentially gut damaging emulsifiers, goes through a long, slow fermentation process, which makes it more nutritious than a yeasted loaf. The fermentation process in sourdough reduces the gluten load, meaning sourdough bread can be digested more easily, and it also increases resistant starch, which is responsible for controlling blood sugar.

Live longer

Regular consumption of wholegrain foods has been associated with a reduction in both cardiovascular disease and diabetes, reductions in cancer mortality at certain sites, and an overall reduction in premature death. It is interesting, too, to learn that children who consume whole grains have significantly higher intakes of fibre and magnesium compared to children who do not.

Slowly does it – our advice on how to move away from yeasted white bread

If you’ve always eaten white bread, then it’s worth increasing the percentage of wholegrain you eat slowly, so your body has time to get used to – otherwise,  you can end up with bloating and wind. At the Sourdough Club, we teach our members to introduce wholegrain flour to their bakes slowly, as they work their way through the lessons. This is a great approach, because you gradually get used to baking with wholegrain flour, while your body gets used to eating it – and it’s much better for you and your whole family than white industrial bread.

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.

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.
