You’ve probably heard people say that sourdough bread is healthier than normal bread.
But is it actually true?
Since I started making my own sourdough bread, one of the things that surprised me most was just how simple the ingredients are.
A basic sourdough loaf needs only:
Flour
Water
Sourdough starter
Salt
That’s it.
And because your starter itself is simply flour and water that has been naturally fermented, homemade sourdough can be one of the simplest breads you can make.
So, What Makes Sourdough Different?
The big difference isn't necessarily the flour.
It's fermentation.
Instead of relying only on commercial baker's yeast to make the bread rise quickly, traditional sourdough uses a living starter containing naturally occurring yeasts and lactic-acid bacteria.
The dough is then given time to ferment.
And that extra time changes the bread.
Is Sourdough Healthier?
It can be, particularly when you're comparing traditionally fermented sourdough with highly processed white bread.
Research suggests that sourdough fermentation may improve the availability of certain minerals by reducing phytates in the dough.
Some sourdough breads may also produce a lower blood-glucose response than comparable breads, although this depends on the flour, fermentation method, recipe and the individual eating it.
Fermentation can also make sourdough easier for some people to digest.
But there's something important we shouldn't ignore:
Sourdough is still bread.
It still contains carbohydrates and calories, and simply putting the word sourdough on a loaf doesn't automatically make it healthy.
A wholegrain sourdough, for example, will generally provide more fibre than a sourdough loaf made entirely from refined white flour.
Homemade vs Shop-Bought
This is where I really started appreciating homemade bread.
When I make sourdough at home, I know exactly what went into it.
There isn't a mysterious ingredient list to decipher.
Flour. Water. Starter. Salt.
Commercial breads can vary enormously. Some are also made from very simple ingredients, while others contain added sugar, oils, preservatives, emulsifiers or other ingredients needed for flavour, texture and shelf life.
So rather than assuming every shop-bought loaf is unhealthy, turn the packet over and read the ingredient list.
You might be surprised by what you find.
What About the Sourdough You Buy at the Supermarket?
Here's another interesting one.
Not every loaf labelled "sourdough" has been made using the same traditional long-fermentation process.
Some commercially produced sourdough-style breads may use baker's yeast, sourdough flavourings or shortened production methods.
If you're buying sourdough because you specifically want traditionally fermented bread, check the ingredients and, where possible, find out how the loaf was made.
My Favourite Part About Making Sourdough
For me, sourdough isn't only about whether one slice is technically healthier than another.
It's about learning how food is made.
You take flour and water, look after a starter, mix a dough, wait for fermentation to do its work and eventually pull a beautiful loaf of bread out of the oven or air fryer.
There's something incredibly satisfying about that.
And once you've made bread yourself, you start looking at that supermarket bread aisle a little differently.
Let's Talk
Do you normally buy white, brown, wholewheat or sourdough bread?
Have you ever checked the ingredient list on the bread you normally buy?
Would you try making sourdough if you knew you only needed four basic ingredients?
Have you ever tasted homemade sourdough?
Do you think knowing exactly what's in your food changes the way you eat?

This Week's Challenge
Next time you buy bread, turn the packet around and read the entire ingredient list.
Don't judge the ingredients immediately.
Just see what's actually in the bread you've been eating.
Then compare that list with homemade sourdough:
Flour + Water + Starter + Salt

If you've tried making sourdough, tell us about it.
Was your first loaf beautiful?
Did it come out flat?
Did your starter refuse to cooperate?
Or did you become completely obsessed with sourdough once you started?
