Sourdough relies on a mix of wild yeast and lactic acid bacteria, rather than baker's yeast, to leaven the dough. It's richer in nutrients, less likely to spike your blood sugar, contains lower amounts of gluten, and is generally easier to digest than bread made with baker's yeast.

Whole grain and rye flours provide minerals and enzymes that can influence acid production in sourdoughs. The higher mineral content of whole grains acts as a buffer in the dough so that more acid can be produced during extended fermentation.

There is no single best ratio, but I've found a ratio of 1:5:5 fed twice daily at 12-hour intervals to produce a sourdough starter that's strong and healthy. This ratio corresponds to 20% ripe starter carryover, 100% water, and 100% flour (a mix of whole grain rye and white flour) at each feeding.

Sourdough bread may be easier to digest than white bread for some people. According to some studies, sourdough bread acts as a prebiotic, which means that the fiber in the bread helps feed the “good” bacteria in your intestines. These bacteria are important for maintaining a stable, healthy digestive system.

Whole wheat sourdough bread is one of the healthiest types of sourdough breads. Any sourdough bread with whole grains is considered healthier to classic sourdough bread.

May support gut health

Although the beneficial microbes in the starter tend to be lost during the baking process, the fibre and plant compounds, called polyphenols, become more bio-available. These act as an important fuel source for our gut microbes, which explains why sourdough is a gut-friendly choice.

One consequence of the common belief that sourdough should be sour is that commercial sourdough is too sour. Sadly, most commercial sourdoughs aren't actually sourdough breads. They are yeasted breads that have had acetic acid, malic acid, and/or fumaric acid added to them.

The yeasts cause the dough to rise by creating carbon dioxide bubbles, while the lactic acid bacteria provide the sour flavor (in the form of acetic acid and lactic acid) and preserve the bread by lowering its pH, which prevents the growth of food borne pathogens.

Ferment Your Sourdough For A Shorter Time

One of the easiest ways to manipulate the sourness of your sourdough bread is simply to decrease the time that it ferments for. There a few ways that you can do this and often you will need to experiment to find what works best for you.

What is the healthiest flour for sourdough bread? ›

Compared to whole wheat flour, rye flour is said to be the most nutrient- and amylase-dense option for a sourdough starter. Overall, it has a lower gluten protein content than wheat flour, which means it produces slack, sticky, and dense doughs.

If you don't get rid of the excess, eventually you'll have more starter than your feedings can sustain. After a few days, your daily 1/4 cup flour and water won't be enough to sustain your entire jar of starter, and your starter will be slow and sluggish, not much better than discard itself.

In 2020, Seamus Blackley, the creator of Xbox and a seasoned baker himself, baked sourdough bread from dormant yeast samples that are 4,500 years old, according to the Atlas Obscura website.

The best bread to reduce gut inflammation is bread made from whole grains. Refined grains, such as the grains found in white bread and white pasta, are known to increase inflammation across the whole body. Sourdough bread and rye bread are both good options for an anti-inflammatory diet.

Although baked sourdough bread may not contain probiotics since they are likely not able to survive the high heat of the baking process, it does still contain prebiotics, which are also vital for proper digestion and gut health.

The best part about using leftover sourdough discard in your baking and cooking? You get the added benefit of fermented grains – making it easier to digest and better absorbed by the body.

The development of lactic acid in sourdough starter creates more antioxidants in this type of bread than in other kinds. It may also make some minerals more available for digestion than they are in ordinary bread by breaking down phytates which keep your body from accessing all the minerals in ordinary bread.

Consumption of sourdough bread reduces postprandial blood glucose and insulin response. This mechanism could explain why organic acids, such as lactic and acetic acids, produced in sourdough lower its estimated glycemic index (eGI).

Sourdough is naturally leavened bread, which means it doesn't use commercial yeast to rise. Instead, it uses a 'starter' – a fermented flour and water mixture that contains wild yeast and good bacteria – to rise. This also produces the tangy flavour and slightly chewy texture you'll find in sourdough.
