Bread is like a taboo food to any person who is dealing with diabetes. However, what would happen to have a type of bread that fits your body rather than goes against it? Add sourdough a classic bread that is getting contemporary recognition due to its gut and blood sugar-friendliness.
Therefore, can sourdough bread be considered safe in diabetics? It is time to deconstruct the science, the benefits and what to seek in a really healthy loaf.
Why Sourdough Is Different from Regular Bread
In contrast to the commercial white or wheat bread, sourdough is produced by the process of natural fermentation in the presence of wild yeast and lactic acid bacteria. This becomes a slow fermentation which modifies the behavior of the carbohydrates in your body.
The result? A lower-calorie, less sugary, healthier bread, the three things diabetics are highly concerned about.

Glycemic Index: Why It Matters for Diabetics.
The glycemic index (GI) is used to determine the rate at which foods increase the level of sugar in the blood. High GI foods spike up very quickly, and this may be dangerous to diabetics.
It has been found out that low GI sourdough bread contains far less glycemic response than ordinary bread. With the fermentation process, the availability of simple sugars is decreased; glucose is slowed down in absorption. This is a stabilized energy, and reduced blood sugar panics.
That is one of the reasons why sourdough bread on diabetes is a smarter choice should it be consumed moderately.

Sourdough Bread Benefits Backed by Research
The following are science-supported sourdough bread advantages that render it to be diabetic friendly:
1.Improved blood sugar control
Lactic acid formed in the process of fermentation facilitates the retardation of the digestion of starch, which lowers postprandial glucose levels.
2.Better mineral absorption
The breakdown of phytic acid compounds through fermentation results in increasing mineral absorption of minerals such as magnesium and zinc- which are vital in metabolic health.
3.Longer satiety
Sourdough is more filling and helps to curb overeating and snacking.
Sourdough Bread for Gut Health
The gut health also has a surprisingly large role in the blood sugar regulation. The good gut microbiome enhances digestion and insulin sensitivity.
Sourdough bread is unique since it is naturally fermented, hence is good in gut health. The healthy microbes promote microbial diversity and contain gut inflammation which is usually attributed to insulin resistance.
This is where brands like Gutsee Foods truly shine.
Sourdough Bread Digestion: Easier on the Body
Nobody is immune to this challenge of bloating or weightiness after they have eaten bread. Due to fermentation, the digestion of sourdough bread is easier and light.
The bacteria partially digest gluten and complex carbs making sourdough easier to digest, including those with mild sensitivities.
