Why Should Bodybuilders Consider Sinless Sourdough?

Sinless Sourdough isn’t just another trendy food item; it’s a nutritional powerhouse that can support your bodybuilding goals in multiple ways.

Let’s dive into why this low-carb sourdough bread deserves a place in your meal plan:

1. Proteolysis during Fermentation:

The primary way sourdough fermentation improves protein digestibility is through the action of proteolysis, the breakdown of proteins into smaller peptides and amino acids. During fermentation, wild yeasts (such as Saccharomyces cerevisiae) and lactic acid bacteria (LAB) secrete enzymes that break down the proteins in the flour, particularly glutenand other storage proteins.

Proteases: Both yeast and LAB produce proteases, enzymes that cleave the long chains of proteins into shorter chains called peptides or even individual amino acids. These smaller molecules are much easier for the human digestive system to absorb than the larger, intact proteins.
Gluten Breakdown: In wheat-based sourdough, gluten is the major protein. Gluten is a relatively complex protein, and it can be difficult to digest for some individuals. Sourdough fermentation partially breaks down gluten into smaller peptides, reducing its size and making it less likely to cause digestive discomfort.
- Gluten Hydrolysis: Studies have shown that during sourdough fermentation, gluten is hydrolyzed (broken down by water and enzymatic action), which reduces its molecular weight and makes it easier for digestive enzymes to further break it down in the stomach and intestines.

2. Microbial Contribution to Protein Breakdown:

Lactic Acid Bacteria (LAB): LAB, which are naturally present in the fermentation process, produce lactic acidand also secrete proteolytic enzymes that assist in breaking down proteins in the dough. The LAB species involved (like Lactobacillus and Leuconostoc) have been shown to produce enzymes such as peptidases and proteinases, which further degrade proteins into simpler forms that are easier to digest.
Yeast Contribution: Yeasts like Saccharomyces cerevisiae also contribute to protein breakdown by secreting proteolytic enzymes. These enzymes act on proteins to reduce their complexity and improve digestibility.

3. Reduction in Anti-Nutrients:

Phytic Acid Degradation: During sourdough fermentation, phytic acid (an anti-nutrient) is broken down by both microbial enzymes and the natural phytase enzymes present in the flour. Phytic acid normally binds to proteins and minerals, which can make digestion and absorption of these nutrients more difficult.
By reducing the levels of phytic acid, fermentation helps release proteins and other nutrients, making them more accessible for digestion and absorption.

4. Acidic Environment and Enzyme Activation:

The acidic environment created during fermentation (primarily due to the production of lactic acid) helps activate certain endogenous enzymes in the flour, such as phytase, which break down phytic acid, as well as enzymes like proteases that help further degrade proteins.
The lower pH (around 4-5) in the sourdough bread dough also denatures (unfolds) proteins, making them more accessible for digestive enzymes to act on them. This denaturation process can enhance the efficiency with which digestive enzymes like pepsin (in the stomach) and trypsin (in the small intestine) break down proteins.

5. Reduction of Protein Complexity:

By breaking down proteins into smaller peptides and amino acids during fermentation, sourdough bread becomes easier to digest. The digestive system can absorb these smaller molecules more efficiently than larger, intact proteins.
Gluten: In non-fermented bread, gluten can be difficult for some individuals to digest, and in certain cases, it can cause digestive discomfort or sensitivities. However, sourdough fermentation has been shown to partially hydrolyze gluten, making it more digestible and potentially less allergenic or irritating for some people.

6. Beneficial Impact on Gut Health:

Gut Microbiome: The fermentation process also introduces beneficial bacteria (lactic acid bacteria) to the gut. These bacteria can have a positive impact on gut health by promoting a healthy balance of gut microbiota, which can aid in the digestion and absorption of proteins and other nutrients.
Improved gut health can enhance the overall digestive efficiency, which can aid in protein digestion and absorption.

Does Sinless Sourdough Affect Gut Health and Your Microbiome?

A mouse feeding study conducted by researchers and published in Frontiers in Microbiology in September 2022 compared the effects of white bread containing 40% sourdough (WBS) to yeast-leavened white bread (WB) on mice.

The researchers found that sourdough had several beneficial effects compared to yeast-leavened white bread.

Reduced the glycemic index, suggesting potential diabetes-lowering effects:

Sourdough bread typically has a lower glycemic index than regular bread, meaning it causes a slower and more moderate rise in blood sugar levels. This is due to several factors in the sourdough-making process. The long fermentation breaks down some starches and sugars, making them easier for your body to process. The increased acidity from fermentation slows down how quickly carbohydrates turn into glucose in your blood. Sourdough also contains more resistant starch, which acts like fiber and further slows digestion. The fermentation process changes the bread’s structure in ways that affect digestion speed. Additionally, sourdough’s lower pH may slow down how quickly your stomach empties. All these factors work together to create a bread that’s generally easier on your blood sugar levels than regular bread.

Keep in mind that while the sourdough fermentation process reduces carbs by about 30%, traditional sourdough is still high in carbs, well above the carbs we can enjoy on a low carb diet. That’s what makes Sinless Sourdough so special. It has all the health benefits of traditional sourdough, but without the high carbs.

Better Magnesium Absorption:

Better magnesium absorption due to phytate degradation during fermentation. Fermentation, which happens when making sourdough bread, breaks down something called phytates. Phytates are compounds in grains that can make it harder for our bodies to absorb certain minerals, like magnesium.When the phytates are broken down during fermentation, it becomes easier for our bodies to absorb magnesium from the bread. This means that sourdough bread might provide more magnesium to our bodies compared to regular bread.In other words, the fermentation process makes the magnesium in the bread.

Decreased Total Cholesterol and Triglycerides:

Sourdough bread’s effect on cholesterol and triglycerides is not fully clear. Some studies show it can lower total and LDL cholesterol, especially when made with whole wheat. However, other research finds no significant difference compared to regular bread. The impact may depend on a person’s genetics and the type of flour used. While sourdough might help some people lower their cholesterol, it doesn’t work the same for everyone. More research is needed to understand exactly how and why sourdough affects blood fats in different people.

Showed Anti-Inflammatory Properties:

Studies show anti-inflammatory properties by decreasing pro-inflammatory cytokines TNF-α and IL-6.Sourdough bread may have anti-inflammatory properties, but the exact way it affects specific inflammatory markers like TNF-α and IL-6 isn’t fully clear. Studies show that sourdough fermentation can improve the antioxidant and anti-inflammatory qualities of bread, especially when using certain types of wheat. The fermentation process creates bioactive compounds that can help protect against inflammation in the gut. Some research suggests that sourdough bread might make people feel better digestively, which could be related to reduced inflammation. The beneficial bacteria in sourdough also increase the availability of nutrients and antioxidants in the bread, which might help fight inflammation overall. However, more specific research is needed to understand exactly how sourdough bread might lower TNF-α and IL-6 levels in the body.

Increased Beneficial Gut Bacteria:

Sourdough bread can help increase beneficial gut bacteria like Akkermansia, Bifidobacterium, and Lactobacillus in several ways. It acts as a prebiotic, feeding these good bacteria with its fiber content. The fermentation process used to make sourdough produces compounds that encourage the growth of these helpful bacteria. Sourdough also contains more resistant starch, which acts like fiber and further supports gut bacteria. The bread’s increased acidity and fermentation process make nutrients more available and reduce substances that can hinder nutrient absorption, creating a better environment for beneficial bacteria to thrive. While a mouse study has shown promising results, more research is needed to fully understand how sourdough affects human gut bacteria, as effects may vary based on the bread-making process and individual gut compositions.

The study concluded that sourdough bread consumption led to positive changes in glucose metabolism, mineral absorption, cholesterol levels, inflammatory markers, and gut microbiota composition in mice. It’s important to note that this was an animal study, and further research is needed to confirm these effects in humans. Human studies are still needed to confirm sourdough’s specific impacts on the gut microbiome.

This is what we do know:

Sourdough fermentation process produces beneficial compounds:

The long fermentation creates lactic acid, which can increase bioavailability of nutrients and break down gluten proteins.
It produces organic acids and enzymes that improve mineral absorption.
It forms resistant starch that acts more like fiber.

Potential prebiotic effects:

The non-digestible fibers in sourdough may help feed beneficial gut bacteria.
This could potentially increase microbial diversity in the gut.

Improved digestibility:

The fermentation process breaks down gluten and other compounds, potentially making it easier to digest for some people.
May be better tolerated by those with non-celiac gluten sensitivity (though not safe for celiac disease).

Probiotic content:

The live cultures in the sourdough starter are killed during baking, so sourdough bread itself is not a probiotic food.
However, eating it with other fermented foods could provide probiotic benefits.

Microbiome impacts:

There’s limited evidence on how sourdough directly affects the gut microbiome composition.
More research is needed on its specific effects compared to regular bread.

Other potential benefits:

Lower glycemic index
Increased free amino acids and protein digestibility
Antioxidants and nutrients like selenium

How Does Sinless Sourdough Improve Mineral Absorption?

The fermentation process in sourdough bread production is a key factor in improving mineral absorption. This process takes place also in Sinless Sourdough. Let’s break down how this works for three essential minerals: zinc, magnesium, and copper.

Zinc Absorption: Zinc is a critical mineral for bodybuilders. It plays a vital role in protein synthesis, muscle growth, and maintaining healthy testosterone levels. The sourdough fermentation process reduces phytic acid, which can bind to zinc and prevent its absorption. By eating Sinless Sourdough, you’re potentially increasing your body’s ability to absorb and utilize zinc from your diet.
Magnesium Absorption: Magnesium is involved in over 300 enzymatic reactions in the body, including energy production and muscle function. It’s also crucial for regulating cortisol levels, which can impact muscle gains. The fermentation process in Sinless Sourdough can increase magnesium bioavailability, helping ensure your body gets the magnesium it needs for optimal performance and recovery.
Copper Absorption: While often overlooked, copper is an essential mineral for bodybuilders. It works synergistically with zinc and iron for proper absorption and supports connective tissue health.
