Bioavailability of Nutrients
Bioavailability is a crucial aspect of nutrition, referring to the extent to which our bodies can absorb and utilize the nutrients in the foods we eat. Fermentation can significantly enhance the bioavailability of certain nutrients, making them more accessible to our bodies. This is especially true for foods that are high in phytic acid, a compound that can inhibit nutrient absorption.
Production of New Bioactive Compounds
On top of enhancing nutrient bioavailability, fermentation can also produce new bioactive compounds that weren’t present in the original food. These compounds, such as organic acids and peptides, can have a range of beneficial effects on our health, from reducing inflammation to supporting gut health.
Production of these bioactive compounds is a complex process that involves the breakdown of carbohydrates by microorganisms. As these microorganisms feed on the sugars in the food, they release a range of compounds that can have a profound impact on our health. For example, lactic acid, a common byproduct of fermentation, has been shown to have anti-inflammatory properties.

Can Fermented Foods Improve Gut Health?
Not surprisingly, the answer is yes. Fermented foods have been shown to have a positive impact on gut health, which is crucial for overall well-being. A healthy gut microbiome plays a crucial role in digestion, immunity, and even mental health.
Reducing FODMAPs and Gluten
One of the ways fermented foods can improve gut health is by reducing or removing compounds that can cause gastrointestinal issues in some people. Fermentation can break down FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols), which can cause discomfort and bloating in individuals with irritable bowel syndrome (IBS). Additionally, fermentation can reduce or remove gluten from certain foods, making them more accessible to those with celiac disease.
Impact on Gut Microbiome
Impact of fermented foods on the gut microbiome is significant. The live bacteria present in fermented foods can become transient or even permanent members of the gut microbiota when consumed, bringing health benefits and helping to reduce the abundance of detrimental bacteria by competing against them.
It’s worth noting that even if the fermented food doesn’t contain live bacteria, it’s still associated with health benefits. The microbes produce health-promoting molecules, such as peptides, during the fermentation process, which can benefit your gut health. Furthermore, fermented foods can increase the concentration of beneficial bacteria in the bloodstream, activating receptors that inform the immune system and reducing inflammation.
Can Fermented Foods Boost the Immune System?
To understand how fermented foods can impact our immune system, it’s necessary to recognize that modern lifestyles may affect our immune system by altering the diversity of our microbes. Our diets are generally low in fiber, and we have a lot of antibiotics and stress, which can impoverish the microbes in our bodies.
Training the Immune System
Any imbalance in our gut microbiome can lead to a compromised immune system. Fermented foods, rich in live microbes, can help train your immune cells how to control inflammation, reducing the risk of developing auto-immune diseases.
Reducing Inflammation
Any amount of chronic inflammation can spread through the body, reaching the brain, heart, or liver, and cause chronic conditions. Fermented foods have been shown to reduce inflammation, which can lead to a healthier immune system.
It’s fascinating to note that fermented foods like sauerkraut have been found to increase the concentration of lactic acid bacteria in the bloodstream, activating a receptor called HCA3, which informs the immune system that foreign substances are in the body. This can lead to a less activated immune system, reducing the risk of auto-immune diseases. By consuming fermented foods, you may be able to train your immune system to better differentiate between good and bad bugs, leading to a stronger and more resilient immune system.
Can Fermented Foods Help with Anxiety and Depression?
Once again, the answer lies in the complex relationship between your gut microbiome and overall health. Fermented foods, with their rich supply of beneficial microbes and bioactive compounds, may play a role in supporting mental wellbeing.
