Signaling Mechanisms of Postbiotics

Postbiotics communicate with our bodies through a fascinating system.

At the microscopic level, microbial products called MAMPs from good bacteria interact with special receptors on our cells, named PRRs.

Key players in this game include MAMPs like teichoic acids and cell wall proteins, and PRRs such as Toll-Like Receptors and G-Protein-Coupled Receptors ¹.

This crucial conversation sparks our immune system into action, offering health boosts like reducing inflammation and even showing potential against cancer².

The details of how postbiotics work aren’t fully clear yet.

But we know, for instance, that some postbiotics can block inflammation in our gut, acting as peacekeepers when things go awry ³.

Others seem to fine-tune our immune response, promoting certain helpful compounds while suppressing harmful ones.

Notably, a molecule called Polysaccharide A can manage inflammation, acting almost like a traffic cop for our immune reactions⁴.

Interestingly, even bacteria that aren’t alive can affect our immune responses⁵.

For the elderly, balancing gut health with postbiotics might even enhance the effectiveness of vaccinations, though more studies are needed⁶.

Beyond the immune system, postbiotics show promise in fighting cancer by blocking harmful processes and even stalling cancer growth ⁷.

They might also guard our hearts by influencing cholesterol levels, as seen with certain Lactobacillus bacteria ⁸.

To truly harness postbiotics’ potential, we must dive deeper, employing advanced tools to untangle these intricate interactions ⁹.

Health and nutritional benefits of postbiotics

While many know the health perks of prebiotics and probiotics, research reveals that postbiotics may be the unsung heroes.

These are beneficial compounds created during food fermentation.

The exact makeup of postbiotics varies based on how they’re made.

They play a role in numerous bodily functions and offer health advantages throughout life.

As research expands, so does our understanding of postbiotics.

However, it’s crucial to exercise caution, as some people might experience adverse effects after consumption.

Postbiotics in Food Safety and Preservation

Postbiotics are revolutionizing the way we perceive food safety and quality. These microbial byproducts are showcasing their prowess in a multitude of non-clinical applications.

1. Food Preservation and Enhancement

Biopreservation: The key here is extending food shelf life and safety. Postbiotics can fight against spoilage and harmful pathogens.

For example, postbiotics from certain strains have been shown to reduce harmful bacteria in chicken¹⁰ and enhance the safety of vacuum-packaged sausages ¹¹.

Moreover, they can protect dairy products and fruits, often better than traditional preservatives, by neutralizing harmful bacteria ¹².

Functional Foods: The incorporation of postbiotics can enhance the health benefits of our daily food.

A case in point: milk fortified with postbiotics derived from specific strains reduces allergic reactions in young children ¹³.

Food Packaging: To further maximize shelf life, postbiotic active packaging can be employed. This involves embedding postbiotics into packaging materials to prevent microbial deterioration.

Notably, organic acids like lactic and citric acid disrupt pathogen growth, while peptides and bacteriocins block microbial growth through various mechanisms¹⁴.

2. Sensory Experience of Postbiotic-Enriched Foods

While postbiotics enhance food safety, they might alter sensory experiences.

Recent studies, like one involving yogurt with Cape Gooseberry postbiotics

¹⁵ and another with lamb meat slices¹⁶, showed positive sensory feedback, with some minor caveats.

Generally, postbiotics can be used without significantly altering the taste, texture, or appearance of foods.

3. Combatting Biofilms

A significant challenge in the food industry is the biofilms created by bacteria. These microbial defenses are notorious for their resilience against cleaning efforts.

However, postbiotics emerge as potential biofilm busters.

A study involving specific strains highlighted their ability to diminish biofilms formed by notorious bacteria like L. monocytogenes ¹⁷.

In conclusion, postbiotics are showcasing their versatility and potential in non-clinical applications, especially in the food industry.

Their role in food preservation, enhancing food quality, and battling biofilms position them as promising allies for food technologists and scientists.

Postbiotics: A Game-Changer in Skincare

Human skin, our frontline defender, can suffer microbial imbalances leading to acne issues.

Research reveals that topical probiotics can combat acne-inducing bacteria, such as C. acnes and S. epidermidis ¹⁸.

Noteworthy is a lotion containing bacteriocin from E. faecalis SL-5, which lessens acne inflammation.

Similarly, LactoSporin, a peptide from Bacillus coagulans, is gaining attention for its potent topical benefits, especially under acidic conditions¹⁹.

Boosting Performance: The Role of Postbiotics

New research points to “biological doping” through postbiotics. Studies show that the intestinal Veillonella species transforms lactic acid into propionate, enhancing mice’s physical endurance.

When given propionate, mice exhibited longer run-to-exhaustion times, underscoring its potential to improve athletic performance ²⁰.

The Future of Postbiotics: From Precision Medicine to Disease Prevention

Research has spotlighted postbiotics as a safer alternative to probiotics.

Their health benefits are similar, yet they avoid the risks of live microbes, offering a safer option for vulnerable groups like preterm infants ²¹.

Notably, postbiotics show potential in addressing daunting diseases like Alzheimer’s and multiple sclerosis.

Precision postbiotics

The future vision for postbiotics includes “precision postbiotics”.

Just as precision medicine tailors treatments to individual patients, precision postbiotics would cater to specific illnesses in patient subgroups²².

Nanotechnology

A parallel advancement is nanotechnology’s integration into nutraceuticals, enhancing the bioavailability of key components for improved therapeutic outcomes.

Nanotechnology could be a game-changer for delivering postbiotics, using nanoparticles to actively target systems for controlled delivery.

Though promising, this approach still requires extensive research and rigorous clinical trials²³.

Biomarkers for viral infections

In the realm of infectious diseases, postbiotics are emerging as potential biomarkers for viral infections, including coronavirus.

The metabolic activity of postbiotics might predict viral diseases, offering a strategy to manage pandemics like COVID-19.

Certain postbiotics, like those from Lactobacillus plantarum Probio-88, might even help contain the spread of potent viruses ²⁴.

Yet, despite the optimism, challenges remain.

The intricate workings of postbiotics aren’t fully understood, and more research is needed to substantiate their health claims.

But as research advances, postbiotics stand at the convergence of food science, microbiology, health, and individualized therapy, promising innovative solutions for future health challenges.

Discussion
