Common Mistakes And Misconceptions

Mistake/Misconception Correct Viewpoint
Gut microbiota has no effect on mental resilience. Research has shown that the gut microbiota can influence brain function and behavior, including mood and stress response, which are important components of mental resilience.
Mental resilience is solely determined by genetics or upbringing. While genetics and upbringing may play a role in determining an individual‘s level of mental resilience, research suggests that environmental factors such as diet and lifestyle choices can also have a significant impact on this trait. The gut microbiota is one such factor that can affect mental resilience through its influence on brain function and behavior.
All probiotics are equally effective in improving mental health outcomes. Not all probiotics are created equal when it comes to their effects on the gut microbiota and subsequent impacts on mental health outcomes like stress reduction or improved mood regulation. Different strains of bacteria have different functions within the gut ecosystem, so it’s important to choose a probiotic supplement with specific strains known to support healthy brain-gut communication for optimal results.
A single intervention (e.g., taking a probiotic) will be enough to improve overall mental resilience. While interventions like taking certain types of probiotics may help improve aspects of your gut-brain axis functioning over time, they’re unlikely to be sufficient alone for building long-term psychological resiliency without other supportive practices like regular exercise or mindfulness meditation practice.
Only people with diagnosed digestive disorders need worry about their gut health impacting their emotional well-being. Even if you don’t experience any overt digestive symptoms or conditions, there’s still evidence suggesting that optimizing your microbial balance through dietary changes or targeted supplementation could benefit your overall emotional well-being by supporting better communication between your enteric nervous system (ENS) – aka "the second brain" -and central nervous system (CNS). This means anyone interested in boosting their psychological resiliency could benefit from taking steps to support their gut health.
