• EXPLORE FURTHER: The THREE lesser-known indications that your digestive system may be unhealthy

Healthy bacteria in your gut could be the key to tackling stress, a study suggests.

Researchers in California examined over 100 individuals who did not have mental health issues and carried out surveys related to their psychological well-being and resilience.

The participants were subsequently split into two categories based on their resilience levels: high and low. Additionally, each individual had an MRI scan performed and submitted fecal samples for analysis.

The team discovered that the highly resilient group exhibited reduced levels of inflammation and showed better outcomes. stronger gut barrier Stronger barriers are crucial for effectively absorbing nutrients and preventing toxins from entering the gut compared to those with lesser resilience. A robust barrier is vital for both nutrient absorption and toxin blockage within the gut.

They did not consider patients who have mental health issues.

The connection relies on the immediate exchange between the brain and the digestive tract. For instance, this involves the gut transmitting feelings of hunger or fullness to the brain.

The researchers indicated that these discoveries might result in therapies utilizing gut bacteria to tailor mental healthcare approaches.

Dr. Arpana Gupta, the lead researcher and co-director of the UCLA Goodman-Luskin Microbiome Center, stated: "By identifying the characteristics of a robust and resilient brain along with a healthy microbiome, we can create specific interventions aimed at these aspects to decrease stress levels."

The UCLA group assessed 116 adults who hadn't received a diagnosis of a mental health disorder.

About 61 percent of participants were female, while the remainder were male.

Most of the participants in each group were Caucasian, with Asian adults being the next largest demographic. The mean Body Mass Index (BMI) stood at approximately 28, placing them within the category of overweight.

Each participant had MRI scans conducted and submitted stool samples using home collection kits two to three days prior to the test.

The week before, they completed comprehensive surveys regarding their eating habits.

In a survey where individuals reported their own responses, participants addressed queries related to their resilience using a scale ranging from zero (not true at all) to four (true almost always).

The overall score was comprised of seven elements: individual resilience; setting high standards with perseverance; trusting gut feelings; enduring adverse consequences and stress; embracing changes and fostering connections; exercising self-control; and spiritual impact.

Greater points indicated enhanced resilience, suggesting they could cope with pressure more effectively and bounce back from challenges better.

The study revealed that individuals with higher resilience experienced lower levels of anxiety and depression, were less susceptible to criticism, and demonstrated greater skill in managing their emotional responses compared to those with lesser resilience.

Moreover, this particular group exhibited more robust microbiomes. These microbial networks consist of bacteria, parasites, and fungi that play crucial roles in maintaining the health of the digestive, immune, hormonal, and nervous systems.

The researchers indicated that these participants expelled substances associated with reduced inflammation and enhanced intestinal barriers when contrasted with individuals exhibiting lesser resilience.

This research contributes to the growing body of recent studies exploring the gut-brain axis, affecting aspects such as appetite, fullness, food desires, digestive processes, metabolic rates, stress levels, and immune function, as stated by the Cleveland Clinic.

"Resilience genuinely encompasses the entire body, impacting not just your brain but also your microbiome and the metabolites it produces," Dr. Gupta stated.

Dr. Desiree Delgadillo, the lead author and a postdoctoral researcher at UCLA, commented: "Within our gut lies an entire microbial ecosystem with healing qualities and bioactive compounds, and I'm excited to expand on this work."

Several constraints were acknowledged nonetheless. The investigators highlighted that subsequent investigations ought to incorporate subjects suffering from mental health issues such as depression and PTSD. Additionally, further studies are required to validate these conclusions overall.

The research was released last week in Nature Mental Health .
