Probiotics are live microorganisms that provide numerous health benefits when consumed in adequate amounts. They are commonly found in fermented foods like yogurt, kefir, kimchi, and sauerkraut, among others. While most people think of probiotics as primarily improving gut health, there is growing research that suggests that they can also impact mental health.
Surprising Benefits of Probiotics for Mental Health
Below are seven surprising benefits of probiotics for mental health:
1. Reduced Anxiety
Anxiety disorders are the most common mental health disorders in the world. Recent research suggests that consuming probiotics may help alleviate symptoms of anxiety. A study conducted in 2017 found that participants who consumed probiotics for four weeks reported lower levels of anxiety compared to those who did not consume probiotics.
2. Improved Mood
Consuming probiotics may also help improve mood. A study conducted in 2016 found that participants who consumed probiotics for four weeks reported lower levels of perceived stress and sadness. Another study conducted in 2018 found that participants who consumed probiotics for four weeks reported improved general mood.
3. Better Cognitive Function
Cognitive function refers to the ability to learn, remember, process, and use information. Recent research suggests that consuming probiotics may help improve cognitive function. A study conducted in 2016 found that participants who consumed probiotics for 12 weeks reported improved cognitive function compared to those who did not consume probiotics.
4. Reduced Symptoms of Depression
Depression is a common and serious mental health disorder that affects millions of people worldwide. Recent research suggests that consuming probiotics may help reduce symptoms of depression. A study conducted in 2017 found that participants who consumed probiotics for eight weeks reported reduced symptoms of depression compared to those who did not consume probiotics.
5. Increased Resilience to Stress
Stress is a common and often unavoidable part of everyday life. However, prolonged or chronic stress can have negative impacts on mental health. Recent research suggests that consuming probiotics may help increase resilience to stress. A study conducted in 2014 found that participants who consumed probiotics for three weeks reported reduced levels of the stress hormone cortisol compared to those who did not consume probiotics.
6. Improved Sleep
Sleep is critical for overall health and wellbeing, including mental health. Recent research suggests that consuming probiotics may help improve sleep. A study conducted in 2017 found that participants who consumed probiotics for eight weeks reported improved sleep quality compared to those who did not consume probiotics.
7. Reduced Symptoms of Autism
Autism is a complex developmental disorder that affects communication, social interaction, and behavior. Recent research suggests that consuming probiotics may help reduce symptoms of autism. A study conducted in 2017 found that children with autism who consumed probiotics for four months reported improved social cognition compared to those who did not consume probiotics.
Conclusion
The benefits of probiotics for gut health are widely known, but their potential impact on mental health is still being explored. While more research is needed to fully understand the mechanisms behind these benefits, the existing evidence suggests that consuming probiotics may be a simple and effective way to support mental health and wellbeing.
