Probiotics for mental health: what science says about the gut–brain connection
“There are animal studies On this subject, “explains Stengel,” and growing indications based on evidence that certain probiotic bacterial strains called psychobiotics can have a positive influence on mood, stress and anxiety. »»
Certain strains of lactobacilli and bifidobacterium are distinguished. Studies have shown that they reduce anxiety behavior in animals, reduce stress in healthy test subjects and lead to better sleep. “In patients with irritable colon syndrome, probiotics with bifidobacteria were even able to alleviate anxiety symptoms,” said Stengel.
These results show that probiotics, when used in a targeted way, also influence emotional balance. However, it is important to note that the underlying mechanism is not yet fully understood. According to Stengel, it is assumed that the effect is obtained via the modulation of inflammatory processes, nerve activity and the regulation of stress hormones such as cortisol and neurotransmitters such as serotonin and dopamine, which occur along the Gut brain axis. Of course, these results are mainly based on studies within specific groups and cannot therefore be generalized without further study.
A diet for a better mood
Each day, life also plays an important role in the health of the microbiome and our mental state. “A healthy diet is, of course, good for a healthy body,” says Stengel.
This does not mean that every “well-being” trend will work for everyone. Intermittent fasting, for example, may not be adapted to people with pre -existing conditions or irritable colon syndrome.
To this end, it is important to adopt a balanced, individualized and holistic approach. Prioritize the basics of sleep well-being, hydration, nutrition and adequate movement: “It is important for everyone to drink enough liquids every day and eat with conscience colorful, fresh and rich fiber meals in a calm and relaxed atmosphere,” says Stengel. “Fermented foods, sufficient exercise and daily relaxation also play an essential role.”
In other words, probiotics can be part of a complete program, but it is important to also take into account all aspects of health. “Yes, I see it that way,” says Stengel. “The only question is whether we really have to buy probiotics at the pharmacy or if our microbiome can also be cultivated healthy thanks to an appropriate pre-probotic diet,” she says. “Anyway, the intestinal microbiome can influence our body both negatively and positively.”
