When it comes to dealing with stress, we are often told that the best thing we can do is exercise, make time for activities we love, or try meditation or mindfulness.
However, according to research published by me and other members, the type of food we eat may also be an effective way to deal with stress. APC Microbiome IrelandOur latest study showed that eating more fermented foods and fiber daily for just four weeks had a significant effect on weight loss. perceived stress level.
in the last 10 yearsa growing body of research shows that a diet can have have a huge impact on our mental healthIn fact, a healthy diet may even reduce risk many common mental illnesses.
The mechanisms underpinning dietary effects on mental health are not yet fully understood. But his one explanation for this connection may be due to the relationship between our brains and the microbiome — the trillions of bacteria that live in our gut.
Known as the gut-brain axis, this axis allows the brain and gut to be in constant communication with each other, enabling important bodily functions such as digestion and appetite. It also means that the emotional and cognitive centers of our brain are closely connected to the gut.
Previous studies have shown that stress and behavior also Linked to our Microbiomeit was previously unknown whether changes in diet (and thus our microbiome) have a distinct effect on stress levels.
This is what our research seeks to do. To test this, he recruited her 45 healthy people aged 18 to 59 who were on a relatively low-fiber diet. More than half were women. Participants were divided into her two groups and randomly assigned diets that followed the 4-week study period.
About half were assigned a diet designed by nutritionist Dr. Kirsten Barding that increased their intake of prebiotics and fermented foods. This is known as the “psychobiotic” diet because it contains foods associated with better mental health.
The group received one-on-one educational sessions with a nutritionist at the beginning and midway through the study. They should consume 6-8 servings of fruits and vegetables, 5-8 servings of grains, 3-4 servings of grains daily, which are high in prebiotic fiber (onions, chives, cabbage, apples, bananas, oats, etc.). Servings of legumes per week.
They were also told to include two to three servings of fermented foods (such as sauerkraut, kefir, and kombucha) daily. I received only
less stress
Interestingly, those on the psychobiotic diet reported less stress than those on the control diet.
There was also a direct correlation between how closely participants followed their diet and their perceived stress levels, with those who ate more psychobiotic foods over the 4-week period reported the greatest reduction in stress levels.
Interestingly, both groups improved their sleep quality, but the group following the psychobiotic diet reported greater improvement in sleep.Other studies have also shown that gut microbes are involved sleep processmight explain this link.
Psychobiotic diets have only resulted in subtle changes in the composition and function of gut microbes. Some of these chemicals are lead to mental healthThis may explain why dieting participants reported feeling less stressed.
Our results suggest that specific diets can be used to reduce perceived stress levels. This type of diet protect mental health Long-term because it targets the microbes in the gut.
While these results are encouraging, our research is not without limitations. First, the pandemic has limited recruitment, resulting in a small sample size. Therefore, long-term studies are needed.
Third, participants recorded their daily diet, but this form of measurement can be susceptible to error and bias, especially when estimating food intake. I did my best not to know which group I was assigned to, but I could have guessed based on the nutritional advice I was given. You may have given
Finally, our study only looked at people who were already healthy. This means that we do not understand how this diet affects an unhealthy person.
Still, our study provides exciting evidence that an effective way to reduce stress may be through diet. It would be interesting to know if it can be replicated for people suffering from the disorder.I will also add further evidence to this. field of studyshows evidence of links between diet, the microbiome, and mental health.
The next time you feel particularly stressed, think more carefully about what you eat for lunch or dinner. Including more fiber and fermented foods for a few weeks may help reduce stress a bit.
