We have all heard the phrase ‘I have a gut feeling’ or ‘gut-wrenching’ experience and other variations of gut and our feelings. However, are they just phrases or do they hold some truth to them. There have been many studies that show how your mental health affects your gut and vice versa. People have expressed how when they are scared or angry or anxious they often experience an upset stomach with other people also experiencing some sort of sudden reaction with heightened feelings whether it is a lurch or a sudden ‘drop’. So, if these things affect your gut, then can helping your gut make you feel better? A new study shows that a happy gut could mean a happy you. A recent study published in the npj Mental Health Research found that people who took probiotic supplements, which contain live microorganisms, reported feeling better emotionally over a month. Interestingly, these probiotics didn't seem to change people's overall mood as measured by standard psychological questionnaires. The study explained that "negative feelings" can mean different things to different people. She believes this finding is significant because it suggests probiotics might help with whatever an individual interprets as a negative emotion, whether it's anxiety, sadness, or tiredness. What Are Probiotics? The types of microbes that thrive in our gut are largely determined by the food we eat and what those microbes do because of this, companies and researchers have developed probiotic supplements containing specific strains of live microorganisms. The goal is to see if these supplements can improve health. Probiotics, usually sold in capsules or pills, are defined as live microorganisms that provide a health benefit when consumed in adequate amounts. These beneficial microbes are also naturally present in some fermented foods like yogurt. How Do Probiotics Directly Affect Your Mood? The study involved 88 healthy individuals. For one month, half of the participants took a daily probiotic supplement, while the other half took a placebo (a dummy pill with no active ingredients). The probiotic used was a mix of nine different bacteria strains found in the Ecologic Barrier mixture from a Dutch company. Participants mixed a sachet of these bacteria with lukewarm water each day. At the beginning and end of the study, everyone completed ten different questionnaires about their emotions and how they processed them, as well as one about any bowel issues. Participants also rated how positive or negative they felt each day on a scale and provided stool samples. The results showed that both the placebo group and the probiotic group: Scored similarly on the mood questionnaires.Reported similar levels of good mood each day.However, the group that took probiotics said their negative mood went down after just two weeks. This difference between daily feelings and the questionnaires suggests we might need better ways to measure mood changes. How the Gut And Brain is Connected? Harvard Health Publishing explains that our gut and our brain are closely linked, so much so that how we feel emotionally can directly affect our stomach and intestines, and problems in our gut can also send signals to our brain, influencing our mood. Think about how stress can give you "butterflies" or how worry can make you feel sick to your stomach – these common feelings show this strong connection because of this, when our gut is upset for no clear physical reason, it's important to consider how our stress and emotions might be playing a role, as our mental state can actually change how our digestive system works and how sensitive we are to pain in our gut.
