How your diet affects your mood

eGood food – good mood: Is it possible to influence mental health with the right diet? Maybe you've already noticed that your mood significantly influences your choice of food? In stressful situations it can happen that we reach for unhealthy snacks more often. But have you ever thought about the fact that the other way around: Can food affect your psyche?

We know that a healthy and balanced diet is beneficial for our physical well-being. We try to influence our body shape and performance with diets. But what about mental influence? Is it possible to support our mental health with the right food?

Which foods can influence your mood?

Research in the field of “nutritional psychiatry” is attracting more and more attention. Rightly so, because it begins to reveal how our eating habits affect our mood and can thus counteract mental illnesses. A typical western diet, which is known Being low in fiber and high in fat and sugar from processed foods has been linked to a greater likelihood of psychological symptoms and disorders (1). In contrast, the Mediterranean diet rich in plant fiber has been observed to improve and reduce the risk of various health conditions, including depression and anxiety (1-3).

Recent studies have also shown that that people who adhere best to the Mediterranean diet over a longer period of time have a lower risk of developing depression than people who adhere less to it (4).

What exactly is the Mediterranean diet?

This diet is based on the traditional eating habits of the people living around the Mediterranean and is rich in fruits, vegetables, nuts, seeds, legumes, grains, fish, as well as olive oil and red wine (enjoyed in moderation!) . This diet style is generally rich in beneficial fats, polyphenols and fiber, with more protein coming from vegetables than animals. (5.9)

Diversity instead of superfood

The long list of whole foods typically consumed on a Mediterranean diet shows that it is no single “superfood” exists that can improve our well-being. Rather, there are a number of foods that can be beneficial for us.

This is also the case with your intestinal microbiome health. The more diverse your microbiome, the healthier you are. Find out now what your diversity is like.

This is because foods are complex and many different nutrients are contained in a single food. The same message is clear when it comes to our gut microbiome. No, there is no single “superfood” that nourishes all the beneficial bacteria, including us. Eating a high-fiber, plant-based diet with as much variety as possible contributes to a diverse range of prebiotics that nourish our friendly gut bacteria (6,7). If the beneficial bacteria in our intestines are well cared for, they also help us to improve our well-being and quality of life.


Gut microbiome and mood – what’s the connection?

Our intestinal microbiome is home to tons of bacteria and other microorganisms and is also called second brain designated. Within this bacterial community live species that can break down fiber and produce short-chain fatty acids (SCFAs) such as butyrate and propionate. These helpful substances play different roles in our health and well-being and may influence how well we feel. (5)


Happy gut – happy body & mind

You've probably heard of the happiness hormone serotonin. It is considered a mood stabilizer and helps us be happier, less stressed and anxious. The good news is that butyrate and propionate produced in the gut microbiome can stimulate our intestinal cells to produce serotonin (8). Almost 90% of serotonin is produced in our intestines. So if we consume sufficient amounts of fiber in our diet, we can theoretically optimize the production of SCFAs and ultimately our serotonin levels and therefore our psychological well-being.


The right diet for the gut-brain connection

Although studies show that diet can play an important role in our mental health, it should not replace treatment prescribed by qualified mental health professionals. Nevertheless, studies have proven that sticking to a plant-rich diet over a long period of time has the greatest positive impact on our gut-brain axis connection.
