The Gut-Brain Connection: Why Your “Second Brain” Is Just as Important

Introduction: "I Have Butterflies in My Stomach" – Where Does This Gut-Brain Connection Come From? 🦋🤔

We have all used phrases like “I have butterflies in my stomach” or “my stomach turned.” When we face emotions, we often feel like our stomach is the first to react. These aren’t just phrases, it’s a real physical connection between our brain and gut, called the “gut-brain axis.”

Science has proven that the gut and brain communicate both ways, and this connection has a significant impact on our mood, thoughts, and mental health.

Fascinating, isn’t it?

Why Do We Talk About the Gut Instead of the Stomach? 🤷‍♀️🍏

Although we often say “stomach” in everyday language when we feel butterflies or discomfort, this term is not precise from a scientific perspective. The brain is actually not directly connected to the stomach but to the intestines. When we talk about the “gut-brain connection,” the term “gut” in science refers to the entire digestive system, especially the intestines, where there is a huge community of bacteria, the microbiota.

The intestines are truly the “second brain” because they have their own nervous system, known as the enteric nervous system, and produce hormones like serotonin. Communication between the gut and brain (the gut-brain axis) happens through the nervous system (vagus nerve), hormones, and immune signals. So, it’s not the stomach that “thinks,” but the intestines and their bacterial composition that have a powerful influence on the brain.

The Gut as the "Second Brain" and a Guide to the Microbiota 🧬🍽️

What are the intestines and why are they so important?

The intestines contain millions of neurons, which is why they are often called the “second brain.” Interestingly, up to 90% of serotonin, the happiness hormone, is produced right in the gut!

This means our gut microbes directly affect how we feel, behave, and even think.

The gut microbiota is a community of trillions of microorganisms, some good, some bad. The key is balance. If the gut is out of balance, it can have serious effects on our mental health.

Do All Foods Affect Your Mood? 🍌🍫🤔

We all know that bananas can improve mood, and dark chocolate can boost concentration. But what about other foods?

Many are neutral, but… not all!

Besides foods that help us feel better, there are those that can cause problems.

For example, a high intake of processed foods, refined carbs, and sugars can increase inflammation in the body and disrupt the balance of gut bacteria. This can lead to brain fog, reduced focus, and worsened mood.

Recent studies highlight a strong link between our diet, gut health, and mental state, even connecting the food we eat to emotional problems such as stress and anxiety.

In this article, we want to shed light on this new understanding because proper nutrition for a happy brain and healthy gut is not just about what to eat but also about what to avoid.

Nutrition for a Happy Brain: Feed Your Gut, Feed Yourself 🥗🧠

Fermented Foods: Natural Probiotics 🥛🫛

Fermented products contain natural probiotics that help maintain a healthy gut microbiota.

Here are some foods you might want to include in your diet:

  • Kefir: Rich in probiotics, easy to add to smoothies.

  • Sauerkraut: An affordable source of probiotics to add to meals.

  • Kombucha: A popular fermented tea that can be enjoyed as a healthy drink.

Prebiotics: Food for Good Bacteria 🌿🍌

Prebiotics are “food” for the good bacteria in the gut. Eating foods rich in prebiotics helps the growth of beneficial bacteria.

Here are some foods to include:

  • Onions, garlic: Natural prebiotics that help maintain a healthy microbiota.

  • Bananas (especially slightly green): Contain fibers that feed good bacteria.

  • Oatmeal: A perfect breakfast option rich in prebiotics.

Foods to Avoid 🚫🍔🍬

Some foods can disrupt gut balance and affect our mental health.

Here are foods to avoid:

  • Processed foods and sugar: These feed bad bacteria and can trigger inflammatory processes.

  • Artificial sweeteners: Some studies suggest they can negatively affect gut microbiota.

Personal note

You might have noticed that after indulging in fast food, you feel not only physically tired but also mentally “slow.” The same happens when you overeat bakery items — even though you had breakfast, you feel exhausted because it doesn’t keep you full for long.
