What is the intestinal microbiota?

Did you know that millions of microorganisms live in your body and play a key role in your health? You cannot see them, but they are there, working every day to help your body function properly. This small universe is what we call intestinal flora and its balance is essential to feeling good inside and out. 

But, what exactly is intestinal flora and why is it so important to take care of it? Keep reading, and we will explain it in simple terms.

Intestinal flora: what it is

The intestinal flora, also known as the gut microbiota, is the set of bacteria, fungi, viruses, and other microorganisms that live in our intestines. Although it may sound strange to have "little bugs" inside you, the truth is that these microorganisms are essential for keeping you healthy.

People often ask: what intestinal flora is or what intestinal flora is, and the answer is simple: it is the natural barrier that helps your body digest food, absorb nutrients, and defend itself against disease.

Fun fact: It is estimated that we have more bacteria in the intestines than cells in the entire body! That is why, when the intestinal flora is out of balance, it is easy for discomfort such as bloating, gas, heavy digestion, or even low mood to appear.

Functions of the intestinal flora

The intestinal flora has many more functions than you might imagine. Here we tell you about the main ones:

1. Facilitates digestion of food

The "good" bacteria in your intestines help break down certain foods and enable you to absorb the vitamins and minerals they contain.

2. Strengthens the immune system

70% of the body’s defensive cells are found in the intestines. A healthy intestinal flora helps these defenses function properly.

3. Protects against harmful microorganisms

Beneficial bacteria act as a natural barrier that prevents harmful pathogens from colonizing your intestines.

4. Produces essential vitamins

The microbiota produces some B vitamins and vitamin K, which are essential for your health.

5. Contributes to emotional well-being

Did you know that the intestine is known as the "second brain"? Thanks to serotonin production, intestinal flora influences your mood and mental well-being.

How can you care for intestinal flora?

Taking care of your intestinal flora is easier than you think. Here are some basic recommendations:

• Consume fiber-rich foods: Fruits, vegetables, legumes, and whole grains are the best food for your good bacteria.

• Include probiotics and prebiotics in your diet: Yogurt, kefir, sauerkraut, and fermented foods provide probiotics. On the other hand, garlic, onion, and bananas are rich in prebiotics, which feed beneficial bacteria.

• Avoid excessive sugars and ultra-processed foods: These can disrupt the balance of your microbiota.

• Stay hydrated: Drinking enough water supports intestinal transit.

• Manage your stress and sleep well: Stress and lack of sleep can alter the gut flora.
