Microbiota and Mental Health
In recent years, science has discovered something powerful: our gut is our second brain. The community of bacteria, fungi, and microorganisms that live in the intestines—called the microbiota—plays a key role in mental health.
Anxiety, depression, and even sleep quality are closely linked to the balance of this ecosystem.
👉 In this article, we’ll explain how microbiota impacts your mood and what small changes you can make this week to take care of it.

🌱 The gut-brain connection
The gut-brain axis is a two-way communication system between your digestive system and your nervous system.
Around 90% of serotonin, the neurotransmitter linked to well-being, is produced in the gut
When microbiota is imbalanced, it can generate inflammation and send stress signals to the brain.
A diverse microbiota is associated with lower levels of anxiety and depression.
🥗 Practical tip: include fermented foods
One of the simplest ways to support microbiota is by adding fermented foods to your diet.
Yogurt or kefir: rich in probiotics that improve gut flora.
Sauerkraut or kimchi: provide fiber and beneficial bacteria.
Kombucha: a refreshing way to add diversity.
👉 Tip for the week: add at least one fermented food per day and notice how your digestion and mood respond.
