What is Gut Flora, and Why is it Important?
The gut flora is one of the body's most underestimated systems, and at the same time one of its most important. It has an enormous impact on your health and mood, which is why understanding your gut flora is a vital step towards better wellbeing.
Gut Flora in Brief
Your gut flora, also known as the microbiome, is a collection of many billions of microbes (bacteria, fungi, and viruses) that live in coexistence with you. The gut flora resides primarily in the large intestine, where the majority are bacteria that feed on food the rest of the body cannot digest.
Depending on what you eat, these bacteria produce beneficial compounds — including what are known as short-chain fatty acids — which they deliver back to you and who help influence both your body and mind. It is therefore up to you whether you give your gut flora favorable or unfavorable conditions, not just through your diet, but also through your general lifestyle.
The Gut Flora's Impact on Your Health
The gut functions as a kind of central hub, where both the nutrients from food and the short-chain fatty acids from bacteria are absorbed and distributed throughout the body. As a result, your gut flora plays a significant role in your overall wellbeing.
You may have heard of the gut-brain axis. The gut and the brain are connected through the vagus nerve, through which they communicate and influence one another. This communication means that the gut flora has an effect on:
- Your immune system, approximately 80% of which resides in the gut
- Whether you experience inflammation in the body
- How well your digestion functions
- Your metabolism
- Your mental wellbeing
- Which vitamins are produced
Certain bacteria matter more than others, but quantity and diversity are often what determine whether there is balance and harmony in the gut. The greater the diversity of beneficial bacteria in the gut flora, the harder it is for harmful bacteria to take hold.

What Influences The Gut Flora?
No two gut floras are the same. Several factors help shape the foundation of your gut flora, depending on whether you:
- Were born vaginally or by caesarean section
- Were breastfed or bottle-fed
- Grew up in the city or the countryside
- Are an only child or have siblings
- Grew up with pets or without
However, the gut flora changes depending on how you live. Diet, exercise, sleep, stress, and medication all play a role in whether your gut flora is in balance or has been disrupted.
If you want to give your gut the best possible conditions, you can follow these guidelines:
- Eat plenty of high-fiber, fermented, and colorful foods
- Consider taking pre- and probiotic supplements
- Exercise regularly
- Spend time in nature frequently
- Get enough good-quality sleep and manage stress
- Eat slowly and chew your food at a relaxed pace
- Small changes can make a big difference to your gut flora
