Did you know that your gut houses trillions of microorganisms, and only 10% of your DNA is actually human? Understanding the importance of your gut microbiome is key to improving your overall health. 

The way we process and absorb food varies from person to person. Have you ever wondered why some people can eat certain foods without issue, while others experience discomfort? For those following the Zoe program, you're already familiar with the concept of the gut microbiome. Everyone has a unique composition of species in their gut, primarily made up of two main groups: Bacteroidetes and Firmicutes, which account for around 90% of your microbiome.

What is the Gut Microbiome? 

The gut microbiome refers to the trillions of bacteria, viruses, and fungi that live in your intestines. It’s not just a passive part of your digestive system — your microbiome plays a crucial role in your health. Your gut’s microbial composition is influenced by factors like diet, lifestyle, and other behaviours. In fact, studies suggest that the more diverse your microbiome, the better your overall health. A healthy microbiome is essential for: 

• Strengthening the barrier of the gut to protect against harmful bacteria. 
• Enhancing hormone secretion, which helps regulate sugar levels and appetite. 
• Producing essential vitamins. 
• Supporting immune system function. 
• Modulating fat storage and metabolism. 
• Promoting a healthy central nervous system. 

Gut Dysbiosis: When Things Go Wrong 

When there’s an imbalance in your gut microbiome, known as gut dysbiosis, it can lead to serious health issues like obesity, cardiovascular diseases, multiple sclerosis, and autoimmune diseases. Factors that contribute to gut dysbiosis include: 

• Lack of physical activity 
• Overuse of antibiotics 
• Poor diet, especially one high in processed foods 
• Lack of sleep 
• Chronic stress and mental health issues 
• Chemical exposure
