The Gut Microbiome and Its True Impact

You are what you eat – you've probably heard this phrase before. It means that the type and quality of your food directly impact your health and well-being. This is partly due to your gut microbiome. Here we explain what it is, why it's important, and how you can support it.

What Is the Microbiome?

The gut microbiome, also known as the gut flora, consists of all microorganisms living in the human digestive tract. It includes trillions of bacteria – more than the number of cells in the human body. Other components include fungi, archaea, viruses, and yeasts. A healthy gut microbiome is characterized by high diversity and balance among these microorganisms, which is crucial for our health. Each person has a unique composition of gut flora.

Types of Gut Bacteria and Their Functions

It is estimated that around 1,000 different species of bacteria or more live in the gut. Gut bacteria help digest food and synthesize vitamins. They also prevent pathogens from spreading and contribute to a functioning immune system.

The gut flora can be divided into four phyla:
- Firmicutes
- Bacteroidetes
- Proteobacteria
- Actinobacteria (such as Bifidobacteria)

Firmicutes are responsible for breaking down fibre, Bacteroidetes prevent the colonization of pathogenic microbes, and Proteobacteria digest proteins.

Bifidobacteria, belonging to the Actinobacteria group, are one of the dominant bacterial groups. Should you buy gut bacteria, they will likely include Bifidobacteria. These bacteria naturally colonize the gut and have important roles, such as displacing pathogenic bacteria and producing serotonin, the happiness hormone. Therefore, Bifidobacteria play a significant role in the gut-brain axis. Serotonin influences mood, pain perception, sleep-wake cycles, and appetite, highlighting the importance of the gut-brain axis.

The Role of the Gut-Brain Axis

The gut-brain axis is a fascinating network connecting our digestive system and brain. This communication system affects our mood, behaviour, and cognitive functions. The gut sends signals via the enteric nervous system and chemical messengers like hormones and neurotransmitters to the brain. Conversely, the brain can regulate gut function, showing how closely our mental and physical states are linked. Current research on this axis provides exciting insights into the relationships between diet, mental health, and overall well-being.

Factors Influencing the Gut Microbiome

Lifestyle and diet significantly influence gut flora. The microbiome thrives on healthy foods, particularly fruits, vegetables, legumes, and whole grains, which are rich in fibre. Antibiotic use can greatly impact the microbiome, and taking gut bacteria can help restore it. You can buy gut bacteria, or find good prebiotic sources in onions, bananas, parsnips, and asparagus.

Signs of an Unhealthy Gut Flora

A healthy gut contributes to overall well-being. Signs of an unhealthy gut include:
- Frequent colds
- Food intolerances
- Bloating
- Chronic inflammatory bowel diseases

An unbalanced diet can disrupt the gut flora, requiring regeneration to support the microbiome.

Dietary Tips for a Healthy Gut Microbiome

The microbiome is sensitive to external influences. A balanced diet is key to supporting gut bacteria. Eat a varied diet rich in fibre, fermented, and probiotic foods. Avoid sugar and highly processed foods, and drink plenty of water.

General Tips for Supporting a Healthy Gut Microbiome

The microbiome can be affected by various factors, including stress and medication use. It is also sensitive to alcohol and tobacco consumption. Probiotic foods, which contain lactic acid bacteria and yeasts found in yogurt, buttermilk, and kefir, help strengthen the gut flora. If you don't consume enough probiotic foods, it might be helpful to buy gut bacteria supplements containing Lactobacillus casei or Bifidobacteria.

Here are some tips for supporting your gut flora and promoting a healthy microbiome:

  • Avoid stress as much as possible and maintain good sleep hygiene.
  • Reduce stress through yoga and exercise.
  • Limit alcohol and cigarette consumption.
  • Drink enough water to help move food through the intestines.
  • Eat a fibre-rich diet.
  • Regularly consume yogurt, cheese, or fermented foods like sauerkraut or kimchi, and drink buttermilk or kefir. Animal-based dairy products are particularly rich in Bifidobacteria.
  • You can also take gut bacteria supplements to support your microbiome.
