The gut is where the process of breaking down food and absorbing nutrients takes place. Nutrients from the food we eat are absorbed through the walls of the intestines into the bloodstream, where they are then transported throughout the body to support various bodily functions.Without proper digestion and absorption, our bodies cannot obtain the essential nutrients needed for energy, growth, repair, and overall health. When the gut is not working optimally there will be reduced absorption of nutrients, this can prevent healthy cell repair and regeneration as well as causing health issues.

70% the body's immune system is located in the gut. The gut-associated lymphoid tissue (GALT) plays a crucial role in defending the body against harmful pathogens, toxins, and foreign substances. A healthy gut microbiome (the community of bacteria and other microorganisms living in the gut) helps regulate immune function and prevents the overgrowth of harmful bacteria that can lead to infections and inflammation

The gut is home to trillions of bacteria, fungi, viruses, and other microorganisms collectively known as the gut microbiome. These microorganisms play essential roles in digestion, immune function, metabolism, and even mood regulation as it is in the gut that some neurotransmitters are produced.

Maintaining a diverse and balanced microbiome is crucial for overall health, as disruptions in the microbiome composition (dysbiosis) have been linked to various health issues, including digestive disorders, autoimmune diseases, obesity, and mental health disorders.

The gut and the brain are connected via a bidirectional communication network known as the brain-gut axis. This communication occurs through various pathways, including the nervous system, hormones, and immune mediators. The gut can influence brain function and vice versa, impacting mood, cognition, and behaviour. For example, the gut microbiome produces neurotransmitters and other molecules that can affect brain function, while stress and emotions can influence gut motility and function.

Emerging research suggests that the gut microbiome plays a crucial role in regulating metabolism and energy balance. Certain gut bacteria are involved in the breakdown of dietary fibres and the production of short-chain fatty acids, which can influence energy metabolism, insulin sensitivity, and fat storage. Imbalances in the gut microbiome have been associated with metabolic disorders such as obesity, insulin resistance, and type 2 diabetes

If there is permeability in the gut lining, larger particles such as undigested foods, viruses and bacteria can enter the bloodstream which will create inflammation in the body. If the permeability is not fixed but chronic there will be a constant inflammatory response taking place in the body, which over time can lead to allergies, food sensitivities, brain fog and autoimmune diseases.
