How to support your immune system and gut microbiome


The human body has a complex system of organs, tissues and cells that work together to maintain health and fight disease. The immune system is one such mechanism that fights infection and helps the body recover from illness.

What is the immune system

The immune system is a collection of organs and cells that protect the body from infection and disease. It’s made up of two main parts, the innate immune system and the adaptive immune system.

The innate immune system includes physical barriers like skin and mucous membranes, which work to prevent harmful things from getting into your body in the first place. The adaptive immune system has several different types of cells that are able to specifically recognize pathogens (disease-causing organisms) such as bacteria or viruses and destroy them before they can make you sick.

The gut microbiome is an integral part of the immune system

The gut microbiome is an integral part of the immune system. The gut microbiome is a complex ecosystem of bacteria, fungi, and viruses that live in the gastrointestinal tract. A healthy gut microbiome helps with digestion and metabolism, and plays a role in immunity. Diet and lifestyle choices can affect your gut microbiome in both positive and negative ways.

When the immune system is activated

It’s important to understand how the immune system works. When you think of it as a complex network, it’s easy to see why simply understanding how it works can be overwhelming. If you can break down the process into smaller chunks, it becomes much easier to digest and understand.

The first step in the immune response involves identifying foreign proteins (antigens) present in the body. These proteins come from viruses and bacteria, or even our own cells when they begin multiplying out of control (cancer). This process is known as antigen presentation. The antigens are taken up by dendritic cells which then display them on their surfaces for other immune cells to recognize. In this case we’ll discuss killer T-cells since these are responsible for destroying infected cells when activated by an appropriate signal from an antigen-presenting cell like dendritic cells or macrophages

What can cause inflammation

Inflammation can be caused by many things. Some of the most common causes include:

Bacteria and viruses that enter the body through cuts or other injuries, such as chickenpox or the flu

Food allergies (for example, gluten intolerance)


Lack of sleep

Environmental toxins like cigarette smoke

What to do if you have low immunity

To stay healthy and boost your immune system, you can:

  • Eat well. A healthy diet that includes a variety of fruits, vegetables, whole grains and lean protein sources will help keep your body strong and able to fight off disease.

  • Get enough sleep. Sleep is important for many functions of the body including memory and learning, but it also plays an important role in maintaining a strong immune system. Make sure everyone in your family gets at least seven hours of sleep each night by going to bed at the same time each night; keeping electronics out of bedrooms; not having screens on before bedtime; taking baths instead of showers late at night; doing relaxing activities before bedtime like reading or listening to music (not watching scary movies!).

A healthy immune system and a healthy gut are intimately related.

The gut microbiome is an integral part of the immune system. The immune system is a complex network of cells and tissues that protects your body from infection by invaders such as viruses and bacteria. It does this by recognizing foreign invaders, then producing an appropriate response to attack them or to neutralize their effects. There are many different kinds of cells in the immune system, such as B lymphocytes (B cells), T lymphocytes (T cells), neutrophils, eosinophils, basophils, monocytes and macrophages. These different types of cells work together to fight off infections when they occur so you stay healthy!


We hope that this article has helped you to understand more about the immune system and what can cause problems with it. The gut is an integral part of the system and so its health is a crucial factor in keeping us healthy. The more we learn about how our bodies work and what they need, the better equipped we will be to treat them as well as prevent diseases like cancer or diabetes in future generations!
