The immune system is your body’s natural defence system against infections and diseases. It is a network of biological systems that work together to respond to viruses, bacteria, and other pathogens that enter the body. Like other things in the body, a good diet is essential for a strong immune system. But, before we get to the immune-boosting foods, let’s take a look at how our immune system works.
How Does the Immune System Function?
When a microbe enters the body, the innate immune system goes into overdrive to protect the body. Viruses, bacteria, fungi, and worms are examples of microorganisms. The physical barriers against these infections are skin, chemical barriers (proteins), and white blood cells.
Mucous membranes are the inner linings of the respiratory and digestive tracts. They secrete mucus, which aids in the capture of minute microbes and particles. These tracts also feature tiny hair-like projections that capture particles and provide physical protection.
Furthermore, the stomach has glands that create hydrochloric acid (HCl). It is powerful enough to eliminate any unwanted bacteria or infections that may have entered the body through eating. [1]
The human body also manufactures antimicrobial proteins that aid in the non-specific defence mechanism. When a microbe enters the body, it causes the production of these proteins to be activated. The infection is then broken down, and these proteins eliminate the dangerous infectious agents.
The large intestine contains colonies of beneficial gut bacteria that are beneficial to the body and do not cause illness or disease. These gut bacteria secrete a variety of proteins that help them survive by removing potentially hazardous microorganisms from the body.
We all know the importance of keeping our immune systems healthy and active. But it is not always easy to do so in this day and age. It is a full-time job to try and dodge all of the harmful toxins that we are exposed to, while at the same time living up to our daily responsibilities. With that in mind, an effective immunity booster is a must. We reviewed a number of immunity boosters and found Q Shield Immunity Booster one the most effective.
Nutrients’ Role in Immune System Boosting
The minerals and vitamins we consume help the complete human body work together. As a result, they play an important role in the development of our immune system. According to one study, vitamin A, D, C, E, B6, B12, and minerals such as zinc, iron, and selenium are to blame for the resistance.
Flavonoids, retinoids, and antioxidants are found in a variety of foods. These chemicals boost the immune system’s ability to fight off various illnesses. Minerals such as iron, zinc, and selenium, on the other hand, aid to stimulate the body’s reaction to infections by assisting in the creation and operation of immune cells.
The Top Immune-Supporting Foods
