15 Foods That Boost Our Immune System

 

What Is The Primary Function Of An Immune System? 

Your immune system stays at the forefront of defense against all the harmful things that enter the body to cause illness, disease, and other potential discomforts. 

In other thoughts, the immune system is your body’s defense, an army of soldiers that protect your body from harmful strangers. 

Scientifically, the immune system makes up a network of defensive pathways that combat the dangerous microbes we encounter every day. 

Immunity is grouped into two: adaptive and innate immunity. Let’s start with the innate: 

Innate immunity is basically barriers- protectors like stomach acid, skin, sweat enzymes, and cells that combat external invaders. 

Adaptive immunity studies learn from the invader and develop antibodies to destroy these invaders. 

The immunity system remembers these antigens(invaders) and combats them whenever they try to enter the body. 

 

What Influences Immune System Functionality? 

, 15 Foods That Boost Our Immune System

Your immune system is a powerful cookie and outstandingly important to provide the strength for daily activities. 

However, certain things can disrupt the immune system functionality. They include: 

 

Autoimmune disorders

Your Genetics defines you, and that’s fine. However, in some situations, genetics can lead to hypersensitivity of the immune system, a condition where antibodies attack the body cells instead of the invaders. Type 1 diabetes, rheumatoid arthritis, and lupus are popular examples of this ugly condition. 

Immunodeficiency disorders

Immunodeficiency disorders define the extreme weakness of the body’s immune system, making them susceptible to any illness. 

While genetics can sometimes cause this disorder, many people acquire them through diseases like cancer and AIDS. 

Toxins

Excessive smoking, alcohol, or environmental factors like air pollution can disrupt the ability of the body to combat antigens naturally. 

Age

When you get older, your body’s internal systems have to put in more work to function optimally. That means your system cannot produce enough antibodies without help. 

Being Overweight 

Being overweight has been linked to chronic inflammation. Although inflammation is a natural process within the immune system, chronic inflammation can destroy the immune system’s functionality. 

Poor diet

The immune system needs to be properly fueled to perform well. The deficiency of certain nutrients will reduce its ability to perform optimally. Conversely, incorporating certain nutritious foods and strategies may boost overall immune function.

Eat Healthy Foods That Improve Immunity 

So we’ve covered a few things that can influence immunity. Next is to discuss how we can improve immunity through healthy eating habits. The importance of diet for combating viruses cannot be overemphasised. 

Not only do junk, ultra-processed food lack proper body nutrients, but it also reduces the strength of the immune system. That’s why it’s important to avoid nutrients that disrupt immune cell growth and embrace nutrients tied to immune system growth.

If you opt for a citrus supplement, avoid anything higher than 2000mg daily.
