About the Immune System
A network of cells, tissues, and organs work together to protect the body. White blood cells, also called leukocytes, are important. Two basic types of these cells combine to seek out and destroy disease-causing organisms or substances.
The immune system defends the body against infectious organisms and other invaders. Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease.
In most cases, the immune system effectively keeps people healthy and prevents infections. But sometimes problems with the immune system can cause illness and infection. Some people’s immune systems function better with healthy diet, lifestyle choices or genetics. But others will be more susceptible to infections.
A diet low in fresh fruits and vegetables (rich sources of vitamins, minerals, and antioxidants), and high in sugar and processed foods, can negatively impact the immune system. A stressful lifestyle and lack of exercise can also negatively affect immune system performance.
A strong immune system important throughout the year as it plays a significant role in our everyday lives.
