What You Can Do To Build Your Immune System

The immune system is a defense system that protects against disease and is essential for life. Without an immune system, our bodies would be open to attack from organisms that can cause disease, also known as pathogens. The immune system protects us by locating and destroying these potentially harmful pathogens. This system is constantly searching for invaders, and once spotted, a complex attack is mounted.

The immune response involves white blood cells, chemicals, and other proteins. There are two main types of white blood cells. Phagocytes, which surround and destroy pathogens, and lymphocytes, which remember previous pathogens so if they appear again, they can be dealt with more quickly.

Everyone’s immune system is different but, in general, it becomes stronger during adulthood as we have been exposed to more pathogens and developed more “memory” to assist in fighting off invaders.

While our immune system is responsible for fighting off everything from the common cold to infectious viruses, we are responsible for what we put into our bodies to support a strong immune system.

We know that zinc, found primarily in animal based protein food sources and fortified grain products, supports immune function and wound healing. We also know that vitamins E and C act as antioxidants in the body, with cell-protective properties. Good sources of vitamin E include vegetable oils, whole grains, green vegetables, and almonds while good sources of vitamin C include citrus fruits, dark green and yellow vegetables, and potatoes. It is also important to note that vitamin A, found in yellow and orange fruits and vegetables such as sweet potatoes, cantaloupe, carrots and green leafy vegetables like spinach and kale, helps regulate the immune system and promotes healthy skin integrity. This is important as our skin is one component in our body’s first line of defense against pathogens.

Good nutrition is vital in maintaining a strong and healthy immune system. By eating a well-balanced diet consisting of whole grains, lean protein and a variety of fruits and vegetables, you can be sure you are doing everything in your power to support a healthy and strong immune system.
