how lifestyle and diet can boost your immune system

Every day we are exposed to a wide range of potentially harmful microorganisms – such as colds, flu and even COVID. But our immune system—the network of complex pathways in our body—helps protect us from these microorganisms and other potential diseases. Basically, it recognizes foreign invaders like viruses and bacteria and immediately takes action to defend us.

Humans have two types of immunity: innate and adaptive. Innate immunity is the body’s first line of defense, consisting primarily of physical barriers (such as the skin) and secretions—including mucus, stomach acid, and enzymes in saliva and sweat—that prevent microorganisms from entering the body. It also consists of cells that attack any foreign invaders entering the body.
