10 foods that boost immunity without burning a hole in your pocket
What exactly is immunity? You can't feel immunity or see it. You can't take its pulse or its temperature. But it is extremely important for our well-being. It is the body's ability to protect itself from foreign invaders such as viruses, disease and infection. It is a system that is constantly patrolling our body to detect and destroy infectious microbes.
Fortunately, most of us are born with optimal immunity and our bodies come equipped with it, by default. Unfortunately though, with time, as we age because of environmental assaults and our less than perfect lifestyles, our immunity first becomes rusty and then slowly gets depleted. That is why it is important to keep optimising the function of this (immunity) system.
