The immune system is our body’s natural defense against diseases. That is why it is important that we boost our immune system. We need to eat more fruits and vegetables, lean protein, avoid fats, minimize eating dairy products, drink green tea, and of course exercise regularly. By doing all of the mentioned things, we can be healthy and that means that our immune system is successful, working hard seven days a week. Without our immune system, we will not be protected against diseases so we should know how to take care of it to ensure that it is properly functioning.
