No doubt we live in an era of environmental pollution. We take in a number of pollutants from nature as well as from our home. This can be something from the cigarette smoke, vehicle smoke, dust particles, carpeting, etc. They all are responsible for producing toxins in our body. Once the body is filled with toxins it produces free radicals. For a healthy life, free radicals act as a hindrance. They cause mutation at the cell level which can lead to diseases. So it is necessary to remove toxins and thereby strengthen the immune system of the body. You can achieve this by including certain things in your diet.
