Breathing polluted air, walking through muddy roads, eating fried foods and facing lot of mental stress! Seems like we all have a lot of things in common. People living and working in a metropolitan city like Mumbai have to learn to live a very hectic and stressful life. We all are increasingly being aware about the ill effects the environmental and biological toxins are doing to our health. But, unfortunately we ignore the fact and continue to live the same old lifestyle. Build up of free radicals inside the body may not show some immediate signs but slowly deteriorate our health. Free radicals are the reactive oxygen species that are formed either from normal metabolic processes in the body or consumed from external sources such as fried food items, cigarette smoke, air pollutants, industrial chemicals, etc.
