Patient discussion about orange

Q. My family doctor advised me to cut smoking and to have more orange juice and didn’t give any meds.Why is it so I work in suburban zone in a construction site. My worksite is very dusty and polluted as lot many industries also exist there. While coming home I face huge traffic pollution. It’s a 1 hour journey. This creates stress to me. My family doctor advised me to cut smoking and to have more orange juice and didn’t give any meds. Why is it so?

A. YEah, probably your doctor believes that by increasing amount of anti-oxidants inside your body, your body will be able to fight the negative effect from the pollution.
the chemical pollution can come from anywhere in our daily living. that's why it is recommended for all of us to strengthen our body defense by eating healthy foods (and even consume multivitamins), and stop the activities that will harm our body (such as smoking, alcoholic drinks, etc.).

Fruits and some vegetables (you can try: orange, apple, berries, tomato, grapes, etc.) are believed to have high content of anti-oxidants, so it will help our body to remain healthy.
Good luck and stay healthy always!
