Consuming Mediterranean diet rich in antioxidants could reduce the adverse effects of air pollution on health. A diet which includes antioxidants present in fruits, vegetables, whole grains, legumes, olive oils, fish and poultry over red meat and processed foods, can weaken the adverse effects of exposure to high levels of air pollution, says researchers.

The study showed that people who least adhered to these antioxidant-rich foods had 17 per cent higher risk of cardiovascular disease related deaths for every 10 micrograms per cubic meter increase in long-term average PM2.5 exposure, compared to 5 per cent in those who consumed such diet.
