Nutritional Supplements To Counteract Harmful Effects Of Air Pollution

Air pollution is a very complex mixture of primary and secondary gases and particles, and its potential to cause harm can depend on multiple factors, including physical and chemical characteristics of pollutants, which varies with proximity to local emission sources, weather, geography and population susceptibility. It is estimated that around 80 percent of the world population lives in environments that exceed the air quality guideline (AQG) established by the World Health Organisation. The fine particulate matter (i.e. PM2.5) in traffic and industrial pollution constitutes a distinct environmental risk to human health and wellbeing. Exposure to high concentrations of PM2.5 and other pollutants has been associated with increased rates of cardiovascular and respiratory morbidity and mortality. Clinical studies have suggested that health impacts of some air pollutants (i.e., PM2.5) may be counteracted by individual intake of essential micronutrients (such as vitamins B, C, D, and E) and marine-derived long-chain polyunsaturated fatty acids (PUFAs, e.g., the Omega-3 fatty acids eicosapentaenoic acid, EPA, and docosahexaenoic acid, DHA) owing to their antioxidative and anti-inflammatory activities. Such micronutrients have been shown to reduce the PM2.5-induced reduction in heart rate variability and combat oxidative stress. The synergistic combination of the Omega-3 fatty acids and vitamin E has been cited in the treatment of air-pollution diseases. Moreover, some clinical studies have indicated the intake of antioxidants reduces inflammation, lung function, and asthma symptoms. In an air-polluted environment, a healthy diet with adequate intake of essential micronutrients may be critical to prevent the development of chronic diseases, particularly cardiovascular and pulmonary diseases. Increased intake of antioxidants, as well as other anti-inflammatory nutrients, may reduce air-pollution induced oxidative stress.
