This is not the first time when the effects of air pollution and emission of harmful gases have been studied on the quality of crops produced. In a previously published study, experts at Harvard linked rising CO2 levels with low concentration of iron and zinc in diets. As per the experiments carried out in seven different sites spread across Japan, Australia and America, "zinc, iron, and protein concentrations in wheat grains grown at these sites were reduced by 9.3 percent, 5.1 percent, and 6.3 percent, respectively, compared with wheat grown at ambient CO2. Zinc and iron were also significantly reduced in legumes; protein was not," noted the study that was published in Harvard Gazette.
Protein, iron and zinc are some of the most important nutrients for the growth and maintenance of human body. Inadequacy of any of the nutrient may lead to deficiencies that may further trigger various health ailments. Rising air pollution is a cause of concern, it is important to take extra care of your immunity and fortify it to withstand the change in season, rise in pollution and increase in allergies and infections. Ensure consuming a balanced diet that is rich in all essential minerals and micro/macro nutrients. Exercise daily, sleep properly and keep stress at bay.
