Smog in Delhi: A Hidden Threat to Health and Nutrition

As the months of October and November settle in, Delhi is enveloped by a thick smog, largely caused by stubble burning in neighboring states, local vehicle emissions, and a drop in wind speeds. This yearly pollution crisis disrupts daily routines, forces people indoors, and prompts health warnings.

While air pollution is well-known for triggering respiratory and heart issues, new research suggests it may also impact the nutrients we absorb through breathing. Studies have introduced the term “aeronutrients,” referring to nutrients that are inhaled through the lungs and nasal passages, including vital elements like iodine, zinc, and manganese.

Inhalation plays a continuous role in nutrient absorption, as we breathe in about 9,000 liters of air each day. This constant exposure allows small amounts of beneficial compounds to enter our system. For example, children living near seaweed-rich regions show fewer iodine deficiencies due to higher iodine levels in the air.

However, in cities like Delhi, where air quality is hazardous, this natural process is disrupted. Pollutants like particulate matter and toxins overshadow these helpful nutrients, making it harder for residents to benefit from aeronutrients. Additionally, harmful pollutants like manganese can accumulate in the brain, leading to serious health problems.

The poor air quality in polluted cities exacerbates nutrient deficiencies, including vitamin D, which requires sunlight for production. Experts urge that solutions should go beyond just reducing emissions, advocating for more green spaces and efforts to reduce traffic congestion for cleaner air.
