Evidence Shows We Can Absorb Vitamins and Minerals From the Air

Recent research suggests that humans can absorb various vitamins and minerals from the air, a concept known as 'Aeronutrients'. The human respiratory system, including the nose and lungs, is highly efficient at absorbing airborne particles, potentially providing essential nutrients that supplement our diet. This emerging field has implications for public health and urban planning, especially in cities where air quality can be poor.

Airborne Nutrient Absorption

• 00:00:00 The human body can absorb nutrients like iodine, zinc, and manganese from the air through the respiratory system, a concept termed 'Aeronutrients'. These nutrients can supplement a person's diet and potentially alleviate deficiencies. This absorption occurs through the nose and lungs, specifically using cilia and receptors to transfer particles directly into the bloodstream.

Iodine Absorption

• 00:02:45 Studies from the 1960s showed that laundry workers exposed to iodine in the air had higher iodine levels in their blood and urine, indicating absorption through inhalation. A 2011 study linked elevated iodine levels in children near seaweed-rich coastal areas to airborne iodine, independent of their diet, suggesting it can supplement dietary iodine intake.

Manganese and Zinc Absorption

• 00:04:09 Manganese and zinc can enter the brain through neurons in the nose and are essential nutrients. Welders exposed to manganese in the air can have high levels of manganese in their bodies, suggesting that certain professions require consideration of airborne manganese. While too much manganese can be harmful, it highlights the absorption of minerals through the respiratory system.

Respiratory System Efficiency

• 00:06:00 The respiratory system, particularly the lungs and nose, is highly efficient at absorbing particles from the air, directly transferring them into the bloodstream. This is in contrast to the digestive system, which processes food through various stages before nutrients are absorbed. The cilia in the nose and lungs can absorb larger molecules than the digestive system, including vitamins, minerals, and even some medications.

Future Research and Implications

• 00:09:31 Further research is needed to fully understand the effects of 'Aeronutrients' and how different environments impact nutrient absorption. This field could have major implications for public health and urban planning, especially in cities with poorer air quality. This research could lead to guidelines for creating more livable and healthier urban environments by managing the inhalation of 'Aeronutrients'.
