Scientists have uncovered a surprising fact: the air we breathe could be a valuable source of essential nutrients. A recent study published in Advances in Nutrition, sheds light on the concept of "aeronutrients," substances that can be absorbed through the respiratory system.
The concept of "aeronutrients" introduces the idea that humans can absorb certain nutrients from the air, complementing the nutrients obtained through diet. This perspective, highlighted in a recent article in Advances in Nutrition, suggests that essential nutrients like iodine, zinc, and manganese can be inhaled, which is supported by scientific evidence.
Breathing is a constant process, with individuals inhaling approximately 9,000 liters of air daily. This continuous exposure allows for the accumulation of beneficial components, even in small concentrations. While much research has focused on the negative impacts of air pollution, the potential health benefits of clean air and its nutrients have been largely overlooked.
Aeronutrients are absorbed through various pathways in the body, including the nose and lungs, where larger molecules can enter the bloodstream more effectively than through the digestive system. Historical studies have shown that individuals exposed to certain airborne nutrients, such as iodine, have higher levels in their bodies, indicating that these nutrients can indeed be absorbed through respiration.
Historical studies support the concept of aeronutrients. For instance, laundry workers in the 1960s exposed to airborne iodine showed increased iodine levels. Similarly, children living near seaweed-rich coasts in Ireland had higher iodine levels due to atmospheric iodine gas.
According to NewsBytes, Manganese and zinc can also enter the brain through nasal neurons, further validating the absorption of nutrients through inhalation. Aerosolized vitamins, like vitamin B12, offer a promising solution for nutrient deficiencies.
Further research is needed to identify which components of air can be classified as aeronutrients and to explore their potential health benefits. This could lead to innovative approaches in nutrition, such as aerosolized forms of vitamins to address deficiencies, particularly in environments with limited dietary options. Ultimately, understanding aeronutrients may reshape nutritional guidelines and encourage spending more time in nature to enhance overall health. The story is from The Conversation.
