The practice of consuming milk among welding professionals is often attributed to the belief that it can mitigate the potential harmful effects of inhaling certain metallic fumes. These fumes, generated during the welding process, contain metals like cadmium, zinc, and iron. The idea is that components in milk might bind with these metals, reducing their absorption into the bloodstream.
The perceived benefits of milk consumption in this context stem from the presence of calcium and proteins. Calcium is thought to compete with heavy metals for absorption, potentially decreasing the body’s uptake of hazardous elements. Proteins in milk may also bind with metals, aiding in their excretion. Historically, this practice has been passed down within the welding community, often as a precautionary measure in the absence of more sophisticated protective equipment or ventilation systems.
