Heavy metals, particularly lead and cadmium, are common contaminants in vegetables, and their presence poses a significant risk to human health. Food preparation and processing methods can substantially influence the concentrations of these metals in vegetables. The aim of this literature review is to analyze the changes in lead and cadmium concentrations that occur during various vegetable processing techniques, such as blanching, boiling, fermentation, and microwave heating. This paper includes data from relevant scientific studies that report how the concentrations of these metals vary depending on the type of process and vegetable involved. The review highlights that certain processing methods can significantly reduce the levels of lead and cadmium, which is crucial for decreasing consumer exposure. Blanching and boiling have shown greater reductions in cadmium content up to 42.6% and 58.3% respectively, compared to lead, where reductions were below 9.8% during blanching and below 6.7% during boiling processing. In the case of vegetable fermentation, lead showed a higher reduction (up to 18.7%) compared to cadmium (up to 12.9%). These findings have practical implications for improving the safety of plant-based food products and can inform both consumers and the food industry about processing methods that help lower heavy metal intake through diet.
