Resumen:
In contrast to the health benefits of a balanced diet, a point of interest related to regular consumption of certain foods is the risk from potential exposure to toxic substances, which are also present in these. In recent years, most studies of national and international dietary intake of contaminated chemicals, the tests were conducted in uncooked foods. However, the physical qualities and nutritional qualities of a number of foods can be largely modified by the processes of cooking. The present study provides an overview of the current state of chemical contamination in cooked foods most consumed in Catalonia. Have analyzed the different food groups as well as various cooking techniques. Contaminants evaluated include: arsenic (As), cadmium (Cd), mercury (Hg), lead (Pb), dioxins and furans (PCDD / Fs), polychlorinated biphenyls (DL-PCBs), polychlorinated diphenyl ethers (PCDEs), ethers polybrominated diphenyl (PBDEs), hexachlorobenzene (HCB), polycyclic aromatic hydrocarbons (PAHs) and perfluorinated compounds (PFCs). Perhaps most important is that the result was not found any way of cooking that significantly and all food and contaminants evaluated, significantly alter the content of pollutants. However, the results of the study can be useful as a guide for the selection of different cooking techniques to prepare a healthy diet with low toxicity.
