Abstract: Many studies suggest that fish consumption could be protective for health, but epidemiological studies on different dietary patterns show that fish-eaters have a higher cardiometabolic risk when compared to people relying on a plant-based diet not including fish. The benefit of fish consumption was related to its content of omega-3 long chain polyunsaturated fatty acids (LC-PUFAs), but toxic chemicals released into environment like heavy metals and several industrial by-products, because of their lipophilic properties, concentrate in fish fatty tissues, the same containing LC-PUFAs. Furthermore, the continuous increase in demand for fish is progressively damaging the marine biodiversity, and the volume of the fishing catch, the latter lower than the demand, made it necessary to resort to fish farming. Although meat, dairy and fish products represent dietary sources of PCBs, the latter represent the main source in human diet (respectively 9% , 19% and 67%). Methyl-mercury’s main source also seems to be fish products. Fish farming products are safer for methyl-mercury residue but other substances could be found in higher concentrations than fish caught. Moreover, ecological impact could be detrimental. From this point of view, a reassessment of the health risk-benefit ratio and sustainability of fish consumption is warranted.

Att inte äta fisk är lika mycket ett slöseri med jordens resurser som att överfiska. Att inte äta fisk är ett korkat val och att överäta fisk är också ett korkat val.

Det är inget nytt. Vi har bra koll på miljögifterna i Sverige. Metylkvicksilver är ett problem och vi ska inte äta insjöfisk så ofta. Samma sak med klororganiska ämnen som PCB och DDT i Östersjöfisk.

Vi har flera fiskar som odlas eller fångas under hållbara förhållanden. Håll er uppdaterade om nya certifierade fiskar.
