Dearm Microbes: Nova studija upozorava na otrovne arsenske spojeve u ribama!

Bern, Schweiz - Morska hrana mogla bi biti zdravstveni rizik koji mnogi još nisu razmatrali. In particular, the connection of arsenobetain, which occurs in food such as algae, fish and shellfish, is the focus of a new study by the University of Bern. This substance, which is known as "Fischarsen", has so far been considered harmless because it was associated with low toxicity and fast excretion in the body. However, research shows that the intestinal microbioma of mammals plays a crucial role in converting this connection into potentially harmful arsenic substances.

Ranije nepoznate opasnosti od Arsenobetaina

Studija je istaknula metabolizam arsenobetaina kod miševa s različitim statusom naseljavanja njegovih crijevnih mikroba. The results show that mice with a natural microbiota had a higher concentration of arsenic in the intestine and produced specific, highly toxic arsenic compounds in the large intestine. Te promjene nisu primijećene kod miševa bez klijanja, iako je izlučivanje arsena uglavnom bilo sporije. "So intestinal microbes play a crucial role in the metabolism of arsenobetain in the body. In this case, however, the microbioma seems to have a harmful effect," explains the microbiome expert Siegfried Hapfelmeier.

Činjenica da Arsenobetain trenutno nije toksična i stoga nije podložna zakonskoj granici mogla bi biti zabludu za mnoge potrošače. Ova nova otkrića postavljaju ozbiljna pitanja o sigurnosti morskih plodova i mogu se pozivati na ponovnu procjenu trenutnih smjernica. Kao Danas.
