αναφέρεσαι σε δηλητηρίαση από μέταλλα. κ αυτά όπως κ οι λιποδιαλυτές βιταμίνες είναι τοξικά σε μεγάλη συγκέντρωση, αλλά... χωρίς την παρουσία λίπους, με την παρουσία αυτού δεσμεύονται κ είτε απορροφούνται είτε απορρίποτονται.
αυτό που θα πρέπει να σε ανησυχεί είναι ο υδράργυρος κ όχι ο ψευδάργυρος, αλλά εκεί μπαίνει το σελίνιο που περιέχουν τα ψάρια.
The best science indicates that trace amounts of mercury in the fish Americans eat simply aren't high enough to pose a health risk. But measuring only mercury further exaggerates this hypothetical risk. There's another scientific wrinkle that few environmental groups are talking about -- largely because it doesn't help to promote their scare campaigns. An accurate picture of the health consequences of eating fish must include other substances that affect the way mercury interacts with the human body.
Selenium is plentiful in fish, but the public hasn't heard much about its role in the mercury puzzle. As biochemists, pharmacologists, and neurologists study this nutrient, we're gaining a better understanding of its importance.
In scientific jargon, selenium has an unusually high "binding affinity" for mercury. In layman's terms, this means that when the two elements are found together, they tend to connect, forming a new substance. This makes it difficult for the human body to absorb the mercury separately. So when mercury "binds" to selenium, it's no longer free to "bind" to anything else -- like brain tissue.
The research world is still developing explanations for exactly how selenium cancels out mercury's potentially toxic effects, but most scientists accept one of two competing theories.
The conventional idea describes selenium as a sort of "mercury magnet." Under this theory, once selenium is digested it can locate and neutralize mercury molecules. In one study, Japanese researchers found that adding selenium to the diets of birds "gave complete protection" from large amounts of mercury. Research carried out by scientists in Scotland and the Philippines has concluded that the relationship between mercury and selenium is one of "toxicological antagonism." And in the United States, the Environmental Protection Agency describes selenium as an element that is "antagonistic to the toxic effects of mercury."
The more recent selenium hypothesis holds that mercury takes a more active role in the relationship. Under this theory, when mercury enters the body it seeks out selenium and takes it out of circulation, preventing the body from creating enzymes that depend on selenium to perform their functions. Enzymes are special proteins that control the various steps in chemical reactions that make life possible. Without enough selenium-based enzymes, the functions of the brain and other organs can be affected.
While this might sound scary, problems can only occur if we don't get enough selenium to counteract the trace amounts of mercury in the fish we eat. And fish are so rich in selenium that this is not likely to happen. The U.S. Department of Agriculture has measured selenium levels in more than 1,000 commonly consumed foods, and 16 of the 25 best sources of dietary selenium are ocean fish. University of North Dakota environmental scientist Dr. Nicholas Ralston is an expert on the relationship between selenium and mercury. Here's how he describes it:
Think of dietary selenium as if it were your income and dietary mercury as if it were a bill that you need to pay. Just as we all need a certain amount of money to cover living expenses such as food and rent, we all need a certain amount of selenium ... Only one major study has shown negative effects from exposure to mercury from seafood, and that seafood was pilot whale meat. Pilot whale meat is unusual in that it contains more mercury than selenium. When you eat pilot whale meat, it's like getting a bill for $400 and a check for less than $100. If that happens too much, you go bankrupt. On the other hand, if you eat ocean fish, it's like getting a check in the mail for $500 and getting a bill for $25. The more that happens, the happier you are.
Dr. Ralston is right. Researchers at the National Oceanic and Atmospheric Administration found that most of the fish we eat contains significantly more selenium than mercury. Seafood that contains more mercury (Hg) than selenium (Se) includes pilot whale, tarpon, marlin, and some shark. Fish we most commonly consume, including all forms of tuna and salmon, are rich in selenium.
More importantly: Mercury levels found in fish have actually DECLINED or stayed the same over the past 10 years.Τελευταία επεξεργασία από το χρήστη leangains : 17-05-09 στις 21:54

και να μη ξεχνάμε ότι τα γιαπώνια δε θα υπήρχαν ως έθνος. συγκεκριμένα το Σάββατο πήρα 3 κιλά κιτρινόπτερο, την ώρα που ψώνιζα ήρθαν 2 χαμογελαστοί κύριοι απτο Τοκυο πήραν ό,τι υπήρχε από φιλέτο, γύρω στα 7 κιλά. Τους έπιασα την κουβέντα, πολύ ευγενικοί κύριοι, τρώνε καθημερινά 2 γευματα και συχνά ωμό με κάτι σάλτσες όπως περιέγραψαν. ποιος ήρθε???
