About 1600 years ago, the Imperial Rome was pervaded by the fashion of tableware decorated with lead colored, if not directly maded of pewter (tin + lead + copper + etc.). 
Only few years ago, the scientific analysis on the bones of skeletons of Imperial Rome people revealed a rate of piomdo significantly more high than was reasonable to find. Now we know that the decline of the Roman Empire was probably due to poisoning (disorder that affects brain cells leading to madness) that struck precisely the classes abienti / managers of the time that were most likely related to fashion trends. Now let’s talk about sushi:
“Could Shshi fashion be a reply of lead problem? “
The Anisakis is a parasite that is sometimes possible to found in meat of fish. To eat parassited raw fish coud be cause of devastating parasitic diseases.
The danger is well known and therefore the restaurants to prepare the sushi, the fish must have frozen to-40C for a couple of hours (enough to disintegrate the parasite eggs and turn them into nutritious protein).
If the fish is frozen at the origin, then there is no problem, a deep-freezing at-20C ° for several days is more than enough to destroy the eggs of the parasite. We hope that restaurateurs are following the guidance of Italian ASL.
But …. another disease we may match if eat fresh fish: MINAMATE syndrome due by mercury.
Marcury it’s a “liquid” mineral that easily produces poisonous fumes (mercury thermometers and the use of amalgam for dental fillings with mercury are recently puted out of the market).
Unfortunately, mercury has been used for many years in Italian in various industrial processes that most of the time were merged industrial waste into the sea, now is not so in Italy, but abroad?
The fish we import is from where? The mercury accumulates more and more fish tissues by increasing the percentage of mercury in humans (the last link in the food chain) if eated raw.
I
n Japan Sushi are like spaghetti in Italy, and due to mercury pollution of the seas, tere are numerous cases ofMinamata syndrome (severe brain pathology).
But never fear, cooked fish has two advantages: it destroys the eggs of Anisakis (difficult to detect with the naked eye) and the heat evaporates the organic mercury in tissues of fish.
Then eat fish, because it is rich in omega 3 but … COOKED!
