Prone to peroxidation of unsaturated fatty acids, eating too much fish oil, without restraint, it will cause side effects. Life, such as senile plaques is a manifestation of peroxide.
Even more serious is also possible mercury poisoning.
U.S. Food and Drug Authority (FDA) and the U.S. Environmental Protection Agency jointly issued a notice, according to U.S. scientists for many years of monitoring and research, marine fish contain high levels of methylmercury.
Mercury is a heavy metal, mercury levels slightly exceeded the human body harm in adults although not obvious, but it can damage children's nervous system. In this perspective, the experts recommend that children, pregnant women should be minimal consumption of deep-sea fish and fish oil.
Reporter from the Peking University Health Science Center School of Public Health Professor Song Wenzhi there understand the phenomenon of fish mercury first appeared in the early 70s in Japan, where the fishermen had an outbreak of a kind of strange diseases, "Minamata disease."
Professor Song Wenzhi show a causal relationship: Japanese chemical plant mercury emissions continue to sea water, sea water after digestion of mercury by plankton into organic mercury, or methylmercury, shrimp eat the plankton after the accumulation of mercury in their body, and then small fish eat shrimp, in the food chain, mercury is continuously gathered, until the sharks and other fish of the body, their toxicity is many times higher than the original.
"Plankton can make mercury methylation, which is a carry of two methyl mercury, methylmercury into Hg (CH3) 2." Professor Song vividly hand gestures, "one of the major features of methylmercury is able to pass the body's blood barrier directly on the nerve center of human destruction. "
Professor Song said that the symptoms of mercury poisoning are ataxia, crazy.
But the FDA's experts say it is not necessary at the mere mention of fish, some fish can still be eaten in moderation, like salmon, shrimp, tuna fish. They suggested that this type of seafood consumption per week should be less than 340 grams, and other seafood, including shellfish, such as white tuna, weekly intake should not exceed 170 grams. In this regard, Professor Song is agreed, he said, like genetically modified foods, we can not find a reason to fear it.
