美国“趣味科学网”近日报道,美国《海洋药物》杂志刊登的迈阿密大学一项最新研究得出惊人结论:鲨鱼翅可能有害人体健康,原因是其中所含的高浓度神经毒素会使患老年痴呆症的危险大大增加。科学家对黑吻真鲨、黑鳍礁鲨、窄头双髻鲨、牛鲨、大双髻鲨、柠檬鲨与护士鲨等7种鲨鱼鱼鳍神经毒素进行了研究。迈阿密大学大脑捐献库研究人员经过分析发现,佛罗里达海域的鲨鱼鱼鳍中含有高浓度神经毒素β-甲氨基-L-丙氨酸(BMAA),该物质与早老性痴呆症和“葛雷克氏症”(运动神经元疾病)密切相关。 According to a recent report, a recent study by the University of Miami in the United States of America, published in the United States, has come to the conclusion that the shark’s fin may be harmful to human health because of the high concentrations of neurotoxins contained in it, The risk of dementia is greatly increased. Scientists have studied seven kinds of shark fin neurotoxin such as black-necked shark, black-tip reef shark, narrow-headed hammerhead, bull shark, big hammerhead, lemon shark and nurse shark. Researchers at the University of Miami brain donation pool have analyzed that the shark fins in the Florida area contain a high concentration of the neurotoxin β-methylamino-L-alanine (BMAA), which is associated with Alzheimer’s disease and Graco S disease "(motor neuron disease) is closely related.
