攝取Omega3脂肪酸 避免動脈硬化Omega3 fatty acid intake to avoid arteriosclerosis

攝取Omega3脂肪酸 避免動脈硬化 【本報綜合報導】路透報導，一項醫學研究發現，日常飲食如果大量攝取含有Omega3脂肪酸的魚油，可能有助於降低動脈阻塞，這可能是為什麼在日本的中年男子與在美國的白人男子或日裔男子相比之下，較少出現動脈阻塞的問題。 這份發表在美國心臟學院期刊（Journal of the American College of Cardiology）上的研究報告發現，在日本的日本男子血液當中的Omega3脂肪酸比例，是在美國的中年白人男子或日裔男子的2倍之多，在日本的日本男子發生動脈硬化症的比率也比在美國的中年白人男子或日裔男子來得低。 動脈硬化是因為動脈裏的血小板堆積阻塞所造成。長久累積下來，動脈將會開始硬化、變窄，最後導致例如心臟病以及中風等嚴重問題。 此外，美國洛杉磯加大（UCLA）最近發表研究報告指出，食物不僅能防治心臟病和癌症，均衡的飲食及運動還能保健大腦，有助學習成效，其中鮭魚、核桃及奇異果含有的Omega3脂肪酸功不可沒。 UCLA神經外科及生理學教授Fernando Gomez-Pinilla長期專研於食物、運動及睡眠對大腦的影響，經多年研究發現，上述3個因素對大腦健康及精神產生重要影響；飲食對提升人的認知能力、預防大腦損傷及對抗衰老有明顯作用。 他指出，鮭魚、核桃及奇異果中都發現Omega3脂肪酸，科學證明它能改善學習、記憶及幫助對抗精神性疾病，例如憂鬱、精神分裂及失智症等。 澳洲的研究也發現，396名6-12歲兒童在食用半年到一年時間含有Omega3脂肪酸以及鐵、鋅、維他命A、B6、B12、C的飲料後，學業表現比另一組沒有飲用營養飲料的學生要優秀。 相較之下，反式脂肪及飽和脂肪則對大腦認知能力及學習能力有負面作用。Gomez-Pinilla教授說，研究發現，經常食用不健康的油炸類快餐對大腦神經原及腦分子可能有破壞作用。 Gomez-Pinilla分析，日本經常食用魚類並積極運動的民眾，罹患精神性疾病的比率極低。 除Omega3脂肪酸外，葉酸對大腦的保護作用同樣不容小覷。葉酸大量存在於菠菜、橙汁及酵母中，如果缺少葉酸可能導致神經紊亂，進而造成抑鬱症和認知能力下降。 Gomez-Pinilla綜合分析160多個食物與大腦健康相關研究，該文章刊登在7月的「Nature Re-views Neuroscience」期刊上。 2008-08-25 Omega3 fatty acid intake to avoid arteriosclerosis An integrated reporting: Reuters reported that a medical study found that daily intake of food containing a large number if Omega3 fatty acids in fish oil may help reduce artery blockage, this may be why the Japanese middle-aged men and whites in the United States Japanese man or men In contrast, appear less arterial blockage problems. The American Heart Institute published in the journal (Journal of the American College of Cardiology), the study found that Japanese men in Japan Omega3 fatty acid in the blood of proportion in the United States is a middle-aged white men or two times of Japanese man As many as in Japan, a Japanese man in the rate of atherosclerosis than in the United States, middle-aged white men or more low-Japanese men. Atherosclerosis in the arteries due to obstruction caused by the accumulation of platelets. Cumulative long-term, the artery will begin to harden, narrow, resulting in such as heart disease and stroke, and other serious problems. In addition, the U.S. UCLA (UCLA) recently published research report pointed out that food not only to combat heart disease and cancer, a balanced diet and exercise but also the brain health, study results will help, salmon, walnuts and contain the kiwifruit Omega3 fatty acids功不可没. UCLA neurosurgeon and professor of physiology Fernando Gomez-Pinilla long-term research in the food, exercise and sleep on the impact of the brain, after years of study found that the above three factors on the brain and mental health have an important impact of diet on cognitive ability to raise To prevent brain damage and plays a significant role in fight against aging. He pointed out that the salmon, walnuts and kiwifruit are found in Omega3 fatty acids, it can scientifically proven to improve learning, memory and spirit to help fight against diseases such as depression, schizophrenia and dementia, and so on. Australia study also found that 396 children aged 6-12 in the consumption of six to 12 months time with Omega3 fatty acid and iron, zinc, vitamin A, B6, B12, C drinks, academic performance than the other group did not drink nutritional beverages To outstanding students. In contrast, the trans fat and saturated fat while the brain cognitive and learning ability have a negative effect. Gomez-Pinilla, said, the study found that regular consumption of unhealthy fried fast food on the brain like the original elements and may have brain damage role. Gomez-Pinilla analysis, regular consumption of fish in Japan and positive movement of people, suffering from mental diseases in a very low rate. In addition to Omega3 fatty acids, folic acid on the brain's protective effects of the same can not be underestimated. There are a lot of folic acid in spinach, orange juice and yeast, if the lack of folic acid could lead to nerve disorders, resulting in depression and cognitive decline. Gomez-Pinilla comprehensive analysis of over 160 food and brain health-related research, the article published in July of "Nature Re-views Neuroscience" journal. 2008-08-25 For more information, see World Journal News ePaper
