Fish Consumption and Health in French Polynesia
法屬玻里尼西亞的魚類攝取與健康
摘要
法屬玻里尼西亞人像其他偏遠的濱海族群一樣，與養育他們的日常生活和文化的海洋有密切關係。他們依賴的魚類，在提供營養素的同時，也引發了潛在暴露於有害的自然和人造污染物的問題。本研究的目的是要評估在法屬玻里尼西亞攝取魚類的風險及益處。這個橫斷性研究包括了195位來自大溪地及茉莉亞島18歲以上的成人。參與者所測出血液中脂肪酸、硒及汞的濃度皆非常高。血液濃度指出硒、汞及ω-3脂肪酸有一個共同的來源，那就是攝取魚類。比較玻里尼西亞人和北方人，我們發現玻里尼西亞人血中汞的濃度和因紐特人相似（幾何平均值：90.3（15－420）nmol/L vs. 紐特人：79.6（4－560）nmol/L）。血液中硒的濃度和脂肪酸濃度也有相似結果，儘管其脂肪酸的組成有所不同。我們第一次報告南太平洋捕魚的種族跟北半球捕魚種族血液一樣，含有非常高濃度的汞、硒和ω-3脂肪酸。進一步的研究持續中，以能更具體化公共衛生營養政策。
並列摘要
French Polynesians, like other remote maritime populations are intimately connected to the ocean which nourishes their daily life and culture. Their reliance on fish raises the issue of potential exposure to harmful natural and anthropogenic contaminants as well as providing essential nutrients. The purpose of this study was to assess the risks and benefits of fish consumption in French Polynesia. This cross-sectional study included 195 adults aged 18 years old and over from the Tahiti and Moorea islands. Fatty acids, selenium (Se) and mercury (Hg) blood concentrations were measured in participants and were all very high. Blood concentrations indicate that Hg, Se and omega-3 fatty acids have a common origin, i.e. fish consumption. In comparing the Polynesian group with northern populations, we found that the Polynesian group had levels of Hg similar to those observed in Inuit populations (geometric mean (range): 90.3 (15-420) nmol/L vs. Inuit: m(r): 79.6 (4-560) nmol/L). Similar results were observed with Se blood concentrations. The fatty acid concentration was also similar to that of the Inuit population even though the specific profile of fatty acids differed. For the first time, we report very high blood concentrations of mercury, selenium and omega-3 fatty acids in a fishing population from the South Pacific, comparable to those reported among fishing populations from the Northern hemisphere. Further work is ongoing to better substantiate public health nutritional policies.
