The traditional Inuit diet includes wild birds, fish and marine mammals, which can contain high concentrations of the neurotoxicant methylmercury (MeHg). Hydroelectric development may increase MeHg concentrations in traditional foods. Consumption advisories are often used to mitigate such risks and can result in reduced intake of traditional foods. Data from a dietary survey, MeHg exposure assessment and risk analysis for individuals in three Inuit communities in Labrador, Canada (n = 1145) in 2014 indicate reducing traditional food intake is likely to exacerbate deficiencies in n-3 polyunsaturated fatty acids and vitamins B12 and B2. Traditional foods accounted for < 5% of per-capita calories but up to 70% of nutrients consumed. Although consumption advisories could lower neurodevelopmental risks associated with an increase in MeHg exposure (90th-percentile ∆IQ = - 0.12 vs. - 0.34), they may lead to greater risks of cardiovascular mortality (90th-percentile increase: + 58% to + 116% vs. + 25%) and cancer mortality (90th-percentile increase + 2% to + 4% vs. no increase). Conversely, greater consumption of locally caught salmon mostly unaffected by hydroelectric flooding would lower all these risks (90th-percentile ∆IQ = + 0.4; cardiovascular risk: - 45%; cancer risk: - 1.4%). We thus conclude that continued consumption of traditional foods is essential for Inuit health in these communities.

与拉布拉多因纽特人传统食品咨询相关的风险权衡。

传统的因纽特人饮食包括野生鸟类，鱼类和海洋哺乳动物，其中可能含有高浓度的神经毒性甲基汞（MeHg）。水力发电的发展可能会增加传统食品中甲基汞的含量。消费咨询通常用于减轻此类风险，并可能导致传统食品的摄入减少。2014年来自加拿大拉布拉多三个因纽特人社区（n = 1145）的饮食调查，MeHg暴露评估和风险分析的数据表明，减少传统食物摄入量可能会加剧n-3多不饱和脂肪酸和维生素B12和B2。传统食品占人均卡路里的5％以下，但所消耗的营养成分却高达70％。尽管消费咨询可以降低与MeHg暴露量增加相关的神经发育风险（90％ΔIQ=-0.12 vs.-0.34），但它们可能导致更高的心血管死亡率风险（90％百分比：+ 58％至+ 116 ％vs. + 25％）和癌症死亡率（第90个百分点增加+ 2％到+ 4％，而不增加）。相反，更多地消费当地捕获的鲑鱼（主要不受水电洪水影响）将降低所有这些风险（90％ΔIQ= + 0.4；心血管疾病风险：-45％；癌症风险：-1.4％）。因此，我们得出结论，继续食用传统食品对于这些社区的因纽特人健康至关重要。+ 25％）和癌症死亡率（第90个百分点增加+ 2％至+ 4％，而无增加）。相反，更多地消费当地捕获的鲑鱼（主要不受水电洪水影响）将降低所有这些风险（90％ΔIQ= + 0.4；心血管疾病风险：-45％；癌症风险：-1.4％）。因此，我们得出结论，继续食用传统食品对于这些社区的因纽特人健康至关重要。+ 25％）和癌症死亡率（第90个百分点增加+ 2％至+ 4％，而无增加）。相反，更多地消费当地捕获的鲑鱼（主要不受水电洪水影响）将降低所有这些风险（90％ΔIQ= + 0.4；心血管疾病风险：-45％；癌症风险：-1.4％）。因此，我们得出结论，继续食用传统食品对于这些社区的因纽特人健康至关重要。
