背景 提倡增加鱼类消费的健康建议需要放在全球海洋捕捞渔业可能崩溃的背景下。方法文献综述。结果在经济发达国家，官方健康饮食建议是多吃鱼，尤其是富含 omega-3 油的鱼。在许多经济欠发达国家，鱼类是人类健康的重要资产，占 26 亿人动物蛋白摄入量的 20% 以上。海洋生态学家根据目前的趋势预测，鱼类资源将在 40 年内崩溃，并建议加强对捕捞的限制，包括禁渔区，以恢复海洋生态系统的健康。用于水产养殖和其他非食品用途的鱼粉生产（2003 年为 22 公吨）似乎是不可持续的。鱼类消费的差异可能会导致国内和国际健康不平等。如果鱼类资源继续减少，这种不平等可能会加剧，而对鱼类的需求增加将加速鱼类资源的减少和海洋生态系统的健康状况。 结论 需要采取紧急的国家和国际行动来解决人类对鱼类和海鲜的需求增加以及海洋生态系统健康状况迅速恶化所带来的紧张局势。
Background Health recommendations advocating increased fish consumption need to be placed in the context of the potential collapse of global marine capture fisheries.Methods Literature overview.Results In economically developed countries, official healthy eating advice is to eat more fish, particularly that rich in omega-3 oils. In many less economically developed countries, fish is a key human health asset, contributing >20% of animal protein intake for 2.6 billion people. Marine ecologists predict on current trends that fish stocks are set to collapse in 40 years, and propose increased restrictions on fishing, including no-take zones, in order to restore marine ecosystem health. Production of fishmeal for aquaculture and other non-food uses (22 MT in 2003) appears to be unsustainable. Differences in fish consumption probably contribute to within-country and international health inequalities. Such inequalities are likely to increase if fish stocks continue to decline, while increasing demand for fish will accelerate declines in fish stocks and the health of marine ecosystems.Conclusions Urgent national and international action is necessary to address the tensions arising from increasing human demand for fish and seafood, and rapidly declining marine ecosystem health.
