It is often suggested that the weak epidemiological relationship between dietary sodium and blood pressure may reflect a stronger relationship within a susceptible subgroup. The evidence in favour of this explanation is reviewed, and found to be insubstantial. A more consistent explanation of the available data is that there is a weak general effect of dietary sodium on blood pressure acting on the general population. This conclusion has important practical implications for food and health policies.
人们常认为，饮食中钠与血压之间微弱的流行病学关系可能反映了在易感亚组中存在更强的关系。本文对支持这一解释的证据进行了综述，发现其并不充分。对现有数据更一致的解释是，饮食中钠对普通人群的血压有微弱的总体影响。这一结论对食品和健康政策具有重要的实际意义。
