盐可使血压升高的证据是,原始社会中人们摄入低盐,血压不随年龄而增高,而在工业化国家里,血压随年龄而增高,这与盐摄入量高有关。然而,工业化社会与原始社会还有许多差别,如空气污染、活动较少、随年龄增长而肥胖等等。尽管如此,有些人的高血压与摄入高盐有关。动物模型也证明高血压与摄盐有关,但有个体差异。某些大鼠、犬和猴子摄入高盐后发生高血压。Dahl的研究证明这是由于对盐的敏感性不同。另一方面,低盐常被用来治疗高血压而有效。我个人不能确定治疗 The evidence that salt increases blood pressure is that people in primitive societies consumed low salt and blood pressure did not increase with age, whereas in industrialized countries blood pressure increased with age, which was related to high salt intake. However, there are still many differences between industrialized society and primitive society, such as air pollution, less activity, obesity with age, and so on. In spite of this, some people have high blood pressure associated with high salt intake. Animal models also prove that high blood pressure and salt intake, but there are individual differences. Some rats, dogs and monkeys experience high blood pressure after high salt intake. Dahl’s research shows that this is due to the different sensitivity to salt. On the other hand, low salt is often used to treat high blood pressure and effective. I personally can not determine the treatment
