Salt and Mortality

Does reducing salt intake increase cardiovascular mortality?

Overwhelming evidence shows that reducing salt intake from 9-12 to 5-6  g/d lowers blood pressure, thereby preventing cardiovascular disease. A recent paper claims that lower salt intake is associated with higher cardiovascular mortality despite lower blood pressure. The study is flawed and cannot refute the evidence for the benefits of salt reduction. The WHO recommends salt reduction as cruci...

Added salt and cancer mortality: confounding by smoking.

Recent changes in salt use and stroke mortality in England and Wales. Any help for the salt-hypertension debate?

This analysis attempts to fill the gap in the epidemiological evidence about the relation between dietary salt and hypertension. Changes in the purchase of salt in England and Wales are compared with changes in mortality from cerebrovascular disease (1958-78). Stroke mortality, a major sequel of hypertension, has declined in this period. Consumer purchases of salt have decreased also, as sugges...

Salt and geographical mortality of gastric cancer and stroke in Japan.

Age- and sex-adjusted mortality rates of gastric cancer and stroke in the years 1974-6 for 46 prefectures and 12 regions in Japan were related to regional differences of average per capita daily intake of salt during the period 1966-70 to test Joossen's hypothesis that salt is a common cause of both gastric cancer and stroke. While mortality rates of stroke were strongly correlated with salt in...

Dietary Salt Intake and Mortality in Patients With Type 2 Diabetes

OBJECTIVE Many guidelines recommend that patients with type 2 diabetes should aim to reduce their intake of salt. However, the precise relationship between dietary salt intake and mortality in patients with type 2 diabetes has not been previously explored. RESEARCH DESIGN AND METHODS Six hundred and thirty-eight patients attending a single diabetes clinic were followed in a prospective cohort...
