One Gram of Salt Is The Difference For Millions of Heart Attacks

We know consuming too much salt raises blood pressure, which in turn can lead to cardiovascular problems. A 2022 study has quantified this relationship as a public health message in clear, stark terms.

Looking at health data on adults in China, the study authors estimate that a reduction of just 1 gram in daily salt intake would be enough to prevent 9 million cases of ******* and heart ******* between now and 2030.

With 4 million of those cases likely to be fatal, such a simple measure could save a lot of lives.

In China, average daily salt consumption sits at 11 grams, way above the

(WHO). The researchers pulled together the latest stats on population size, salt consumption, blood pressure and ******** rates.

“Previous estimations of the health impact of reducing salt intake in China used either obsolete or otherwise unreliable data sources and did not account for the more prolonged effect of salt reduction on blood pressure over several years,” write the researchers in their

The team looked at two other scenarios besides the single gram drop: a reduction of 3.2 grams per day (a 30 percent drop from the average) by 2025, and reducing salt intake to the recommended 5 grams per day by 2030.

If those targets are hit, up to twice as many deaths related to cardiovascular ******** could be prevented, due to the estimated reduction in systolic blood pressure.

However, the researchers emphasize that the reduction would have to be consistent over several years.

suggest most of the population wouldn’t find it too difficult to hit that 1 gram per day target.

“Other trials, on low-sodium high-potassium salt substitutes, health education to home cooks and restaurant interventions are ongoing or have recently been completed, some of which have already shown promising results,”

Cardiovascular ******** accounts for a massive 40 percent of deaths in China, with urbanization – and the associated increase in eating processed and takeaway foods – thought to be one of the main contributing factors.

While the authors of this study only looked at a potential reduction in cases of cardiovascular ********, they suggest that lowering salt intake would have multiple other benefits too. Too much salt has

The ******** government has launched a

campaign to try to hit its target of a daily salt intake of just 5 grams. That won’t be easy with a population of 1.4 billion people, but the numbers produced in this study are compelling.

“A salt reduction programme that is workable, coherent, sustainable and targeting current and upcoming major dietary sources of salt in China is urgently needed,”
