Reduce salt to improve blood pressure and heart health
A new study found that when people reduce salt, their blood pressure or existing hypertension drops. Those who have not yet been at risk can also benefit from it. Research also showed that the more sodium you take out of your diet, the higher your blood pressure will decrease.
Reduce salt and prevent heart problems
So most people benefit from a drop in blood pressure. The less salt they eat, the more chances they have of better heart health. For older people and those who already have high blood pressure, the effect, according to the researchers, is even greater. Low dietary salt intake for long periods of time could therefore likely decrease cardiovascular problems.
As part of an international collaboration, researchers carried out the latest systematic review and meta-analysis of randomized controlled trials. In which they examined the effects of reducing salt intake on blood pressure. Lead author Polly Huang said that while there was consensus among health and science organizations about reducing salt consumption in the general population, some suggested that it was of little value to people with normal blood pressure.
“Our study showed that the benefits of reducing salt intake are visible across the board. However, if you are older, already have high blood pressure and are therefore at higher risk for related diseases such as stroke and heart disease, an even greater effect on blood pressure is possible through the same amount of salt reduction. “
study results
High blood pressure is one of the main causes of premature death from a stroke or heart disease. In addition, too much salt in the diet is one of the main causes. At around 9 g per day, the average salt intake is almost twice as high as the WHO recommendations (5 g per day). Worldwide, it is estimated that excessive salt consumption causes about three million deaths each year.
Huang said that the effects of salt reduction were more pronounced at higher blood pressure levels, in old age. Almost every population group examined, however, achieved a drop in blood pressure. More importantly, salt reduction in people with normal blood pressure may prevent or delay the development of high blood pressure with age.
The results of the study would argue that population-wide salt intake is an important public health strategy to lower blood pressure and reduce the risk of stroke and heart disease.
