Do you remember being scolded for eating too much salty snacks as a child?
Ever since, we have been taught that too much salt consumption is unhealthy.
Finally, we now realize this is true when we are confronted with the World Health Organization data saying that an estimated 1.89 million deaths annually are related to overconsumption of sodium.
In a 2022 study by Tan et al., published in BMJ Nutrition, Prevention & Health, researchers found that reducing daily salt intake by just one gram could prevent up to 9 million cases of stroke and heart attacks in China from 2024 to 2030—4 million of which would be fatal.
This simple change could make a lifesaving difference.
China is a country that is renowned for its rich culinary heritage that is enjoyed all over the world, no matter what race. However, according to a study published by The Lancet, their salt consumption ranks among the highest in the world.
China’s average daily consumption of salt is at least 11 grams a day. Yet, the recommended intake by WHO is at least 5 grams a day.
According to the study, previous research regarding the benefits of reduced salt intake in China on their health are based on either unreliable or outdated data.
Furthermore, they did not consider the long-term effects of salt reduction on blood pressure.
The study also modeled two other reduction scenarios: a daily salt-intake reduction of 3.2 grams by 2025, and 5 grams by 2025. If these goals are met, the greater reductions could double the number of lives saved.
It stressed that in order to see these effects, people must be consistent and maintain their lower salt intake over the years. School programs in China suggest that this is possible.
However, the daily five-gram reduction goal of China’s Healthy China 2030 campaign may not be as effective as it can be challenging to achieve this with their population of 1.4 billion.
On the other hand, in order to maintain the effect of the 1-gram reduction goal, other trials with promising results. were implemented— salt substitutes, educating home cooks, and urging restaurants for cooperation.
With 40% of deaths in China being caused by heart disease, increased processed food consumption, and rapid urbanisation, addressing salt intake in the country is critical.
Although the study focused on heart disease and stroke, researchers believe reduced salt intake may also lower the risk of cancer and kidney disease.
Furthermore, they advocate and called for a more practical, sustainable salt reduction targeting major dietary salt sources in China.
