Health and salt: unravelling the myth

There is no shortage of debate when it comes to the relationship between salt and health. Food producers, nutrition experts, and medical professionals have all shared their views over the years—often with differing conclusions. With so many opinions circulating, it can be difficult to distinguish fact from misconception. A closer look at the fundamentals helps bring clarity.

A balanced perspective

Public opinion on salt remains divided. While some specialists argue that salt consumption is excessive, others suggest that intake levels may actually be too low. Despite these opposing views, scientific research is gradually converging toward a more balanced understanding. Contrary to popular belief, there is no clear evidence that most people need to reduce their current salt intake. In fact, salt is a vital nutrient that the human body requires to function properly.

Finding the right balance

Research published in the European Heart Journal, based on studies conducted by the World Heart Federation and leading European cardiac research institutions, highlights two key findings:

• The risk of cardiovascular disease increases when daily salt intake rises above 12.5 grams (with 1 gram of sodium chloride containing approximately 0.4 grams of sodium).

• There is limited evidence to support health benefits from consuming less than 5 grams of salt per day.

Based on these findings, researchers suggest an optimal daily salt intake ranging between 7.5 and 12.5 grams.

Salt and health: a broader view

Although further research is needed to reinforce these conclusions, experts increasingly agree that salt intake should be evaluated within a broader health context. Earlier studies primarily focused on the relationship between salt and blood pressure. Today, however, research takes a more holistic approach, examining overall health effects. While low-sodium diets may slightly reduce blood pressure, they can also lead to unintended consequences and may contribute to other health concerns, such as metabolic disorders including diabetes.

Conclusion

Salt remains an essential component of a healthy, balanced diet. Only a small percentage of individuals truly benefit from significantly reduced salt intake. For the majority, excessively restricting salt can do more harm than good. A diverse diet includes a wide range of nutrients—and salt is undeniably one of them.
