Daily Salt Intake Recommendations: How Much Salt Do You Need Per Day?
WHO Guidelines on Salt Intake
The World Health Organization (WHO) recommends that adults consume less than 5 grams of salt per day to reduce the risk of cardiovascular diseases 124. This recommendation is based on extensive research linking high salt intake to increased blood pressure and subsequent cardiovascular issues.
Current Salt Consumption Levels
Despite these guidelines, the average salt intake in many regions far exceeds the recommended levels. For instance, in the WHO European Region, most countries report salt consumption well above the 5-gram threshold, with men generally consuming more salt than women . Similarly, in South Asian countries, salt intake ranges from 6.7 to 13.3 grams per day, significantly higher than the recommended amount .
Health Implications of High Salt Intake
High salt intake is strongly associated with various health issues, including hypertension, cardiovascular diseases, and even stomach cancer 78. Reducing salt intake to the recommended levels can lower blood pressure in both hypertensive and normotensive individuals and decrease the risk of cardiovascular diseases .
Challenges in Reducing Salt Intake
Reducing salt intake is challenging due to its widespread use in food products for taste, preservation, and texture. Efforts to reduce salt in food products without compromising taste or shelf-life are ongoing, but achieving significant reductions requires a multi-stakeholder approach, including consumer education and food industry reformulation 27.
Conflicting Evidence and Recommendations
While the WHO and other health organizations recommend a daily salt intake of less than 5 grams, some studies suggest that the evidence supporting these low levels is not robust. For example, some research indicates that a salt intake below 5.8 grams may not have significant health benefits and could even activate adverse physiological responses 59. This has led to calls for a redesign of salt dietary guidelines to reflect more nuanced evidence .
Conclusion
In summary, the WHO recommends a daily salt intake of less than 5 grams to mitigate the risk of cardiovascular diseases. However, current consumption levels in many regions are significantly higher, posing substantial health risks. While reducing salt intake is challenging, it is essential for improving public health. Ongoing efforts in food reformulation and consumer education are crucial to achieving these targets. Despite some conflicting evidence, the general consensus supports reducing salt intake to improve health outcomes.
