Core Viewpoint - The World Health Organization recommends replacing regular salt with low-sodium salt to reduce sodium intake and associated health risks, particularly for certain high-risk groups [2][11][12]. Group 1: Health Risks of High Sodium Intake - Excessive sodium intake can lead to increased blood pressure, which is a major cause of cardiovascular diseases, with approximately 49% of heart disease cases attributed to high blood pressure [5]. - High salt consumption is linked to a higher risk of stroke, as it damages arteries and can lead to brain injury [6]. - High sodium diets can irritate the gastric mucosa, potentially causing acute and chronic gastritis and other gastrointestinal diseases [7]. - Overconsumption of sodium can dehydrate skin cells, accelerating aging and causing symptoms like itching and rashes [10]. Group 2: Recommended Use of Low-Sodium Salt - The World Health Organization's guidelines recommend low-sodium salt for individuals with high blood pressure, showing a significant reduction in blood pressure by 5.2/1.5 mmHg and decreasing cardiovascular events and mortality [11]. - High-risk cardiovascular patients, including those with a history of stroke, coronary heart disease, or a 10% or greater risk of cardiovascular disease in the next decade, are advised to use low-sodium salt [12][13]. - Middle-aged and elderly individuals are also recommended to switch to low-sodium salt, which helps lower blood pressure and reduce cardiovascular events without increasing overall mortality [14]. - Healthy individuals with normal blood pressure are encouraged to consider low-sodium salt to lower blood pressure and reduce the risk of developing hypertension [15]. - Caution is advised for individuals with kidney diseases, as they may face complications from potassium retention when using low-sodium salt [16].
