The World Health Organization (WHO) has released updated guidelines emphasizing the importance of reducing sodium intake and increasing potassium consumption to combat hypertension, heart attacks, and other cardiovascular diseases. These guidelines aim to address the global health crisis caused by excessive salt consumption. With over 1.28 billion adults suffering from hypertension worldwide, the WHO’s recommendations are a timely intervention to promote healthier dietary habits and reduce the burden of preventable diseases. This article delves into the details of WHO’s new salt guidelines, their benefits, challenges, and practical steps to implement them in daily life.

Why WHO’s New Salt Guidelines Matter
The Global Health Crisis of High Sodium Intake
Excessive sodium consumption is a leading cause of hypertension, which affects over 1.28 billion adults worldwide. High sodium intake is also linked to an increased risk of heart attacks, strokes, and kidney diseases. According to the WHO, most people consume more than double the recommended daily limit of 5 grams of salt (approximately 2 grams of sodium). This overconsumption is a significant contributor to the global burden of non-communicable diseases (NCDs).
The Role of Potassium in Counteracting Sodium
Potassium is an essential mineral that helps regulate blood pressure by balancing the effects of sodium. Increasing potassium intake while reducing sodium can significantly lower blood pressure and reduce the risk of cardiovascular diseases. Potassium works by relaxing blood vessel walls and helping the body excrete excess sodium through urine.
Key Recommendations from WHO’s New Guidelines
Reduce Sodium Intake
The WHO recommends limiting sodium intake to less than 2 grams per day (equivalent to 5 grams of salt). This can be achieved by:
- Avoiding processed and packaged foods high in sodium: Processed foods account for a significant portion of daily sodium intake. Examples include chips, canned soups, and ready-to-eat meals.
- Using herbs, spices, and lemon juice instead of salt for flavoring: Natural flavor enhancers like garlic, ginger, and turmeric can reduce the need for added salt.
- Reading food labels to choose low-sodium products: Look for products labeled “low sodium” or “no added salt.”
Increase Potassium Intake
The WHO suggests increasing potassium intake to at least 3,510 mg per day for adults. Potassium-rich foods include:
- Fruits like bananas, oranges, and avocados: These are not only rich in potassium but also provide essential vitamins and fiber.
- Vegetables such as spinach, sweet potatoes, and tomatoes: Leafy greens and root vegetables are excellent sources of potassium.
- Legumes, nuts, and dairy products: Beans, lentils, almonds, and yogurt are also potassium-rich options.
Promote the Use of Salt Substitutes
The guidelines encourage the use of salt substitutes that replace sodium chloride with potassium chloride. These substitutes can help reduce sodium intake while maintaining the taste of food. Studies have shown that potassium-enriched salts can lower blood pressure and reduce the risk of cardiovascular events.
Benefits of Following WHO’s Salt Guidelines
Lower Blood Pressure
Reducing sodium and increasing potassium intake can significantly lower blood pressure, reducing the risk of hypertension and its complications. High blood pressure is a silent killer that often goes unnoticed until it causes severe health issues.
Reduced Risk of Cardiovascular Diseases
By lowering blood pressure, these dietary changes can decrease the risk of heart attacks, strokes, and other cardiovascular conditions. Cardiovascular diseases are the leading cause of death globally, and dietary modifications can play a crucial role in prevention.

Improved Overall Health
A balanced intake of sodium and potassium supports overall health by promoting proper muscle function, nerve signaling, and fluid balance. Potassium also helps maintain bone health and reduces the risk of kidney stones.
Challenges in Implementing WHO’s Guidelines
Cultural and Dietary Habits
Many cultures have dietary habits that rely heavily on salt for flavoring and preserving food. Changing these habits requires widespread awareness and education. For example, in India, pickles and papads are staple foods that are high in salt.
Accessibility of Low-Sodium and Potassium-Rich Foods
In many regions, especially low- and middle-income countries, access to low-sodium products and potassium-rich foods may be limited. Governments and policymakers need to address these barriers through subsidies and public health initiatives.
Misconceptions About Salt Substitutes
Some people may be hesitant to switch to salt substitutes due to misconceptions about their taste or health effects. Public awareness campaigns can help dispel these myths and encourage the adoption of healthier alternatives.
How to Adopt WHO’s Salt Guidelines in Daily Life
Practical Tips for Reducing Sodium Intake
- Cook at home using fresh ingredients to control salt levels: Homemade meals allow you to monitor and reduce the amount of salt used.
- Gradually reduce the amount of salt used in cooking to allow taste buds to adjust: Over time, your palate will adapt to lower salt levels.
- Avoid adding extra salt to meals at the table: Use herbs, spices, or lemon juice instead.
Incorporating Potassium-Rich Foods
- Include a variety of fruits and vegetables in your daily diet: Aim for at least five servings of fruits and vegetables each day.
- Snack on nuts and seeds instead of salty processed snacks: Almonds, walnuts, and sunflower seeds are healthy alternatives.
- Choose whole grains and legumes as part of your meals: Brown rice, quinoa, and lentils are excellent sources of potassium.
Using Salt Substitutes
- Replace regular salt with potassium-enriched salt substitutes in cooking and seasoning: These substitutes are widely available and can be used in the same way as regular salt.
- Experiment with different herbs and spices to enhance flavor without relying on salt: Try combinations like rosemary and thyme or cumin and coriander.
Conclusion: A Healthier Future with WHO’s Salt Guidelines
The WHO’s new salt guidelines provide a clear roadmap for reducing sodium intake and increasing potassium consumption to improve global health. By adopting these recommendations, individuals can lower their risk of hypertension, heart attacks, and other cardiovascular diseases. However, achieving these goals requires collective efforts from individuals, healthcare providers, and policymakers to overcome challenges and promote healthier dietary habits.
