Could a Simple Salt Swap Improve Your Health? WHO’s New Guidelines Offer a Solution

For years, health experts have warned about the dangers of excessive sodium consumption, yet global intake remains alarmingly high. The World Health Organization (WHO) has sounded the alarm once again, releasing new guidelines in January 2025 that urge people to switch to low-sodium salt substitutes.

The statistics are staggering—1.9 million deaths each year are linked to high sodium intake. Despite numerous public health campaigns, global sodium consumption still averages 4.3 grams per day, more than double WHO’s recommended 2 grams. The consequences? Increased risks of high blood pressure, heart disease, kidney disease, osteoporosis, and even certain cancers.

WHO’s proposed solution is simple: swap out regular table salt for potassium-enriched alternatives. Unlike sodium chloride, which raises blood pressure and puts strain on the heart and kidneys, potassium chloride can provide a salty flavor while potentially offering health benefits, as most people don’t consume enough potassium.

Yet, changing dietary habits is easier said than done. Experts like Xiaoyue (Luna) Xu from UNSW Sydney and Bruce Neal from the George Institute for Global Health acknowledge that reducing salt intake has historically been difficult. People are accustomed to the taste of salt, and altering food preparation methods requires effort. However, with proper education and food industry support, this shift could save lives.

Of course, potassium-enriched salt isn’t suitable for everyone. Individuals with kidney disease or conditions that affect potassium levels should consult their doctors before making the switch. But for most people, this change could be a win-win—maintaining flavor while reducing sodium-related health risks.

Beyond salt substitutes, WHO also recommends simple strategies to cut sodium intake:

• Avoiding highly processed foods
• Removing salt containers from the dining table
• Using herbs and spices instead of salt in cooking
• Choosing products labeled as low in sodium

As the world grapples with rising cases of hypertension and heart disease, this global push for salt reduction is timely. The question remains: will individuals and the food industry embrace this small but potentially life-saving change?
