Millions of people try to lower their blood pressure by cutting back on salt.
While this remains good advice, researchers now believe there is another important step that should receive equal attention.
A new scientific report suggests that eating more potassium-rich foods together with reducing sodium may provide greater benefits than reducing salt alone.
The report, published in the American Journal of Clinical Nutrition, highlights growing evidence that these two nutrients work together inside the body.
Sodium and potassium influence fluid balance, blood vessel function, and blood pressure. When sodium intake is high and potassium intake is low, blood pressure is more likely to rise.
High blood pressure affects more than 1.28 billion adults worldwide and is one of the biggest risk factors for heart disease and stroke.
Because it often develops silently without obvious symptoms, many people do not realize they have the condition until serious health problems occur. Preventing hypertension through healthy eating remains a major public health goal.
The authors reviewed current recommendations, scientific studies, and practical ways to improve diets. They concluded that advice focusing only on sodium reduction no longer reflects the full picture. Instead, they recommend giving equal importance to increasing potassium intake.
Potassium helps counter some of sodium’s effects by helping the body remove excess sodium and supporting healthy blood vessel function. Foods naturally high in potassium include leafy vegetables, beans, peas, fruit, potatoes, dairy products, and many other minimally processed foods. These foods also provide other nutrients that benefit overall health.
One reason many people consume too little potassium is that modern diets often rely heavily on processed foods instead of fresh ingredients. Processed foods usually contain large amounts of sodium but relatively little potassium. Replacing some packaged foods with fresh produce may therefore improve the balance between these nutrients.
The report also considers the food industry. Manufacturers can replace part of the sodium in certain products with potassium salts, helping reduce sodium intake across the population. However, too much potassium salt may give foods a metallic taste, so careful reformulation is needed.
The researchers stress that healthy eating patterns should be viewed as a complete package rather than focusing on one nutrient at a time. Combining lower sodium, higher potassium, regular physical activity, healthy body weight, and other positive lifestyle habits offers the greatest opportunity to lower blood pressure naturally.
People with kidney disease or certain medical conditions should speak with their healthcare provider before greatly increasing potassium intake because excessive potassium may not be safe for everyone. Personalized medical advice remains important when making significant dietary changes.
