Surprising Findings
The risk jumps dramatically only at the very top of the Na–K scale, not steadily across all levels.
Most people assume more salt = steadily more risk, but this study found a threshold effect—your body might handle moderate imbalance, but collapse at the extreme.
Practical Takeaways
Replace one salty snack a day (like chips or ramen) with a potassium-rich food (banana, sweet potato, avocado).

Eating too much salt compared to potassium might be worse for your heart over time than just looking at salt or potassium by itself.
In Japanese adults, eating too much sodium compared to potassium is linked to a higher risk of dying from heart disease or stroke — but only when the ratio gets really high, like past a certain point.
If Japanese adults eat more sodium compared to potassium in their diet, they’re more likely to die from any kind of stroke — including both bleeding and clot-related strokes — over time.
In Japanese adults, eating more sodium compared to potassium may increase the risk of dying from a type of stroke called haemorrhagic stroke, especially over a long time.
If Japanese adults eat more sodium compared to potassium in their diet, they’re more likely to die from heart disease over time.
