A potassium rich diet could help prevent kidney and heart problems in people with type two diabetes.
Because diabetics are at an increased risk of kidney failure and heart disease, researchers in japan wanted to see how diet played a role.
The study of 600 patients revealed potassium was linked to a slower decline in kidney function and fewer cardiovascular complications.
Dark leafy greens, squash, bananas and fish are high in potassium.
Sodium levels were not associated with kidney or heart health.
