If you have chronic kidney disease, good nutrition and diet are critical components of the treatment plan. The recommended diet, including amounts of protein, calories and nutrients, changes depending on how much kidney function you have. For those beginning dialysis treatment, monitoring your diet is essential to staying healthy.

Bananas are one of the world’s most appealing fruits. A wide variety of health benefits are associated with the curvy yellow fruit. Bananas are high in potassium, Pectin, and fibre. Most of the fibre in bananas is what is called soluble fibre. It can help keep your cholesterol and blood pressure in check and help ease inflammation.

As bananas ripen, some of the resistant starch (fibre) converts to sugar meaning that a yellow banana with brown spots has more sugar and less fibre than a green banana of the same size. The glycaemic index for bananas ranges from 48–54.

Green bananas contain higher quantities of fibre and resistant starch. These get converted to sugar in yellow bananas. As green bananas are also higher in potassium content, they are not preferable when compared to ripe bananas. For patients on dialysis, it is recommended to consume 34g/small 2” pieces of ripe banana preferably one-hour pre dialysis.

Kidney patients must carefully monitor their levels of potassium to ensure they do not have too much of the mineral in their bloodstream.

Bananas are a rich source of potassium and may need to be limited on a renal diet. Consult your Dietician or health care provider to know how amount of banana you can consume in your diet based on your health condition.
