Foods That Actually Damage Your Kidneys

2. Potatoes

Potatoes are a staple food in many countries. However, potatoes (and sweet potatoes too) are rich in potassium. Just 150 grams of potatoes may contain up to 600 mg of potassium, making them unsuitable for consumption by those following a renal diet.

There are not a lot of substitutes available for potatoes, although you can eat cassava if it is available where you live. Fortunately, potatoes can be “leached” to reduce their potassium content. This means boiling them for 10 minutes or simply soaking the potatoes in water. Leaching will reduce the potassium content considerably, making more suitable for eating.
