Foods To Avoid For Optimal Kidney Health

65. Citrus Fruits – Acidity Comes at a Cost

Oranges, grapefruits, and their juices are rich in vitamin C, but they’re also packed with potassium—often over 350 mg per fruit. For healthy individuals, that’s a perk. But for those with compromised kidney function, it’s a concern. Drinking orange juice can push potassium levels past safe limits quickly, especially if consumed with other potassium-rich foods.

66. Rhubarb - The Oxalate and Potassium Combo

Often featured in pies and jams, rhubarb is a unique double-threat to kidney health. It is one of the highest natural sources of oxalates, which can bind with calcium to form painful kidney stones in susceptible individuals. For those with a history of stone formation, this alone is a significant risk. But it also contains a considerable amount of potassium, making it a food to approach with caution if you have compromised kidney function. While it’s a healthy food for many, its dual mineral content means it's best to be left off the plate for those with kidney concerns.
