Foods you should not eat if you have high creatinine

One large orange provides about 330 mg of potassium; a glass of juice about 440–460 mg. Safer alternatives include apples, grapes, or blueberries.

Dried fruits (raisins, prunes, apricots)

Minerals are concentrated: for example, a cup of dried apricots can deliver up to 1,500 mg potassium. Best to avoid.

Potatoes and sweet potatoes

One medium potato or sweet potato contains roughly 540–610 mg of potassium. Boiling or soaking before cooking can lower the potassium level.
