For people with reduced kidney function, it may be necessary to limit fluids, making it difficult to use juices as a way to get the recommended servings of fruits and vegetables. Certain nutrients may need to be limited because the kidneys can't filter them from the body effectively. Unless a person is at risk of developing kidney stones, beets may be key to reducing the risk of kidney (kidney) failure during and after a heart x-ray. Coronary angiography is a specialized test that allows doctors to see the blood vessels in the heart in action.
Unfortunately, health experts warn that juices and juice cleanses can have adverse health effects. Juices followed by excessive consumption of oxalate-rich juices appear to be a potential cause of oxalate nephropathy and acute renal failure. People at risk may be those who include foods rich in oxalate as part of an “aggressive juice program” and consume a large amount of that juice. One patient had acute oxalate-induced renal failure that was attributed to the consumption of fruit and vegetable juices rich in oxalate obtained from juices.
