A website visitor named Pierre from Paris France sent in the following question. He asked can drinking carrot juice cause kidney failure? No research thus far has shown that drinking any amount of carrot juice can cause kidney failure or kidney damage. Obviously toxic, rotten, or rancid carrot juice could potentially cause damage to the kidneys, however it would not be the carrot juice causing the damage, instead it would be caused by whatever bacteria or toxin happens to exist in the juice. Fresh homemade carrot juice has actually been shown to help improve overall kidney health and function, especially if consumed regularly. Carrot juice is very rich in alkaline minerals which can line the kidneys and help restore damaged tissues over the long term. A great kidney flush drink recipe is carrot juice mixed with lemon or lime juice, as this juice will help dissolve any kidney stones that the organs might contain. Many thanks to Pierre for the great question.
