Water, cranberry juice, lemon or lime juice and wine are drinks that help the kidneys, says Dr. Leslie Spry, contributor for The Huffington Post. These beverages aid the kidneys in filtering toxins from the blood and prevent kidney stones and bacterial infections.
Water is the best thing to drink for kidney health. It helps the kidneys filter toxins and waste from the blood and excrete them through the urine, notes Dr. Spry. Drink plenty of water to stay hydrated, especially during the summer months because dehydration and infrequent urination increase the chances of kidney stones.
Cranberry juice contains a compound that stops bacteria from sticking to the urinary tract wall and traveling up the ureter into the kidneys. Drinking a glass of cranberry juice each day might reduce the frequency of urinary tract infections that can turn into kidney infections, claims Dr. Spry. Lemon and lime citrus juices are also beneficial, as they contain high levels of citrate. Citrate may help prevent calcium from binding with minerals in the kidneys, creating crystals that form kidney stones. Citrate may also prevent crystals already present from connecting and creating larger stones.
Researchers determined that drinking less than one glass of wine per day may help keep the kidneys healthy and protect the heart in people with kidney disease, reports Dr. Spry. Individuals who drink less than one glass of wine each day have a significantly lower prevalence of chronic kidney disease than people who do not drink wine.
