Sodium Foods

Sodium intake ups your risk of calcium oxalate and phosphate stones, which can make the kidneys excrete more calcium in the urine. The calcium combines with oxalate and phosphorus to form stones. Watch out for fast food, canned soups, packaged vegetables, pickled foods and processed meals for sodium. (Image source:Gettyimages)

High Oxalate Foods

When you have kidney stone(s), you need to limit the oxalate in your diet. Foods high in oxalate can increase oxalate level in the urine, which is harbinger for stone formation. Spinach, nuts, wheat bran and chocolate are some of the notable high-oxalate foods. (Image source:Gettyimages)

Vitamin C Foods

There is some scientific evidence that vitamin C or ascorbic acid supplements may increase the risk of stone formation for those who are at risk, and up complications for those with the condition. Make sure you are not eating peppers, green leafy veggies, guava, broccoli and other vitamin C foods in excess. (Image source:Gettyimages)

Foods High in Potassium

Kidney patients are advised to limit foods that are high in potassium, as these may lead to life-threatening complications such as heart failure. Tomato, potato, spinach, avocados, banana, orange and dried fruits should be limited. (Image source:Gettyimages)

Phosphorous Foods

Kidney conditions can cause excessive build-up of phosphorus in the blood which is harmful for the bones. High-phosphorus foods should be avoided; watch for foods such as chocolate, nuts, carbonated drinks and milk products. (Image source:Gettyimages)


Soda intake can increase the risk for kidney stones, associated with weight gain. You should also avoid sodas to help reduce recurrence of stones. Those with kidney stones must watch out for sodas, particularly those with phosphoric acid. (Image source:Gettyimages)

Caffeine and Alcohol

You need to limit caffeine and alcohol. Alcoholic and caffeinated beverages may initially increase urine output, but deplete your body of water. Moreover, caffeine can increase the amount of calcium in your urine. (Image source:Gettyimages)
