So, the kidney stone diet includes reduced amounts of salt, animal proteins, sugary beverages, and (in some cases) high-oxalate food products like spinach, almonds, etc. At the same time, you need to drink plenty of water. But the detailed plan depends on the stone type, so urine and stone analysis make it much more precise.

The good news is that you don't have to give up food and start consuming just cucumbers. You just need to be aware of some of the unhealthy snacks that work against you.

What Food Should You Consume?

Stones appear when minerals like calcium, oxalate, and uric acid accumulate in concentrated urine, like sugar at the bottom of a chai glass. Diet plays an important role in determining how concentrated urine is.

The 2014 (updated in 2019) guideline of the American Urological Association recommends consuming enough fluids to produce 2.5 liters of urine per day and a diet that has a low sodium content. The prominent research conducted by Borghi et al. (New England Journal of Medicine, 2002) revealed that male patients with recurrent calcium stones whose diet had normal calcium intake, less salt, and animal protein had fewer recurrences than those whose diet was low in calcium. Thus, to avoid forming calcium stones, one should not skip dairy products.

Identifying problems early on

Before planning your meals, it is important to know the early symptoms of kidney stones. Such symptoms include dull pain in the back or side, waves of pain, painful urination, pink or cloudy urine, and nausea. If you ever experience fever along with severe pain, visit a doctor immediately and do not wait it out heroically.

Foods to Limit

  • Foods with high salt content: chips, pickles, papad, instant noodles. Sodium promotes the excretion of calcium in the urine.
  • Excessive intake of animal protein (red meat, organs, non-veg food) increases the levels of uric acid in urine and reduces the levels of citrate, your natural stone inhibitor.
  • Sugary drinks and colas: the study by Ferraro et al. (Clinical Journal of the American Society of Nephrology, 2013) shows the link between sugar-sweetened sodas and higher stone risk.
  • High-oxalate foods (in case of forming oxalate stones): spinach, beets, almonds, rhubarb, and chocolate. Do not avoid these foods completely.
  • High doses of vitamin C supplements: your body transforms a portion of it into oxalate.

Alternatives to the food

Regarding what to eat with kidney stones, think about citrus fruits, water, and the balance of your meals. Lemon water, oranges, melon, cucumber, curd, in combination with oxalate-rich meals and many vegetables, can help you with it. Remember that calcium from food will help to bind oxalate and therefore will be your best friend. Research performed at Harvard University shows that dietary calcium is connected with fewer occurrences of stones.
