There is a link between drinking soda and developing kidney stones, with one study finding that drinking one soda per day led to a 23% higher chance of kidney stone formation. While staying hydrated by drinking water is critical for preventing kidney stones, soda drinkers often do not drink enough water. In addition, sodas, especially colas, contain phosphoric acid, which is known to acidify urine and contribute to kidney stones. Citrus-based sodas, on the other hand, have higher levels of citrate, which can bind to calcium in the urinary tract and prevent stone formation. While the effectiveness of lemonade therapy is unclear, some doctors recommend it for preventing kidney stones.

Diet soda may help prevent kidney stones
While there is conflicting evidence on the link between soda and kidney stones, some studies suggest that diet soda may help prevent kidney stones.
Kidney stones are hardened deposits of salt and other minerals that do not properly filter through the kidneys. They can cause severe pain and may require surgery to remove. The main purpose of the urological system is to flush out toxins from the body, and this process depends heavily on hydration. Staying hydrated is critical for preventing kidney stones.
Soda is known to affect the urinary system, but it is not an effective hydrator. In fact, soda drinkers tend to be less hydrated overall. Dehydration is the most common cause of kidney stones. Therefore, while not a direct cause, soda can be a contributing factor to kidney stones.
However, not all types of soda are equally likely to contribute to kidney stone formation. Dark colas, artificial fruit punch, and sweet tea are the top drinks associated with kidney stones due to their high levels of fructose or phosphoric acid. On the other hand, citrus-based diet sodas, such as 7Up, Sprite, and Fresca, have been found to contain higher levels of citrate than even homemade lemonade, which is often recommended by doctors for preventing kidney stones. Citrate binds to calcium in the urinary tract, preventing stone formation.
While the effectiveness of "lemonade therapy" is still unclear, the higher citrate levels in certain diet sodas suggest that they may be beneficial in preventing kidney stones. More research is needed to confirm this potential benefit.

Soda consumption is linked to kidney stones
Kidney stones are hardened deposits of salt and other minerals that do not filter properly through the kidneys. The urological system's main function is to flush out toxins from the body, and this process is heavily dependent on hydration from water.
Secondly, sodas often contain high amounts of fructose or phosphoric acid, which are known to contribute to kidney stones. Phosphoric acid acidifies urine, and one study found that kidney stone patients who stopped drinking soda containing phosphoric acid decreased their chance of developing further kidney stones by 15%.
Thirdly, the high sugar content in soda can increase the risk of kidney stones. Sugar can cause an increase in calcium excretion, and calcium is a crystal-forming substance found in kidney stones.
However, it is important to note that not all sodas are equally capable of contributing to kidney stones. Citrus-based sodas, such as 7Up, Sprite, and Fresca, have been found to have higher citrate levels, which can prevent stone formation.
Overall, while soda consumption has been linked to kidney stones, more research is needed to fully understand the relationship between the two.

Phosphoric acid in soda may cause kidney stones
While there are no medications that can force kidney stones out of the body, drinking plenty of water can help to flush them out. However, it is important to note that not all fluids are equally beneficial for preventing kidney stones.
Soda has been linked to an increased risk of kidney stone formation. One study found that participants who drank one soda every day had a 23% higher chance of forming kidney stones. This is because soda contains high levels of fructose and phosphoric acid, which are known to contribute to kidney stones. Phosphoric acid is a common ingredient in soda, providing its tangy flavor. It has been found to lower the pH of urine, which can prevent struvite crystallization from occurring at all.
However, in the urinary tract of a healthy person, the decrease in urine pH may not be as high. In this case, the presence of a urinary stone, increased levels of phosphorus in the urine, and a urinary tract infection could influence the formation and growth of the stone. The surface of a urinary stone is usually porous, which favors the adhesion of bacteria, potentially causing the stone to build up faster.
Therefore, it is recommended to consume soda in moderation and opt for light citrus types that have less sugar and chemicals. If kidney stones run in your family, it is best to avoid soda altogether.

Citrus-based diet sodas have high citrate levels
Citrus-based sodas are known to have high citrate levels. Citric acid is a versatile additive used in food, beverages, medicines, and dietary supplements. It is also a useful disinfectant against bacteria and viruses. Citrate, a molecule closely related to citric acid, is the first molecule that forms during the citric acid cycle. These chemical reactions in the body help transform food into usable energy.
Citrus-based sodas have high citrate levels because they contain citric acid. Citric acid occurs naturally in citrus fruits, especially lemons and limes, and gives them their distinctive tart, sour taste. A manufactured form of citric acid is also commonly used as an additive in food and beverages. While natural citric acid is safe for consumption, the synthetic version is produced from black mold and can cause adverse reactions in some people.
Citrus-based sodas with high citrate levels can help prevent kidney stones. Citric acid is often used to treat kidney stones as potassium citrate. Consuming foods rich in this natural acid, like citrus fruits and juices, can offer similar kidney stone-preventing benefits. For instance, orange juice has been shown to reduce the risk of stone formation, while fresh-squeezed lemonade can also help prevent kidney stones. These beverages are high in citrate, which binds to calcium in the urinary tract, preventing stone formation.
While citrus-based sodas with high citrate levels can help prevent kidney stones, excessive consumption of soda can increase the risk of stone formation. This is because soda is never a viable alternative to water and is ineffective in hydrating the body. Therefore, while citrus-based sodas can be consumed in moderation, it is recommended to prioritize hydration by drinking lots of water to prevent kidney stones.

Lemonade therapy for kidney stones
While there is no medication that can force kidney stones out of the body, there are several natural remedies that can help with the pain and aid in passing the kidney stones. Lemonade therapy is one such natural remedy that can be used to treat kidney stones.
Lemonade therapy involves consuming lemonade to increase urinary citrate and urine volume, which can help prevent kidney stone formation. Citrate is a stone inhibitor that helps prevent new stones from forming and stops existing stones from growing in size. A study found that consuming 2 litres of regular or diet lemonade daily increased urine volume and urinary citrate, with diet lemonade resulting in a significant increase in urinary citrate from baseline.
To benefit from lemonade therapy, it is important to consume real lemon juice, either freshly squeezed or store-bought. Three ounces of lemon juice, or about six tablespoons, can be added to your daily diet. This amount can typically be squeezed from two medium-sized lemons.
It is important to note that acidic beverages like lemon juice can erode tooth enamel, so it is recommended to take steps to reduce their effects on teeth. Additionally, while hydration is key to preventing kidney stones, it is best to avoid soda, especially if kidney stones run in your family. Dark cola beverages, artificial fruit punch, and sweet tea are some of the top drinks that contribute to kidney stone formation due to their high fructose or phosphoric acid content.

Frequently asked questions
There is no clear answer to this question. While some studies suggest that diet sodas could be an effective weapon for some people prone to forming kidney stones, others indicate that not all sodas are equally capable of contributing to kidney stones. Dark colas, artificial fruit punch, and sweet tea are the top drinks that contribute to kidney stones.
Kidney stones develop when urine contains more crystal-forming substances such as calcium, uric acid, and oxalate than can be diluted by the available fluid. Most kidney stones are calcium-based, usually in combination with oxalate. The main symptoms of kidney stones include pain when urinating, nausea, frequent urination, fever, and cold chills.
It is recommended to drink lots of water and low-sugar beverages to prevent kidney stones. Water infused with citrus fruits like lemon, lime, and orange can also help break up the stones. Orange juice and fresh-squeezed lemonade are also great for preventing the formation of kidney stones as they are high in citrate, which binds to calcium in the urinary tract and prevents stone formation.
It is recommended to limit meat intake and look for low-sodium options when shopping for food. Eating diuretic foods like watermelon, celery, and cucumber may also help pass kidney stones.
