Yes, grapes can be a beneficial addition to the diet for those who have kidney stones. Grapes contain antioxidants and other compounds which can help reduce the risk of developing kidney stones. According to a 2004 report in the American Journal of Physiology – Kidney and Fluid Control Physiology, grapes are a good source of dietary fiber and antioxidants, which can reduce the levels of oxalate and uric acid in the body.
This is important because too much oxalate and uric acids can lead to kidney stones. Additionally, grapes contain high levels of potassium and magnesium, which are minerals that help regulate the pH balance in the body, allowing it to pass kidney stones more efficiently.
Furthermore, due to their diuretic properties, drinking grape juice can help flush out substances that can lead to the formation of kidney stones. Finally, since grapes contain citrate, one of the most effective stones inhibitors, scientists suggest that grapes could help prevent the formation of new stones from forming.

Are grapes high in oxalates?
Grapes are a good source of vitamins, minerals, and antioxidants. However, they do contain small amounts of oxalates. Oxalates are compounds found in some fruits and vegetables, and in high levels, can lead to conditions such as kidney stones.
So it is important to keep track of your intake of oxalates if you have a condition that is affected by oxalate consumption.
The amount of oxalates in grapes varies depending on the variety. White and green varieties, such as Thompson grapes and Concord grapes, have higher levels of oxalates than red varieties, such as Flame and Ruby seedless.
However, the levels are generally still quite low. A 100g serving of Flame Seedless grapes contains less than 1 milligram of oxalates, while a 100g serving of Thompson grapes contains between 1-2 milligrams.
Overall, grapes are generally a low-oxalate food, but it is important to monitor your intake if you have a condition that is affected by oxalates.
What fruits have no oxalates?
Meaning they contain a minimal amount of oxalates. Some examples of low-oxalate fruits include bananas, melons, pineapple, apples, peaches, plums, kiwi, strawberries, blueberries, raspberries, blackberries, watermelon, honeydew, cantaloupe, oranges, grapefruit, tangerines, lemons, limes, mangoes, papayas, and pears.
Additionally, many dried fruits such as raisins, dates, prunes, and apricots are also low in oxalates. Fruits can be a great source of vitamins, minerals, and dietary fiber, and can be helpful for those with diet restrictions due to the low-oxalate content.
Do grapes contain oxalic acid?
Yes, grapes contain small amounts of oxalic acid. Oxalic acid is a naturally occurring compound present in many different fruits and vegetables. Grapes contain around 0. 07 g of oxalic acid per 100 g of fresh fruit, depending on the grape variety.
This amount is much lower than other fruits and vegetables, such as rhubarb which contains around 0. 9 g of oxalic acid per 100 g.
Oxalic acid can cause health issues when consumed in large amounts, as it can bind with calcium to form calcium oxalate which can crystallize and cause kidney stones. For this reason, people with existing conditions such as gout and kidney stones should be cautious about consuming large quantities of grapes or other foods containing oxalic acid.
What foods neutralize oxalates?
Foods that generally help neutralize oxalates in the body include lemon juice, vinegar, spices, herbs, nuts and seeds, probiotics, activated charcoal, and foods high in insoluble fiber, such as fruits and vegetables.
Specific foods that have high levels of oxalate-neutralizing properties include apples, beets, Brussels sprouts, cherries, flaxseed, oranges, pineapples, peppers, potatoes, and tomatoes. Since oxalates are highly concentrated in some fruits and vegetables, it is important to choose low-oxalate varieties when possible.
Eating a balanced diet of low-oxalate fruits and vegetables, along with healthy sources of protein and fat, can help counter the effects of oxalates. Drinking plenty of fluids throughout the day can also help flush out excess oxalates.
Additionally, getting mild and regular exercise can improve digestion and help flush out oxalates.
What foods to avoid if you have kidney stones?
If you have kidney stones, you should avoid eating foods that are high in oxalate, a naturally occurring compound that is found in many foods. Examples of high-oxalate foods to avoid include spinach, rhubarb, beets, Swiss chard, sweet potatoes, nuts, berries, chocolate, tea, and wheat bran.
It’s also important to limit your intake of animal proteins such as red meat, pork, poultry and seafood, as well as dairy products. You should also avoid drinking excessive amounts of coffee or sugary beverages, as both of these can contribute to kidney stone formation.
Finally, it’s a good idea to limit your sodium intake, as this can also play a role in the development of kidney stones.
What are the 10 foods that cause kidney stones?
1. Oxalate-Rich Foods: Foods that are high in oxalate can contribute to the formation of calcium oxalate stones, the most common type of kidney stone. These foods include spinach, rhubarb, beets, sweet potatoes, nuts, chocolate, tea, wheat bran, and soy products.
2. Sodium-Rich Foods: Foods that are high in sodium, such as table salt, chips, processed meats, canned soups and frozen dinners, can contribute to the formation of calcium oxalate and uric acid kidney stones.
3. Animal Proteins: Too much dietary animal protein, such as beef, pork, poultry and fish, can cause an increase in uric acid and calcium levels in the urine, which can lead to urinary tract stones.
4. Alcohol: Heavy drinking is associated with an increased risk of kidney stones, especially if consumed on an empty stomach.
5. Calcium-Rich Foods: Consuming too much calcium in the form of dairy products, including milk, yogurt and cheese, can lead to calcium phosphate stones.
6. Caffeinated Beverages: Consuming more than four cups of coffee, tea, cola and energy drinks may increase the risk of kidney stones.
7. Fructose-Rich Foods and Beverages: Foods and beverages that are high in fructose, such as soda, juices, and baked goods, can increase your risk of uric acid stones.
8. Foods and Beverages Containing Artificial Sweeteners: Artificial sweeteners found in sugar-free candy, gum and soft drinks can lead to an increase in urine calcium and oxalate levels, which can contribute to the formation of kidney stones.
9. Vitamin C Supplements: Vitamin C supplements, specifically those taken in large doses, can increase the concentration of oxalate in the urine, leading to an increased risk of kidney stones.
10. Herbal Supplements: Herbal extracts, such as those taken from St. John’s wort and comfrey, can lead to an increase in oxalate levels in the kidney, increasing the risk of kidney stones.
Are grapes renal friendly?
Yes, grapes are considered renal-friendly because they are a low-potassium, low-sodium, and low-phosphorus fruit. Grapes contain a variety of vitamins, minerals, and antioxidants that can be beneficial for individuals with kidney disease.
Grapes are also a source of fiber and antioxidants, which may help slow the progression of chronic kidney disease and reduce complications. Additionally, grapes are relatively low in compounds such as potassium, phosphorus, and sodium, meaning they won’t significantly contribute to any electrolyte imbalances in those with kidney issues.
For these reasons, grapes may be beneficial for individuals with renal disease. However, it is important to discuss any dietary changes with your healthcare provider before incorporating grapes into your renal-friendly eating plan.
What do grapes do to kidneys?
Grapes have a number of beneficial effects on the kidneys. Grapes are rich in antioxidants, which can protect the kidneys from oxidative damage caused by free radicals. They also contain bioactive molecules like phenolic compounds, resveratrol, and ellagic acid that can protect the kidneys from oxidative damage.
Additionally, grapes are naturally low in sodium and are a good source of potassium, which can help reduce the risk of hypertension, a known risk factor for kidney health. Finally, grapes contain a wide variety of vitamins and minerals, such as vitamin C, B vitamins, magnesium, and copper, which can be beneficial to the kidneys.
Kidney function can be improved through the nutrients found in grapes, helping to keep the kidneys in top shape. Ultimately, grapes can be a helpful part of a diet that is supportive of kidney health.
