Doctors Warn About Foods That Can Cause Kidney Stones If Consumed in Excess
A man with the surname Tran (from China) was recently hospitalized due to his habit of eating too much red meat. His friend, Ms. Wang, shared that Mr. Tran loves beef and consumes it daily. Despite warnings from friends to limit his intake, he believed his health was fine after many years of such a diet.
One day, he suddenly experienced severe abdominal pain that caused him to faint, requiring his family to take him to the hospital. After examination, doctors found that he had kidney stones and needed immediate treatment. The doctor stated: “I reviewed your dietary history, and you consume too much red meat. These foods are a contributing factor to the formation of stones.” At that moment, Mr. Tran reflected on his friends’ warnings and regretted his unbalanced diet.
Excessive consumption of animal protein, such as red meat, poultry, eggs, and seafood, raises uric acid levels and can lead to kidney stones. A high-protein diet also reduces citrate levels in urine, a chemical that helps prevent stone formation.
Kidney stones are deposits of substances that should dissolve in urine but crystallize and form stones for various reasons. The size of the stones varies depending on the time, location, and deposition characteristics.
If left untreated, kidney stones can cause painful urination, blood in urine, frequent urination, back pain, urinary tract infections, etc. To prevent this, experts recommend establishing a balanced diet and lifestyle, avoiding the mistakes outlined below when eating.
The size of kidney stones varies depending on the time, location, and deposition characteristics.
Dr. Peng Liyu (Treating Physician, Department of Nutrition, Central Hospital of Zhuzhou, China) shares insights about foods that stimulate kidney stone formation.
1. Spinach
Spinach is a nutritious vegetable but also contains a high amount of oxalic acid. Excessive consumption can lead to the formation of calcium oxalate with calcium ions, ultimately resulting in stones.
Correct consumption method: While spinach can increase the risk of stone formation, this does not mean you should avoid it entirely. It is advisable to blanch the spinach in boiling water before cooking. Patients with gout or kidney issues should consult a doctor before consumption. Those who have recently undergone surgery should also avoid this vegetable.
2. Calcium-rich foods
Calcium is essential for the body, especially for bones and joints. However, excessive calcium can overload the kidneys, increasing the risk of ureteral stones and kidney stones.
In addition to dietary sources, calcium supplements taken during meals can also heighten the risk. Nonetheless, healthy individuals should not excessively avoid calcium-containing foods, as this could lead to imbalances in calcium absorption and increase the risk of osteoporosis.
Correct consumption method: Consume calcium-rich foods in moderation or consult a doctor.
3. Sodium-rich foods
Sodium increases calcium levels in urine, raising the risk of stone formation.
Correct consumption method: Reduce the intake of processed foods and pickled items… and increase water intake to prevent kidney stones.
4. Sugar and refined starches
These foods lack essential fiber, leading to increased blood sugar levels. Excessive consumption can greatly elevate the risk of kidney stones and diabetes.
Correct consumption method: Reduce sugary foods and instead increase the intake of naturally sweet fruits and vegetables.
5. Fried foods
Excessive consumption of fried foods is one of the main causes of kidney stones. These foods often contain high levels of saturated fats, which increase bad cholesterol in the blood, leading to a higher likelihood of stones.
Correct consumption method: To limit or avoid foods high in cholesterol, reduce intake of items such as fatty meats, organ meats, fish eggs, crab roe, and egg yolks… Instead, focus on consuming more fresh fruits and vegetables and some foods that help lower cholesterol, such as garlic, onions, shiitake mushrooms, and black fungus…
What Should You Eat to Prevent Kidney Stones?
- Protein: Prioritize plant-based proteins such as beans, sprouts, or fish instead of proteins from meat, eggs, and dairy…
- Fiber: Aim to consume 7-10 servings of fruits and vegetables daily to prevent constipation, diarrhea, and slow fat absorption after meals.
- Healthy fats: Moderate amounts of healthy fats found in sunflower oil, olive oil, canola oil, avocados, cashews, and walnuts help maintain kidney health.
