Daily habits that cause kidney stones – VnExpress

Kidney stones can be completely prevented by changing harmful habits such as eating a lot of salt, lots of animal protein, drinking less water…

Kidney stones are hard deposits of minerals and salts that form in the urinary tract. Urine contains various waste products, including calcium, oxalate, and uric acid. Normally, they will escape from the body when urinating. If the urine is too concentrated, meaning there isn’t enough liquid to dilute the waste products, they stay in the body and crystallize, forming kidney stones.

Kidney stones can occur at any age, but they are most common in the 30s and older. Although age increases the risk of kidney stones, eating and living habits also play a big role.

Eat a lot of sugar and salt

Besides causing weight gain, the diet is also involved in the intake of substances that directly form kidney stones. The main culprits include fructose (also known as fruit sugar) found in white sugar, and salt, which increases calcium levels in the kidneys.

To reduce salt intake, limit certain foods including: processed meats such as ham, sausages and bacon, salted snacks, salad dressings, mustard, ketchup, water soy sauce, barbecue sauce, pickles, prepared foods…

Eat lots of animal protein

Red meat, poultry, eggs, dairy and seafood can increase uric acid levels, leading to stone formation. Reduce animal protein and increase plant protein from nuts, seeds like almonds, legumes like peanuts or lentils, soy products including soy milk or tofu.

Eat foods rich in oxalates

It’s not just unhealthy foods that cause problems. Oxalates, organic compounds found in many fruits, vegetables, and nuts, can also cause kidney stones.

Foods rich in oxalates may increase the risk of calcium oxalate stone formation. Calcium Oxalate accounts for a high percentage in tropical countries like Vietnam. This stone is very hard and opaque, has a rough appearance, yellow or brown in color.

Some foods high in oxalates include: spinach, turnips, okra, raspberries, dates, avocados, rice bran, soybean meal, brown rice flour, millet, barley flour, cornmeal , soybeans, cocoa powder, hot chocolate, miso soup, baked potatoes, french fries, grains such as shredded wheat and raisin bran…

Drink some water

Many people get kidney stones simply because they don’t drink enough water. Water helps to remove excess minerals from the body. Minerals can build up in the kidneys, forming kidney stones, if you don’t drink enough water.

Experts recommend that each person should drink at least 2 liters of fluid per day. People with cystine stones may need to drink more than 2 liters.

If the body is sufficiently hydrated, the urine will be light yellow or clear. If you’re participating in intense workouts or working out in the hot sun, make sure you stay hydrated.

Incorrect calcium and vitamin supplements

Too much or too little calcium can lead to kidney stones. It is best to get calcium through the diet. Calcium can be found in juices, cereals or breads, some vegetables especially green ones like kale or spinach, soybeans, dairy products, etc.

Calcium supplements may be helpful for people with low calcium levels. However, taking too many supplements can also cause problems. Talk to your doctor about the vitamins you’re taking. Excess vitamin C or D can also increase the risk of stone formation.


Research shows that obese people are more prone to kidney stones. So, lose weight or stay at a healthy weight to reduce the risk of kidney stones.

Kidney stones are a common disease, common in daily life. Although this is a dangerous disease, it is not difficult to cure. Everyone can actively prevent and diagnose kidney stones early by taking care of their health, maintaining a healthy lifestyle and having a hygienic and scientific diet.
