Kidney stone patients should eat more foods with low purine content, because such foods can reduce the concentration of uric acid in the blood, and uric acid is related to the formation of kidney stones.

According to a report by the German Press Agency on the 20th, foods with low purine content include eggs, fruits, vegetables and dairy products. Kidney stone patients can also reduce the concentration of uric acid in the blood by drinking at least 3 liters of mineral water, diluted juice or tea every day.

The association pointed out that kidney stones are a sign of possible gout or chronic kidney disease. 40% of gout patients have suffered from kidney stones. People with kidney stones should consult a nephrologist about the type of stone they have. Stones containing uric acid crystals are at greater risk for chronic kidney damage.

In-depth exposition: What is 7?8 purine?

Organic compound, molecular formula C5H4N4, colorless crystal. Purine is oxidized in the human body and becomes uric acid. If the human body has too high uric acid, it will Causes gout. Commonly known as the disease of wealth. It usually occurs in men and is hereditary. Seafood and animal meat have relatively high purine content, so patients with gout are treated with drugs (drugs used to treat gout are generally harmful to the kidneys). ), more importantly, pay attention to dietary taboos in daily life.

There is a substance called purine in the human body, which mainly exists in the form of purine nucleotides and plays an important role in energy supply, metabolic regulation and coenzyme composition. plays a very important role. Gout can occur when its metabolism is disrupted.

Purine undergoes a series of metabolic changes, and the final product formed is called uric acid. Uric acid has no physiological function in the human body. Under normal circumstances, 2/3 of the uric acid produced in the body is excreted by the kidneys, and the remaining 1/3 is excreted from the intestines.

Uric acid is continuously produced and excreted in the body, so it maintains a certain concentration in the blood. The uric acid content per liter of blood for normal people is less than 0.42 mmol for men and no more than 0.0 for women. 357 mmol. During the synthesis and decomposition of purine, a variety of enzymes are involved. Due to congenital abnormalities of the enzyme or some unidentified factors, metabolism is disordered, resulting in increased synthesis or decreased excretion of uric acid, which can result in hyperuricemia. disease. When the blood uric acid concentration is too high, uric acid is deposited in the joints, soft tissues, cartilage and kidneys in the form of sodium salts, causing foreign body inflammatory reactions in the tissues and becoming the bane of gout.

1. Avoid eating high-purine foods: animal offal (liver, intestine, kidney, brain), seafood (abalone, crab, lobster, salmon, sardine) , tuna, carp, seabass, trout, cod), shell food, meat (beef, sheep, duck, goose, pigeon), soy food, lentils, spinach, broccoli, asparagus, mushrooms, soup, wheat Skin.

2. Stop eating high-cholesterol foods: animal offal (liver, intestine, kidney, brain), fatty meat, squid, fish, cuttlefish

3. Stop eating alcohol: do not drink alcohol , especially beer and Shaoxing wine. Once the blood alcohol concentration reaches 200mg/dl, the lactic acid in the blood will increase along with the oxidation process of ethanol, blocking the excretion of uric acid by the kidneys, resulting in an increase in uric acid in the blood.

4. Stop eating acidic foods, such as coffee, fried foods, and high-fat foods. An acid-base imbalance will affect body functions and increase the burden on the liver and kidneys.

5. Eat more high-potassium foods, such as bananas, broccoli, celery, etc. Potassium can reduce the precipitation of uric acid and help eliminate uric acid from the body. Eat enough alkaline foods, such as kelp, cabbage, celery, cucumbers, apples, tomatoes and other fruits.

6. Eat more foods that strengthen the kidneys. Traditional Chinese medicine believes that foods that strengthen the kidneys can help excrete uric acid. You can decoct the formula of "Liuwei Rehmannia" (rehmannia glutinosa, dogwood, yam, Alisma, paeonol, and poria) on weekdays to nourish yin and nourish the kidneys.

7. It is also suitable to eat more foods that promote qi, activate blood, and relax muscles and activate collaterals. For example, you can use locust (5 qian per person) to make sugar water, but instead of adding eggs, you can add lotus seeds.

8. Apple cider vinegar and honey. This is a traditional Western treatment method that has been proven effective by multiple clinical tests. Apple cider vinegar contains pectin, vitamins, minerals (phosphorus and potassium) and enzymes. The acidic component of apple cider vinegar has antiseptic properties and helps remove toxins from joints, blood vessels and organs. Drinking it regularly can regulate blood pressure, open blood vessels, lower cholesterol, and can also help treat arthritis and gout. After meals, add one teaspoon of apple cider vinegar and one teaspoon of honey to half a cup of warm water, mix well and drink.

9. Coix seed porridge for gout patients: take an appropriate amount of coix seed and white rice, the ratio of the two is about three to one. Soak the coix seed in water for four to five hours, and soak the white rice for 30 minutes. Then mix the two and add water to cook together to make porridge. Winter melon soup: Take 300 grams of winter melon (without the skin), five or six red dates, and a little shredded ginger. First sauté the shredded ginger in oil until fragrant, then put it into the pot along with sliced ??winter melon and red dates, add water and appropriate seasonings and cook it into soup.

10. Drink more water every day, go to the toilet more often, and never tolerate urination.
