[Health Channel/Comprehensive Report] There are many "urban legends" about kidney stones, such as deliberately avoiding high-calcium foods, thinking that stones are calcium, and worrying about making the stones worse.
However, nutritionist Gao Minmin pointed out that sufficient calcium can reduce the intestinal absorption of oxalic acid and help reduce the occurrence of kidney stones.
She said that drinking enough water, eating enough calcium, avoiding high oxalic acid, high sodium and heavy salty diet, and not taking too much vitamin C can prevent or improve kidney stones.
Gao Minmin posted on the Facebook page "Gao Minmin Nutritionist" that kidney stones are a type of urinary tract stones, which refer to hard crystalline deposits formed by kidney metabolites in the urine, which will accumulate in the kidneys, and over time bigger.
She points out the types of kidney stones:
Please read on...
●Calcium oxalate stones:
the most common type, accounting for about 75%, showing white, gray, black and other dense stones.
●Phosphoric acid stones:
accounting for about 10-20%, the shape of this type is more irregular, mostly because of bacterial infection.
●Uric acid stones:
accounting for about 5%, they are orange-yellow transparent crystals, usually formed when uric acid in the body is too high.
●Others:
such as cystine stones, etc.
4 major ethnic groups at high risk of kidney stones
Gao Minmin explained that the following groups are high-risk groups for kidney stones:
●Insufficient water intake:
If there is no special disease, it is recommended to drink at least 1500-2000cc of water every day.
In addition, when the weather is hotter, you should increase the amount of water you drink.
●Obesity:
Obesity, such as increased body weight, BMI, and waist circumference, is closely related to kidney stones.
●Imbalanced diet:
Only eating a specific diet, or eating foods high in sodium, sugar, oxalate, and protein, can easily increase the chance of kidney stones.
●Family, personal medical history or other diseases:
If someone in the family suffers from kidney stones, the chances of other family members suffering from kidney stones are higher than the average person; other diseases may also cause kidney stones.
Diet 3 to prevent kidney stones
Gao Minmin suggested that you can eat in this way to prevent or improve kidney stones:
●Eat enough calcium:
1000mg per day is recommended. Sufficient calcium can reduce the absorption of oxalic acid in the human intestine and help reduce the recurrence of kidney stones. Many people worry that calcium oxalate will form in the body and reduce calcium supplementation, but daily intake is enough Calcium, in order to prevent or improve stone problems.
●Drink enough water:
2500cc per day is recommended. Excessive urination can dilute urinary calcium and oxalic acid precipitation and avoid excessive concentration.
Supplementing 2500cc of water per day can not only increase urine output, but also help metabolism.
●Appropriate amount of plant protein, reduce animal protein:
Eating too much animal protein can easily increase the urinary calcium concentration. It is recommended to replace part of the red meat intake with soy products or other high plant protein.
For example, black beans, soybeans, edamame, chickpeas, etc., are all very good vegetable proteins.
Diet 3 does not improve kidney stones
In addition, Gao Minmin said that the following foods should be avoided:
●High oxalic acid diet:
drink less strong tea, excessive coffee, and beverages, and supplement calcium between meals to reduce oxalic acid absorption and supplement calcium.
●High unit vitamin C:
Excessive vitamin C metabolism will form oxalic acid, increasing the risk of hyperoxaluria.
The recommended daily intake for adults is 100mg, and it should be mainly from natural sources. Excessive amounts will cause physical burden.
●High-sodium and heavy-salt diet:
Excessive sodium intake will be excreted in the urine, which may increase the concentration of urinary calcium and increase the precipitation and crystallization of stones.
Gao Minmin reminded that the above dietary principles are based on the example of calcium oxalate stones that many people will encounter. If it is like a crystallized stone caused by excessive uric acid, you can choose a "low Purine diet" to improve it.
It is the correct way to make adjustments based on the type of stones, and to identify the type through professional medical testing, and to prescribe the right medicine.
