If you have kidney calculi's disease, please ask your doctor what kind of stones you belong to. This will help you know which foods should be avoided.
But if you are not sure, or just want to prevent all kinds of kidney calculi, a general suggestion is to stay away from salty food, meat and other animal proteins.
Remember to drink plenty of water. Water will help dilute the waste in urine, making it more difficult to form stones. During the period of paying attention to diet, you can drink jade tea for a long time, pure plants, safe and without side effects.
First, calcium oxalate stones
Calcium oxalate stones are more common than other types of stones. Calcium in urine will form stones when combined with oxalate, which is a natural chemical in many foods.
If you have calcium oxalate stones, please be careful to eat high oxalate food. Many plants contain oxalate, which is difficult to avoid completely.
However, the content of some foods is much higher than others, which should be avoided as much as possible:
(1) spinach
(2) Rhubarb
(3) Almonds and cashews
(4) Miso soup
(5) Coarse corn flour
(6) Baked potatoes with skins
(7) Beet
(8) Cocoa powder
(9) Okra
(10) bran cereals and broken cereals
(1 1) French fries
(12) raspberry
(13) Stevia Sweetener
(14) sweet potato
A mixture of oxalate and calcium
If you eat food or drink rich in calcium at the same time, it can help your body deal with oxalate, thus reducing the formation of kidney calculi. So spinach salad can be eaten with low-fat cheese, or nuts and berries can be eaten with yogurt. Pay attention that milk will not cause kidney calculi.
2. salt
Intake of a large amount of sodium (salt component) will increase the calcium content in urine. After eating, any excess oxalate will "stick" to the calcium in the kidney, thus forming stones. Therefore, the consumption of canned food, packaged meat, fast food and condiments should be restricted.
3. Animal protein
Restrict the consumption of beef, pork, eggs, cheese and fish; These foods may increase the incidence of most kidney calculi.
4. vitamin c
Too much vitamin C can cause the body to produce oxalate. Therefore, the daily intake should not exceed 500 mg.
Second, calcium phosphate stones.
Calcium phosphate stones are formed when calcium in urine combines with mineral phosphorus. Patients with calcium phosphate stones need not worry about oxalate. But pay attention to:
Foods rich in animal protein:
(1) internal organs, such as chicken liver or bovine liver.
(2) Milk, cheese and other dairy products
(3) eggs
(4) seafood
Foods that aggravate urine alkalinity include:
(1) Fresh juice (except oranges, cranberries and nectarines).
(2) vegetable juice.
(3) syrup.
(4) Processed food: Phosphorus is a common additive and preservative. So fast food, bottled coke, frozen food and lunch meat should be restricted. Read the ingredients that start with "phosphorus" in the label.
Sodium: Most Americans eat too much sodium. The goal is not to exceed 1 teaspoon of salt per day.
Third, uric acid stones
Excessive uric acid can lead to uric acid stones. Uric acid stones contain uric acid, which is produced when the human body decomposes chemicals in food. Unlike calcium oxalate and calcium phosphate stones, sodium has no special effect here.
Animal protein: Eating too much red meat, poultry, eggs and shellfish will have two effects.
Make the body produce more uric acid;
Leading to the failure of citrate system. Citrate can help prevent kidney calculi and prevent the existing kidney calculi from getting bigger.
In order to get enough protein, the following foods can be used instead of meat and poultry:
(1) beans, dried peas, lentils and peanuts.
(2) Soybean milk, soybean milk and tofu.
(3) Nuts, such as almonds, walnuts and cashews.
(4) Sugary drinks: Lemonade, lime juice, fruit juice and other acidic drinks have high citric acid content, which helps to prevent kidney calculi. But don't eat foods and drinks flavored with sugar, especially high fructose corn syrup. Foods and drinks with high sugar content can lead to stones.
(5) Alcohol: Alcohol will lead to the increase of uric acid level in blood.
Fourth, cystine stones.
Cystine stones are caused by genetic causes. Let a natural substance called cysteine enter the urine. Cystine stones are usually larger than other types of stones. If you have had cystine stones once, you will probably have a second time.
Questions you need to pay attention to:
1. Drink too little water: Drinking more water can help prevent cystine from forming stones.
2. Too much acid: Cystine stones are more likely to grow in acidic urine, which is contrary to calcium phosphate stones that are more inclined to alkaline urine. Therefore, for this kind of stone, we should eat less meat and eat more fruits and vegetables with lower acid content.
3. Sodium: Again, don't overeat foods with high salt content such as French fries, canned soup and packaged meat.
