What are kidney stones?

Kidney stones are the hard deposits of minerals and acidic salts that get stuck together in concentrated urine. It can be very painful while passing through the urinary tract. However, kidney stones usually don’t cause permanent damage. Kidney stones are also called Nephrolithiasis.

There are several ways kidney stones are formed. Calcium may combine with certain chemicals such as oxalates or foods for us and form a solid hard mass.

Sometimes kidney stones can also be formed by a buildup of uric acid whereas uric acid build-up is caused by the metabolism of protein. And these hard masses are very difficult to pass. so obviously, it is a painful process.

  • Include vegetables rich in potassium to prevent kidney stones such as Brussels sprouts, Broccoli and kale.

It helps to decrease calcium loss from the body and prevents new kidney stones from forming.

  • Potassium rich vegetables also contain certain amounts of antioxidants that help prevent bladder and kidney cancer.
  • Add some more vegetables such as cauliflower, potato, carrots, green beans, tomatoes, cabbage and lettuce.
  • However, onions are low in potassium but they are a good source of chromium that helps us with carbohydrates, fat and protein metabolism.
  • Also opt for some dark leafy green vegetables as they are good sources of fibres and vitamin E along with other essential minerals.

  • Kolas should be highly avoided as these contain a large amount of sugar and phosphate and lead to the formation of kidney stones.
  • Chocolates are generally very high in sugar content and should be strictly avoided by the kidney patient. It also leads to weight gain.
  • Drinking less water leads to the accumulation of toxic materials in the body and does not get flushed out of it. So drinking more fluids specially water is very important to include in the diet chart to avoid kidney stones. The hydration levels in the body should be maintained throughout as the same person may get affected by this same problem again if reduces the amount of water intake.
  • Consuming too much protein is also bad for the kidneys health. you should restrict animal protein such as red meat, beef, chicken, egg and instead include some amounts of plant based protein sources.

Dietary risk factors for kidney stones

Kidney stones are also known as Nephrolithiasis. And has a high prevalence over the world. Also according to the latest studies, the cases of Nephrolithiasis are rising in both genders male and female of any age with an increasing rate every time.

Several dietary risk factors probably increase the chances of stone formation that including sodium, protein, potassium, calcium, magnesium, and other nutrients. These constituents may be modified according to the different kinds of kidney stones.

Especially the foods that produce acid rash after metabolism of the body may affect the lowering pH of urine whereas alkaline ash foods can increase the pH of urine that ultimately affecting the kidney stones. The dietary factors that stimulate the urine pH, urinary uric acid, and also types of stones risk kidney stones.

Some of the acid ash and alkaline ash foods stimulating factors are

Sodium

  • Dieticians recommend restricting sodium levels in the diet as sodium in the diet is capable of increasing the excretion of calcium and  potassium along with citrate from the body, resulting in an urinary pH change and eventually increases the risk of kidney stones.
  • A low sodium diet alone helps to minimize the loss of calcium and potassium from the body, and therefore helps to avoid inappropriate thiazides, mostly helpful in calcium oxalate stones.

Potassium

  • Potassium is available abundantly in several fruits and vegetables. You can opt for many different kinds of foods that are enriched in the nutrients potassium.
  • If a patient is having low urine site rate and low urine pH then potassium citrate should be included in the diet to further help hypothermia.
  • If a patient is suffering from chronic kidney disease as well and intakes antihypertensive medication, potassium levels should be monitored and regulated very carefully in this case.

Proteins

  • Patients suffering from acute or chronic infection usually have malnourished and experience catabolism and have been seen to contain more nitrogen in the urine.
  • Usually high ammonium and sulphate are the indicators of a rich protein diet. A high protein amount in the diet reduces urine pH, therefore, a moderate to low protein diet should be recommended( 0.8-1.4g/kg/d)

Calcium

  • Around 20% of calcium in the diet is absorbed under normal conditions. The evidence shows that a higher calcium diet is linked with lower kidney stone formation or probably Nephrolithiasis.
  • According to the studies, the people who consume a diet with normal calcium intake(1200mg/d)  have a 51% lower incidence of recurrent stones than the patients who consumed low calcium (400mg/d) diets.

Apart from these, some of the major dietary risk factors for kidney stones includes

  • Excessive protein in diet
  • Suffering from obesity
  • Including too much vitamin D than required.

Specific type for different kinds of stones.

Before making a diet chart, you must confirm with the doctor the type of kidney stone you have and accordingly plan your diet. As you might need to change what you eat or drink in different kinds of kidney stones.

The different kinds of kidney stones include

  • Calcium oxalate stones
  • Uric acid stones
  • Calcium phosphate stones
  • Cystine stones

Calcium oxalate stones

Reduce oxalates

  • If you are affected by calcium oxalate stones, you must avoid the following foods to reduce the amount of oxalate in urine.
  • Peanut, legumes.
  • Spinach
  • Wheat bran
  • Nuts and nuts products.

Limit animal protein

  • Adding more and more animal protein in your diet may increase your chances of developing stones.
  • You must limit some of the animal proteins such as beef, chicken, especially organ meats.
  • Eggs, fishes should also be limited in the diet.
  • Also limit milk, butter and other dairy products.

Uric acid stones

  • Uric acid stones demand to control your animal protein if you want to control its growth.
  • Limit animal protein sources such as beef, chicken, park, eggs, milk etc.
  • Instead of animal protein foods you may prefer some plant based foods typically high in protein such as soy foods, almonds, cashews, walnuts, sunflower seeds, beans, dried peas, lentils and peanuts.

Calcium phosphate stones

  • The chances of developing calcium phosphate stones increase when you intake more sodium. So try to limit the sodium content in your diet plan.
  • Limit animal protein foods
  • Add some plant based foods rich in protein.
  • Get enough calcium from organic foods rather than taking supplements such as fortified juices, cereals, bread, some kinds of vegetables and recommended beans.

Cystine stones

  • Drinking enough water in such kidney stones helps you a lot to prevent cystine stones and reduces its growth as well.
  • Along with water add liquid supplements such as juices and some detoxifying drinks.

How much liquid should I take if I have kidney stones?

  • We know that, the human body consists of 60 to 70% water and the kidneys well placed the role of filtering fluid out of blood and helps in flushing out the concentrated filtrate
  • The kidneys filter out about 180 litres of fluid each day. Out of these litres, an average healthy human produces about one to two litres of urine every day. Therefore it is recommended to drink at least two litres of water to compensate for this loss.
  • Staying hydrated is one of the key ways to stop the existing kidney stones from increasing in number. Drinking enough water helps to pass stone, which means that excess salt and minerals are flushed out from the body in the form of urine.
  • In addition, water also helps to move the stone, so that it travels through the urinary tract and eventually gets removed.
  • If you have kidney stones it is recommended that drinking about three to four litres that is 8 to 10 glasses of water every day helps to flush out the toxins from the body. But you can slightly increase the amount of water intake in this case.
  • Maintain an optimum amount of water intake in the diet. Must remember, do not drink a lot of water in an attempt to flush out kidney stones faster. However, the chances of drinking very high amounts of water is rare, but when it happens, it overworks the kidneys and prevents them from functioning optimally as it may dilute the sodium content and lead to adverse effects.

Along with water, the other hydrating fluids that you can opt for are

  • Fresh lemon soda
  • Coconut water
  • Fresh and unsweetened fruit juices
  • Vegetable juice
  • Cucumber and lemon detox drink
  • Watermelon mint juice

However, some drinks that you need to avoid for kidney stones are

  • Too much caffeine, that is tea and coffee.
  • Carbonated colas.

Diet in cystine stones

  • Cystine stones contain cysteine which is a product of amino acid cysteine and methionine and we all know that amino acids are the building blocks of protein. So the simplest way to limit cystine stones is to limit the protein intake.
  • Implementing certain dietary changes such as increasing the amount of water, limiting sodium intake and cutting down the alcohol amount helps you to prevent cysteine from forming and increasing in number.
  • Cut down the meat intake as it produces urine that has more acid that ultimately increases your risk for cystine stones.
  • Reduce the salt in your diet. Do not try to eat salty foods such as potato chips, French fries, sandwich meats, canned soups and packaged meals.
