Foods that support Kidney Health
Foods suitable for the kidneys should contain essential antioxidants and several vitamins and minerals, but they also contain minimal sodium, potassium, and phosphorus. A balanced diet combined with these foods will help the kidney function, manage inflammation, and avoid kidney-related complications.
Below is a list of ten foods that have proven benefits to the kidneys.
1. Berries (Blueberries, Strawberries, Raspberries, Cranberries)
Blueberries, strawberries, raspberries, and cranberries may benefit the kidneys because of their potent antioxidants. Antioxidants have the potential to influence oxidative stress and inflammation, which are known to damage the kidneys.[1]
Moreover, these berries are relatively low in potassium, phosphorus, and sodium. Berries are also a great source of fibre, which enhances digestion and overall health. Therefore, berries can be consumed without worry, especially by those with dietary restrictions.
Blueberries are a good source of vitamin C, vitamin K, and fibre.[2] Cherries and blackberries are said to manage inflammation, which logically helps the kidneys.[3] Cranberries are also suitable for urinary tract health.[4] [5]
You can enjoy berries as it is or integrate them into a smoothie, or garnish with oatmeal and yoghurt. They are delicious treats that are also good for the kidneys. Including these berries in your daily meals might offer the best support for the kidneys.
You might be worried about striking a balance between eating nutritious meals and your dietary fibre consumption. For you, meal planning can be a more complicated matter, and you might be searching for strategies to deal with it.
Aashirvaad Atta Multigrains created the My Meal Plan test. The test calculates your daily fibre intake to make a meal plan that meets your needs.
2. Barley May Support Kidney Health
Barley benefits kidney health by managing kidney stone formation and supporting proper kidney operation. Its nutritional components, including fibre and minerals, together with its natural diuretic qualities, enable the kidneys to function better.
Drinking barley water preserves a regular urine pH to manage kidney stones from developing. The fluid excretion process includes waste products such as calcium, which may help control the risk of calcium oxalate stone formation. [6]
Barley fibre may protect kidney health by preventing calcium urine excretion. Barley contains magnesium, a mineral that breaks down calcium oxalate crystals that normally form kidney stones.
After boiling barley in water, you can consume it as a hot beverage, enhancing the nutritional value of soups and salads.
3. Garlic
Garlic has powerful antioxidant and anti-inflammatory effects that may positively impact a kidney-friendly diet. Some of its main constituents, such as allicin, alliin, and ajoene, may help manage damaging oxidants and inflammation that harm the kidneys.[7]
Its influence on the cardiovascular health gut microbiome may be beneficial for kidney health.[8] [9]For those on a low-salt diet, garlic adds zest while promoting health, which may make it ideal for those requiring sodium restriction.
To make your dishes more enjoyable, you can easily add garlic, in powder or fresh form, to your meals, use it in ‘olive oil garlic bread,’ or stir-fry it with herbs and onions.
4. Olive Oil May Support Kidney Health
Extra virgin olive oil, especially oleic acid, can be beneficial in a kidney-friendly diet. Its monounsaturated fats may reduce “bad” cholesterol and improve heart health. [10]
Apart from these fats, olive oil also contains polyphenols, which, along with oleic acid, might be strongly anti-inflammatory. These might help manage inflammation of the kidneys and cardiovascular system, improving overall health.[11]
Olive oil consumption in the Mediterranean diet is associated with better kidney and cardiovascular health.[12] Due to its lack of phosphorus and low potassium, olive oil sauces and seasonings may improve kidney function and aid in the tastiness of food while
5. Apples
Apples may be an exceptional choice for a kidney-friendly diet because they contain low levels of potassium, phosphorus, and sodium. This may be especially beneficial for people with kidney disease or those undergoing kidney surgery dialysis. [13]
As previously noted, apples have very low mineral levels, which are cumbersome for the kidneys to process. [14] However, apples, being a fibrous food, may help the kidneys operate adequately because they may help regulate cholesterol and aid proper digestion.
Apples’ inflammatory effects may aid kidney functions, such as inflammation and oxidative damage. Furthermore, apple fluid and low calcium content may manage the risk of developing renal stones. [15]
Vitamin C boosts immunity, thus providing value to the kidneys. You can add apples’ stewed, baked, and sauced varieties to the list, along with apple juice and cider, making them easier to eat every day.
6. Peas May Support Kidney Health
Peas’ protein content is an important plant-based source of support for kidney health. Their nutritional value includes essential elements like fibre, iron, and potassium, which makes them an advantageous food for balanced meals.
Peas may be a positive food choice for kidney health because they have reduced phosphorus content. [16] Individuals with kidney problems may consume peas as they are low in phosphorous since their kidneys may face difficulties processing phosphorus, thus creating body chemical imbalances.[17]
People with non-dialysis chronic kidney disease (CKD) should choose peas as their protein source. People with kidney dysfunction must control their potassium and phosphorus consumption because these substances might accumulate in the bloodstream. [18] [19]
You can easily add beans to your meals through soup, stew, salad, or puree and spread preparations.
7. Fatty Fish May Support Kidney Health
Fatty fish, such as salmon and sardines, may be beneficial to kidney health due to their rich omega-3 fat content and low phosphorus & potassium content. [20] Omega-3s foster proper kidney function and manage inflammation, controlling the effects of disease. [21]
Additionally, omega-3 fatty acids may manage blood pressure and the risk of heart disease, which is essential for renal health.[22] Therefore, fatty fish consumption may contribute to cardiovascular and renal health simultaneously, albeit indirectly.
Depending on your choice and the type of fish, you can eat fish in numerous ways, including cooked, baked, fried, grilled, poached, or steamed.
8. Cucumbers May Support Kidney Health
Cucumbers support kidney health because their high water content may aid hydration, which is necessary for proper blood filtration and detoxification.[23]
Although cucumbers are low in potassium, this miracle food may help maintain overall electrolyte balance, which is crucial for kidney function. Moreover, the citric acid naturally contained in cucumbers may help manage kidney stones while promoting adequate hydration and improving kidney function.[24]
Cucumbers are ideal for those on restricted diets due to their flexibility. They can be eaten fresh in salads, soups, or even as a standalone snack.
9. Cabbage
Cabbage has a low content of elements like sodium, phosphorus, potassium, and magnesium. This is advantageous for people with chronic kidney ailments and for those who wish to keep their kidneys healthy. [25] [26]
Cabbage is a rich source of antioxidants, vitamins C and K, which may manage cellular and tissue breakdown. Furthermore, it is high in fibre, which may fight inflammation and aid healthy digestion, constipation, and kidney issues.
This superfood’s low content of oxalate may make it one of the best foods for people suffering from kidney stones. Some research suggests that cabbage may manage some toxins’ damaging effects on the kidneys. [27]
It is better to consume it in cooked form. as boiling helps leach out excess potassium from the vegetables, which is essential for individuals with any kidney ailments. Cabbage can be consumed steamed or boiled, served as a main dish, added to soups, or used as an essential ingredient in stuffed cabbage and cabbage rolls. These are wholesome meals.
10. Lemons May Support Kidney Health
Lemons may be part of a kidney-friendly diet. They may help manage kidney stones by detoxifying calcium and raising the calcium–citrate balance of urine, which increases the calcium-citrate ratio of urine.
The citric acid in lemons may manage the formation of renal stones by inhibiting the formation of calcite crystals. [28]
Drinking lemon juice is suggested to keep urine citrate concentration high, which diminishes the likelihood of kidney stones. [29] The National Kidney Foundation suggests concentrating half a cup of lemon juice and dissolving it in water daily to manage stone formation. [30]
The use of lemon water as a refreshing drink is known to enhance relaxation and comfort while supporting hydration. This is important for the kidneys as hydration helps with the elimination of wastes and toxins from the body.
Moreover, lemons are as potent as Vitamin C, a kidney defender against cell damage. [31] Because they are low in potassium, they are deemed safe for the dietary needs of people with kidney disease.
