Besides a healthy lifestyle, choosing certain familiar foods daily can support more efficient kidney function and contribute to the body's ability to eliminate waste products.
When kidney function declines, the ability to filter and eliminate waste products is affected, leading to numerous health consequences. According to the World Health Organization, approximately 674 million people worldwide suffer from chronic kidney disease. Besides medical interventions and a healthy lifestyle, choosing certain foods can support more efficient kidney function over time.
Here are 5 foods that are good for kidney health:
1. Winter melon (green squash) is good for the kidneys.
Winter melon has a high water content, which helps replenish fluids in the body, thereby supporting the kidneys in the filtration and excretion process. This food also has a mild diuretic effect, helping to increase urine output, contributing to reducing the risk of kidney stone formation and urinary tract infections.
Additionally, winter melon provides potassium – a mineral essential for maintaining electrolyte balance, beneficial for people with normal kidney function. However, people with chronic kidney disease need to control their consumption to avoid electrolyte imbalances. Winter melon can be consumed in the form of soup or juice, and is especially suitable for those prone to dehydration.
Winter melon juice provides water and potassium, which helps the kidneys filter toxins.
2. Garlic contains important compounds that help the kidneys filter toxins.
Garlic is a familiar food that can support kidney function when used appropriately. Thanks to its sulfur compounds, especially allicin, garlic has anti-inflammatory and antioxidant properties, helping to protect kidney cells from the effects of oxidative stress and inflammation.
In addition, garlic helps control blood pressure and cholesterol – two factors that can put strain on the kidneys if they remain high for an extended period. Garlic is also considered a food that indirectly supports detoxification by promoting liver function, thereby reducing the metabolic burden on the kidneys. Thanks to its natural antibacterial properties, garlic can also contribute to reducing the risk of urinary tract infections, a condition that, if prolonged, can affect kidney health.
Raw garlic offers the highest concentration of active compounds; however, lightly cooked garlic in soups, stir-fries, or curries retains many of its benefits. For people with chronic kidney disease, garlic is a low-potassium spice that can be used to enhance the flavor of dishes and reduce the need for salt – a factor detrimental to kidney function.
Adding garlic to your daily diet in moderation, such as one clove, may support circulation and kidney function. However, those taking anticoagulants or blood thinners should consult their doctor before significantly increasing their garlic intake, as garlic has a mild anticoagulant effect.
3. Apples are rich in fiber.
Apples are one of the best fruits for kidney health because they are rich in soluble fiber (pectin), which binds to cholesterol and toxins, reducing the burden on the kidneys during detoxification. Apples are naturally low in potassium, making them safe even for patients with chronic kidney disease (CKD).
The antioxidants in apples, particularly quercetin, help reduce inflammation and oxidative stress, protecting kidney cells from damage. Apples also regulate blood sugar levels, which is crucial since uncontrolled diabetes is a leading cause of kidney failure.
Soluble fiber aids digestion and reduces urea (a waste product in the blood) toxins that can build up when the kidneys are weakened. Raw apples, sliced apples, or unsweetened applesauce are all beneficial for kidney health. In addition, packaged apple juice should be avoided as it often contains added sugar, putting a strain on the kidneys.
Eating a medium-sized apple a day can help with gentle detoxification, lower cholesterol, and support a healthy filtration rate. Combined with a balanced diet, apples contribute to long-term kidney protection by promoting cardiovascular health and naturally regulating fluid balance.
4. Coriander seeds are diuretics that support kidney health.
Coriander seeds have a cooling effect, are a mild diuretic, and are excellent for eliminating toxins through the urinary tract. They support kidney health, helping the kidneys filter toxins by removing waste and excess acid. The abundant antioxidants in coriander seeds protect liver cells from damage, support digestion, and promote healthy metabolism, all contributing to gentle daily detoxification. Additionally, coriander seeds support urine production and help the body excrete excess sodium. This reduces water retention and lessens the burden on the kidneys.
A simple way to incorporate coriander seeds into your daily routine is to use coriander seed water. You can do this by soaking 1-2 teaspoons of coriander seeds overnight, boiling them in water in the morning, and sipping the warm mixture throughout the day to soothe the digestive system, improve skin, and support hormonal balance.
Coriander seeds support urine production, reduce water retention, and lessen the burden on the kidneys.
5. Cauliflower reduces the burden on the kidneys.
Cauliflower is a cruciferous vegetable that benefits kidney health due to its naturally low levels of potassium and phosphorus – two minerals that often need to be limited in people with kidney disease. In addition, cauliflower is rich in vitamin C, folate, and fiber, which helps fight inflammation, improve digestion, and indirectly reduce the metabolic burden on the kidneys. This vegetable also contains bioactive compounds such as indole and glucosinolate, which play a role in supporting the body's detoxification process by neutralizing harmful substances.
Cauliflower is a versatile food that can be boiled, steamed, baked, pureed to replace potatoes, or used in soups. For people with chronic kidney disease (CKD), replacing starchy and potassium-rich foods like potatoes with cauliflower may help limit water retention and reduce the risk of electrolyte imbalance.
Additionally, cauliflower has a mild diuretic effect, contributing to maintaining fluid balance in the body and supporting kidney function. The antioxidants in this vegetable help protect kidney tissue from oxidative stress, thereby slowing the risk of progression of chronic kidney disease. Consuming cauliflower a few times a week can support metabolic health, help control blood sugar and weight – important factors in reducing the burden on the kidneys and maintaining stable filtering function.
