Five Superfoods To Improve Kidney Function

Although there isn’t a single panacea for kidney health, adding some superfoods to your diet can have a significant positive impact. Five superfoods that improve kidney health were identified by Dr. Manju Aggarwal, chief medical services officer and chairperson of nephrology at Artemis Hospital in Gurugram, and Dr. Prakash Chandra Shetty, urologist at Dr. LH Hiranandani Hospital in Powai, Mumbai.


Anthocyanins, an antioxidant found in blueberries that lower inflammation and guard against oxidative stress, are among the many vitamins and minerals that these berries contain. These little berries are good for people with kidney problems since they are low in potassium, salt, and phosphorus. Consuming blueberries can help control blood pressure and stave off kidney stones from forming.


Salmon, a fatty fish high in omega-3 fatty acids, has anti-inflammatory qualities that support a strong cardiovascular system. Eating fish high in fat, such as salmon, helps decrease cholesterol and lower the risk of kidney disease. Salmon is also a great source of protein since it contains important amino acids that are necessary for both muscle and general health.


Unmatched in terms of nutrition, kale is a powerhouse of vitamins, minerals, and antioxidants—especially vitamin K, which is essential for healthy blood coagulation and strong bones. Kale is a good option for people with kidney illness who need to restrict their potassium consumption because of its low potassium concentration. Including kale in your diet on a regular basis can assist maintain kidney function and improve your general health.


Allicin, found in garlic, has been known for its antibacterial and anti-inflammatory qualities for decades. Garlic reduces blood pressure, prevents heart attacks associated with high cholesterol, and safeguards the kidneys when taken regularly. Garlic not only adds flavour to food but also offers an extra layer of protection against kidney disease.


Quinoa is a whole grain that is free of gluten and high in key minerals like iron, magnesium, fibre, protein, and iron. Quinoa is low in potassium and phosphorus, which makes it a good substitute for people with kidney problems, unlike many other cereals. Its high fibre content supports healthy digestion and aids in blood sugar stabilisation. Switching from other carbohydrates to quinoa as your main source of energy can have a big impact on renal function.

In addition to these superfoods, Dr. Shetty discusses how hydration can enhance kidney function. ““Water is essential for flushing toxins and waste products out of your kidneys, so aim for at least eight glasses of water daily, based on your activity level and climate.”  To keep kidneys in good condition, he also suggests cutting out on processed meals, refined carbohydrates, and high sodium intake.
