5 superfoods to boost kidney health

Every year on the second Thursday of March, we celebrate World Kidney Day, a global initiative raising awareness about kidney health. Our kidneys are remarkable organs, silently filtering waste products from our blood, balancing electrolytes, and producing hormones vital for overall health. Yet, millions worldwide suffer from chronic kidney disease (CKD). According to a study published in the journal Kidney International Supplements in 2022, chronic kidney disease affects around 10 per cent of the population globally, amounting to almost 800 million individuals.

While there’s no single magic bullet for kidney health, incorporating certain superfoods into your diet can provide a powerful boost. Dr Prakash Chandra Shetty, a urologist at Dr LH Hiranandani Hospital, Powai, Mumbai and Dr Manju Aggarwal, chief- medical services & chairperson, Nephrology at Artemis Hospital Gurugram, listed 5 superfoods to boost kidney health.

Blueberries

Blueberries are rich in vitamins and minerals, containing antioxidants such as anthocyanins that reduce inflammation and protect against oxidative stress. These small berries are also low in sodium, potassium, and phosphorus, making them suitable for individuals with kidney issues. Including blueberries in your diet can help regulate blood pressure and prevent the development of kidney stones.

Salmon

A fatty fish abundant in omega-3 fatty acids, salmon possesses anti-inflammatory properties that promote a healthy cardiovascular system. Consuming fatty fish like salmon can lower cholesterol levels, thus reducing the risk of kidney disease. Additionally, salmon serves as an excellent protein source, providing essential amino acids vital for overall health and muscle function.

Regular consumption of garlic helps lower blood pressure, prevent heart diseases linked to elevated cholesterol levels, and protect the kidneys. Adding garlic to your meals not only enhances flavor but also provides an additional safeguard against kidney disease.

“If you have concerns about your kidney health, consult a healthcare professional,” Dr Shetty concludes.
