However, this powerful elixir is not safe for everyone's consumption. Despite being rich in nutrients like antioxidants, which combat oxidative stress, and vitamins like vitamin C and several B vitamins, coconut water is not suitable, especially for those battling kidney disease. Why should you avoid coconut water with kidney disease? High in potassium According to experts, high potassium content in coconut water can lead to hyperkalaemia - a life-threatening issue. "The main concern lies in high potassium content. Kidneys play a vital role in filtering excess potassium from the blood. In individuals with chronic kidney disease, this function is impaired, leading to the risk of hyperkalaemia," Dr Kshitij Raghuvanshi, Urologist, Ruby Hall Clinic, told Times Now. Dr Raghuvanshi said even though mild hyperkalaemia can be asymptomatic, severe cases cause serious complications like abnormal heart rhythms, muscle weakness, or even paralysis. High in sodium Sodium - commonly known as salt - is an essential nutrient that plays a vital role in maintaining fluid balance, nerve and muscle function, and overall cellular health. However, too much of it is detrimental, as it leads to high blood pressure and fluid retention. "This can further strain the kidneys and worsen the progression of the disease," said Dr Raghuvanshi. A mild diuretic Coconut water also acts as a mild diuretic. For some kidney patients who already struggle with fluid balance and urine output, consuming it can cause electrolyte imbalances, dehydration, or unnecessary stress on the kidneys. "Additionally, those undergoing dialysis often need strict control of fluid intake, and beverages like coconut water can contribute to fluid overload," Dr Raghuvanshi added. Cannot replace electrolyte drinks Even though coconut water is packed with electrolytes, experts believe it may not provide enough for intense workouts or prolonged physical activities. There are many sports drinks that are designed for athletes and often contain higher levels of electrolytes like sodium, which are crucial for recovery after vigorous exercise. However, drinking coconut water can just make for a low-calorie substitute for gym-friendly drinks. It may also cause digestive issues and discomfort - including bloating or diarrhoea - due to its high fibre content or natural sugars. What should you drink for optimal kidney health? For healthy kidneys, it is important to stay hydrated with water, but certain other natural drinks can also offer benefits. A few of these include

• Pomegranate juice
• Green tea
• Plant-based milks like almond or oat milk
• Cranberry juice
• Lemon- or lime-infused water
