Social media is often flooded with unconfirmed information on different topics, the latest being the health benefits of barley seeds. In a recent viral video, it was claimed that barley water can reduce creatinine levels to save kidneys and even potentially reverse chronic kidney disease. “I beg to differ as a nephrologist in the field for over 40 years,” responded Dr Sundar Sankaran, program director, Aster Institute of Renal Transplantation, Aster Hospital, Bangalore, on his social media handle.
Dr Sankaran explains that as the search for dietary interventions to manage or reverse chronic kidney disease (CKD) continues, the spotlight often falls on natural remedies, one of which is barley. “…Saying barley seeds are the magic prevention and treatment is stupid. There is no scientific evidence for such claims. I wish and pray we have simple remedies for CKD,” Dr Sankaran added in his response to the video.
Speaking to Happiest Health, Dr Sankaran reiterated that barley water does not have the power to reverse chronic kidney disease. “It is just another myth waiting to be debunked,” he said. “Barley is not a magical cure for kidney failure. If someone undergoing dialysis stops it and starts consuming barley water instead, it can be life-threatening,” he cautioned. He also shared that a person undergoing dialysis should not drink more than half a liter of fluid per day.
When is barley water considered beneficial?
“Barley is a whole grain known for its nutritional benefits, including fiber, vitamins and minerals. It helps with blood sugar control and can improve heart health,” says Dr Sankaran. He adds that the grain’s low glycemic index and ability to aid hydration and increase urine output make it a beneficial addition to a balanced diet. “It can help prevent kidney stones, as hydration always helps. Barley and barley water can also support general health by promoting hydration. Besides, it potentially aids in the management of blood pressure and sugar levels,” he adds.
Does barley water help reverse CKD?
The kidneys are vital organs responsible for filtering wastes and excess fluids from the blood, which are then excreted through urine. In people with chronic kidney disease, there is a gradual loss of kidney function over time.
Dr Avinash Ignatius, senior consultant nephrologist and transplant physician, Ruby Hall Clinic, Pune, Maharashtra, also agrees with Dr Sankaran and adds that there is no research proving that barley water can reverse CKD. “When CKD occurs, the kidneys’ filtering process becomes inefficient, leading to the dangerous buildup of waste materials in the body. Symptoms such as fatigue, swelling and changes in urine output can emerge. These can significantly impacting the quality of life,” says Dr Ignatius.
CKD is often a result of underlying conditions like diabetes and high blood pressure, say experts. This makes its management a multifaceted challenge. Further, the condition can significantly alter the course of a person’s life, as it requires rigorous treatment regimes, including dialysis or kidney transplantation in advanced stages.
Effect of drinking barley water on those with CKD
Barley is rich in potassium. Dr Ignatius states that while this mineral is essential for the normal functioning of cells, nerves and muscles, it can be life-threatening for people with CKD. Elevated potassium levels in the blood can be harmful when the kidneys are unable to filter it efficiently. This can lead to muscle weakness, irregular heart rhythms and in severe cases, heart failure.
Besides, overconsumption of fluids can also lead to issues in those with CKD. Dr Sankaran shares that one of his patients, a Sanskrit scholar, drinks a lot of water after chanting prayers. “Because of this, he requires more frequent dialysis sessions — sometimes, it needs to be performed every day,” he adds. Hence, those with CKD are advised to control their fluid consumption, which includes the amount of barley water consumed.
What precautions should one keep in mind?
People with CKD, especially those undergoing dialysis or in advanced stages, must manage their fluid and dietary intake. “Excessive consumption of fluids, including barley water, can lead to fluid overload, leading to the risk of conditions such as pulmonary edema, a dangerous accumulation of fluid in the lungs,” says Dr Sankaran. He adds, “People on dialysis do not pass much urine. So, when they consume more fluids, they require more frequent dialysis — and emergency dialysis in case of pulmonary edema.”
Experts explain that dietary management in CKD involves limiting certain nutrients, including potassium, to prevent complications. Dr Ignatius explains that the lack of scientific studies about the efficacy of barley in reducing creatinine levels or reversing CKD shows that it is important to follow conventional treatment methods and dietary advice given by the consulting nephrologist. While natural remedies and dietary interventions like barley water can be part of a healthy lifestyle, they cannot replace the need for traditional treatment methods, including medication, dialysis and lifestyle changes.
Takeaways
- While barley water offers various health benefits, its role in managing chronic kidney disease is limited to being part of a balanced diet rather than a curative remedy.
- There is no evidence that barley reduces creatinine levels.
- People with CKD should consume less potassium and intake of fluid must be limited. It is important to consult with the doctor before you add anything new to your diet.
