Nutrition experts recommend that kidney patients need to be careful when using this dish to avoid putting more pressure on kidney function.
One of the important reasons is that bone soup often contains a fairly high amount of purine. During bone stewing, purines from bones, bone marrow and connective tissues can dissolve in broth. When entering the body, purines are converted into uric acid. If kidney function is impaired, the ability to excrete uric acid also decreases, increasing the risk of uric acid accumulation in the blood, causing complications such as gout or kidney stones.
In addition, many types of bone broth also contain a significant amount of phosphorus. For people with chronic kidney disease, the ability to remove excess phosphorus is reduced. When phosphorus accumulates in the blood, the body may experience mineral metabolism disorders, affecting bone health and increasing the risk of vascular calcification. This is one of the common complications in people with prolonged kidney disease.
Another factor is the fat content in bone broth, especially when using tubular bones or bones with multiple bone marrows. Excess fat can increase calories in the diet, contributing to overweight or dyslipidemia. These problems can increase the risk of cardiovascular disease – a complication that kidney patients are more likely to encounter than healthy people.
Many people have a habit of adding quite a lot of salt, seasoning powder or fish sauce to bone soup to enhance the flavor. But high sodium levels can cause the body to retain water, increase blood pressure and put greater pressure on the kidneys. Controlling salt intake is one of the important principles in the diet of people with kidney disease.
It is noteworthy that bone broth is not always as rich in calcium as many people think. Most of the calcium in bones does not easily dissolve into water during normal cooking. Therefore, drinking a lot of bone soup is not an effective solution to supplement calcium for the body.
People with kidney disease should limit eating bone soup because this dish may contain a lot of purines, phosphorus, fat and sodium - factors that can potentially increase the burden on the kidneys.
Instead, kidney patients should consult a doctor or nutritionist to build a diet suitable for their health condition, helping to better control the disease and improve the quality of life.
