"You know what? You should eat less of these three foods, especially at our age. These are the words that Dr. Cheng said to a patient during one of the hospital's daily ward rounds.
Dr. Cheng, a veteran nephrology doctor, caught the attention of the patients present, especially after he recently encountered a distressing case.
Wang Li, a 40-year-old librarian, died of severe kidney failure. But incredibly, it was her seemingly healthy eating habits that quietly damaged her kidneys.
Wang's diet includes plenty of potassium-high foods, such as bananas, oranges, and spinach, which are generally good for health. However, for people with kidney insufficiency, too much potassium can cause abnormal potassium levels in the blood, leading to heart problems and even cardiac arrest.
Wang's diet also includes a lot of red meat and dairy products, which are high-phosphorus foods that are generally not harmful to healthy people, but excess phosphorus can lead to increased blood phosphorus levels in people with kidney disease, which can increase the risk of cardiovascular disease. In addition, she eats seafood and soy products, which are high-protein foods that further aggravate her already heavy kidneys.
Wang Li's case is a classic warning that even seemingly healthy foods can have serious consequences if not consumed in moderation according to an individual's health status. In the process of handling Wang Li's case, Dr. Zheng deeply felt the importance of popularizing information on the prevention and treatment of kidney disease.
Shortly after Wang Li's death, Dr. Cheng began sharing the case in hospital and public health talks, emphasizing the need to avoid or reduce the intake of three high-risk foods in the daily diet, especially for those who already have kidney dysfunction or are at risk of kidney disease.
He explained in detail how each food affects the health of the kidneys and suggested alternative foods. For example, low-potassium fruits such as apples and pears, low-phosphorus protein sources such as chicken and eggs are recommended, and other low-protein foods are recommended to replace seafood and soy products.
Through Dr. Cheng's efforts, more and more people are beginning to realize that even "healthy" foods need to be consumed appropriately according to the individual's health status. His lectures and educational activities have gradually gained popularity with patients and the general public, and have had a positive impact on raising awareness of kidney health.
At the end of a lecture, an audience member asked, "Dr. Cheng, I have recently seen a slight decline in kidney function, how should I adjust my diet to prevent further kidney damage?" ”
Dr. Cheng smiled and answered the question seriously: "This is a very practical question. When it comes to dietary modifications, you should minimize your salt intake, as too much salt can increase the burden on your kidneys, leading to an increase in blood pressure, which can accelerate the decline in kidney function. ”
At the same time, it is necessary to limit the intake of protein, especially animal protein, because excessive protein metabolism produces a large amount of waste and increases the clearance pressure on the kidneys.
He continued: "When it comes to potassium and phosphorus intake, while you don't have to be too strict at this stage, it is recommended that you pay attention to your food choices and avoid foods high in potassium and phosphorus, such as some nuts, legumes, dairy products and processed meats. ”
Also, eat foods rich in antioxidants, such as berries, apples, and carrots, which can help lower inflammation and protect kidney health.
Dr. Cheng also emphasises the importance of regular check-ups: "In addition to dietary modifications, I also recommend that you have regular kidney function tests to monitor the health of your kidneys. In this way, potential problems can be detected in time and appropriate measures can be taken to prevent the further development of kidney disease. ”
Through this Q&A, Dr. Cheng not only provided specific dietary advice, but also helped the audience better understand how to protect kidney health through small changes in daily life, so that everyone can make the most suitable dietary choices according to their health status.
"If you're used to eating high-potassium bananas as a snack, try replacing them with apples or pears," he says. These fruits are relatively low in potassium and are also rich in fiber and other nutrients that can be beneficial for health. ”
Dr Cheng also emphasises the importance of vitamin C and recommends foods rich in it: "Vitamin C is a powerful antioxidant that can help reduce free radicals in the body and protect cells from damage. People with kidney disease or at risk of kidney disease can increase their vitamin C intake by eating citrus fruits, strawberries or tomatoes. ”
He advises people with unhealthy kidneys to consult with a medical professional before making any dietary changes to ensure that their choices are conducive to the improvement or maintenance of their health.
Dr Cheng has been effective in raising public awareness of the importance of kidney health and daily dietary choices, and more people have learned that even everyday foods need to be consumed in moderation according to an individual's health status. His expertise and in-depth answers helped the audience understand how to promote and protect their kidney health through simple daily choices.
