In fact, patients with kidney disease can eat less of these foods. Doctors do not allow patients to eat these foods mainly because they are afraid that the patient cannot control the "amount" and bring burden to the kidneys, leading to the recurrence of kidney disease. However, there are four foods that kidney disease patients must not eat and are contraindications.
Carambola
In areas where carambola is widely produced, normal people may experience hematuria when eating carambola. Because a substance in carambola can damage the basement membrane and epithelial cells of glomerular capillaries, leading to hematuria.
Moreover, carambola contains a neurotoxin, which can cause poisoning and even death in kidney disease patients who consume it. Nephropathy patients only need to eat a carambola or drink 100 ml Star fruit juice, and the toxins in carambola will cause harm to patients with kidney disease in a short time.
Carambola cannot be consumed by kidney disease patients.
Houttuynia cordata
It is often eaten as a cold dish in Sichuan and Yunnan. But in traditional Chinese medicine, it has diuretic and anti-inflammatory effects. Although it has diuretic and detumescence effects, aristolochia lactam contained in Houttuynia cordata Thunb will cause irreversible damage to the kidney and lead to upper urothelium epithelial cancer.
Therefore, as a food, it is not recommended for kidney disease patients to consume it. As a herbal medicine, it must be taken according to medical advice.
Crayfish
There are many reports online about crayfish, and many people who eat crayfish can cause kidney damage or even kidney failure. The main cause of rhabdomyolysis syndrome is eating crayfish. It refers to a clinical syndrome in which skeletal muscles undergo acute destruction and dissolution, releasing a large amount of muscle cell contents such as myoglobin and phosphocreatine kinase into peripheral blood.
Its biggest harm is that the myoglobin released into the blood is easily blocked by renal tubules, leading to acute kidney failure. The main manifestations are sudden muscle pain, muscle weakness, and oily urine.
So, kidney disease patients cannot eat it.
High salt processed food
Normal people have a daily salt intake of 6g, while kidney disease patients have a daily salt intake of 2-3g or even less. For patients with kidney disease, high salt can increase blood pressure, increase urinary protein excretion, worsen edema, and cause drug resistance, making the efficacy less effective.
In our daily lives, many processed foods are high in salt, including ham, cured fish and meat, pickled vegetables, preserved fruits, canned cooked food, etc., which all contain a large amount of salt. Although you may not be able to taste the taste of salt, eating just one amount of salt is equivalent to a day's worth of salt.
