In fact, patients with kidney disease can eat less of all the above foods. Doctors do not allow patients to eat these foods, mainly because they are afraid that patients will not be able to control the "quantity", which will put a burden on the kidneys and cause kidney disease to relapse. However, there are four foods that patients with kidney disease must not eat and are taboo.

Carambola

In areas where carambola is produced in large quantities, normal people will experience hematuria after eating carambola. Because certain substances in carambola can damage the glomerular capillary basement membrane and epithelial cells, leading to hematuria.

Not only that, carambola contains a neurotoxin, and patients with kidney disease will be poisoned or even die if they eat carambola. As long as a kidney patient eats one carambola or drinks 100ml of carambola juice, the toxins in the carambola will cause harm to the kidney patient in a short period of time.

Carambolas should not be eaten by patients with kidney disease.

Houttuynia cordata

It is often eaten as a salad in Sichuan and Yunnan. But in Chinese medicine, it has diuretic and swelling effects. Although it has diuretic and swelling effects, the aristolocholactam contained in Houttuynia cordata can cause irreversible damage to the kidneys and lead to upper urothelial cancer.

Therefore, it is not recommended for patients with kidney disease to consume it as food. They must follow the doctor's advice to take it as a herbal medicine.

Crayfish

There are many reports about crayfish on the Internet. Many people eat crayfish, causing kidney damage and even kidney failure. Among them, eating crayfish causes rhabdomyolysis syndrome. It refers to the acute destruction and dissolution of skeletal muscles, releasing large amounts of myoglobin, creatine phosphate kinase and other muscle cell contents into the peripheral blood.

The biggest hazard is that the myoglobin released into the blood can easily block the renal tubules, leading to acute renal failure. The main symptoms are sudden muscle pain, muscle weakness, and soy sauce-colored urine.

So, patients with kidney disease cannot eat it.

High-salt processed foods

Normal people consume 6g of salt per day, while patients with kidney disease consume 2-3g or even less. For patients with kidney disease, high salt can aggravate high blood pressure, increase urinary protein excretion, aggravate edema, develop drug resistance, and prevent the drug from fully exerting its efficacy.

In our daily lives, many processed foods contain high amounts of salt, including ham, smoked fish and bacon, pickles, preserved fruits, canned cooked foods, etc., all of which contain large amounts of salt. Although you can’t taste some salt, you can actually eat a day’s worth of salt, such as preserved fruits.
