Kidney disease "alert": Do not touch these overnight foods!

1. Overnight green leafy vegetables

1. Risk of spoilage : Green leafy vegetables are rich in nitrates. After being left overnight, nitrates will be converted into nitrites under the action of bacteria. Nitrites not only have the risk of cancer, but also affect the normal metabolic function of the kidneys. For example, the nitrite content of spinach and celery will increase significantly after being left overnight.

2. Impact on kidney disease : The renal metabolic capacity of patients with kidney disease is already weak. Excessive intake of nitrite will increase the detoxification burden of the kidneys and further damage kidney function.

2. Overnight seafood

1. Breeding bacteria : Seafood is rich in protein and is prone to breed a large number of bacteria after being left overnight. Especially in summer, the bacteria in seafood left overnight at room temperature multiply very quickly.

2. Increase the burden on the kidneys : Spoiled seafood will produce harmful substances, and the kidneys need to work twice as hard to remove these substances. This is undoubtedly a double whammy for kidney patients and may cause the condition to worsen.

3. Overnight Soup

1. Changes in nutritional components : After soup foods are left for a long time, the nutritional components in them will change, not only reducing their nutritional value, but also producing substances that are harmful to health.

2. Risk of high salt and high purine : If the soup has a high salt content, or contains a lot of meat, seafood and other cooked ingredients, the salt will be concentrated overnight and the purine content may also increase, which is extremely unfavorable for kidney patients to control blood pressure and uric acid levels.
