There is still an interval of about 4 hours between eating dinner and going to bed, so it is no problem to eat spinach for dinner, but it is not recommended to eat too much spinach before going to bed for the following reasons:
1, cellulose can't be digested in time: after people fall asleep, the metabolic ability of the body is weakened to save physical strength, and the digestive ability of the stomach will also be weakened. Spinach is rich in crude fiber. If you eat spinach before going to bed, spinach rich in cellulose may accumulate in your stomach overnight without being digested, and it is easy to have bloating and bad breath in the morning.
2, oxalic acid can not be metabolized in time: spinach is rich in oxalic acid, and the oxalic acid that is generally eaten will be excreted with urine after passing through the kidney. If you eat spinach at night, oxalic acid is not excreted in time, and oxalic acid is deposited in the body, which is easy to form stones with calcium and magnesium in the body, affecting kidney health.
