Disadvantages of supper:

(1), easy to stone

The peak of calcium excretion is usually 4 ~ 5 hours after eating. If the supper is too late, when the peak of calcium excretion comes, people have gone to bed and fallen asleep, and urine will remain in the urinary tract such as ureter, bladder and urethra, which can not be excreted in time, resulting in the continuous increase of calcium in urine, which is easy to deposit and form small crystals. Over time, it will gradually expand to form stones.
