The calcium content in dried shrimp is very high, making it an excellent source of calcium for the body. However, the timing of consuming dried shrimp is important; it is best to avoid eating it in the evening. The peak time for calcium excretion in the human body is generally 4 to 5 hours after a meal. If dinner contains too much calcium, or if dinner is eaten too late, when the peak of calcium excretion arrives, people are already in bed resting. As a result, urine will be retained in the urinary tract and cannot be expelled from the body in a timely manner.
This causes the calcium concentration in the urine to continuously increase and deposit. Over time, this can easily lead to the formation of urinary tract stones.
