Salted zongzi is mainly composed of glutinous rice and mung beans (including red beans), fat pork, salted egg yolk, and other fillings added according to personal interests. There is also an alkaline zongzi made of alkaline water.

1. Salted zongzi is very hot and humid. Eating too much is easy to produce stomach gas and cause indigestion. Gastroenteritis is of course serious! So it is best not to eat more than 9 pieces for three days.

2. Relatively speaking, it is no problem to eat more zongzi in alkaline water, but it should be moderate, no more than four a day.
