Supper usually means eating again after dinner, and eating at 9: 00 pm to 4: 00 am is usually called supper. Under normal circumstances, at 9: 00 pm, all organs in the body are in a state of semi-rest. Occasionally eating a midnight snack at 9: 00 pm will not cause harm to the body, but attention should be paid to the right amount.
Of course, if you eat a lot of food taken late at night for a long time, it will easily lead to indigestion in the stomach and increase the burden on the stomach, which will have a bad influence in the long run.
