First of all, frozen food is easy to stimulate the mucosa in the stomach, reduce the secretion of gastric juice, and even have stomach cramps, which affects people's appetite and digestion and absorption of food. Because the secretion of gastric juice is reduced, the sterilization ability is reduced, which opens the door for the growth and reproduction of bacteria in the intestine. At this time, if you eat cold drinks or other foods with bacteria or viruses, there will be intestinal infectious diseases such as diarrhea, enteritis, dysentery and typhoid fever.
Secondly, ice cream mostly contains pigments, flavors, preservatives, saccharin and so on. It is harmless to the human body.
Nutrients, some pigments and essences can easily cause allergies, asthma, laryngeal edema, urticaria, itchy skin and nervous headache. Too high concentration of saccharin can also cause cancer, so you can't eat ice cream every day.
