1, affecting appetite
The main ingredient of cold drinks is water, in addition to some sugar and milk. These things are low in nutrients and cannot provide nutrition for the body. If too many cold drinks enter the digestive tract, it will seriously affect the secretion of digestive juice and the digestive function of the gastrointestinal tract.
Digestive juice contains gastric acid and digestive enzymes, which helps to kill bacteria entering the digestive tract and promote the digestion and absorption of food entering the gastrointestinal tract. The decrease of digestive juice will affect the digestion and absorption of food, which will easily lead to intestinal infection, loss of appetite and affect normal diet.
2, cause gastrointestinal dysfunction
Ice cream belongs to high-fat and high-sugar food, and the temperature is generally around 0℃. However, the normal body temperature is 37℃. Such a wide temperature difference will cause great stimulation to the gastrointestinal tract, lead to vasoconstriction of the gastrointestinal tract, weaken the protective barrier of gastric mucosa, cause intestinal dysfunction and even cause acute gastroenteritis.
3, causing obesity
The ingredients of ice cream contain a lot of fat, sugar and protein, which is high in calories. 100g ice cream will bring 220 kilocalories, which is equivalent to the heat of more than 2 rice.
4, menstrual pain
In the hot summer, drinking a cold drink is the best choice, but female friends must pay attention to that whenever a cold drink enters the human stomach, women's endometrial blood vessels will contract strongly, which will lead to a sharp decline in menstrual flow and even symptoms such as amenorrhea and dysmenorrhea, so female friends must not be greedy for cold during the physiological period.

Precautions for eating ice cream
First, it is healthier to chew slowly.
Swallowing all the ice seems infinitely refreshing, but it is actually very harmful. It will not only harm the gastrointestinal tract, but also cause some blood vessels to contract rapidly, resulting in poor blood flow. Spasms caused by excessive cold can also cause abdominal pain in some people.
Eating snacks on ice can buffer the coolness in the mouth and protect the digestive tract and internal organs from excessive cold to the greatest extent.
Second, three meals are approaching, so don't touch the cold.
An ice cream before meals will reduce the intake of staple food, or lead to a complete loss of appetite. After catching cold, the sterilization function of the stomach and intestines is weakened, and if you eat, you are more vulnerable to the bacteria in food.
After a meal, an ice cream will make the stomach contract, reduce the secretion of gastric acid, cause indigestion, and even severe gastrointestinal damage such as intestinal spasm.
Third, don't refreeze the melted ice cream.
If the melted ice cream is frozen again, the quality of the ice cream will be seriously reduced, and bacteria will easily breed, so the melted ice cream should not be put back in the refrigerator, and such low-priced ice cream should not be bought cheaply.
Choose ice cream, try to choose ice cream stored in a closed freezer at MINUS 18 degrees. If the package is complete, don't buy deformed ice cream, because it is likely to melt and deform during transportation or sales, and then freeze.
