When summer comes, many people will be greedy for cold food and like to eat all kinds of frozen cold food. At that time, it tasted cool and comfortable. So, does eating cold food affect their health?

Does eating cold food have an effect on the body? 1 1, causing gastrointestinal dysfunction.

Eating a lot of cold drinks in hot summer will cause the blood vessels in the gastrointestinal tract to contract suddenly, reduce the blood flow, and make the normal physiological function of the gastrointestinal tract disorder. Because a large number of liquid components enter the stomach, the acidity in the stomach will be reduced, the bactericidal effect will be weakened, and it is easier to induce gastrointestinal inflammation.

2, induce throat inflammation.

Eating a lot of cold drinks will also cause the blood vessels in the pharynx to contract, the blood flow will decrease, the local resistance will decrease, and the bacteria in the upper respiratory tract will multiply in large numbers, causing throat inflammation.

3, reduce appetite

The main ingredients of cold drinks are nothing more than sugar and milk. These substances are high in calories and can supplement the human body's need for heat energy, but other nutrients are relatively few. Therefore, after eating a lot of cold drinks, the appetite will be reduced, the normal eating rules will be disrupted, and eating a lot of sweets will easily lead to nutritional imbalance.

4, 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. Therefore, among people who like to eat ice cream, ice cream has naturally become the chief culprit of obesity, and Amy MM must stay away!

5, affect the digestive system

Frozen food is easy to stimulate gastric mucosa, reduce gastric juice secretion, and even have stomach cramps. The decrease of gastric juice secretion will reduce the bactericidal ability, which will open the door for the growth and reproduction of bacteria in the intestine. At this time, if you eat food with bacteria or viruses, diarrhea, enteritis, dysentery and other intestinal infectious diseases will occur.

6, menstrual pain

In hot summer, a cold drink is the best choice, but female friends must pay attention. Scientific research has found that whenever cold drinks enter the human stomach, women's endometrial blood vessels will contract strongly, leading to a sharp decline in menstrual flow, and even symptoms such as amenorrhea and dysmenorrhea, so female friends must not be greedy during the physiological period!

So it's ok to eat some cold drinks in summer, but it must be moderate. I hope you can grasp it properly, seek advantages and avoid disadvantages, and achieve the goal of ensuring health.

What are the precautions for drinking cold drinks in summer?

Don't eat a lot of cold drinks after exercise

After strenuous exercise, the body temperature will rise. Eating a lot of cold drinks at this time is a strong cold stimulus to the digestive tract, which will cause strong peristalsis of the digestive tract and produce abdominal pain and diarrhea. Dramatic changes in heat and cold can also lead to sudden contraction of blood vessels in the stomach. Too many times, it will cause digestive and absorption dysfunction, leading to indigestion or other diseases.

It is not advisable to eat cold drinks before and after meals.

Eating cold drinks within 30 minutes before and after meals will dilute gastric juice and reduce the activity of digestive enzymes, which is not conducive to the digestion and absorption of food and harmful to human health.

4. Pregnant women and children should avoid eating too many cold drinks.

During pregnancy, a woman's placenta will produce a lot of progesterone, which will reduce the tension of gastrointestinal smooth muscle, gastric acid and gastrointestinal peristalsis. At this time, gastrointestinal mucosa is very sensitive to cold and hot stimuli. Pregnant women who eat more cold drinks will suddenly contract gastrointestinal blood vessels, reduce gastric juice secretion, reduce digestive function, and have symptoms such as loss of appetite, indigestion, diarrhea, abdominal pain and stomach cramps.

Children who eat too many cold drinks will cause abdominal pain, because eating too many cold drinks will make the gastrointestinal tract suddenly catch cold, stimulate the nerve endings in the intestinal mucosa and gastrointestinal wall, cause irregular contraction of the gastrointestinal tract, and cause abdominal pain. In addition, the stimulation of supercooling will accelerate the gastrointestinal peristalsis of children and reduce the blood flow, so that the intestinal contents can not be well absorbed and excreted, causing indigestion.

If the sugar content of ice is high, it may also provide breeding conditions for bacteria in teeth and increase the risk of oral inflammation;

2, stimulate the gastrointestinal tract: after the ice enters the gastrointestinal tract, due to the excessive temperature difference, it will stimulate the gastrointestinal tract to produce strong pain, and may also lead to increased gastrointestinal peristalsis, which may easily lead to stomach cramps, intestinal cramps and other diseases;

3, affecting appetite: ice will slow down the metabolism of the human body, slow down the digestion of the stomach, may affect the intake of normal meals, and easily lead to malnutrition;

4. Damage to blood vessels: Ice can stimulate the contraction of human blood vessels, which can lead to an increase in blood pressure. For patients with hypertension, myocardial infarction and coronary heart disease, this danger is even greater. It is easy to lead to insufficient blood supply and life-threatening;

5, causing obesity: such as ice cream, ice cream and other icy things themselves have high calories. Stimulated by low temperature, gastrointestinal digestion slows down, leading to energy consumption, which is easy to be converted into fat, leading to obesity;

6, causing dysmenorrhea: Some women eat ice during menstruation, which is easy to stimulate the whole body blood vessels, including endometrial blood vessels. When blood vessels contract violently, it is easy to cause dysmenorrhea or irregular menstruation.

Second, Chinese medicine:

1, moisture deposition: ice is easy to produce moisture and cold, easy to accumulate in the body and can not be discharged, which will lead to the decline of human physique, becoming weak and more prone to illness;

2, spleen and stomach damage: Chinese medicine believes that "the spleen likes dryness but does not like dampness" and "the stomach likes warmth but does not like cold". The stimulation of cold food will affect the spleen and stomach, and it is more prone to abdominal pain, diarrhea, bloating and other symptoms.
