Why eat less ice in summer? Summer is the hottest period of the year, so many people will be greedy for cold and eat some cold drinks, but when eating in summer, people's physical resistance is often very poor. Here's a detailed introduction to why they eat less ice in summer.

Why eat less ice in summer? The hazards of too many cold drinks are as follows:

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!

Why eat less ice in summer? Can I eat ice in the long summer?

The long summer hasn't arrived yet, but the hot weather can't wait any longer. The hot temperature has made everyone feel its existence. Summer is cool, and it is also the season to eat ice. Eating cold food is the most commonly used method to relieve summer heat, especially ice cream, cold drink and iced watermelon. However, if you eat too much cold food in summer, it will cause serious damage to the yang of the human body.

Why can't you eat ice in long summer?

Many people surrounded by heat like to eat some raw and cold food in this season. However, doctors believe that this eating habit will affect the health of the spleen and stomach, leading to deficiency and cold of the spleen and stomach, which will not only cause diarrhea and abdominal pain, but also affect the absorption of food.

For children, many children have poor immunity, weak constitution, dry food, no fat and even no appetite, which has a lot to do with eating cold food frequently. This phenomenon is very common in children's diet, and the smaller it is, the greater the impact on children's spleen and stomach.

As for the reason, the doctor said: the laws of nature pay attention to balance. The hotter the weather, the colder the internal organs. Otherwise, if both exterior and interior are hot, it will destroy the balance of yin and yang and cause human discomfort. In this case, if you eat raw and cold food again, it means that it is cold above, and the spleen and stomach are the basis of human transport. If you eat too much cold and cold food, the coolness will be transported to the whole body through the spleen and stomach, which will hurt the human yang, lead to hot summer, headache, chills, skin fever, aversion to cold, loss of appetite and other symptoms.

So if you can't be greedy, you can't touch it at all? The doctor said that the key to not being greedy is "not greedy". It's no problem to eat an ice cream and a cold dish once in a while. Drinking water is not necessarily hot water, but cold water at room temperature. On the contrary, if everything is hot, it will break the balance of the human body as mentioned above, and if you always eat hot food and sweat repeatedly, it will easily cause the human body to collapse and be harmful to health. Therefore, we should master the degree of everything and follow the laws of nature. "Letting nature take its course is often the best way to keep healthy."
