The hazards, taboos, and precautions of eating cold drinks in summer
Nowadays, cold drinks can be said to be another delicacy for people, loved both in cold winters and hot summers. And once people mention cold drinks, they will associate them with popsicles and ice cream, but do you know the origin of cold drinks? In fact, cold drinks appeared as early as the Shang Dynasty about three thousand years ago. At that time, wealthy families chiseled ice in winter and stored it in cellars, so that it could be used to cool off during the hot summer of the following year. During the Zhou Dynasty, there was a "Lingren" who was in charge of "ice power". In the late Spring and Autumn period, feudal lords enjoyed drinking chilled rice wine at banquets. There is a record in the "Chu Ci: Summoning the Soul" that says "when you drink it horizontally, it cools down a bit. In the Tang Dynasty, there was a public sale of ice products. In the Song Dynasty, the constantly developing cold drinks began to add new varieties, and it can be said that cold drink specialty stores emerged. There is a poem by Yang Wanli that goes like this: "On the sixth day of June, the imperial city stops at noon, and the people in the city are sweating like cooking. When selling ice, they come across the water, and the pedestrians are not satisfied." At that time, ice shops in Bianjing, Northern Song Dynasty, sold "rock sugar ice and snow ice and snow ice dumplings", and cold sour plum soup had already appeared. In the Southern Song Dynasty, there were "Snow soaked Plum Blossom Wine" and "Snow soaked Dou'er Water" sold on the streets of Lin'an. After the Yuan Dynasty, ice cream appeared. In the scorching summer sun, people are prone to dry mouth and tongue. If you can enjoy ice cream and cold beer at this time, not only to relieve the heat, but also to taste fresh and delicious food, why not? However, it should be noted that although cold drinks can play a certain role in cooling down and replenishing body fluids, they should also be consumed in moderation. Once consumed excessively, it can cause harm to the body and even endanger health. In summary, excessive consumption of cold drinks can have several harmful effects on the body, including:

The harm of eating cold drinks in summer
(1) Excessive consumption of cold drinks can easily cause gastrointestinal dysfunction. Eating a large amount of cold drinks in hot summer can cause sudden constriction of gastrointestinal blood vessels, reducing blood flow and leading to disruption of normal physiological functions of the gastrointestinal tract. In addition, due to the large amount of liquid components entering the stomach, the acidity in the stomach will be rapidly reduced, and the bactericidal effect will be relatively weakened, making it easier to induce gastrointestinal inflammation.
(2) Moreover, excessive consumption of cold drinks can also lead to decreased appetite. Generally, cold drinks only contain two main components: sugar and milk, which have high calories. Although they can supplement the body's need for heat energy, they lack other nutrients. Therefore, consuming a large amount of cold drinks can reduce appetite and disrupt normal eating habits.
(3) It can trigger inflammation in the throat. Eating a large amount of cold drinks can also cause constriction of blood vessels in the throat, reduce blood flow, lower local resistance, and lead to the proliferation of bacteria in the upper respiratory tract, triggering inflammation in the throat.
In the hot summer, many people like to eat cold drinks to cool down, especially when they come home from school or work with dry mouth and tongue. They can easily take out cold drinks from the fridge and have a big meal, which is really refreshing. However, this way of eating is actually very unscientific. So, how can eating cold drinks be beneficial to health?
Firstly, cold drinks should be consumed in moderation. When the human body consumes a large amount of cold drinks, it will cause constriction of the gastric mucosal blood vessels, reduce gastric juice secretion, not only reduce appetite, but also affect the digestion of food by the body. So the intake of cold drinks must be strictly controlled, with a recommended amount of around 150 milliliters per serving.
Secondly, cold drinks should be consumed in a timely manner. Don't think that you can eat cold drinks at any time. There are also certain time limits for consuming cold drinks. Eating cold drinks before meals can affect appetite and lead to nutritional deficiencies. Although cold drinks contain nutrients such as milk, their content is far less than that of a normal diet, and there are no vitamins or other components, so cold drinks should not be consumed as food.

Eating cold drinks can reduce stomach acid secretion, weaken the immune function of the digestive system, lead to bacterial growth, and cause intestinal diseases such as enteritis. Therefore, when eating cold drinks, it is important to avoid the two time periods before and after meals.

The harm of eating cold drinks in summer
Thirdly, do not eat cold drinks too quickly. In the scorching summer, drinking a bottle of chilled cola and eating a few popsicles in one breath can be considered a beautiful thing. But it poses great harm to the body. Even when drinking cold drinks, one should not drink too quickly. It should be like drinking hot soup, taking one sip at a time and savoring it carefully. Fourth, pay attention to the quality of cold drinks. When purchasing cold drinks, you should carefully check the production date and shelf life, try to choose products with a closer factory date, avoid buying cold drinks from roadside stalls, and pay attention to food hygiene.
In addition, different groups of people need to adjust their choices of cold drinks according to their own conditions. So, what should different groups of people pay attention to when consuming cold drinks? Specifically, the following groups of people should be particularly careful when consuming cold drinks.
(1) Elderly and young children. Due to their weaker physical constitution, consuming a large amount of cold drinks in a short period of time may lead to oral muscle paralysis, spasms, gastrointestinal dysfunction, accelerated intestinal peristalsis, and easily cause abdominal pain and diarrhea.
(2) Kidney disease patients. Such people should not eat cold drinks containing essence, pigments, spices and other ingredients. It should be known that these ingredients will increase the burden of glomerular filtration and detoxification, and aggravate edema symptoms.
(3) Patients with diabetes. Cold drinks generally contain high levels of sugar, which can lead to elevated blood sugar levels and worsen the condition for patients after consumption.
(4) Obese patients. Cold drinks contain more sugar, which can increase the conversion of liver glycogen into fat. Consuming too much cold drinks can make the body more obese.
(5) Pregnant women. Pregnant women consuming cold drinks not only affect their own gastrointestinal function, but also damage the fetal gastrointestinal function, leading to weakened digestive function and ultimately affecting the health of newborns.

reminder
In extremely hot summers, children always shout for ice cream. After all, the weather is hot, and if you can have a refreshing ice cream, it will make your child extremely happy. And now children are more spoiled and pampered, not only by their parents who spoil and love them, but also by their grandparents who coax and spoil them. As long as you want to eat a cold drink, you can eat it immediately without any hindrance. However, in reality, excessive consumption of cold drinks is detrimental to children's health, especially for those who are too young. Their gastrointestinal function is relatively weak, which can easily cause abdominal pain and diarrhea. Parents should not harm their children by indulging them excessively. They should learn to control their children's diet, give them a healthy childhood, and help them grow up healthy!
