As early as the Roman Empire, an emperor was so hot that he ordered his servants to look around for ice and snow to relieve the heat. A clever cook retrieved the unfrozen ice and snow from the mountain and stirred it with honey and fruit to quench the emperor's thirst with heat. This is probably the earliest in the world.
Untie the coat of ice cream
In fact, ice cream is a frozen drink: its main raw materials are food additives such as water, milk, eggs, sweeteners, oils and fats (including stabilizers, emulsifiers, colorants and various flavors and fragrances). Among them, "milk" can be fresh milk, milk powder, condensed milk, thin cream and whey powder; "Eggs" can be fresh eggs, frozen yolk, yolk powder and whole egg powder.
The most important ingredient of ice cream is cream. The American rule for ice cream is that it contains at least more cream fat. Good ice cream may be higher, and they will eventually become a semi-solid medium in ice cream, producing a delicate texture. There is usually a small amount of emulsifier to improve the fat particles and the final texture. Generally speaking, the more cream, the more upscale and delicious ice cream.
High in sugar and fat, not delicious.
The sugar content of ice cream is not low either. The sugar content of a can of Sprite/Coke is about 12%, while ice cream is usually 12%- 18%. In other words, its sugar content may be higher than sweet drinks.
Oh, don't forget that the fat content of ice cream ranges from 8% to 16%. Usually, the milk fat content of ice cream is 12%- 16%, and the fat content of high-quality ice cream will be higher. For example, the total fat content of Haagen-Dazs ice cream is generally around 17%, and the highest can reach 2 1.70%. The fat contained in ice cream mainly comes from cream and eggs, which may bring some cholesterol and some saturated fat.
These ingredients mean that although ice cream is cold, it is high in calories. If you eat a lot of ice cream for a long time, your weight loss plan may not be so smooth. In addition, with the widespread use of hydrogenated vegetable oil, ice cream may also become the source of trans fatty acids. Because in order to make ice cream delicious and reduce the cost, some products will use "margarine" or "partially hydrogenated vegetable oil" instead of real cream. This introduces "trans fatty acids" into ice cream. Trans fatty acids are bad for the heart. In recent years, it has been found that trans fatty acids have a strong role in promoting obesity.
Ice cream VS drugs?
Delicious ice cream always makes you want to stop. Do you want it after eating? The latest research found that you may be experiencing a feeling similar to drug dependence.
A few days ago, Dr Kyle Burger, a researcher at the Oregon Institute in the United States, fixed his research interest on the impact of ice cream on people. They provided Haagen-Dazs milkshake ice cream to 14- 16-year-old 15 1 teenagers, and scanned their brains with functional magnetic resonance imaging (fMRI). It was found that after eating ice cream regularly, the reactivity of reward-related parts such as striatum in their brains decreased, which was similar to the symptoms of long-term drug abuse. Is ice cream a drug?
Eating a lot of ice cream will reduce the reactivity of the reward area of the brain and raise the threshold of "feeling enough" This may be because dopamine receptors in the brain are reduced, which makes them need to eat more ice cream to achieve the same satisfaction.
This study may tell us that high-fat and high-sugar foods may not only provide high energy, but also reduce the response of brain reward areas to high-energy foods, making people have to eat more high-energy foods to enjoy the same * * *, which will also make people fat. This pattern of frequent downward adjustment is similar to that of long-term drug addicts. The more frequently a person takes drugs, the more drugs he needs to achieve the same goal.
Eating too much ice cream can cause headaches.
It's cool to gulp down ice cream in hot weather! However, when I drank it all at once, I suddenly felt that my head began to hurt. Is it wrong to open your mouth? In fact, it is not only ice cream, but also other cold foods. This is a series of chain reactions after extremely cold food or drink comes into contact with the root of the tongue. This symptom is called "ice cream headache" by medical scientists.
This kind of headache is generally located in the middle of the forehead, which usually appears after eating cold drinks quickly for a few seconds, and the pain reaches its peak in 30-60 seconds, and a few cases last for a long time; Occasionally, there is a case report of epilepsy induced by eating cold drinks.
Are migraine sufferers more likely to have an ice cream headache? The medical field is still controversial, but ice cream headaches are more likely to occur in hot summer than in winter. Some theories believe that a large amount of cold food leads to the rapid contraction and relaxation of sinuses capillaries, which leads to the production of pain receptors. There is also a theory that low-temperature food causes the contraction of maxillary blood vessels, and baroreceptors on the blood vessel wall inform the brain of this change. The human body suffers pain in order to ensure the blood supply to the brain and increase the blood volume of the anterior cerebral artery entering the brain.
No matter what the principle of headache is, even to relieve summer heat, you should try to slow down when eating ice cream, and be careful that eating too much ice cream may cause headaches. For people with a bad stomach, eating a lot of cold drinks will also increase the stomach.
Tip: Ice cream is very cold, so we can eat it in moderation when it is hot. But be sure to pay attention to the amount and don't eat too fast. In particular, women must pay attention to eating less cold things. So is ice water.
