Why can't you drink carbonated drinks? If I drink too much, it's easy to get nosebleeds in hot weather.

The main components of carbonated drinks include acidic substances such as carbonated water and citric acid, sugar, spices, and some also contain caffeine and artificial colors. Except that sugar can replenish energy for human body, aerated "carbonated drinks" contain almost no nutrients.

Carbonated drinks such as cola are deeply loved by everyone, especially the "younger generation" and children. However, health experts remind that drinking carbonated drinks should pay attention to a "degree".

Carbonated drinks contain high phosphorus content, and excessive drinking may change the proportion of calcium and phosphorus in human body. The researchers also found that compared with people who drink too many carbonated drinks, the risk of fracture of people who drink too many carbonated drinks will increase by about 3 times; At the same time of strenuous physical activity, excessive consumption of carbonated drinks may also increase the risk of fracture by five times.

Experts remind that childhood and adolescence are important periods for bone development. During this period, the children have many activities. If the intake of high phosphorus and low calcium in food is unbalanced, and carbonated drinks are drunk too much, we should pay enough attention to it. Because it may not only have a negative impact on the peak bone mass, but also lay the groundwork for future osteoporosis.

Therefore, everything must have a "degree". Once this "degree" is exceeded, nutritious food may become harmful or redundant, which is not good for human body; Secondly, supplementing a certain amount of calcium in time can also reduce the imbalance of calcium and phosphorus ratio in the body.

Edit what carbonated drinks are there in this paragraph?

(1) Carbonated drinks (soda) products subject to food production license management refer to drinks filled with carbon dioxide gas under certain conditions, including carbonated drinks, aerated sports drinks and other specific varieties, excluding drinks that produce carbon dioxide gas by self-fermentation. The content of carbon dioxide in the finished product (volume multiple at 20℃) is not less than 2.0 times. Carbonated drinks are mainly composed of sugar, pigments, sweeteners, souring agents, spices and carbonated water, and generally do not contain vitamins and minerals.

(2) Carbonated drinks (soft drinks) can be divided into juice type, fruity type, cola type, low-calorie type and other types, such as cola, sprite, Fanta, 7-up, mirinda and so on.

Edit the negative effects of this paragraph of carbonated drinks.

Carbonated drinks have a certain impact on people's health, mainly as follows:

1. Effects on bones

Osteoporosis caused by phosphoric acid

Most of the ingredients of carbonated drinks contain phosphoric acid, but this kind of phosphoric acid will affect bones subtly, and drinking carbonated drinks often will threaten the health of bones. Because the human body has requirements for various elements, a large intake of phosphoric acid will affect the absorption of calcium, resulting in an imbalance between calcium and phosphorus.

Once calcium is lacking, it will do great harm to the physical development of children during their growth. Lack of calcium undoubtedly means slow bone development and osteoporosis. According to some data, the risk of fracture of teenagers who often drink a lot of carbonated drinks is three times that of other teenagers.

Osteoporosis is a worldwide health problem, which attracts more and more attention. With the increase of age, the absorption rate of calcium gradually decreases, so middle-aged and elderly people are prone to osteoporosis, especially elderly women. Studies have shown that long-term consumption of carbonated drinks, especially milk and dairy products, is insufficient, which is very easy to cause osteoporosis. This is mainly because most carbonated drinks contain phosphoric acid. The intake of a large amount of phosphoric acid will affect the absorption of calcium, resulting in calcium and phosphorus imbalance, which in turn will affect bones and teeth. Because pregnant women are prone to calcium deficiency during pregnancy, they should also drink carbonated drinks as little as possible.

2. Influence on human immunity

For the convenience of storage and attractive taste, today's drinks are inseparable from food additives. In order to reduce the cost as much as possible, many beverage manufacturers always have a soft spot for additives, even exceeding the standard. Although many labels do not indicate the name of the additive, the test results show that its existence is an indisputable fact.

Nutritionists believe that healthy human blood should be alkaline. At present, carbonic acid, lactic acid, citric acid and other acidic substances have been added to drinks. In recent years, the proportion of animal foods such as meat, fish and poultry is getting higher and higher, and many people's blood is acidic. If more acidic substances are ingested, the blood will be in an acidic state for a long time, which is not conducive to blood circulation. People are prone to fatigue, decreased immunity, and various pathogenic microorganisms take advantage of it, making people susceptible to infection.

3. Effect on digestive function

Studies have shown that sufficient carbon dioxide can play a role in sterilization and bacteriostasis in beverages, and can also take away the heat in the body through evaporation to cool down.

But drinking too much carbonated drinks is not good for the stomach, and it will also affect digestion. Because a large amount of carbon dioxide can inhibit bacteria in drinks and beneficial bacteria in the human body, the digestive system will be destroyed.

Especially for young people, if they drink too much at once, the released carbon dioxide will easily cause abdominal distension, affect appetite and even cause gastrointestinal dysfunction. A lot of sugar is harmful to the health of organs.

Too much sugar in the beverage is absorbed by the human body, which will produce a lot of calories, which will easily lead to obesity if it is drunk for a long time. The most important thing is that it will bring a great burden to the kidneys, which is also one of the hidden dangers of diabetes.

4. Effects on nervous system

Interfering with the impulse conduction of the nervous system is easy to cause ADHD in children.

The survey results show that 46% people don't like carbonated drinks, and 29% people realize that drinking carbonated drinks for a long time is harmful to human health. Therefore, we should actively publicize in this regard. Make people realize the adverse effects of drinking too much carbonated drinks on health. Let people drink carbonated drinks as little as possible in their daily lives. Generally, it is best to choose boiled water with specific activity, or drink some fruit juice containing vitamins in moderation. People with hypertension, diabetes and hyperglycemia should try not to drink carbonated drinks. In addition, among teenagers, we can appeal to everyone to save the change for drinking carbonated drinks and do something beneficial to social construction, such as donating money to Project Hope and planting trees in an environmentally friendly way.

In addition, there are many people who should not use carbonated drinks!

Patients with hypertension, heart disease and diabetes should not drink alcohol; Children, pregnant women and lactating women are best prohibited.

Edit this paragraph to destroy the "energy factory" of human cells

A recent study in Britain shows that some carbonated drinks may cause serious damage to human cells. Experts believe that a common preservative in carbonated drinks will destroy some important areas of human DNA and seriously threaten human health.

It is reported that this kind of harm caused by drinking carbonated drinks is generally related to aging and alcoholism, which will eventually lead to diseases such as cirrhosis and Parkinson's disease.

The focus of this study is the safety of sodium benzoate. In the past few decades, this preservative code named E2 1 1 has been widely used in the global carbonated beverage industry, with a total value of 74 billion pounds. Sodium benzoate is a derivative of benzoic acid, which naturally exists in various berries. At present, it is widely used as a preservative for many well-known carbonated drinks.

Peter Piper, a professor of molecular biology and biotechnology at the University of Sheffield in the United Kingdom, is an expert on human aging. His experimental results prove that benzoic acid can destroy an important region in human mitochondrial DNA.

Mitochondria belong to a kind of organelle in human cells and are called "energy factories" in human cells. Its function is to use organic matter in cells as fuel, so that these organic matter can be combined with oxygen and converted into carbon dioxide and water, and at the same time, the chemical energy in organic matter can be released for cells to use. It breaks down ATP and provides 95% energy for human body. When our muscles contract and we are thinking, mitochondria are always working, providing energy for our neurons and muscle fiber cells.

Piper said: "These compounds will seriously damage mitochondrial DNA, thus completely stopping mitochondrial activity. In other words, they let mitochondria go on strike. " According to Piper, mitochondria can oxidize organic matter and release energy. If mitochondria are destroyed, cells will suffer from serious failure. Many diseases are related to this destruction, such as Parkinson's disease and other neurodegenerative diseases.
