The disadvantages of drinking more juice, more and more people like to drink juice in life, because the taste of juice is better, and many people may become addicted. The main components of fruit juice drinks are sugar, carbonated water and pigment, which are harmful to health. The following is an understanding of the disadvantages of drinking more juice.

Disadvantages of drinking more fruit juice 1 The sugar content of a cup of fruit juice is much higher than that of a fruit, because a fruit only contains about 60 ml of fruit juice, and it takes three fruits to squeeze a cup of 200 ml of fruit juice, so the fructose in the fruit naturally flows into the fruit juice. Each cup of juice contains about 120 kilojoules, which is equivalent to the energy of a box of soft drinks. Fruit is a solid food, and one or two people will feel full after eating it, while fruit juice is a liquid, which cannot provide a feeling of fullness. Some people still think that drinking two or three cups of juice is not enough, so they unconsciously consume too much sugar, which may cause the following four hazards:

1, may suffer from "juice syndrome": low sodium reactions such as abdominal distension, dizziness, vomiting, etc. Because fruit is rich in "potassium" element, and potassium and sodium are mutually gram, if you drink too much juice, you will have a low sodium reaction.

2. Excessive intake of fructose cannot be absorbed and utilized by the human body, but is excreted from the kidney. Excessive drinking for a long time may lead to kidney disease, resulting in a disease called "juice urine".

3, weight change: drinking a lot of juice for a long time will either make people thin or make people fat. Fruit juice contains incomplete nutrients. If children drink it for a long time, it will affect their appetite and they can't eat according to normal rules. As a result, the more they drink, the thinner they get. For adults, too much fruit juice will only increase too much sugar and make people fatter and fatter.

4. Drinking more fruit juice is easy to get dental caries: In addition to mineral water, general drinks have different degrees of demineralization on enamel, which can lead to the dissolution of calcium and phosphorus in enamel. Among them, the total dissolution of calcium and phosphorus in fruit juice is the highest. This is because fruit juice drinks contain natural fructose and glucose, which will damage teeth to some extent and increase the risk of caries.

In addition, juice drinks (excluding freshly squeezed juice at home) generally contain various additives, such as colorants and preservatives. Drinking more is not good for your health.

The downside of drinking more juice: juice will make you anemic.

Fructose will hinder the body's absorption of copper. The lack of copper will affect the production of hemoglobin, which will lead to anemia. Einstein Medical Center conducted a retrospective survey of more than 0/00 anemia children in/kloc, and found that more than 80% of them had a hobby of drinking fruit juice.

Domestic survey data show that the physical development of children addicted to juice drinks is polarized, either too thin or too fat. Because the sugar content of fruit juice drinks is too high, children can get a lot of heat energy from it after drinking, which affects eating dinner. This will inevitably lead to insufficient intake of protein, some vitamins, minerals and trace elements, which will affect physical and intellectual development.

Two: it is easier to increase fat accumulation.

Fruit juice contains a lot of fructose. Experts point out that eating a lot of fructose will increase the risk of heart disease and type 2 diabetes, because fructose is more easily converted into fat by the liver than glucose.

Many research reports show that fruit juice is good for health and can lose weight. In 2008, a survey of 3,665,438+08 children aged 2 to 65,438+065,438+0 found that children who drink at least 6 ounces (about 65,438+077 ml) of fruit juice every day are lighter and have more vitamins and minerals than children who don't drink fruit juice at all. However, many experts believe that this data only reflects the correlation between fruit juice and healthy diet, not the causal relationship.

Three: artificial pigments affect IQ.

Whether it is a fruit-flavored drink or a low-concentration juice drink, artificial colors will be used-bright colors will allow consumers to associate drinks with fruits in their perception. When the fruit juice content is too small to make the beverage have rich and colorful fruit colors, cheap artificial colors are the best choice. The harm of artificial pigments to human body, especially children, has long been studied in modern nutrition.

In 2008, researchers from the University of Southampton surveyed 100 children and found that synthetic pigments would affect children's intellectual development. Children who often drink fruit juice and drink less water often have poor appetite, hyperactivity, bad temper and light weight.

Seven kinds of chemical additives such as lemon yellow and sunset yellow will reduce children's IQ by 5 points. Lemon yellow is a yellow food pigment contained in pea paste and cotton candy, and it is forbidden to be used in food and drink of children under 3 years old. On the other hand, quinoline yellow is an edible pigment often added to fruit juice drinks, soft drinks and cold capsules. Sodium benzoate, a preservative widely used in fruit juice drinks, is also harmful to health.

Four: calories are higher than soda.

According to American media reports, more and more doctors, scientists and public health officials believe that drinking more natural fruit juice may not be beneficial to health. Obesity caused by drinking natural fruit juice is no different from drinking soda such as cola and saccharin alcoholic drinks. A glass of juice is mixed with the sugar of multiple portions of fruit. If calculated according to the same weight, juice contains more calories than soda. You probably can't imagine that a cup of 240 ml pure fruit juice generally has about 100 calories, which is higher than the recognized "obesity drink" cola.

Five: Eight days will make you dependent on sweet drinks.

Some experts worry that children who drink a lot of sweet drinks will like sweets more when they grow up. A study in the Netherlands in 2004 found that children aged 8 to 10 preferred sweet drinks after drinking sugary orange juice for eight consecutive days. They also drink more because they are used to the sweetness of orange juice.

Disadvantages of drinking more fruit juice 3 The composition of fruit juice is similar to that of carbonated drinks.

100% fruit juice contains some vitamins and phytonutrients, which are not found in most sugary drinks, but the main components of these two drinks are sugar and water. Although the sugar contained in sugary drinks is added during processing, and the sugar contained in 100% fruit juice is naturally present, they will cause the same biochemical reaction in human metabolism. But compared with carbonated drinks, drinking fruit juice in moderation is better.

The efficacy of fruit juice

1, prevent body aging and help cell regeneration.

Fresh fruit and vegetable juice contains a lot of natural plant components, which has a positive impact on cell division and birth. Moreover, fresh fruit and vegetable juice will provide other necessary nutrients for human body, which not only promotes the growth of cells, but also prevents the body from aging.

2. Make fruits and vegetables into juice to better absorb nutrients.

Fruit and vegetable juice made of fresh fruits and vegetables contains a lot of vitamins and minerals. In the process of making fruit juice, the blender will cut the fiber dimension of fruits and vegetables more finely, and some very fine nutrients contained in cellulose will become a state that can be absorbed by the human body. And drinking like this is more conducive to digestion than eating fruits and vegetables raw.

3. Vitamins and minerals in fruit and vegetable juice have detoxification effect.

Drinking fruit and vegetable juice for a long time will not only improve our body's resistance, but also make our brain more energetic. Fruit and vegetable juice is a concentrated state in which various nutrients in fresh fruits and vegetables are easily absorbed by the human body.

4, clean the stomach

Human excrement sometimes interferes with intestinal digestion and absorption, and bacteria can easily invade the human body because various fluorobutyric acids produce toxic substances. If you drink fruit and vegetable juice, the inorganic bases, alkaloids and acids in fruit and vegetable juice will decompose and excrete intestinal excreta, so it is effective to solve constipation, promote the activity of large intestine and prevent common diseases.

5, to prevent human acidification

Fresh fruit and vegetable juice is rich in alkaline minerals, which can neutralize acidic substances in blood, transform acidic constitution into alkaline constitution and improve our immunity. If immunity is enhanced, our resistance to diseases such as allergies, hepatitis and colds will be strengthened.

Misunderstanding of fruit juice

Drinking fruit juice can replace eating fruit.

Fresh fruit juice is really the closest thing to fresh fruit, but drinking fruit juice can't replace eating fruit. After the fruit is squeezed into juice, the pulp and membrane are removed, and in this process, vitamin C will also decrease; Fruit juice drinks are generally sterilized at high temperature, and many nutrients are lost. In addition, the plant fiber in fruit is also healthy, but it will also be eliminated when juicing.

Fruit juice can replace boiled water.

Additives will be added to fruit juice drinks more or less. If you drink a lot, it will cause bad irritation to the stomach and increase the burden of kidney filtration.

Drink more juice, the better.

Because a lot of sugar in fruit juice can't be absorbed and utilized by the human body, it is discharged from the kidneys. Excessive drinking for a long time may lead to kidney disease, resulting in a disease called "juice urine". In addition, excessive intake of fructose can cause indigestion and acidosis.

Take medicine and juice together.

Fruit juice contains a lot of vitamin C, which is acidic. If some acid-resistant or alkaline drugs are taken together with fruit juice, it will not only reduce the curative effect, but also cause adverse reactions. If sulfonamides are taken with fruit juice, it will increase the burden on the kidneys and be harmful to the health of patients.
