1, nutritional difference: it is best not to juice fruit. Drinking freshly squeezed fruit juice at home can get almost the same nutrients as eating fresh fruit, such as sugar, fat and trace elements, but the biggest disadvantage is that the fruit loses a lot of dietary fiber necessary for human body in the process of fresh squeezing.

2, efficacy difference: water-soluble fiber represented by pectin has the health care effect of preventing and reducing diabetes and cardiovascular diseases; The water-insoluble fiber can better prevent the pathological changes of gastrointestinal system.

Water-insoluble fiber can stimulate intestinal peristalsis and promote defecation. Food fiber can affect the activity of bacteria in large intestine, reduce the production of cholic acid in large intestine, dilute toxic substances in intestine and reduce the contact time between carcinogens and intestinal mucosa, thus preventing intestinal carcinogenesis.

In addition, dietary fiber can also affect the blood sugar level, reduce the dependence of diabetic patients on drugs, prevent excess calories, control obesity, prevent gallstones and reduce blood lipids.

Juicing fruit is not good for children's health, and it is easy to make children's teeth lack exercise, facial skin and muscle strength weaken, and the adjustment function of eyeballs weaken. In addition, if you are unable to chew for a long time, your jaw will become underdeveloped, your teeth will be irregularly arranged, and your upper and lower teeth will be dislocated.

Children should eat some fruits rich in fiber and with certain hardness after their deciduous teeth are completely extracted, so as to enhance their chewing power and promote the development of gums, jaws and facial bones.

Extended data:

Drinking fruit juice can replace the misunderstanding of eating fruit

Fresh fruit juice is really the closest thing to fresh fruit, but drinking fruit juice can't replace eating fruit.

When the fruit is squeezed into juice, the pulp and membrane are removed, and in this process, vitamin C will also be reduced; Fruit juice drinks are usually sterilized at high temperature, and many nutrients are lost. In addition, plant fibers in fruits are also healthy, but they are also eliminated when juicing.

The misunderstanding that fruit juice can replace boiled water

Additives will be added to fruit juice drinks more or less. If they are drunk in large quantities, it will cause bad stimulation to the stomach and increase the burden of kidney filtration.

The more juice you drink, the better.

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

Misunderstanding of taking drugs and fruit juice together

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

Common sense knowledge

1. Fruit juice contains much less nutrition than fruit.

When the fruit is pressed into juice, the pulp and membrane are removed. In this process, vitamin C is also greatly reduced, and vitamin C is something you must take in large quantities.

If the fruit itself contains few vitamins, such as apples, then in this process, the vitamins are almost eliminated.

2. Fruits with more nutrition usually make fruit juice with more nutrition.

Such as citrus fruits. However, sometimes, some nutrients, such as vitamin C, are artificially added to fruit juice. Please read the label carefully to find out what substances are in it. Maybe some brands of apple juice or grape juice contain the vitamin C you need, but maybe other brands don't.
