1. Fruit also contains a lot of cellulose and pectin, which can help clean the intestines. There is nothing in the juice.

2. The vitamins contained in the pulp may not all be squeezed into juice.

3. Sugar concentration after squeezing into juice is not good for your health. Drinking fruit juice will quickly increase blood sugar concentration and stimulate insulin secretion in a short time. Therefore, people with diabetes should not drink juice. Normal people should also try to keep blood sugar balance.

Fruit juice is much less nutritious than fruit. Fruit juice has no nutrition at all.

People drink fruit juice mostly because they think it is nutritious and delicious. Many people think that fruit juice can replace fruit, and drinking fruit juice can supplement nutrients (such as vitamin C) in fruit, especially for children who don't like fruit, and even completely replace drinking water.

Fruit juice can't replace fruit.

Old people and children drink less fruit juice in moderation, which is helpful for digestion, moistening intestines and supplementing the lack of nutrition in diet.

If adults can't ensure a reasonable diet, it is also a good way to supplement some nutrition by drinking fruit juice. Some people don't like drinking boiled water. Sweet fruit juice can increase their water consumption and ensure their body's need for water, which is really a good thing.

Fruit juice retains a lot of nutrients in fruit, such as vitamins, minerals, sugar and pectin in dietary fiber, and its taste is better than ordinary boiled water. Compared with water and carbonated drinks, fruit juice does have considerable advantages. However, most fruit juices are "delicious" because they are flavored with sugar, sweeteners, sours, spices and other ingredients.

Need to remind everyone that there is a considerable gap between the nutrition of fruit juice and fruit, so don't confuse the two, fruit juice can't completely replace fruit. First of all, there is basically no cellulose in juice; Second, the process of crushing and pressing destroys some vitamins that are easy to be oxidized in fruits; Thirdly, the lack of some nutrients (such as cellulose) in fruits will adversely affect the overall nutritional function; Fourthly, in the process of fruit juice production, some additives will inevitably affect the nutritional quality of fruit juice, such as sweeteners, preservatives, coagulants to clarify fruit juice, additives to prevent fruit juice from discoloring, etc. Fifth, the sterilization method of heating will also destroy the nutritional components of fruits. Therefore, for those who can eat fresh fruit, the whole fruit is always the best choice in nutrition.

Eating and drinking juice is learned.

Because people seldom eat vegetables and fruits for breakfast, it should be a good habit to drink a cup of freshly squeezed juice or pure juice in the morning to supplement the water and nutrition needed by the body. Unfortunately, people often drink a glass of milk and can't drink anything else. It should be noted that don't drink juice with high acidity on an empty stomach, and eat some staple food before drinking to avoid gastrointestinal discomfort. Whether it is freshly squeezed juice, pure juice or juice drink, drink as little as possible at lunch and dinner. The acidity of fruit juice will directly affect the acidity of gastrointestinal tract. A large amount of fruit juice will dilute the concentration of gastric digestive juice, and the fruit acid in fruit juice will also combine with some nutrients in the diet, which will affect the digestion and absorption of these nutrients, making people feel full when eating, unable to eat, indigestion after meals, and stomach discomfort. Besides breakfast, it is also suitable for drinking juice between meals.

Distinguish the kinds of juice

Usually we can buy the following kinds of juices in the market:

First, fresh fruit juice in fresh packaging. Generally, it is stored in plastic bottles or box-shaped paper, which means that the storage condition is cold storage, and the storage time is short, mostly only 7- 10 days. This kind of juice is generally freshly squeezed juice, which has not been sterilized at high temperature, and basically does not add sugar, sweeteners and preservatives, and its nutrients are well preserved. This kind of fruit juice must be stored at low temperature and drunk in a short time, and its shelf life is short, so it is rare in the market.

Second, pure juice. Cartons, glass bottles and plastic bottles are generally used, and the storage time at room temperature is more than half a year. This kind of juice is mostly concentrated juice produced in the fruit producing area, which is reduced to the original juice concentration by adding water and then sterilized at an instant high temperature. Nutrients, especially vitamins, have been lost, and the flavor of fruits has changed slightly. The concentration of this juice should be the same as that of freshly squeezed juice, or at least similar.

Third, concentrate the juice. Glass bottles or plastic bottles are often used and can be stored at room temperature for a long time. This fruit juice contains a lot of sugar and additives, and the dilution ratio will be indicated on the label when drinking. Concentrated fruit juice is easy to carry, generally has high sweetness, and its taste can be adjusted by itself.

Fourth, fruit juice drinks. There are many kinds of juice drinks with steam and juice drinks without steam, and the content of juice is different.
