Many people think that fruit juice can replace fruit. Drinking fruit juice can supplement nutrients in fruit. In particular, children who do not like fruit should drink more, or even completely replace drinking water. In fact, this is not the case. The following Xiaobian will tell you in detail.
First, juice can not replace fruit
The elderly and children drink a small amount of juice can help digestion, moisten the intestines, and supplement the lack of nutrients in the diet.
If adults can not guarantee a reasonable diet, it can be considered a good way to add some nutrition by drinking juice. Some people do not like to drink boiled water. The sweet-tasting juices can increase their drinking water and ensure the body's need for water. It is indeed a good thing. Fruit juice retains a lot of nutrients in fruits, such as vitamins, minerals, sugars, and pectin in dietary fiber, and tastes better than ordinary boiled water. Compared to water and carbonated drinks, juice does have a considerable advantage.
However, the reason why most fruit juices are “drinking†is because of the addition of seasonings such as sugar, sweeteners, sour materials, and spices. Need to remind everyone is: There is a considerable gap between the nutrition and fruit juice, do not confuse the two, fruit juice can not completely replace fruit.
First of all, the fruit juice contains essentially no cellulose in the fruit;
Second, the process of mashing and pressing causes some of the easily oxidized vitamins in fruits to be destroyed;
Third, the absence of certain nutrients in fruits can have an adverse effect on the overall nutritional effect.
Fourth, some additives in the process of fruit juice production are bound to affect the nutritional quality of fruit juices, such as sweeteners, preservatives, coagulants that make the juice clear, and additives that prevent juice from discoloring;
Fifth, the heated sterilization method also damages the nutrients of the fruit. Therefore, for people who can eat fresh fruits, the whole fruit is always the best choice for nutrition.
Second, drink fruit juice when learning
Because people rarely eat vegetables and fruits for breakfast, drinking a glass of fresh juice or pure juice in the morning should be a good habit to supplement the body's needs for water and nutrients. Unfortunately, people often drink a glass of milk and cannot drink anything else.
It should be noted that when fasting, do not drink fruit juices with higher acidity, eat some staple foods and drink again to avoid stomach discomfort. Whether it is fresh fruit juice, pure juice or fruit juice drinks, drink as little as possible during lunch and dinner. The acidity of the juice will directly affect the acidity of the gastrointestinal tract. A large number of juices will dilute the concentration of the gastric juice. The fruit acids in the juice will also affect the digestion and absorption of these nutrients in combination with certain nutrients in the diet. At the time of eating, I felt that my stomach was full, I couldn’t eat it, I couldn’t eat well after my meal, and my stomach was not feeling well. In addition to breakfast, fruit juice is also suitable for drinking between meals.
Third, distinguish the types of juice
Usually the juices we can buy in the market are the following:
1. Fresh fruit juice
Generally used plastic bottles or house-type paper-made fresh box, indicate the preservation conditions are low-temperature refrigeration, the preservation time is short, most of them only 7-10 days. This kind of fruit juice is generally fresh squeezed juice, which has not been sterilized by high temperature, and basically has no added sugar, sweeteners and preservatives, and the nutrient composition is well preserved. The fruit juice must be stored at low temperature and be consumed within a short period of time. Due to the short shelf life, it is rare in the market.
2, pure juice
General use of carton or glass bottles, plastic bottles, room temperature for more than six months. Most of the fruit juices are concentrated juices produced from fruit production areas and the concentration of the original juices is restored by adding water, and the instant high temperature sterilization treatment is performed. Nutrients, especially vitamins, are lost, and the flavor of the fruit is slightly altered. The concentration of this juice should be the same as that of freshly squeezed juice, at least similar.
3, juice concentrate
Multi-purpose glass bottles or plastic bottles, longer storage time at room temperature. This juice contains more sugar and additives, and the label will indicate the dilution when drinking. Concentrated fruit juices are easy to carry, sweetness is generally higher, and taste can be adjusted by itself.
4, juice drinks
There are many varieties of steamy fruit juice beverages and non-steamed juice drinks, and the content of juices is not the same.
