Advantages and disadvantages of drinking fresh fruit juice frequently; Nutritional value of fruit juice
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, but fruit juice can't completely replace fruit.
Old people and children drink a small amount of fruit juice properly, 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. But why do most fruit juices? Does it taste good？ It is the result of adding sugar, sweeteners, sour materials, spices and other ingredients to taste.
Disadvantages of fruit juice
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.
Under what circumstances should the fruit be juiced to extend the shelf life?
During the storage of fruit juice, the fastest loss of nutrients is vitamins. Because vitamin C likes acidic environment and is the most stable in acidic environment, the stronger the acidity of fruit juice, the longer the vitamin C will be preserved.
Fast-paced life
In life, if it is inconvenient to chew fruits often because of the rush of time, oranges, grapes, kiwis and other fruits with high acidity can be made into juice to drink. Relatively speaking, the loss of vitamin C is less.
