It is better to eat whole fruit than to drink juice, and it is better to eat vegetables than to drink vegetable juice. In addition, the salt content of vegetable juice is also high. This grade of drinks can be drunk properly when necessary, but it is not a daily necessity. Grade 6: sweet drinks with calories.
