So I think the difference between fruit juice and fruit lies in freshness, and the freshness also determines the nutritional value they can provide to the human body. Just like apples, the taste after squeezing is far worse than that of fresh apples, and some nutrients are lost in the chemical reaction in this process.
The basic nutrition of fruit juice exists, and some trace elements such as vitamin C, protein and carbohydrates are not as rich as fresh fruits. So don't drink water with fruit juice, it's better to eat fruit.
