I don't like either of them. I like to eat sugar cane piece directly. That will help our teeth to get strengthened. In fact, juices are not good. It is always better to have the fruit or fruit piece directly. This will help us in getting some fibre also which will ensure better digestion. So I always take fruits than fruit juices.
Fruit juices are better than artificial cool drinks. If you have a choice between these two you should go for fruit juice. If you have a choice between fruit and fruit juice, you should prefer fruit only. This is the best way to have good health and stamina.
