How old do you gota be to drink apple juice?

You should limit a toddler, or any child's daily intake of fruit juice. It can lead to cavities, and more commonly, increased weight. Some doctors advise patients to drink juice to prevent constipation, however in general I wouldn't recommend more than 1 glass of juice a day and instead would recommend drinking orange juice because it has more vitamins and calcium.

Furthermore, I would recommend it is diluted juice (half water, half juice).
