Should i drink or eat more fruit to avoid constipation?

Constipation: Drink well 2 liter/d and eat fiber fruits (there are fruits without fiber) + lifestyle changes = increased activities on daily basis if you are not active daily yet +hard fruits such as apple-pears + nuts (all nuts had protein equal in weight as meat + hi content of fiber) + beans (all kinds of bean) promote bowel movements and lose weight by better diet. If still constipated, see doc asap.

Yes: The cardinal rules for beating constipation naturally are keep hydrated ( drink enough water in diet) and eat plenty of fresh fruits and vegetables. Increasing fiber will also help, but only if you drink menough extra water to allow the fiber to work.

Depends: Some fruits like apple will constipate you while others, the "P's" usually help. (Peaches, pears, prunes, pineapples). In an odd turn about apple juice is helpful, as are most fruit juices & better hydration in general. If you take in enough fluid value to need to pee at least every 4-6 hours it should be more than adequate.
