IF I eat a lot of fruit instead of other solid foods will it affect me any?

Okay, so I am going to visit my family in Mexico in 3 days (which I am so excited for!!) and my gmas yard is just FULL of fruit plants....and her yard is really big also. She has LOTS of mangos, oranges, mandarines, grape fruits, and she has another fruit that I have no idea what its called in english lol. I usually live off of these fruits when I go down there..so if I eat them for lunch and dinner instead of other food like idk..beans..burritos..etc..will it affect me any? Like my diet? I mean, I usually DO eat that fruit instead (cuz its sooooo good haha) but I just thought I would know. Well thanks in advanced for you guys that will answer this:)
