Fruits and veggies are good for your body and for your skin as well, as a lot of other people have said already. It's good that you're drinking lots of water -- keep doing that! It flushes out the toxins in your body, including your skin. 8 glasses a day should do it...I usually drink 2-3 half liter bottles.
Other tips to clear skin include getting lots and lots of rest. Some of us unfortunately break out when we go out and party all night and go to bed at 3am (me!) Alcohol is definately not good for your skin, so steer clear.
Although some say that greasy foods don't cause skin to break out, I would steer clear from it anyway. Nobody looks or feels their best when they are bloated and sluggish. Stay away from chips, pre-packaged foods...try to eat fresh ingredients as much as possible. So by eating foods like nuts, chicken (grilled is the best), fruits and veggies.
I have yet to resume my healthy diet
I noticed that my skin was a lot better when I exercised and ate well as compared to now, where I've gotten lazy and not worked out for weeks and eaten tons of cup noodles...
