Eating healthier.

So I have completely cut soda out of diet. It wasn't hard I realized I hadn't drank it for a week and figured I might as well just cut it out completely and I'm drinking more water now. Doing this has made me want to eat healthier as well. Anyone have any tips on how to do that and where to start? I have been eating fruit more instead of the junk food but that's about it. Any advice is much appreciated!
