Ice cream is great for putting on fat. Fruits are good. Especially post workout. But eat them in moderation. The carbs from fruits are high GI. Tuna is a great source...I have at least a can a day. Lots of granola bars contain lots of High Fructose Corn Syrup, which is no good...so read the labels. Eat plenty of green vegetables...there is a sticky in the nutrition forum that will help you to choose what to eat.
