A normal healthy diet contains all the macronutrients(Protein, Carbohydrates & Fat), Vitamins(A, B, C, D, E, K) and Minerals(Calcium, Copper, Iron, Zinc etc) in the right amount. The right amount depends on your weight, height, age etc. You can use tools like Cron-O-Meter to track your meals and figure out what you are getting enough of and what not. You also need plenty of water along with balanced diet.
