Two year olds are often picky eaters, but you can allow them to eat as much of their favorite fruits and vegetables as they want at mealtimes and for in between meal snacks. Cereals and whole grain bread should be staples on their diets, at least two servings per day. Two or three glasses of real fruit juice a day is fine. Protein can be given in the form of fresh (not processed) meats, eggs, peanut butter (if not allergic), cheese and milk - this would fulfill the protein requirements. Encourage the toddler to drink water.
