Food when cycling

What good is best when cycling? I say it depends on the distance. On a short club ride foe few hours and often fast carbohydrates are great and good to have 2 water bottles 1 with water and 1 with electrolyte like Gatorade. You can use this system even on a century ride. But on double century or day after day touring you can not use this carb diet. On long rides you deed solid food rich of proteins and even fats. Carbs are ok too but in lower quantities. Steaks. Full English breakfasts are great. Muscle milk is ok too but I prefer natural foods.
