Key components include fruits and vegetables, which are rich in vitamins and minerals; whole grains, which provide energy and fiber; protein sources such as lean meats, fish, eggs, beans, and nuts; and dairy products for calcium. It's important to limit the intake of sugary snacks, beverages, and processed foods to maintain energy levels and overall health.
