Listen carefully to the following passage:
In today's lecture, we will be discussing the various elements that make up a healthy diet. A balanced diet includes a variety of food groups to ensure that our bodies receive adequate nutrients. First, fruits and vegetables should occupy a significant portion of our plates. They provide vitamins, minerals, and fiber that are essential for maintaining good health. Next, whole grains, such as brown rice and whole wheat bread, are vital sources of energy and should also be included. Additionally, it is important to consume lean proteins, such as chicken, fish, beans, and nuts, to support muscle repair and growth. Lastly, don't forget healthy fats found in sources like avocados and olive oil, which are important for heart health. In summary, a well-rounded diet consists of colorful fruits and vegetables, whole grains, lean proteins, and healthy fats, all of which contribute to overall well-being.
