State how individuals can live a healthy life by having a balanced diet and regular exercise.

A balanced diet includes proteins, a wide variety of fruits and vegetables (of various colors), whole grains, and limited fats and sugars. It is also important to get enough exercise. You can do this by walking at a moderate pace, running, playing sports, swimming, or doing anything that raises your heart rate like climbing stairs. You should aim to exercise at least 3-5 days per week for at least 30 minutes at a time.
