A balanced diet includes a variety of foods from six nutrient groups consumed regularly. It is recommended to eat five meals a day - breakfast, two snacks, lunch, and dinner - with breakfast being the most important. Eating a balanced diet with five meals per day constitutes a healthy diet. Maintaining good eating habits includes washing hands before eating, sitting properly while chewing food slowly, and brushing teeth after meals. To be healthy, one should follow a balanced diet, avoid unhealthy foods, and do regular exercise.
