Eating a variety of foods and maintaining an energy balance are basic guidelines for a healthy diet. Good nutrition is not complicated for those who understand dietary guide-lines. To be properly nourished, you should regularly eat a wide variety of foods from the major food groups, selecting a variety of foods from within each group. A well-balanced diet provides all the nutrients needed to keep one healthy. Most healthy adults do not need vitamin or mineral supplements if they eat a proper variety of foods. There are no known advantages in consuming excessive amounts of any nutrient, and there may be risks in doing so. For you to get enough fuel from the food you eat and to obtain the variety of foods needed for nutrient balance, you should eat three meals a day.
