-Eating a variety of foods and choosing the appropriate number of servings from the food guide pyramid is something that many people do not do.
-No two food items provide the exact same nutrients and this is why it is important to eat an assortment of foods. This means that some food items are better sources for nutrients than other items and vise versa.
-Balance and moderation are also important aspects of daily intake of food. Balance compares with variety because of the importance of eating a balanced diet from the Food Pyramid.
