To stay healthy and productive, our bodies need over 114 vitamins and minerals that can only be obtained through a varied diet. Eating the same foods every day does not provide this variety of nutrients. It is important to eat a wide range of foods from all food groups throughout the day and week, such as fruits for breakfast, vegetables for lunch, and protein for dinner, in order to meet all of our nutritional needs and avoid deficiencies that can cause fatigue, headaches and loss of focus. Consuming a variety of nutrients is as important for our bodies as putting different fuels and fluids in a car to keep it running well.
