Why are nutrients important? The next 2 weeks I will review basic information on nutrients and their importance. Nutrients in food are needed for building and repairing body tissues. They are also used for regulating body processes such as digestion, energy, and muscle contraction. In addition, food is the primary source of energy for the body.
Nutrient and energy requirements for people differ depending on age, gender, body size, activity level, metabolic rate, and other factors such as pregnancy. There is no single ideal food plan for everybody. Standards have been developed to specify the nutrient intake levels considered to be adequate to meet the needs of healthy people. These standards are called the Dietary Reference Intakes or Daily Values. The best way to meet your needs is through a well balanced diet.
