Proteins • Nutrients that help build and maintain body cells and tissues • Made of long chains of amino acids • Used to make enzymes, hormones and antibodies • Supply body with energy

Fats • Lipid – fatty substance that does not dissolve in water • Some fat is necessary for good health • Types: – Saturated – solid at room temperature – Unsaturated – liquid at room temperature

Role of Fats • • • Provide a concentrated form of energy Transport vitamins in blood stream Needed for growth and healthy skin Add flavor and texture to foods Help satisfy hunger longer Consuming excess can result in weight gain and obesity

Common Vitamins • C – protects against infection • A – keeps eyes moist and adjusts to darkness • D – bone and tooth development • Folic Acid – needed for cell replication and growth

Minerals • Substances that the body cannot manufacture • They are needed for: – Forming healthy bones and teeth – Regulating many vital body processes

Common Minerals • Calcium – building bones and teeth • Iron – important for red blood cell function • Phosphorous – gives rigidity to bones, maintains p. H balance in blood and essential in cell metabolism • Magnesium – aids in bone growth and muscle contraction
