Nutrients Carbohydrates : main source of energy for the body. Includes sugars, starches and fiber. Sources of carbs include veggies, beans, potatoes, pasta, breads, rice, bran, popcorn and fruit. Simple carbs contain sugar Excess carbohydrates are stored as fat.
Nutrients continued Proteins : – Needed for growth, to resist infection – to build, repair and maintain body tissues, – to regulate body processes – to supply energy to maintain strength – Examples: meat, fish, poultry, milk, yogurt, eggs, dried beans, whole grains, pasta, corn, nuts, seeds – Excess protein is burned as energy, stored as fat
Nutrients continued Fats : provides energy and helps the body store and use vitamins – The body needs fat to maintain body heat, energy reserve & build brain cells & nerve tissue – Examples: oils, butter, margarine, nuts, salad dressing, meat, egg yolks, ice cream, milk, cheese
Nutrients continued VitaminsMinerals helps the body use carbohydrates, proteins and fats Vitamins- in all food groups Fat soluble vitamins dissolve fats, stored in the body (A, D, E, K) used for eyes, teeth, bones, hair, cells, blood clotting Water soluble vitamins cannot be stored by the body (B complex & C) used for function of nerve cells Regulates many chemical reactions in the body Minerals are found in all food groups Macro: calcium & sodium (large amounts needed) Trace: iron & zinc (small amounts needed)
Nutrients continued Water : involved with all body processes, makes up basic part of the blood, helps with waste removal, regulates body temperature, cushions the spinal cord and joints Need 6-8 glasses daily Carries nutrients to all body cells Carries waste products from cells to the kidneys Water leaves the body in the form of perspiration and urine
