              Deep Thoughts

   If your body could talk, what would it
    say about you?

What food would you be if
you are what you eat?
What are NUTRIENTS?

   Substances in food that our body needs to
    function.
   Six groups:
    –   Protein
    –   Carbohydrates
    –   Fat
    –   Vitamins
    –   Minerals
    –   Water
The body uses nutrients to. . .


   Provide energy.
    (calorie=unit of energy from food)
    fat, carbohydrates, protein
   To build and repair cells.

   To regulate body processes.

      Function of
      Healthy Fat
(Unsaturated and Some Saturated)


  –   Maintain body temperature
  –   Secondary source of energy
  –   Keeps you full longer
  –   Helps balance blood sugar
  –   Supports brain (2/3 fat) and nervous system function
  –   Protect body tissues and organs
  –   Plays an essential role in carrying the four fat-soluble
      vitamins: A, D, E, and K.

       • Excess calories from protein and carbohydrates are
         converted to and stored as fat. If you are eating mostly "fat
         free" foods, excess consumption will result in additional
         body fat.
              Avoid Trans Fats
          hydrogenated or partially hydrogenated oils
              AHA limits to less than 1 gram daily
   Damages cell               Found in processed & fast
    membranes                    food:
   Leads to:                      fast foods
     – high cholesterol            cereals
     – clogged arteries            breads/ crackers
     – cancer                      box meals
     – depression                  cake
     – heart disease               cookies
     – autoimmune disease          margarine
     – poor memory/learning  frozen pizzas
             *FDA- less than .5g can claim
      “0g trans fat” on food label- DECEIVING!
             Protein-4 cal/g
         10-20% of daily calories
Functions in the body:
   Is found in every cell of the
    body.
   Used to build new cells and
    repair injured cells.
   NOT the body’s first source
    of energy.
   Boosts metabolism by up to
    30% if eaten in small
    portions several times a day
   Supplies energy when there
    is not enough fat or
    carbohydrates for the body
    to use
          What is protein made
Protein    of?

             Composed of
              amino acids
              (building blocks).
             There are 22 amino
              acids; 8 of which
              the body cannot
              manufacture, and 14
              which the body can
              produce.
   Complete proteins      Protein
    contain all 8
    essential amino
    acids. They are
    foods which come
    from animals.
   This includes steak,
    pork, chicken,
    turkey, fish, eggs
    and dairy products.
Protein
   Incomplete proteins lack
    one or more of the
    essential amino acids.
   This includes pinto beans,
    kidney beans, split peas,
    lentils, rice, corn tortillas,
    peanut butter, and nuts.
   Vegetarians need to eat a
    variety of food in order to
    get all their essential
    amino acids
Protein Needs
  Protein is essential for building and maintaining muscle
 tissue as well as for muscle recovery, immunity and even
  bone health . The body needs protein to help your active
 muscles stay stong and healthy. Individuals need 0.55 - .80
        grams of protein per pound of body weight
So a 120lb woman should try and consume between 66 and
  96 grams of protein daily. (depending on activity level)
                     Protein Suggestions:
                        Serving Size       Protein (Grams)
         Lean Sirloin Steak       4.0 oz.         34
         Chicken Breast,         3.5 oz          24.3
         Yogurt                  1 cup            10
          Egg                    1 Large          6.5
Eating Too Little Protein:
   Imbalance or               –   insomnia
    deficiency of              –   anorexia
    neurotransmitters          –   chronic pain
    (brain chemicals ie:       –   migraines

    foods.
