Carbohydrates
  • Starches and sugars
  • 4 calories in 1 gram of carbohydrate
  • Preferred source of energy
  • Simple
  • Sugars (fructose, glucose)
  • Complex must be broken down into simple before
    they can be used
  • Starches (whole grains, seeds, legumes)

7
Carbs continued
  • When excess carbohydrates are present, the body
    converts them and stores them as body fat
  • Essential for athletic ability
  • Dietary fiber
  • Complex carbs
  • Made mostly of plant material that cannot be
    absorbed by the body

8
Fiber
  • Indigestible complex carb
  • Vegetables, fruits, and whole grains
  • Helps move waste through digestive system

9
Proteins
  • Nutrients that help build and maintain body cells
    and tissues
  • All proteins are made of 20 amino acids
  • Complete
  • Good amounts of all 9 essential amino acids
  • Animal products
  • Incomplete
  • Lack 1 or more essential amino acids
  • Beans, peas, whole grains

10
Proteins continued
  • Builds new cells and tissues
  • Most important function is role in growth and
    repair of bodily tissues
  • Make enzymes, hormones and antibodies
  • Supply body with energy
  • 3rd energy source
  • Bodys building block
  • There are 4 calories per gram of protein

11
Fats
  • Fatty substance that does not dissolve in water
  • Needed for proper body functioning
  • 2nd fuel source in the body
  • Essential fatty acids
  • Fatty acids the body needs but cannot produce

12
Fats continued
  • Saturated
  • Usually solid at room temperature
  • Animal fats and tropical oils
  • High intake is associated with increased risk of
    heart disease
  • Unsaturated
  • The preferred fat
  • Usually liquids at room temperature
  • Associated with a reduced risk of heart disease

13
Cholesterol
  • Circulates in blood
  • Amount it makes is used to make cell membranes
    and nerve tissue, hormones, vitamin D and bile
  • Excess blood cholesterol is deposited in arteries
    increases the risk of heart attack
  • May be hereditary

14
Cholesterol Continued
  • Produced in liver
  • No more than 3x the amount of LDL vs HDL
  • HDL good
  • Provides SOME protection against heart disease
  • LDL bad
  • Carries cholesterol and other fats through blood

15
Vitamins
  • Help regulate vital body processes
  • Needed for growth and maintenance
  • Needed for the utilization and absorption of
    nutrients
  • Water soluble
  • Dissolve in water
  • Pass easily through blood during digestion
  • Fat soluble
  • Absorbed, stored and transported in fat
  • Stored in fatty tissue, liver and kidneys
  • Excess can be toxic

16
Minerals
  • Substances that the body can not produce but are
    needed for forming healthy bones, teeth and
    regulating vital body processes
  • Comes from plants
  • Disease can result from a lack of minerals
  • Minerals help with bone and teeth formation and
    strength, muscular development, blood formation,
    and water balance
  • Calcium, Phosphorus, Magnesium, Iron

17
Water
  • Transports nutrients to and carries wastes from
    your cells, make up blood and control body
    temperature
  • Lubricates joints and membranes
  • At least 8 cups of water each day
