Title: Vitamins, Minerals and Water


1
Vitamins, Minerals and Water
2
Objectives
  • Identify the two main classes of vitamins
  • List seven minerals your body needs in
    significant amounts
  • Explain why water is so important to your body

3
Vocabulary
  • Vitamin-
  • A nutrient that is made by living things, is
    required in small amounts, and assists in
    chemical reactions in the body
  • Antioxidant-
  • A vitamin that helps protect healthy cells from
    the damage caused by the normal aging process as
    well as from certain types of cancer
  • Mineral-
  • A nutrient that occurs naturally in rocks or
    soil, needed by the body in small amounts

4
  • Anemia
  • A condition in which the red blood cells do not
    contain enough hemoglobin
  • Homeostasis
  • The process of maintaining a steady state inside
    the body
  • Electrolyte
  • A dissolved substance that regulates many
    processes in cells
  • Dehydration
  • A serious reduction in the bodys water content

5
Vitamins
  • Unlike carbs, fats and proteins vitamins do not
    directly provide you with energy or the raw
    materials of which your cells are made
  • Vitamins help the body with various processes,
    including the use of other nutrients
  • Vitamins play roles in chemical reactions in the
    body. example vitamin K helps your blood clot
    when you get a cut or a scrape

6
  • Your body is able to make some vitamins
  • Example your skin manufactures vitamin D when
    it is exposed to sunlight
  • However, most vitamins must be supplied in the
    food you eat
  • 2 classes of vitamins Fat-soluble vitamins
    (which dissolve in fatty materials) and
    water-soluble vitamins (which dissolve in water).

7
Fat-Soluble Vitamins(Can be stored by the body)
  • Vitamin A Found in Liver eggs cheese milk
    yellow, orange and dark green vegetables and
    fruit
  • Vitamin D- Found in Milk eggs liver exposure
    of skin to sunlight
  • Vitamin E- Found in Margarine vegetable oils
    wheat germs whole grains legumes green, leafy
    vegetables
  • Vitamin K- Found in Green, leafy vegetables
    potatoes liver made by intestinal bacteria

8
Fat-Soluble Vitamin Functions
  • Vitamin A- Maintains healthy skin, bones, teeth
    and hair aids vision in dim light
  • Vitamin D- maintains bones and teeth helps in
    the use of calcium and phosphorus
  • Vitamin E- Aids in maintenance of red blood
    cells, vitamin A, and fats
  • Vitamin K- Aids in blood clotting

9
Water Soluble Vitamins (Cannot be stored by the
body)Therefore, it is important to eat foods
that supply them every day
  • Vitamin B1 (Thiamin) pork products liver
    whole-grain foods legumes
  • Vitamin B2 (Riboflavin) Milk eggs meat whole
    grains dark green vegetables
  • Vitamin B3 (Niacin) Poultry meat fish whole
    grains nuts
  • Vitamin B6 (Pyridoxine) meat poultry fish
    whole-grain foods green vegetables

10
  • Vitamin B12 (Cobalamin) meat fish poultry
    eggs milk cheese
  • Pantothenic acid organ meats poultry fish
    eggs grains
  • Folate (folic acid) green, leafy vegetables
    legumes
  • Biotin- organ meats poultry fish eggs peas
    bananas melons
  • Vitamin C (Ascorbic acid) citrus fruits green
    vegetables melons potatoes tomatoes

11
Water-Soluble Vitamin functions
  • Vitamin B1 (Thiamin) Aids in carbohydrate use
    and nervous system function
  • Vitamin B2 (Riboflavin) Aids in metabolism of
    carbohydrates, proteins and fats
  • Vitamin B3 (Niacin) Aids in metabolism
  • Vitamin B6 (Pyridoxine) Aids in metabolism of
    carbohydrates, proteins and fats

12
  • Vitamin B12 (Cobalamin) Maintains healthy
    nervous system and red blood cells
  • Pantothenic acid Aids in metabolism
  • Folate (folic acid) Aids in formation of red
    blood cells and protein
  • Biotin- Aids in metabolism
  • Vitamin C (Ascorbic acid) Aids in bone, teeth,
    and skin formations, resistance to infection,
    iron uptake

13
The 7 minerals you NEED in significant amounts
  • Calcium
  • Sodium
  • Potassium
  • Magnesium
  • Phosphorus
  • Chlorine
  • Sulfur

14
Water
  • About 65 of your body weight is water
  • Water is essential for all life processes
  • Almost all of the bodys chemical reactions take
    place in a water solution
  • Water is the primary component of blood and
    tissue
  • It carries dissolved waste products out of the
    body and helps digest food

15
What roles does water play in homeostasis?
  • Water regulates body temperature
  • When you become overheated, your body excretes
    perspiration, which cools your body
  • Water contains dissolved substances called
    electrolytes that regulate many processes in your
    cells

16
Dehydration
  • 2 causes of dehydration very heavy perspiring
    and severe diarrhea
  • When the body is dehydrated it loses important
    electrolytes along with the water
  • Symptoms weakness, rapid breathing, and a weak
    heartbeat

17
How much water?
  • Females age 14-18 Everyday you need at least ten
    8-ounce cups of water
  • Males age 14-18 Everyday you need at least
    fourteen 8-ounce cups of water
  • Foods that contain a lot of water fruits and
    vegetables or juices
  • Drinks that contain caffeine- may not be a good
    source of water for your body
