Vigorous Vitamins
Ummm….like Powdered Toast Man!
What are vitamins?
Glad you asked!!!
Vitamins are organic
chemicals,
substances that
contain carbon,
hydrogen, and
oxygen.
Where do Vitamins come from?
Vitamins occur naturally
in all living things,
plants and animals
alike: flowers, trees,
fruits, vegetables,
chickens, fish, cows—
and you.
I’m glad you asked
that too!
Your body needs at least 11
specific vitamins
How will I ever
remember all those?
I mean a list of all the
vitamins and what
each one does would
be hard to
remember…
Yep…that looks really hard…
Don’t worry…be happy…
You don’t need to memorize the whole list, but
there are some things you should know.
Vitamins are classified as either
FAT SOLUBLE:
WATER SOLUBLE:
Dissolve in fat.
Dissolve in water.
If you consume larger
If you consume too
amounts of fat-soluble
many water-soluble
vitamins than your
vitamins, you just pee
body needs, this
them out.
could cause
problems.
All Dogs Eat Kidneys
That’s how you can remember the fatsoluble vitamins.
Vitamins A, D, E, and K dissolve in fat.
Vitamin A and Vitamin D
Vitamin A:
Keeps skin smooth and
supple
Helps with vision
Vitamin D:
Helps your body absorb
calcium which makes
strong bones and
teeth
Help! I Seem to be Turning a
Strange Color!!!!
Another form of vitamin A (Carotenoid) is not
stored in your liver and cannot build up to
toxic levels. BUT if you eat too much
Carotenoid (found in carrots and
tomotatoes)
Your skin will turn ORANGE
Could be a good Halloween Costume
Vitamins E and K
Vitamin E
Healthy reproductive
system, nerves,
muscles.
Anti-oxidant.
Vitamin K
Makes specialized
proteins found in
blood plasma.
Makes bones and
kidney tissue.
Anti-Oxidants…What are They?
They prevent a
chemical reaction
called oxidation.
They stop molecular
fragments called free
radicals from joining
together to form
potentially cancercausing compounds
in your body.
How they work…

Anti-Oxidants are good because…
They slow normal wear and tear on body
cells.
They may reduce and risk of heart disease
and some cancers.

Digest carbohydrates and proteins
Grow properly and normally
Heal wounds
Make healthy red blood cells
These are some of the things that Vitamin B
help your body do.
Wild Applause for Vitamin B!
Vitamin Deficiencies
The good news is that vitamin deficiencies
(not getting enough of a particular vitamin)
are rare among people who have access
to a wide variety of foods and know how to
put together a balanced diet.
Scurvey: Vitamin C Deficiency
• Scurvy leads to the
formation of spots and
bleeding on the skin, and
spongy gums.
• A person with the ailment
looks pale, feels
depressed, and is
partially immobilized.
• In advanced scurvy there
are open, wounds and
loss of teeth.
Scurvey…Scourge of the Sea
Scurvy was at one time
common among sailors
and pirates who sailed for
longer than perishable
fruits and vegetables
could be stored.
.
Scurvy was one of the
limiting factors of marine
travel, often killing large
numbers of the
passengers and crew on
long-distance voyages.
Big Trouble. Vitamin Megadoses
• Can’t get too much of a good thing?
• WRONG!!!
• Some vitamins are TOXIC when taken in
the very large amounts popularly known
as MEGADOSES.
But unless you are taking
VITAMIN SUPPLEMENTS
It is pretty much impossible to cram
down enough food to overdose on
Vitamins D, E, K, C and all the B’s.
Liver and Fish Oil
Contain concentrated forms of Vitamin A.
Liver contains so much Vitamin A that early
20th century explorers to the South Pole
made themselves sick on seal and whale
liver.
Children fed daily servings of chicken liver
have reached toxic levels of Vitamin A.
Where do I get my vitamins?
Most people who eat a healthy varied diet
will get enough vitamins and do not need
to take vitamin supplements.
Eat this:
Not this:
But if you are vegan…
That is, if you do not eat any food from
animals (including milk, cheese, eggs and
fish oils), Vitamin D, C, and B12 should be
supplemented.
