Vitamins Study Guide
• Vitamins are found in nearly all the foods
on My Pyramid
• Vitamins do not provide energy
• but they are essential because they
regulate the body chemistry and body
functions
• Vitamins cannot be produced by our
bodies.
• They must be ingested or eaten in our
food.
• Vitamins assist the body in using food by
bringing about biochemical reactions so
life can be maintained
• Vitamins are divided into two groups:
– 1. fat-soluble
– 2. water-soluble
• Examples are:
– 1. Fat-soluble - A, D, E, K
– 2. Water-soluble - C, B complex, Folacin
• Fat-soluble vitamins are transported
through the body by what method?
– being carried and stored in fat
• Water-soluble vitamins are transported

• Some people believe that if small doses of
vitamins are good for you, more is better.

• Too many vitamins may be damaging to your

– Just as too much gasoline in a fuel tank, too many
vitamins will be excreted or stored and an excess can
be toxic.
