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 through the body by what method?– being dissolved in water
• Some people believe that if small doses of vitamins are good for you, more is better. Too few vitamins keep the body from what?– from operating at full capacity
• Too many vitamins may be damaging to your health – toxic.– Just as too much gasoline in a fuel tank, too many
vitamins will be excreted or stored and an excess can be toxic.
