Nutritional Chemistry
Dietary Minerals

Dietary Minerals
  • Minerals are increasingly recognized as being
    important in both the short and long term health
    of people.
  • Dietary Minerals are divided into two classes
  • Major minerals
  • Trace minerals

? The difference between the two classes are
the amount of the mineral one needs to consume
daily.

Dietary Minerals
  • Major Minerals
  • Calcium
  • Sodium
  • Potassium
  • Chlorine
  • Magnesium
  • Phosphorous
  • Sulfur
  • Trace Minerals
  • Iron
  • Chromium
  • Zinc
  • Selenium
  • Cobalt
  • Copper
  • Nickel

Calcium
  • Calcium is a metallic element and is found
    naturally in the Earths crust in the
    abundance of 3
  • It is Never found naturally in an uncombined
    state!!
  • 99 percent of the calcium in the body is found
    in the bones
  • 1 percent found in the blood and soft tissues
    (muscle and nerves)

5
Functions of Calcium in the Body
  • Essential for bone mass and proper structural
    support of the body
  • Essential for proper blood clotting
  • Necessary for transmission of nerve impulses
  • Needed for Muscle contraction
  • Essential to control metabolic reactions in all
    cells

6
Sources of Calcium
The best sources of calcium are milk and other
dairy products.
Examples milks, cheeses, yogurt
The second largest source of calcium is
found in leafy green vegetables.
Examples spinach, kale, mustard greens

Calcium Deficiency
  • When the body does not receive enough calcium, it
    will take the necessary calcium directly from the
    bones.
  • If this process continues over time, the bones
    will become depleted of calcium producing the
    condition of Osteoporosis
  • Osteoporosis is literally translated to mean
    porous bones
