-Osteoporosis (calcium), osteoarthritis (cartilage wears in spine), cancers
(energy) carbohydrates, lipids and proteins. They are required
in relatively large amounts.
are composed of carbon, hydrogen and oxygen. They
are the primary energy source of the human body, particularly for the
brain. They have 4kcal per gram
provide us with fat-soluble vitamins and essential fatty acids in
addition to storing large quantities of energy. Main energy source for
body, important at rest and during low-intensity exercise. Composed of
carbon, hydrogen and oxygen. Provide 9 kcal per gram. Insoluble in
water. Stored as adipose tissue. Ex: butter, margarine, oils
can provide energy if needed, but they are not a primary fuel
source, proteins support tissue growth, repair and maintenance.
Composed of carbon, hydrogen, oxygen and nitrogen. 4kcal of energy
: are vitamins a and c, thiamin, calcium and magnesium. Need
less of them.
: assist with the regulation of body processes.
-Fat-soluble: stored in human body (A,D,E,K) are soluble in lipid
molecules and can be stored in our tissues; these include vitamins a, d, e
and k. they do not provide energy!
-Water-soluble: not stored in human body, are soluble in water, and
we can excrete excess amounts in our urine. These include vitamin c and
the b-vitamins (thiamin, riboflavin, niacin, vitamin b6, b12, pantothenic
acid, biotin and folate)
inorganic substances that are not changed by digestion or
