 Glucose: Blood
 Fructose: Fruit
 Galactose: Milk
 Sucroce: Table sugar
Starches
◦ Complex Carbohydrates
Fiber

Important energy source
◦ Lipid family which includes fats and oils
Hydrogenation: adds hydrogen atoms to
unsaturated fatty acids (liquid) turning them into
more saturated solid fats
◦ Crisco and margarine sticks
Cholesterol: fatlike substance found in every cell
in the body
◦ Important… found in skin tissue, produces hormones
◦ Two types: Dietary and Blood

Provide energy, encourage growth and
tissue repair
Made up of small units called amino acids
◦ 20 important to the human body: 9 your body
can’t make and 11 it can
Complete protein: animal foods and soy
Incomplete proteins: plant foods
◦ Must pair 2 foods together: beans and rice

Are complex organic substances
◦ Normal growth, maintenance, and
reproduction
◦ Your body cannot produce all vitamins you
can get those by eating a nutritious diet.
Fat-soluble vitamins: carried in fatty parts of
foods and dissolve in fats (body stores them in
fat... build up can be dangerous)
Water-soluble vitamins: dissolve in water (body
does not store them)

pyridoxal, pyridoxamine)
◦ Folacin (folic acid)
◦ Vitamin B12
Vitamin C

In addition to vitamins your body also needs 15
minerals that help regulate cell function and
provide structure for cells. Major minerals, in
terms of amount present, include calcium,
phosphorus, and magnesium. In addition, your
body needs smaller amounts of chromium,
copper, fluoride, iodine, iron, manganese,
molybdenum, selenium, zinc, chloride,
potassium and sodium.
Amounts needed for most of these minerals is
quite small and excessive amounts can be toxic
to your body.

13. WWaatteerr
Water is your body's most important nutrient, is
involved in every bodily function, and makes up 70- 75%
of your total body weight. Water helps you to maintain
body temperature, metabolize body fat, aids in
digestion, lubricates and cushions organs, transports
nutrients, and flushes toxins from your body.
Everyone should drink at least 64 ounces per day, and if
you exercise or are overweight, even more. Your
blood is approximately 90% water and is responsible
for transporting nutrients and energy to muscles and
for taking waste from tissues.
