Amino acids- the building blocks in proteins
Essential Amino Acids- Must come from food.
Ex- meat, fish, milk, eggs
These contain complete proteins
Complete Proteins- Provide all the amino
acids your body needs. Ex- meat, fish, milk,
eggs
Incomplete Proteins- Do not contain all the
necessary amino acids. Ex- Most food from

Carbohydrates- Provide energy for your
body.
Simple Carbohydrates- Natural sugars,
such as those found in fruit and milk
products. They enter the blood rapidly

Excellent source of FIBER
CARBOHYDRATES
Fiber- The part of grains and plant food
that your body cannot digest
 Helps move food and waste products
through your body during digestion and
elimination.
 NOT a nutrient because it is NOT digested
and does NOT provide energy or materials
for growth
 Ex- oat bran, wheat bran, beans, peas,
nuts, apples, grapes, green vegetables

FIBER
 Fats-
provide energy and help
the body use certain vitamins
more effectively.
 Saturated fats- found in many
animal foods such as meat and

grains or cereals
Too much cholesterol in your body can
increase your risk of HEART DISEASE
Unsaturated fats- found in plant products
and fish.
Do NOT present the same health risks as
saturated fats.
CHOLESTEROL,
UNSATURATED FATS
 Water-

 Cushions joints

VITAMINS
Fat soluble vitamins- These can be stored
in the body
 Ex- A, D, E, and k
 Water soluble vitamins- These CANNOT be
stored in the body in large amounts.


Your body needs 13 different essential
vitamins.
