 carbohydrates
Sugars and starches that occur in foods,
mainly in plants
 fiber
The part of fruit, vegetables, grains, and beans
that your body cannot digest
 proteins
Nutrients your body uses to build, repair, and
maintain cells and tissues
 saturated
fats
Fats that are solid at room temperature
 unsaturated
fats
Fats that remain liquid at room temperature
 vitamins
Substances that help your body fight infections
and use other nutrients, among other jobs
 minerals
Elements that help form healthy bones and
teeth, and regulate certain body processes
In this lesson, you will learn to
 identify the six major classes of nutrients.
 explain specific ways your body uses nutrients.
Organizing Information
Make a diagram similar to the one on below. Include a box for
each nutrient and foods that are sources of that nutrient.

Six Groups
of Nutrients

Water
Carbohydrates
There are two kinds of carbohydrates: simple and
complex.
carbohydrates Sugars and starches that occur
naturally in foods, mainly in plants
Carbohydrates
All carbohydrates are made of sugar molecules.
Simple carbohydrates
Complex carbohydrates
Molecules remain separate
Molecules form long chains.
Also knows as starches.
Fruits, vegetables, milk, milk
products
Grains, dried beans, and starchy
vegetables such as potatoes
Half to two-thirds of your daily energy should come from carbohydrates.
Fiber
Fiber is a special type of complex carbohydrate
found in raw fruits, vegetables, and whole grains.
fiber The parts of fruit, vegetables, grains, and beans
that your body cannot digest
Eating high-fiber foods can help reduce your risk of
certain types of cancer and heart disease.
Proteins
Proteins are made up of chemical building blocks
called amino acids.
proteins Nutrients your body uses to build, repair,
and maintain cells and tissues
Proteins also play an important role in fighting
disease because parts of your immune system are
made of proteins.
Proteins
Proteins
Complete Proteins
Plant Proteins
Contain all nine of the essential
amino acids
Lack one or more of the nine
essential amino acids
Beef, pork, veal, fish,
poultry, eggs, most dairy products
Nuts peas, and dried beans
Fats
Eating too many foods containing saturated fats
can increase your risk of heart disease.
saturated fats Fats that are solid at room temperature
Fats
Most of the fats in your diet should be unsaturated
fats.
unsaturated fats Fats that remain liquid at room temperature
Fats
Fats
Saturated Fats
Unsaturated Fats
Butter, cheese, fatty meats
Plant foods such as olive oil, nuts
and avocados
Cholesterol
Cholesterol is a fatty substance found in the blood.
LDL (low-density lipoprotein)
HDL (high-density lipoprotein)
Collects on the walls of arteries and
forms plaque
Removes LDL from the arteries
Known as “bad cholesterol”
Known as “good cholesterol”
Eating too much saturated fat can increase the body’s level of cholesterol.
Vitamins and Minerals
Vitamins and minerals are essential to your body’s
health.
vitamins Substances that help your body fight infections and
use other nutrients, among other jobs
minerals Elements that help form healthy bones and teeth, and
regulate certain body processes
Vitamins and Minerals
Vitamins
Water-Soluble
Fat-Soluble
Not stored in the body
Stored in the body
Must be consumed regularly
Stored in the body’s fat until they
are needed.
The best way to get vitamins and minerals is to choose nutritious foods.
Water
Water
Helps digest and absorb food.
Regulates body temperature and blood circulation.
Carries nutrients and oxygen to cells.
Removes toxins and other wastes.
Cushions joints.
Protects tissues and organs from shock and damage.
Water
Dehydration is a lack of water in the body.
You need to replace the water your body loses by
drinking at least eight 8-ounce cups of fluid each
day.
