What is Nutrition?

• Definition-Nutrition is the process of a living
  being's ability to eat foods and use the
  components of those foods to fuel growth and
  development.
• Nutrition is important to understand so that we
  can make healthy food choices.

Nutrition

• We need good nutrition to be healthy. If we eat
  poorly, we are more likely to be sick and
  unhealthy.

4
What are in the foods we eat?

• Calories- are the units of heat that measure the
  energy used by the body and the energy that foods
  supply to the body.
• We need a minimum of 2000 calories to stay
  healthy.
• Nutrients- are the substances in your food that
  your body needs to grow, to repair itself, and to
  supply you with energy.

5
The 6 Essential Nutrients

• There are 6 classes of nutrients that we must
  understand!!!
• Without them we CANNOT SURVIVE!
• Carbohydrates
• Fats
• Proteins
• Vitamins
• Minerals
• Water

6
Carbohydrates

• Are the starches and sugars present in food.
• Are the bodys preferred source of energy.
• We should get about 50-60 of our calories every
  day from Carbohydrates.
• There are 4 calories per gram of Carbohydrates.

7
Fats (Lipids)

• A fatty substance that does not dissolve in
  water.
• Fats provide more than twice the energy of
  carbohydrates or proteins.
• They have 9 calories per gram

8
Fats (cont.)

• 20-30 of our calories should come from fats.
• Fats are also used for insulation of the body,
  protection of the internal organs, and they help
  transport important vitamins through the blood
  stream.
• We want to stay away from saturated fats and
  trans fats.

9
Protein

• One of the body's nutrients that builds and
  repairs tissues. Protein is made of amino acids
  and can be categorized as complete and
  incomplete.

10
Protein Cont.

• Complete proteins contain all essential amino
  acids, examples are beef, chicken, fish, and
  eggs.
• Incomplete proteins include vegetables, fruits,
  grains, seeds, and nuts.
• We should get about 10-20 of our calories from
  proteins.

Vitamins

• Vitamins are nutrients you must get from food
  because your body can't make them from scratch.
  They allow chemical reactions to take place
  inside your body.
• Only 13 compounds are considered vitamins.

13
Vitamins Cont.

• Vitamins A, D, E, and K, the four fat-soluble
  vitamins, tend to accumulate in the body.
• Vitamin C and the eight B vitamins dissolve in
  water, so excess amounts are excreted.
• Can you name some vitamins?

14
Minerals

• Are substances the body cannot manufacture but
  are needed for forming healthy bones and teeth
  and for regulating many vital body processes.
• They help support the many complex chemical
  reactions inside our bodies. We need them on a
  cellular level.
• What are some of the minerals our bodies need?

15
Water

• Our bodies are estimated to be about 60 to 70
  water. Blood is mostly water, and our muscles,
  lungs, and brain all contain a lot of water. We
  need to drink water because water is needed to
  regulate body temperature and to provide the
  means for nutrients to travel to all our organs.
  Water also transports oxygen to our cells,
  removes waste, and protects our joints and
  organs.

16
Water Cont.

• How much water should we drink a day?
• Take half your body weight and drink that many
  ounces of water a day.
• Example 120 pound person should drink 60 ounces
  of water everyday

  healthy they are for us.
