One important reason you eat is to take in calories.

heart disease, stroke, cancers, and osteoporosis (bones become fragile and more likely to break).

5. To survive, the human body needs the nutrients found in food.
Nutrients are classified into 6 groups: carbohydrates, proteins, fats, vitamins, minerals, and water.

6. Carbohydrates -
The starches and sugars present in foods. The body’s preferred source of energy (providing 4 calories per gram).
Your body uses energy from carbohydrates to perform EVERY task.
Carbohydrates are
classified as either simple
or complex.

7. Simple Carbohydrates-
Sugars (found in fruit, milk, and table sugar)

8. Complex Carbohydrates -
- Starches (found in whole grains, seeds, nuts, beans, potatoes).

9. The body must break down complex carbohydrates into simple carbohydrates before it can use them for energy.

10. HUH?!?!? Your body converts ALL carbohydrates into glucose.
Glucose - a simple sugar that is your body’s main source of energy.
If your body does not use the glucose right away it is stored in the liver and muscles as a substance called glycogen.

-List 5 healthy foods served in the cafeteria. - List 5 unhealthy foods served in the cafeteria.

12. body fat What does your body do when it needs more energy??
- It converts the glycogen back to glucose.
Is it possible to take in more carbohydrates than your body can use right away or store as glycogen???
-YES!! When this happens your body converts and stores the excess carbohydrates as….
body fat

13. Fiber -
- An indigestible complex carbohydrate that is found in the tough, stringy parts of vegetables, fruits, and whole grains.
Fiber can’t be digested and used
as energy but it helps move
waste through the digestive
system and helps prevent
intestinal problems such as
constipation.

14. Proteins -
- nutrients that help build and maintain body cells and tissues.

15. Proteins continued…
During the major growth periods (infancy, childhood, adolescence, and pregnancy) the body uses the protein to build new cells and tissues.
Throughout your life, the body replaces damaged and worn out cells by making new ones from proteins.
Proteins also supply the body with energy, although it is not the body’s main source of energy.

16. Good sources of proteins are animal products:
Proteins continued….
Good sources of proteins are animal products:
- fish,
- meat
- poultry

Animal fats, such as lard,

Chicken & Fish are LOWER in saturated fat.
A high intake of saturated fat can
increase the risk of heart disease.

22. The role of FATS:
Fats transport vitamins in your blood to help with growth and healthy skin.
Fats also add flavor and texture to foods, and because they take longer to digest, they satisfy hunger longer than other nutrients.
Foods high in fats tend to be
high in calories.
Consuming too much fat
increases your risk of weight
gain and obesity.

23. Cholesterol A waxy lipidlike substance that circulates in the blood.
What the body makes on its own is used to produce cell membranes, nerve tissue, Vitamin D, produce hormones, and bile (which helps digest fats).

24. Cholesterol Continued….
Excess cholesterol is deposited in the arteries (which includes HEART ARTERIES!!!)
Arteries can become clogged which can increase the risk of heart disease.
Question:
Is high cholesterol something
that is hereditary?
YES!!

25. Cholesterol continued…
You can’t control age and heredity but you can control what you eat.
