1. Can Good Nutrition Taste Good?

2. Nutrition
Nutrition is the sum total of the processes involved in the taking in and the utilization of food substances by which growth, repair and maintenance of the body are accomplished…
Carbohydrates
Fiber
Fats
Protein
Vitamins
Minerals
Water
All seven must be consumed from the food we eat.

3. Nutrients
Starch – many glucose molecules bonded together; this is a tiny starch molecule
Carbohydrates – sugars and starches – provide needed energy for daily activities; excess carbohydrates will be used to make fats
One glucose molecule – most common sugar in your body

4. Nutrients
Fiber – is actually a carbohydrate – cellulose – that makes up plant cell walls; surprise – we are not cows with special bacteria or termites with special bacteria  WE cannot digest this; but it helps us to be regular; it provides needed bulk to our food.
Similar to starch it is made of glucose molecules, but the bonds between these glucose is not able to be broken by our digestive enzymes.

5. Fats
Animal fats – lard, fat on steak or chicken
Fat – highest energy storing molecules; excess is stored in fat cells; excess fat should be avoided, but every new body cell that is made needs a lot of fat molecules to make it; animal fats can make deposits in arteries
Plant oils – liquid at room temp

6. Nutrients
Protein – very large molecules that are made of amino acids; all of our cells have them and need them; but our muscles need a whole lot of them. Eating meat, beans, peas and other seeds are great sources of proteins.
This is a very small portion of a protein. Compared to the other nutrients, this is huge!

7. Astronaut Food Cannot depend on refrigeration
If your family goes camping or on a picnic, there are certain foods you usually take because it makes sense on that kind of a trip. Your folks do not take a pot roast to cook on a grill. Have you ever thought about what an astronaut’s food would be?
Cannot depend on refrigeration
Must be able to last for months
Cannot require cooking
Must provide the astronaut with all of the needed nutrients
Must take up a very small amount of space
Must not create a great deal of trash
To some degree – it must taste good

8. Ummm, ummm Good!
Astronaut’s diet has to have low iron. Iron is important for our Red blood cells, but in space astronauts have fewer red blood cells and the excess iron would make them sick.

10. Percentage Daily Values
Middle School Students
Calorie Intake by the USDA
Boys –
9 – 13 
14 – 18  2000 – 3200
Girls –
9 – 13  1400 – 2200
14 – 18  1800 – 2400
Lower values for less active individuals.

11. Regular vs. Baked Potato Chips
Why do you think the fat and carbohydrate values are different on these chips? Which do you like?

12. For your food item!
In your interactive notebook write Food Portion Lab
Next, write the food you will measure.
Look at the food label
Find the mass of one serving
Use the scale – mass the cup given to you
Add that mass to the mass of one serving and add enough food to balance the scale at that number.
Answer the questions:
Were you surprised that this was one serving?
If you eat more than one serving of this, how many calories would it be?

13. Homework!!!!
Bring a food label to school on Monday!
If necessary, you can bring it in as a picture, but a can label or box label is perfect!
