Me and 4 other teachers went out to eat Indian food because it is what Ms. Tressler wanted.
My grandma grew up in Mexico so my Mom likes to make HOT chili enchiladas.
I do not have time to make a lunch in the mornings so I keep a loaf of bread, peanut butter, and honey in my office.
While I was in college I never ate out. Now I have a career and I eat out way too much!
Occasionally I see a commercial with something I really want on it so the next time I’m out I’ll go out to eat there.

Questions?????
What is the difference between Nutrients and Calories?
If a food has a lot of nutrients does that mean it has a lot of calories too? Why?
6 Nutrients6 NutrientsWhat are the 6 types of nutrients?
–Carbohydrates–Proteins–Fats–Vitamins–Minerals–Water
CarbohydratesCarbohydratesWhat is the role of carbohydrates?
3 types of Carbohydrates
What are they?
Carbohydrates are your main source of ENERGY!
Simple, Complex, and Fiber

usually contain less nutrients.usually contain less nutrients.
Small group of sugarsCarbohydrate is a sugar
ComplexComplex- Complex- StarchesStarches which are long which are long
chains of sugars.chains of sugars.– Examples: grains, pasta, beans, legumes
and root veggies like potatoes.
Simple vs Complex Sugars
Simple– Glucose: the most common kind of simple sugar. Glucose
is the basic source of energy for all living things. Body converts most sugars into glucose.
– Sucrose: commonly known as table sugar, beet sugar, or cane sugar.
– Fructose: known as fruit sugar.
Complex– Maltose: known as malt sugar. Found in grains.– Lactose: commonly known as milk sugar. It is the principal
carbohydrate found in milk.
Difference between Simple and Complex carbohydrates
Simple Complex-Made of 1-2 sugars -Made of 3+-Digests quickly -Longer to digest-Sugars -Starches
Fiber Fiber- a tough complex carbohydrate that the Fiber- a tough complex carbohydrate that the
body cannot digest.body cannot digest.
.What does Fiber do for us?
• Moves waste through your digestive system• Helps you feel full• Prevents certain diseases• May reduce risk of cancer
• Examples: Potatoes, Celery, Apples, broccoli, nuts
10 to 13 grams of fiber per 1,000 calories you consume.10 to 13 grams of fiber per 1,000 calories you consume.
A few questions about Carbs…
- Carly eats captain crunch for breakfast in the morning with milk.She knows she needs to eat fruits and veggies so she adds in a few strawberries. However, by the time she gets to second period she is starving. Why is this?
-What should she eat so she can last until lunch and why?

largest percentage of our body weight.– Our hair, nails, skin, bones, muscles,
tendons and organs are made up mainly of protein.

sources. They contain all 9 essential amino acids
Plant sources do not contain all 9 essential amino acids and are a variety of sources must be eaten to obtain all of them.
Question about Protein…
Kyle has become a vegetarian. His friends tell him he will be missing out on a lot of high protein foods that will supply him with all the essential amino acids which are important for his growth. If you were Kyle’s doctor what would you say to help him?

Questions…
What was the difference between the winning team and the losing team?
Is your diet high in carbohydrates or protein?
When you find you’re out of energy why could that be?
What can you learn from this clip to help your energy levels?
FatIs it bad to eat fat?What does fat do for us?
• Concentrated form of energy• Cushions our organs from shock• Insulates us, keeps our body temperature
regulated.• Absorb and transport the fat soluble vitamins ADE
and K.
Cholesterol is a waxy substance in your blood that can get stuck in your arteries.
Good Cholesterol and Bad
HDL: High Density Lipoproteins– Want to be higher– The good type of cholesterol that
LDL: Low density Lipoproteins– Want to keep lower– The bad type of cholesterol that can build
up in our systems
ClipClip
Understanding Cholesterol A cholesterol molecule is alipid, which is water-insoluble.Examples are…waxes, oils and fats Because it can't dissolve in water or watery substances likeblood, cholesterol can't movearound in the bloodstream on its own. It has to catch a
ride. In order to travel around the body, cholesterol combines
with protein, forming a lipoprotein (lipid + protein). The protein actually coats the cholesterol.
Water InsolubleWater Insoluble
Understanding Cholesterol However, not all lipoproteins are created equal. When the lipoprotein has more protein than cholesterol, it resembles a
Ferrari, gunning through your body without stopping until the cholesterol arrives at your liver, where it's converted into bile acids. These Ferraris are high-density lipoproteins (HDLs), which most of us just call "good" cholesterol.
When the lipoprotein has more cholesterol than protein, however, this makes for a rickety ride. This low-density lipoprotein (LDL), or "bad" cholesterol, sputters down the road, careening off the arteries, running into things and leaving bits all over the place.
While the HDL Ferrari sees a pileup and nimbly speeds around it, the LDL jalopy crashes right into it, adding to the jumble of tangled fenders and tailpipes (or platelets and plaque).

Deficiency vs Toxicity
Deficiency: When you don’t have Deficiency: When you don’t have enough of a substance in your body.enough of a substance in your body.
Toxicity: When you have too much of Toxicity: When you have too much of a substance in your body.a substance in your body.
Roles of Certain Vitamins
A… Helps with night visionD… Helps use CalciumE… Helps repair tissueK… Helps clot blood
B1… Helps body use carbs for energyC… Helps protect against infection
Minerals
Elements found in food that are used by the body.
Your body cannot produce minerals so they must be obtained from food.
If you don’t get enough vitamins or minerals you may develop a deficiency. (A sickness caused by not having enough of a vitamin or mineral.)
Roles of certain Minerals
Calcium… Healthy bones and teethPhosphorus… Produce energyMagnesium… Muscle and Nerve functionsIron… Helps red blood cells carry oxygen
Water
Water is essential for all body functions– Digestion– Transporting nutrients– Storing and releasing heat– Cooling the body through sweating– Lubricating Joints
8 Glasses of water a day!!!!!!!!!!!!!
Good Nutrition
In order to have good nutrition it’s not just about avoiding the bad things, but eating the right things.

Activity Get into a group of 2-4 In your group write a quiz of 15 questions
from chapter 10 and what we talked about today. Write the answers on the back of the quiz. Trade quizzes with all members in your group
and take each others quiz. If you miss any questions mark it wrong and
circle the response on the back. TF, Multiple Choice, short answer, compare or
contrast, fill in the blank.
Scavenger Hunt (Creativity)
With your team of 2-3 you are going to create or find items to be an example of 10 terms or main ideas from the lesson. You can use whatever example you’d like as long as you can support very strongly why that item could represent that term. Split up the items and be prepared to explain each item.
Show me…-List of 10 terms -Picture of 10 examples-Verbally tell me how they relate
