Carbohydrates (carbs) are the bodys
main source of fuel. 45%-65% of the calories we eat
should come from carbs.
Carbs are easily used by the body for
energy. Carbs are broken down in to glucose
(SUGAR!)
All of the tissues and cells in ourbody can use glucose for energy.
Carbs are NEEDED for the brain, thekidneys, the muscles(including theheart) to function properly.
Carbs can be storedin the muscles and
liver and later used for energy. Created by Alyssa Cardinal

Although fats have a bad reputation forcausing weight gain, some fat is actually
necessary for survival.
25%-35% of the calories we eat shouldcome from FATS.
Important for normal growth anddevelopment.
ENERGY(Fat has the most calories which= the most energy!)
Absorbing certain vitamins (like vitaminsA, D, E, K)
Providing cushioning for the organs
Providing taste, texture and holds food
together.Created by Alyssa Cardinal

Lets do the math!There are 3.5 g of
total fat.

cookie?

Example:
Total fat = 5 g
Total carbs = 34 g
Protein = 2 g
How many total calories?
Answer:
5 g fat x 9 = 45 calories
34 g carbs x 4 = 136 calories2 g protein x 4 = 8 calories

TOTAL: 189 calories

What is the digestive system?
A group of organs and body
structures that break down foodusing chewing, churning, squeezingand special chemicals called
enzymes, in order for the body to
absorb nutrients and remove leftover waste.
What organs and body
structures are part of thedigestive system? Teeth & tongue
Esophagus (food pipe) Stomach
Small intestines
Liver
Gall bladder
Large intestines
Anus
What is an ENZYME?
A chemical made in the body that
breaks food down in to smaller
molecules, or building blocks, sothey can be absorbed by the body.
What is the end product of the
digestive system?
POO!

Lingual lipase & amylase are special chemicals (enzymes)
that break down fats and carbs in the mouth.
Protease, pepsin, and stomach acid (hydrochloric acid)
break down proteins and stomach acid and also kill
bacteria in the food we eat.
Pancreatic lipase and bile are released in the small
intestine to break down fats.
Bile is a chemical produced in the liver that is stored in thegall bladder. When we eat, the gall bladder is signaled to
release bile in to the small intestine to break down fat.

In the small intestine, villi and microvilli (little
fingers) absorb macronutrients (building
blocks) and take them to the bloodstream.
The small intestines are the place where most
of the nutrients our body needs are absorbed.
FUN FACT:By adulthood, the small intestine is about
TWENTY FEET LONG!

The large intestine is the next stop.
The large intestine absorbs water, salt and
potassium from the waste, and puts it back in to
the body. The longer the waste stays in the large intestine,
the more water is absorbed.
FUN FACT:The large intestine is about FIVE FEET LONG.
Large + Small = TWENTY FIVE FEET!
Thats taller than a 2 story house!
QUESTIONS:
What do you think happens to our stool
when it stays in the large intestine for a
short amount of time?
What do you think happens to our stool
when it stays in the large intestine for a
long amount of time?
What happens to our stool when we dont
drink enough water?

After all of the nutrients, water, salt and potassium have been
removed, we are left with: 75% water
25% solid
Of the solid remains:
30% dead bacteria
30% food that cant be broken down, AKA fiber(mostly from plants thatcant be broken down by the body)
For example: Corn, peanuts, peas, carrots, cereals, and beans contain fiber thatcannot be broken down by the body.
10-20% fats
10-20% some minerals
2-3% protein
And small bits of cells from the digestive tract, white blood cells,
and bile pigments.
Fun Fact: Fiber is important for our digestive tract because
it helps food move along the intestines. Created by Alyssa Cardinal

When red blood cells are broken down, a chemical is created
called bilirubin. This is a yellowish-brownish substance that is
removed from the body through our waste. When bilirubin
meets iron, the end result is.. BROWN!!

Cholesterol: A special kind of sticky fat found in
Foods high in saturated fats and oils (butter, fatty meats, lard,
2% and whole milk, fast foods and greasy foods.
Atherosclerosis: The buildup of FAT and CHOLESTEROL on the inside
of the arteries that forms hard structures called PLAQUES!
When we eat diets high in cholesterol as children and adolescents, the
chance of getting atherosclerosis later in life is increased!
Lets take a second to think
What do you think happens to our blood pressure when we form plaques?
How does this affect our heart?

Coronary artery disease:
When atherosclerosis narrows the arteries
close to your heart, this can lead to coronary
artery disease. This can cause chest pain andheart attacks.
Congestive heart failure:
When your heart has to pump super hard to
get blood past plaques, the heart musclesbecome bigger. This is one muscle we DONTwant to get bigger! Because the muscles are
so big, the heart cant fill up with enoughblood. It also becomes hard for the heart to
squeeze blood to the rest of the body, which
can make the heart very tired! Strokes:
When pieces of hard plaques break off, they
can travel to the brain and block blood flow,causing a stroke.
