NUTRITION
The importance of food.
CARBOHYDRATES
Digestion Time
 Glucose to Fat
 40-65% of our energy
intake.
imgres.webloc
 Unnecessary due to proteins.
 Are found in sugar, bread, pastas, potatoes, rice,
and beans.

PROTEINS
Both animals and plants.
 Essential
 Amino acids (muscles) we cannot make ourselves.
 Extra becomes glucose (fat).
 Take awhile to digest.
 Longer lasting source of energy.


Broccoli has more protein than steak. WHAT!?
FATS/LIPIDS
Necessary for human survival.
 Efficient energy
 Skin and bile use (Myelin sheath)
 Excess energy stored as fat around our middle.
 Less than 10% of our diet should be fat.
 Fat takes a longer time to digest than both
proteins and carbohydrates.

VITAMINS AND MINERALS
(AKA FRUITS/VEGETABLES)
Cannot be made by our own bodies.
 Cannot be stored.
 Need 15 minerals to keep cells going.
 The vitamins most needed are:


Vitamin C (supports immune system)
Vitamin D (makes us feel happy, made from the sun)
Folic Acid
Vitamin B (can increase energy)
Vitamin A (okay, but toxic in high doses)
WATER
No storing unless water deprived.
 The human body consists of 75% water (or 42
Liters).
 If we lose even 3 Liters of water we can become
dehydrated.
 We need to get 8 (8oz cups) a day.

THE TRUTH ABOUT ELECTROLYTES AND
ANTIOXIDANTS
Na, Ca, Mg, Cl, and K (Why and when you need
these.) You conduct electricity?!
 Oxidation? (Why Oxygen is bad for you.)

FIBER
Fiber slows down digestion.
 Is found in beans, whole grain cereals and
breads, vegetables, fruits and nuts.
 Recommended value is 20-35 grams of dietary
fiber a day.

WHAT TO EAT?
Eating a variety of foods at every meal will allow
you to get energy right away, but still feel full
longer.

Ex. Bran muffin (full of fiber), with orange juice (lots
of sugars/carbohydrates)
Orange juice will digest instantly and give you energy short
term.
 Brain muffin will take longer to digest (due to fiber) and
will give you energy later in the morning.

ASSIGNMENT:


Raid the pantry tonight and look at 3 items.
Write down the amount of protein, carbs,
calories, fiber etc.
What will each of these become in the body?
(Consider most food will become multiple things,
so name a few.)
Are these good or bad foods and why? (On
average)
