Terms in this set (105)
- calories are the unit
Where is the "energy" - carbs, proteins, fats all provide energy
in our food? - energy is in the covalent bonds, by breaking
the bonds we get energy
What is a nutrient? a substance that provides nourishment that is
essential for life
How many nutrient 6
classes are there?
What is the role of energy, structure, regulation
nutrients?
- foods
Sources of nutrients - fortified foods
- supplements
Nutrient density = nutrients : calories
What are fortified the addition of extra nutrients to food products
foods? - can be federally mandated or voluntary

a product sold to supplement the diet;
Dietary Supplement may include vitamins, minerals, amino
acids, etc
- not regulated by the FDA
- carbohydrates
- protein
- lipids (fats)
- water
What are the 6 nutrient
- vitamins
classes?
- minerals
- ALL essential our body can't make the nutrient
or it can't make enough of it alone
- energy : the fuel our cells used to do work
Function of Nutrients - structure : muscles, bones, water, tendons, etc
- regulation : body temp, blood pressure,
transport, hormones, etc
- 6% minerals, carbohydrates, vitamins, other
- 16% lipid
What is the average - 16% protein
man?

molecule organic? molecules do not contain carbon
- energy yielding: if we break bonds to get ATP
Energy yielding vs (energy) out of the molecules
non-energy yielding - non-energy yielding: can be used for all
sorts of things but we don't break down
bonds to get ATP
What is a calorie? - a unit describing the amount of energy in food
- measured by the energy it takes to raise 1
kilogram of water 1 degree celsius
- macro nutrients
Carbs - organic (has covalent bonds)
- energy = 4 calories per gram
- macro nutrient
Protein - organic
- energy = 4 calories per gram
- macro nutrient
- every cell in our body is made up of fats
Fats (lipids) - organic (has a very long carbon chain)
- energy = 9 calories per gram
- macro nutrient
Water - inorganic (no carbon)
- energy = non-energy yielding; no bonds to
break; no ATP to gain
