NUTR+MET+DIAG Flashcards
(66 cards)
what are the four functions of nutrition?
-Allow for growth & repair
-Provide energy for body systems
-Improves metabolism (how we utilize our energy)
-Reduce risk of injury & illness
What are the 6 essential nutrients that the human body requires
Carbohydrates
- Lipids
Proteins
Vitamins
Minerals
Water
What does MEET, REDUCE, and CONTRIBUTE mean?
-meet your needs for vitamins, minerals a
other nutrients
• reduce your risk of obesity, type 2
diabetes, heart disease, certain types of
cancer and osteoporosis
-contribute to your overall health and
vitality
What are MACRONUTRIENTS
fats (lipids), carbs and proteins (Amino
Acids) which provide the body with energy.
What category of nutrients are WATER, MINERALS, and VITAMINS
Micronutrients
What do ORGANIC nutrients contain
-Carbon & hydrogen
• Include carbohydrates
fats and proteins and
vitamins
- Came from *once-
living
What do INORGANIC nutrients contain
-Do not contain carbon &
hydrogen
- Include minerals and
water
What are Carbs
Primary fuel source
What are fats/lipids
-Contain less oxygen and water than carbs so gives a higher energy yield/production
-Are an important source of
energy at r and during low
intensity workouts
What are the two categories of FATS
Solid fats = butter, lard, margarine
Liquid Fats= vegetable oils, oils
What is CHOLESTEROL
A form of a lipid which is
produced by the body but can also be
consumed in our diet.
what are the functions of PROTEINS
Support tissue growth, repair and maintenance.
Contain nitrogen as well as C, H2 and 02
The building blocks are amino acids
How many cal/gram does protein provide?
4cal/gram
Is water organic or Inorganic
Inorganic
What are the two types of simple carbs
monosaccharides - single sugars
disaccharides - 2 monosaccharides bound together
describe GLUCOSE
-mild sweet flavor
-known as blood sugar
-essential energy source
-found in every
disaccharide and
polysaccharide
describe FRUCTOSE
-sweetest sugar
-found in fruits and honey
-added to soft drinks, cereals, desserts
describe GALACOSE
-hardly tastes sweet
-rarely found
-naturally occurs as à
single sugar (mono)
-Half of what makes
up “lactose” (added
late)
describe SUCROSE
- is fructose and glucose together
-tastes sweet - found in fruit, vegetables,
-grains
-table sugar is refined
sugarcane and sugar
describe LACTOSE
-glucose and galactose
-main carbohydrate in milk
known as “milk sugar”
what are COMPLEX CARBS made out of?
-polysaccharides
glycogen and starch
built entirely of glucose
-fiber
variety of monosaccharides and other carbohydrate derivatives
describe STARCHES
- stored in plant cells
- Long UNBRANCHED chains of glucose molecules
-body hydrolyzes plant starch to glucose
What is Glycogen?
How we store energy
how does the term “Like Oil and Water” apply to lipids?
water hates fat, fats are scared of water
