Exam 1 Flashcards
Dietary Reference Intakes (DRIs)
–General term–Nutrient intake standards for healthy people
Recommended Dietary Allowances (RDAs)
–Levels of essential nutrients–Adequate for most healthy people–Decrease risk of certain chronic diseases
Adequate Intakes (AIs)–
“Tentative” RDAs–Based on less conclusive scientific information
Estimated Average Requirements (EARs)
–Estimated values to meet requirements of half of the healthy individuals in a group–Used to assess adequacy of intakes of population groups
Tolerable Upper Intake Levels (ULs)
–Upper limits of nutrients compatible with health–Limits that should not be exceeded
Monosaccharides:
glucose, fructose, galactose
Disaccharides:
sucrose, maltose, lactose
Complex carbohydrates (i.e., polysaccharides)
–Starches: plant form–Glycogen: animal form–Most types of fiber
Glycemic index:
extent to which carbohydrate-containing foods increase blood glucose levels–High glycemic index foods raise blood glucose levels more
amdr carb
45-65 percent of calories
Carb g/day for m/f
m: 30-38
f: 21-25
high-quality proteins provide all _______
essential amino acids
ex of high quality proteins

amdr protein?
10-35%
Triglyceride structure
–Three fatty acids attached to glycerol
Essential fatty acids
–Linoleic acid: parent of the omega-6 family –Alpha-linolenic acid: parent of the omega-3 family •Most adults do not consume adequate levels of omega-3 fatty acids
saurated fat
no double bond
unsaturated
monounsaturated (one bond) or polyunsaturated (2+ bonds)
Hydrogenation:
adds hydrogen to unsaturated fatty acids•Changes structure of fatty acid from cis structure to trans form
Dietary cholesterol
–Fat-like, clear liquid found in animal products
