Define nutrition
the study of foods, their nutrients and other chemical constituents, and their effects on the body
nutrient
Chem. Substances in foods that nourish the body (Water, carbs, fats, protein, vitamins, and minerals)
essential nutrients / non essential nutrients
nutrients we must get from our food sources / nutrients the body makes on its own or isnt needed
malnutrition
Poor Nutrition
Nutrient Dense Foods
Foods that contain high nutrients compaired to their kCal
Empty Calorie
Foods that contain excess kCal with little nutrients
Organic
Nutrients that contain carbon
DRI
Daily Reference Intakes
-designed for healthy individuals
*most scientific standards
-based on the most current research
-age/gender specific
4 Subcategories:
*RDA
*EAR
*AI
*UL
RDA
Recommended Dietary Allowances
-represent nutrient intake goals for individuals
-derived from EAR (Estimated average requirements)
-covers the needs of 98% of the population
-Built in MARGIN OF SAFETY
*not a minimal requirement, has padding
*indv. needs
RDA's are set near the top end of the range of the pop's est. reqrmnts. to ensure that the nutrient RDA meet the need of most healthy people
*given nutrient is based on enough scientific evidence to expect the the needs of almost all healthy people will be met
EAR
Estimated Average Requirement
-Population wide average nutrient requirements for nutrition reasearch and policy making
-basis upon which RDA's are set
AI
Adequate Intake
-nutrient intake goals for individuals
-set whenever specific data are insufficent to set an EAR
*usually a range of suggested intake
*may be used as a nutritent goal for individuals
-relies heavily on scientific judgement because sufficent evidence is lacking
UL
Upper Limits of Intake
-for potentially toxic nutrients
-intakes above the UL are likely to cause illness from toxicity
DV
Daily Values
-Cho: 58%
-Protein: 12%
-Fat: 30% (Sat fat 10%)
-Simple Sugar: 10%
State the kcal per gm of cho, pro, fat, alcohol.
Cho-4
Pro-4
Fat-9
Alchohol-7
Calculate the kcal in a food based on the gms of cho, pro and fat in that food
ex:how many calories are in 3 gms of fat?
27
Identify groups that are at greatest risk for malnutrition.
-obese
-elderly
-low income
-any time growth is rapid
-pregnant women
Describe how DRI’s/RDA’s are set, and for whom they are designed
They are meant for healthy people and are set by a group of highly qualified scientist who use the results of thousands of research studies to set standards that define the amounts of energy, nutrients and other dietary components that best support health.
Name the groups in ChooseMyPlate, the number of servings recommended from each group, and what constitutes a serving
*Grains= 6 oz.
Serving size=1 slice of bread, 1/2c cooked rice, pasta, cereal
*Veggie= 2.5c
Serving size=1c/ 2c fresh leafy greens
*Fruit= 2c
Serving size=1/2c fresh/1/4c dried

Serving Size 1 cup/ 1.5 oz cheese
*Oil= 6 tsp
Serving size
Identify the components of a nutrition assessment, and what each component indicates
a. Diet History
-primary deficiency
b. Health History
- secondary problems in the body
c. Lab Tests
- declining nutrients stores
d. Physical Exam
- outward signs and symptoms
e. Anthropometric Measurements
- weight: short term

Identify the key surveys that monitor nutrition and health status in the US population
*National Nutrition Survey
*National Health and Neutrino Exam Surveys (NHANES)
*Continuing survey of food intakes by Individuals (CFSII)
*National Health Goals
*Healthy People 2020
National Nutrition Survey
-National nutrition monitoring Program uses survey research to collect data on foods people eat and peoples health status
-data collected is used for nutrition policy food assistance programs and food supply regulation
National Health and Neutrino Exam Surveys (NHANES)
-50,000 people surveyed
-records measure of their health status
Continuing Survey of Food Intakes by Individuals (CSFII)
-Records what people have actually eaten for two days
-compares the foods they have choosen with the recommended food selections
National Health Goals
-Healthy People is a national public health initative under the U.S. Department of health and human services that is published every 10 years
-Identifies the most significant threats to health
-focuses efforts on eliminating these threats
Healthy People 2020
-Redirects our attention from health care to the determinants of health in our social and physical environments
-contains 1200 objectives in 42 topic areas designed to serve as a frame for improving the health of all people in the US.
