nutri prelim Flashcards
is that which nourishes the body.
may also be defined as anything eaten or drunk,
which meets the needs for energy, building, regulation and protection of the body.
Food
the science of foods and the nutrients and other substances they contain, and of their ingestion, digestion,
absorption, transport, metabolism, interaction, storage, and excretion.
Nutrition
are components of food that are needed by the body in adequate amounts in order to grow, reproduce and lead
a normal, healthy life.
Nutrients
the six classes of nutrients
commonly found in spinach and other foods.
Water,
carbohydrates,
fats,
proteins,
vitamins,
and minerals
(Carbohydrates, Fats, Proteins and Vitamins)
Organic Nutrients
The amount of energy that carbohydrates, fats, and proteins release can be measured
in
calories
Minerals yield no energy in the human body, but, like vitamins, they help to regulate the release of energy, among
their many other roles.
Inorganic Nutrient
During metabolism provides energy the body can use [except vitamins]. These energy-yielding nutrients continually
replenish the energy you spend daily.
Organic Nutrients
set of standards that define the amounts of energy, nutrients, other dietary components,
and physical activity that best support health.
Dietary Reference Intakes (DRI)
a set of values reflecting the average daily amounts of nutrients
considered adequate to meet the known nutrient needs of practically all healthy people in a particular life stage and
gender group; a goal for dietary intake by individuals.
Recommended Dietary Allowances (RDA)
a set of values that are used as guides for nutrient intakes when scientific evidence is
insufficient to determine an RDA
Adequate Intakes (AI)
the average daily nutrient intake levels estimated to meet the
requirements of half of the healthy individuals in a given age and gender group;
Estimated Average Requirements (EAR)
- a set of values reflecting the highest average daily nutrient intake levels that
are likely to pose no risk of toxicity to almost all healthy individuals in a particular life stage and gender group.
Tolerable Upper Intake Levels (UL)
Enough energy is needed to sustain a healthy, active life, but
too much energy leads to obesity.
Estimated Energy Requirement (EER)
As noted earlier, the DRI committee considers prevention of
chronic disease as well as nutrient adequacy when establishing recommendations.
Acceptable Macronutrient Distribution Ranges (AMDR)
overconsumption of food energy or nutrients sufficient to cause disease or increased
susceptibility to disease; a form of malnutrition.
Overnutrition:
under consumption of food energy or nutrients severe enough to cause disease or
increased susceptibility to disease; a form of malnutrition.
Undernutrition:
is the characteristic of a diet that provides all the essential nutrients, fiber, and energy necessary to
maintain health and body weight.
Adequacy
is the dietary characteristic of providing foods in proportion to one another and in proportion to the body’s
needs.
Balance
Foods provide the amount of energy needed to maintain a healthy body weight—not
more, not less.
kCalorie (energy) control:
is a measure of the nutrients a food provides relative to the energy it provides. The more nutrients
and the fewer kcalories, the higher the ____________.
Nutrient density
is the provision of enough, but not too much, of a substance.
Moderation
is consumption of a wide selection of foods within and among the major food groups
Variety
describes a lifestyle that includes only the
activities typical of day-to-day life.
Sedentary
describes a lifestyle that includes physical activity
equivalent to walking more than 3 miles per day at a rate of 3
to 4 miles per hour, in addition to the activities typical of day-
to-day life.
Active
provides such information as serving sizes, Daily Values, and nutrient quantities.
The “Nutrition Facts” panel
statements that characterize the quantity of a nutrient in a food.
Nutrient claims
statements that characterize the relationship between a nutrient or other substance in food and a disease
or health-related condition.
Health claims:
statements that describe how a product may affect a structure or function of the body; for
example, “calcium builds strong bones.” Structure-function claims do not require FDA authorization.
Structure-function claims:
The dietitian/nutritionist collects and documents information such as food or nutrition-
related history; biochemical data, medical tests and procedures; anthropometric measurements, nutrition-focused
physical findings and client history.
Nutrition Assessment:
Data collected during the nutrition assessment guides the dietitian/nutritionist in selection of
the appropriate (i.e., naming the specific problem).
Nutrition Diagnosis:
The dietitian/nutritionist then selects the ____ that will be directed to the
root cause (or etiology) of the nutrition problem and aimed at alleviating the signs and symptoms of the diagnosis.
Nutrition Intervention:
The final step of the process is ________________, which the
dietitian/nutritionist uses to determine if the client has achieved, or is making progress toward, the planned goals.
Nutrition Monitoring/Evaluation:
is a systematic approach to collect, classify, and synthesize important and relevant data
needed to identify nutrition-related problems and their causes.
Nutrition Assessment
is a nutrition and dietetics practitioner’s identification and labeling of an existing nutrition
problem(s) that the practitioner is responsible for treating.
Nutrition Diagnosis
This step consists of three components:
monitoring, measuring, and evaluating the changes in nutrition care indicators.
Collection and Use of Nutrition Monitoring and Evaluation Outcome Data:
(single sugars).
Monosaccharides
(double sugars).
Disaccharides
compounds composed of chains of monosaccharide units.
Polysaccharides—
most cells depend on _____ for their fuel to some extent, and the cells of the brain and the rest of the
nervous system depend almost exclusively on _____ for their energy.
glucose
is the sweetest of the sugars.
Fructose
the third single sugar,
Galactose
sugar) is the most familiar of the three disaccharides and is what people mean when they speak
of “sugar.”
Sucrose
is the principal carbohydrate of milk.
Lactose
is the third disaccharide,
Maltose
