Cards

Term
Chronic Disease vs. Acute Disease
Definition
A chronic disease progresses slowly or with little change and lasts a long time. By comparison, an acute disease develops quickly, produces sharp symptoms, and runs a short course.
Term
Nutrition
Definition
The science of foods and the nutrients and other substances they contain, and of their actions within the body (including ingestion, digestion, absoprtion, transport, metabolism, and excretion). A broader definition includes the social, economic, cultural, and psychological implications of food and eating
Term
Foods
Definition
Products derived from plants or animals that can be taken into the body to yield energy and nutrients for the maintenance of life and the growth and repair of tissues
Term
Diet
Definition
The food and beverages a person eats/drinks
Term
Essential nutrients
Definition
Nutrients a person must obtain from food becuase the body cannot make them for itself in sufficient quantity to meet physicological needs; also called indispensable nutrients.
Term
Food choices are determined by...
Definition

-Personal Preference

-Habit

-Ethnic heritage/tradition

-Social Interactions

-Availability, convenience, economy

-Positive and negative associations

emotions

-Values

-Body weight and Image

-Nutrition and health benefits

Term
Functional Foods
Definition
Foods that contain physiologically active compounds that provide health benefits beyond their nutrient contributions; sometimes called designer foods or nutraceuticals
Term
Phytochemicals
Definition
Nonnutrient compounds foudn in plant-derived foods that have biological activity in the body
Term
Energy yielding nutrients
Definition

the nutrients that break down to yeild energy in the body:

carbs

fats

proteins

Term
Six Classes of nutrients
Definition

Carbohydrates

Lipids

Proteins

Vitamins

Minerals

Water

Term
Energy
Definition
The capacity to do work. The energy in food is chemical energy. The body can convert this chemical energy to mechanical, electrical, or heat energy.
Term
Nutrients
Definition
Chemical substances obtained from food and used in the body to provide energy, structural materials, and regulating agents to support growth, maintenance, and repair of the body's tissues. Nutrients may also reduce the risks of some diseases
Term
Macronutrients vs micronutrients
Definition
Carbs, fats, and proteins are macronutrients because the body requires them in large amounts. In contrast, vitamins and minerals are micronutrients,  because the body only requires them in small amounts.
Term
Inorganic
Definition
Not containing carbon. Water and minerals are inorganic
Term
Organic
Definition
Cntains carbon carbon or carbon hydrogen bonds. Organix nutrients include carbs, fats, proteins, and vitamins.
Term
Calories
Definition
Units by which energy is measured. Food energy is measured in kilocalories, kcalories, or kcals.
Term
Energy Density (and Relationship between energy density and weight gain/loss)
Definition

Energy density is the measure of energy a food provides relative to the amount of the food (kcal/gram)

 

Foods with high energy density help with weight gain, whereas those low in energy density help with weight loss. (Think, fat has a greater energy density than carbs or proteins)

Term
Metabolism
Definition
The processes by which nutrients are broken down to yield energy or used to make body structures are known as metabolism.
Term
Vitamins
Definition
Vitamins are organix, essential nutrients required in small amounts by the body for health. They do not provide energy but rather facilitate the release of energy from carbs, fats, and proteins and participate in other activities in the body. Almost every action in the body requires vitamin assistance.
Term
Minerals
Definition
Minerals are inorganic elements, some of which are essential nutrients required in small amounts. They are put together in orderly arrays in such structures as the bones and teeth, and are also found in the fluids of the body. They do  not yield energy.
Term
Genome
Definition
Genome is the complete set of genetic material in an orgnanism or cell. The study of genomes is called genomics.
Term
Nutritional Genomics
Definition
The science of how nutrients affect the activities of genes and how genes affect the interactions between diet and disease
Term
Research terms (review?)
Definition
blind experiment, control group, correlation, double blind experiment, experimental group, hypothesis, peer review, placebo, placebo effect, randomization, replication, subjects, theory, validity, variables
Term
DRI's
Definition

EAR (Estimated Average Requirements)

RDA (Recommended Dietary Allowances (RDA)

Adequate Intakes (AI)

Tolerable Upper Intake Levels (UL)

Term
Deficient
Definition
The amount of a nutrient below which almost all health people can be expected, over time, to experience deficiency symptoms
Term
AMDR (Acceptable Macronutrient Distribution Ranges)
Definition
Ranges of intakes for the energy nutrients that provide adequate energy and nutrients and reduce the risk of chornic disease
Term
Adequate Intake (AI)
Definition
The average daily amount of a nutrient that appears sufficient to maintain a specified criterion; a value used as a guide for nutrient intake when an RDA cannot be determined
Term
Tolerable Upper Intake Level (UL)
Definition
The maximum daily amount of a nutrient that appears safe for most healthy people and beyond which there is an increased risk of health effects
Term
Estimated Energy Requirement (EER)
Definition
The average dietary energy intake that maintains energy balance and good health in a person of a given age, gender, weight, height, and level of physical activity
Term
Estimated Average REquirement (EAR)
Definition
The average daily amount of a nutrient that will maintain a specific biochemical or physiological funciton in half the healthy people of a given age and gender group
Term
Recommended Daily Allowance (RDA)
Definition
The average daily amount f a nutrient considered adequate to meet the known nutrient needs of practically all healthy people; a goal for dietary intake by individuals
Term
Registered Dietician (RD) and Dietetic Technician, registered (DTR)
Definition
They are college educated food and nutrition specialists who are qualified to evaluate peoples nutritional health and needs
Term
Malnutrition (under vs over nutrition)
Definition
Any condition caused by excess or deficient food energy or nutrient intke or by an imbalance of nutrients. Undernutrition is a deficiency of energy or nutrients while overnutrition is an excess of energy or nutrients.
Term
Nutrition assessment
Definition
A comprehensive analysis of a persons nutrition status that uses health, socioeconomic, drug, and diet histories; anthropometric measures; physical examinations; and lab tests
Term
Anthropometric measures
Definition
Relating to measurement of the physical characteristics of the body such as height and weight. The assessor compares a persons measurements with standards specific for genderand age or with previous measures on the same individual
Term
Primary vs secondary vs subclinical deficiency
Definition
A primary deficiency is caused by inadequate dietary intake of a nutrient. A secondary deficiency is a nutrient deficiency caused by something other than an inadequate intake such as a disease condition or drug interaction that reduces absorption, accelerates use, hastens excretion, or destroys the nutrient. And suubclinical deficiency is deficiency in the early stages, before outward signs have appeared
Term
Healthy People Initiative
Definition
This is a national public health initiative under the jurisdiction of the US department of health and human services that identifies the most dignificant preventable threats to health and focuses efforts towards eliminating them
Term
Chronic disease
Definition
Disease characterized by a slow progression and long duration. Examples include heart disease, cancer, and diabetes
Term
Risk factor
Definition
A condition or bejavior associated with an elevated frequency of a disease but not proved to be causal. Leading risk factors for chronic diseases include obesity, cigarette smoking, high blood pressure, high blood cholesterol, physical inactivity, and a diet high in saturated fats and low in vegetables, fruits, and whole grains
