Unit 2 - Introduction to Nutrition Flashcards
A diet which provides all of the essential nutrients, fiber, and energy in amounts sufficient to maintain health & body weight.
Adequate Diet
Foods to which nutrients have been added.
Enriched & Fortified Foods
The nutrients the body cannot make for itself (or cannot make fast enough) from other raw materials; nutrients that must be obtained from food to prevent deficiencies
Essential Nutrient
Scientifically, materials, usually of plant or animal origin, that contain essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals, and that are ingested and assimilated by an organism to produce energy, stimulate growth, and maintain life; socially, a more limited number of such materials defined as acceptable by a culture.
Food
Whole or modified foods that contain bioactive food components believed to provide health benefits, such as reduced disease risks, beyond the benefits that their nutrients confer.
Functional Foods
A term w/ no legal definition, but is often used to imply wholesomeness.
Natural Foods
The study of the nutrients in foods and in the body; sometimes also the study of human behaviours related to food.
Nutrition
Components of food that are indispensable to the body’s functioning. They provide energy, serve as building material, help maintain or repair body parts, and support growth.
Nutrients
To be labeled organic, foods must meet product regulations set out by the:
Canadian Food Inspection Agency (CFIA)
Foods subjected to any process, such as milling, alteration of texture, addition of additives, cooking, or others.
Processed Foods
What are the 6 classes of nutrients?
Carbohydrates, Proteins, Fats, Vitamins, Minerals, Water
What are the 6 classes of nutrients?
Carbohydrates, Proteins, Fats, Vitamins, Minerals, Water
What are the 4 types of research studies?
Case Study, Epidemiological Study, Intervention Study, Laboratory Study
The study of an individual
Case Study
“This person eats too little of nutrient X and has illness Y.” Is an example of which type of study?
Case Study
The study of a whole population; can reveal a correlation.
Epidemiological Study
“This county’s food supply contains more nutrient X and these people suffer less illness Y.” Is an example of which type of study?
Epidemiological Study
Study in which researchers actively intervene to alter people’s eating habits
Intervention Study
“Let’s add foods containing nutrient X to some people’s food supply and compare their rates of illness Y with the rates of others who don’t receive the nutrient.” Is an example of which type of study?
Intervention Study
Done in a lab, can pinpoint the mechanisms by which nutrition acts.
Laboratory Study
“Now let’s see if a nutrient X deficiency causes illness Y by inducing a deficiency in these rats”. Is an example of which type of study?
Laboratory Study
“Now let’s see if a nutrient X deficiency causes illness Y by inducing a deficiency in these rats”. Is an example of which type of study?
Laboratory Study
