Chapter Two Flashcards
What does an individual’s nutritional needs depend on? (3)
Age, gender, and genetic makeup.
What are the two approaches to making a nutrition recommendation?
- Nutrient Based approach
2. Food Based approach (where a dietary pattern is used)
What is a dietary pattern?
A description of a way of eating that includes the types and amounts of recommended foods and food groups, rather than individual nutrients. (ex. how many fruits and vegetables should be eaten)
What are DRIs?
Dietary Recommended Intakes, a set of reference values for the intake of energy, nutrients, and food components that can be used for planning and assessing the diets of healthy people in the United States and Canada. Designed to promote health and prevent nutrient deficiencies.
True or False: Canada’s Food Guide is nutrient based.
False, it is a food based dietary pattern that has been a central tool in the promotion of healthy and nutritious eating.
How often should eggs be eaten?
At least 3 or 4 eggs should be eaten weekly.
True or false: The DRIs are for every one; sick, ill, or healthy.
False. DRIs are designed to be used for planning and assessing the diets of healthy people.
What are Life-Stage Groups?
Groups that DRIs are separated into that account for the different needs of people based on stages of growth and development, pregnancy, and lactation. They account for the physiological differences between infants, children, adolescents, adults, and seniors. Male and female differences are also taken into account.
What are the four different DRI reference values?
- Estimated Average Requirement (EAR)
- Recommended Dietary Allowance (RDA)
- Adequate Intake (AI)
- Tolerable Upper Intake Level (UL)
What are RDAs?
Recommended dietary allowance, intakes that are sufficient to meet the nutrient needs of almost all the healthy people in a specific life stage and gender group.
What are AIs?
Adequate intakes, intakes that should be used as a goal when no RDA exists. These values are an approximation of the average nutrient intake that appears to sustain a desired indicator of health.
What are ULs?
Tolerable upper intake levels, maximum daily intakes that are unlikely to pose a risk of adverse health effects to almost all individuals in the specified life-stage and gender group.
What are EARs?
Estimated average requirements, intakes that meet the estimated nutrient needs of 50% of individuals in a gender and life-stage group.
Define Criterion of Adequacy
A functional indicator, such as the level of a nutrient in the blood, that can be measured to determine the biological effect of a level of nutrient intake.
Define Requirement Distribution
A plot of the nutrient requirements for a group of individuals in the same life stage. Typically has a bell-curve shape.
