What is Dietary Reference Intakes and what are the 5 sets of standards?

(DRIs) - Recommendations from the food and nutrtion board 5 sets of standards: - Estimated Average Requirements (EAR) - Recommended Dietary Allowances (RDA) -Adequate Intakes (AI) -Tolerable Upper Intake Levels (Upper Levels, or Ul) -Estimated Energy Requirements (EER)

-Intended for diet planning -Should aim to meet and RDA's or AI's set -Do not exceed upper level for a nutrient

What are Adequate Intakes (AIs)? — How are they determined/measured?

AIs - daily intake amounts set for nutrients for which there is insufficient research to establish an estimated average requirements (EAR). -Based on observed or experimentally determined estimates of average nutrient intake that maintains a defined nutritional state - Should cover 97 to 98% of individuals

AMDR's - provide a range of intake associated with good health and a reduced risk of chronic diseases Set for intake of: - Carbohydrate -Protein -Fat -Essential fatty acids

How does one keep a good Calorie balance in a Healthy Eating Pattern?

Calorie needs vary depending on person's age, sex, height, weight, and level of physical activity Monitor body weight and adjust calorie intake and expenditure in physical activity over time to achieve and maintain a healthy weight. Children and adolescents encouraged to maintain calorie balance to support normal growth and development without excess weight gain. Overweight or obese children should change eating and physical activity behaviors to maintain or reduce rate so they can reduce body mass index.

What are Estimated Average Requirements (EARs)? How many nutrients are they set for? And how are they measured?

EARs are daily nutrient intake amounts estimated to meet needs of half of the people. -Set for 17 nutrients. -Measures called functional markers, evaluate activity of enzyme in the body or ability of cell or organ to maintain normal physiological function. - If not measurable functional market is available, EAR cannot be set. -Used to evaluate adequacy of diets of GROUPS, not individuals.

What are Estimates Energy Requirements (EERs)? — What's the goal of EER's?

EER's - average daily energy (calorie) need for each life-stage group - Energy from carbohydrates, protein, fat, and alcohol consumed in amounts above need is stored as body fat - Used to promote healthy body weight

Nutrient density is a tool for assessing the nutritional quality of an individual food

How do nutrition facts panels come up with % Daily value?

Nutrition facts panel lists amounts of certain food components and reports them as % Daily value.

What are Recommended Dietary Allowances (RDAs)? —How are they measured?

RDAs- daily nutrient intake amounts sufficient to meet the needs of nearly all individuals (97 to 98%). -Set an amount based on nutrients ability to prevent chronic disease rather than just prevent deficiency. -RDA is higher than average human needs. -If average intake is less than the RDA and person is healthy, one's need for vitamin is probably less than the RDA.

What are Reference Daily Intakes (RDI's) — What are they used for?

RDI's - set for vitamins and most minerals -For people over 4 ,standards tend to be set at the highest RDA value for any life-stage group. -RDI's are used to calculate percent DV on Nutrition Facts panels.

Daily Reference Values (DRV's) standards are set for what three things? What are DRV's based on?

Standards For: -Energy-producing nutrients -Cholesterol -Sodium For energy producing nutrients DRV's are based on daily caloric intake

How do you determine Nutrient Density?

To determine: -Divide the amount of a nutrient in a serving of food by your daily recommended intake (DRI). -Next, divide the calories in a serving of the food by your daily calorie need (EER). -Compare these values: food is nutrient dense if it provides a greater contribution to your nutrient need than you calorie need.

What are Tolerable Upper Intake Levels (Upper Levels, or ULs)? — What's the goal of ULs?

Upper levels or Ul's - maximum daily intake amounts of nutrients that are not likely to cause adverse health effects on 97 to 98% of individuals - Applies to chronic daily use -Set to protect those who are susceptible in the healthy population
