Dietary reference intakes (DRI)
A set of five lists of values for measuring the nutrient intakes of healthy people in the U.S. and Canada
Daily Values
Nutrient standards used on food labels and on grocery store and restaurant signs
What are the five sets of values in the DRI?
Recommended Dietary Allowances (RDA), Adequate Intakes (AI), Tolerable Upper Level Intakes (UL), Estimated Average Requirements (EAR), Acceptable Macronutrient Distribution Ranges (AMDR)
Which is more reliable, RDA or AI?
RDA, because AI is based on scientific evidence, but also on some educated guesswork. RDA is derived from solid experimental evidence and reliable observations. When the DRI committee find insufficient evidence to generate an RDA, they establish an AI value instead.
What are the calorie percentage ranges for carbohydrates, fat, and protein?
45-65% carbs
20-35% fat
10-35% protein
Balance study
Laboratory study and which a subject is fed a controlled diet and intake and excretion of a nutrient are measured
Estimated energy requirement (EER)
The average dietary energy intake predicted to maintain energy balance in a healthy adult of a certain age, gender, weight, height, and level of physical activity consistent with good health
Can Daily Values serve as nutrient intake goals for individuals?
No. DV reflects the highest level of nutrient need among all population groups, from children of age 4 years through aging adults.
The DRI values set nutrient intake goals, and the Dietary Guidelines for Americans offer…
Food based strategies for achieving them
What are the shortfall nutrients?
Vitamin A,C,D,E
Folate, calcium, iron, magnesium, fiber, potassium
What are the overconsumed nutrients?
Saturated fat and sodium
Adults should engage in at least how many hours of physical activity each week?
2 1/2 hours
Food group plan
A diet planning tool that sort foods into groups based on their nutrient content and then specifies that people should eat certain minimum numbers of servings of foods from each group
The USDA employs a food group plan know as the…
USDA Eating Patterns
Solid fats
Fats that are high in saturated fatty acids and usually solid at room temperature
Empty calories
Calories provided by added sugars and solid fats with few or no other nutrients
What are some examples of solid fats?
Naturally occurring fats such as milk fat and meat fat.
Added fats, such as butter, cream cheese, hard margarine, lard, sour cream, and shortening
Examples of added sugars
All caloric sweeteners, such as brown sugar, candy, honey, jelly, molasses, soft drinks, sugar, syrup
The Food Lists for Diabetes and Weight management helps people manage their calorie intake. Can only diabetics use this?
No. It can be used for anyone concerned about calories
The Food Lists for Diabetes and Weight Management emphasize which 2 characteristics of foods?
Portion sizes and calorie amounts
The way the Food Lists for Diabetes and Weight Management assigns foods to groups is different from the USDA eating patterns? How is it different?
USDA Eating Patterns sorts foods by their vitamin and mineral contents. The Diabetes sorts them based on their carbohydrate, fat, protein, and calorie contents
Nutrition facts
On a food label, the panel of nutrition information required to appear on almost every packaged food
The Nutrition Education and Labeling Act of 1990 has requirements for every packaged food. What must every packaged food state?
1) The common or usual name of the product
2) The name and address of the manufacturer, packer, or distributor
3) The net contents in terms of weight, measure, or count
4) The nutrient contents of the product
5) The ingredients in descending order of predominance by weight and in ordinary language
6) essential warnings, such as alerts about ingredients that often cause allergic reactions or other problems
What information is on a Nutrition Facts panel?
Servings per container Calories/calories from fat Nutrient amounts and percentages of daily values - Total fat - Cholesterol - sodium - total carbohydrate - protein
