What is DRI
|
includes several categories of nutritional measurements based on gender and life stages
|
|
|
Estimated Average Requirement (EAR)
|
The amount of any one nutrient that meets the needs of half the people in any one group
|
|
|
The average daily amount of a nutrient considered adequate to meet the needs of most (about 97-98%) healthy people
|
RDA (Recommended Dietary Allowance)
|
|
|
Adequate Intake (AI)
|
A range of nutrient intake that satisfies standards for at least 75% of the population, used when there is insufficient evidence to determine an RDA
|
|
|
What does UL stand for
|
Tolerable Upper Intake Level
|
|
|
The highest amount of a nutrient you can consume each day without an adverse effect
|
UL --> Tolerable Upper Intake Level
|
|
|
How does age influence DRI
|
The total number requirement goes up with age, however expressed per unit of body weight, children have higher requirements because they are growing
|
|
|
How does gender affect DRI
|
Males typically require about 20% greater dietary allowances as compared to women
|
|
|
Who would have the highest recommended nutrient amounts?
|
Pregnant and lactating women
|
|
|
What are Atwater conversion factors
|
numbers useful in determining the caloric content of fat, protein, carbohydrates, and ethanol
|
|
|
What is the order of energy content from lowest to highest among the 4 groups used in the atwater conversion
|
carbs=protein<ethanol<fat
|
|
|
How many kilograms are in one pound?
|
2.2
|
|
|
Daily Energy Expenditure (DEE) calculation
|
DEE=REE+ physical activity

|
24 x kg BW
|
|
|
1 lb of fat equals how many calories or kcal
|
3,500
|
|
|
What is the calculation for determining BMI

Kwashiorkor
|
A form of malnutrition that occurs when there is not enough protein in the diet
Characterized by edema and fatty liver |
|
|
Marasmus
|
severe calorie malnutrition
characterized by extreme emaciation, weakness, and anemia |
|
|
Negative nitrogen balance
|
dietary nitrogen intake is less than nitrogen excreted
this occurs when you are lacking in essential amino acids |
