Water soluble vitamins |
|
Definition
Fat soluble: A,D,E,K
Water soluble: C, B
these regulate but are NOT a source of energy |

One bagel with an ounce and a half of cream cheese contains 39 grams of carbohydrate, 10 grams of protein, and 16 grams of fat. Calculate total number of energy
|
|
Definition
39 g carbohydrate x 4 kcal/g = 156 kcal
10 g protein x 4 kcal/g = 40 kcal
16 g fat x 9 kcal/g = 144 kcal
Total= 340 kcal

observational studies
Compares disease rates among population groups and attempts to identify related conditions or behaviors such as diet and smoking habits
Shows correlation but NO cause and effect
ex: correlation of women in populations who consume more soy products have less incidence of breast cancer than women in populations that consume very little soy

Definition
•Provide a way to control many factors in experiments
•May provide preliminary data that can lead to human studies or can be used to study hypotheses that can’t be tested on humans
•Animal study results can’t be directly applied to humans
|
|
|
Term
|
Definition
Small scale epidemiological studies that compare a group that suffers from a condition such as breast cancer with a similar group that doesn’t
Try to identify factors other than the disease that differ between the 2 groups
•Differences could be in dietary factors
•May provide clues about the cause
•Show a correlation but not cause and effect

Definition
- An intervention is used to determine its effect on certain health parameters
- Could be a drug, nutrient supplement, controlled diet, or exercise program
- These studies include an experimental group and a control group
- Experimental group receives the treatment and the control group doesn’t
-participants randomly assigned to groups
- could be double blind study
-some receive placebo
-expensive and time consuming
-shows cause and effect

| Dietary Reference Intake(DRI's) |
|
Definition
•Reference values for nutrient intakes to be used in assessing and planning diets for healthy people
4 elements:
1. Estimated Average Requirement (EAR)
2. Recommended Dietary Allowance (RDA)
3. Adequate Intake (AI): used when EAR and RDA can't be determined
4. Tolerable Upper Intake Level (UL): intake above can be harmful
|

|
Term
Estimated Average Requirement (EAR) and
Recommended Dietary Allowance (RDA)
How are they determined?
|
|
Definition
EAR: Amount that meets the nutrient requirements of 50% of people in a life stage/gender group
-Based on functional indicator of optimal health
RDA:Amount that meets the needs of most people (97%-98%) in a life stage/gender group

Proteins:10-35%
Fats: 20-35%
Carbs: 45-65%
