List types of nutrition studies |
1.Observational studies/epidemiology studies (2: prospective cohort study, case control study) 2.Human intervention studies (1:clinical studies/trials, single blind, double blind) 3.Depletion-depletion studies 4.Balance studies 5.Animal studies

|
Prospective cohort study |
-Diet and health information is collected and compared over several years, at the end are if any correlations between disease and diet -Epidemiology/observational study, association/correlation not causation Example: Seven countries study and Mediterranean diet (hypothesized that coronary heart disease was a nutritional problem related to fat intake) |
|
|
|
Case-control study |
-Conpares people with a condition with individuals without the condition (with same demographics) -Epidemiology/observational study, correlation not causation |
|
|
|
Clinical trial/study |
-Study of a population where there is an experimental manipulation of some members of the population and observations and measurements to determine effects compared to a control group who did not have the intervention -Single blind vs. Double blind studies |
|
|
|
What are two studies to determine nutrient requirements? |
1.depletion-repletion studies: study that feeds a populations diet without a nutrient to see the effects/signs of deficiency then adds the nutrient back to the diet where health is restored 2.balance studies: study that compares total amount of a nutrient that enters the body with the total amount that leaves the body |

Describe the key findings of the seven countries study by Ancel Keys |
Results showed blood cholesterol levels were strongly correlated with coronary heart disease deaths In Finland where saturated fat intake was high there were higher blood cholesterol levels and higher incidence of heart disease But in Mediterranean countries risk of heart disease was lower 15,000 men studied for ~10 years from 7 countries on different continents From this study came the Mediterranean diet |
