wrong answerS

• FOOD DIARY can help you understand your eating habits and patterns, and help you identify the foods — good and not-so-good — you eat on a regular basis.
• A 24-hour diet recall is a dietary assessment tool that consists of a structured interview in which participants are asked to recall all food and drink they have consumed in the previous 24 hours
• Usual dietary intake refers to the long-run average or habitual daily intake of a nutrient or food

2) A) a high sensitivity rate.

Sensitivity measures the proportion of positives that are correctly identified (e.g., the percentage of sick people who are correctly identified as having some illness).

WRONG ANSWERS

• Specificity measures the proportion of negatives that are correctly identified (e.g., the percentage of healthy people who are correctly identified as not having some illness)
• a high negative rate IS SAME AS specificity.
