Reading and understanding nutrition labels is complicated, especially with all the acronyms tossed about in nutrition science. Here's a quiz to check how up-to-date you are in your knowledge of nutrition labels.

1. RDA (recommended dietary allowance) is the average daily intake of vitamins, minerals and protein that will meet the nutrient requirements of nearly all healthy people. True or false?

2. The RDA also includes the goal of preventing chronic diseases such as osteoporosis and heart disease. True or false?

3. AI (adequate intake) means if you eat this amount daily, it's enough for good health. True or false?

4. UL (tolerable upper intake level) means you should consume a minimum of this amount daily. True or false?

5. If there is no UL for a nutrient, you should consume as much as you can. True or false?

6. All DRI (dietary reference intake) or known nutrition information is listed on food labels. True or false?

7. RE (retinol equivalent) is the unit of measure used for vitamin A. True or false?

Answers to your right.

Answers: 1) True; 2) True; 3) False. AI means there is not enough scientific evidence to determine an RDA. AI is an assumption that this amount will promote health. 4) False. UL is the highest amount of a nutrient that can be safely eaten on a continual basis without causing adverse effects for most healthy people. 5) False. It may mean that the UL is not known or that any amount is safe. 6) False. Currently, only RDAs are listed, but that may change. 7) True.
