DRI Quiz
Why and when were the RDAs, later called the DRIs, instituted and developed?
- During world war 2, when the army wanted to know how much nutrients soldiers needed
Why do we need Dietary Reference Intakes?
- To have standards so we know how good the diet someone or a population is eating
On the 3 main DRIs, Adequate Intake (AI) is the least strong DRI because
- It does not require nutrient balance studies. It is the average amount of a nutrient in the
food supply of a healthy population
The Estimated Average Requirement (EAR) is a fairly good DRI because
- Balance studies were done in humans and a Mean value for the requirement for the
population was obtained
The Recommended Daily Allowance (RDA) is the strongest DRI because
- Scientists agreed with the final value and have strong confidence in it
- Balance studies were done in human
- Many balance studies were done by different research groups
- Statistical analysis was performed to increase the mean value by 2 Standard Deviations
The Upper Limit (UL) DRI for a nutrient is:
- The highest amount of a nutrient that one can consume on a regular basis without risk of
toxicity
Energy Quiz
Why is it important to discuss energy in a nutrition class?
- Humans store large amounts of energy in adipose cells (fat).
- Humans need energy to think.
- Humans have a heart that requires energy to pump 24 hours a day.
- Humans need to stay warm in wintertime- this requires energy.
When traced back to the original source - the following energy sources are "originally" from the
sun.
- The energy stored in plants as starch
Fire, the internal combustion engine, and metabolism in humans have the following in common.
- They all require a fuel to provide energy
- They all produce CO2
- They all require oxygen
