QUESTIONS WITH VERIFIED ANSWERS
Dietary Reference Intakes (DRIs) - Answers - A set of reference values utilized to
assess and plan the nutrient intake levels of typically healthy individuals.
Recommended Dietary Allowance (RDA) - Answers - *THE GOLD STANDARD*
Avg. daily levels of sufficient intake to meet nutritional requirements of 97-98% of
healthy people.
Adequate Intake (AI) - Answers - Established only when RDA is unavailable, sets
nutritional adequacy.
Estimate Average Requirements (EAR) - Answers - Nutrient amount that meets 50% of
a healthy individual's needs.
Tolerable Upper Intake Level (UL) - Answers - The maximum daily amount of a nutrient
that is unlikely to result in adverse health effects.
Exceeding 100% of RDA is good except for __________, __________ ________, and
______________. - Answers - sodium, saturated fat, and cholesterol.
What are the six classes of nutrients? - Answers - Carbohydrates, proteins, lipids,
vitamins, minerals, and water.
What is the difference between essential and nonessential nutrients? - Answers -
Essential nutrients must be obtained from the diet while nonessential nutrients can be
synthesized by the body.
What are phytochemicals? - Answers - Phytochemicals are biologically active
compounds found in plants. Found in high quantities in produce that is dark or bright
colored.
What are valid sources of nutrition information? - Answers - Peer-reviewed journals,
registered dietitians, and reputable health organizations.
What are signs of misinformation in nutrition? - Answers - Exaggerated claims, lack of
scientific evidence, and reliance on testimonials rather than research.
How do federal guidelines help prevent chronic diseases? - Answers - They provide
recommendations for healthy eating patterns and lifestyle choices to reduce the risk of
diseases.
, What are the Dietary Reference Intakes (DRI) standards used for? - Answers - They are
used to assess and plan dietary intake for individuals and populations.
How does nutrition research relate to government standards? - Answers - Nutrition
research informs the development and updates of dietary guidelines and public health
policies.
What are the MyPlate food groups? - Answers - Fruits, vegetables, grains, protein, and
dairy.
How are foods categorized based on their level of processing? - Answers - Foods can
be classified as unprocessed, minimally processed, processed, or ultra-processed.
What nutrients are required on Nutrition Facts food labels? - Answers - Calories, total
fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrates, dietary fiber, total
sugars, added sugars, protein, and certain vitamins and minerals.

Which vitamins are oil soluble? - Answers - Vitamin K,A,E, and D
What is the function of phytochemicals? - Answers - They play a role in preventing
chronic conditions such as heart disease and cancer, reduce inflammation, help to heal,
and prevent infections
Define the scientific method? - Answers - 1. Observation
2. Question
3. Hypothesis
4. Prediction
5. Experimentation
6. Conclusion
Epidemiological Research - Answers - Observational study of populations around the
world and the impact of nutrition on health. Does not determine cause-and-effect
relationships.
