◉ 2. What is an essential nutrient? Explain why alcohol is not
considered a nutrient.
Answer: Alcohol yields energy (7kcal/g) when metabolized, but
alcohol is not considered a nutrient because it does not support the
growth, maintenance, and repair of the body.
◉ 3. Given a specific food, calculate the energy contribution
(kcalories) from protein,
fat and carbohydrate.
Answer: Protein(4Kcal/g)
Carbohydrate(4Kcal/g)
Fat(9Kcal/g)
◉ 4. What credentials identify a "nutrition expert"?
Answer: RD (Registered Dietitian)
, undergraduate degree requiring 60 credit hours in nutrition, food
service and other related subjects;
-1 year clinical internship or equivalent;
-pass Academy of Nutrition and Dietetics' national exam;
-maintain up-to-date knowledge and REGISTRATION)
◉ 6. Diagram and explain the "ChooseMyPlate" food guide logo.
Summarize the major recommendations for eating.
Answer: ChooseMyPlate - Logo created by the USDA to illustrate the
5 food groups; to remind consumers to make healthy food choices;
and to choose a balanced, healthful, nutrient dense diet. It divides a
plate into 4 sections, each representing a food group with varying
sizes that indicate a relative portion for each group. A circle next to
the plate represents the dairy group.
◉ 7. Trace the major steps of digestion and their function. Where is
the major site of nutrient digestion/absorption?
Answer: 1. )Food enters the mouth and travels down the esophagus
and through the upper and lower esophageal sphincters to the
stomach, then though the pyloric sphincter to the small intestine, on
through the ileocecal valve to the large intestine, past the appendix
to the rectum, ending at the anus.
2. )Mouth- during chewing, teeth crush large pieces of food into
smaller ones. Saliva contains carbohydrase, an enzyme that
