Study Questions With Answers For Nutrition, 3e
Chapter 1
1. What are the main factors that influence our food choices?
Sensory, cognitive, and cultural
2. How do our health beliefs affect our food choices?
Health beliefs are characterized by an individual’s perception that he or she is
susceptible to a disease and, if so, that action can be taken to prevent or delay its
onset. People who feel susceptible to a disease are more likely to heed
recommendations based on information about the links between dietary choices and
the risk of that disease. They see that dietary changes may lead to positive results.
3. List the six classes of nutrients.
Carbohydrate, protein, fat, vitamins, minerals, and water
4. List the 13 vitamins.
Fat-soluble: vitamin A, vitamin D, vitamin E, and vitamin K
Water-soluble: thiamin (B1), riboflavin (B2), niacin (B3), pyridoxine (B6), cobalamin
(B12), folate, pantothenic acid, biotin, and vitamin C
5. What determines whether a mineral is a macromineral or a micro (trace)
mineral?
Macrominerals are found in and used by the body in the largest amounts.
Microminerals are found in and used by the body in smaller amounts.
6. How many kilocalories are in 1 gram of carbohydrate, of protein, and of fat?
Carbohydrates have 4 kilocalories per gram; proteins have 4 kilocalories per gram;
and fats have 9 kilocalories per gram.

7. What is an epidemiological study?
An epidemiological study observes and compares how disease rates vary among
different population groups and identifies conditions related to diseases or conditions
within the populations. This enables researchers to identify associations between
factors within the population and the particular disease being studied.
8. What is the difference between an experimental group and a control group?
Subjects in the experimental group experience an intervention, while subjects in a
control group have similar characteristics and are not treated. Specific elements of
health or disease are measured and compared between the two groups.
9. What is a placebo?
A placebo is an imitation treatment (such as a sugar pill) that looks the same as the
experimental treatment (such as a sugar pill) but has no effect. The placebo is
important for reducing bias because subjects do not know if they are receiving the
intervention and are less inclined to alter their responses or reported symptoms based
on what they think should happen.
Chapter 2
1. Define undernutrition and overnutrition.
Undernutrition is poor health resulting from the depletion of nutrients due to
inadequate nutrient intake over time. It is most often associated with poverty,
alcoholism, and some types of eating disorders.

The most common type of overnutrition in the United States is due to the regular
consumption of excess calories, fats, saturated fats, and cholesterol.
2. What is the purpose of the Dietary Guidelines for Americans? List the nine
focus areas of the 2005 Dietary Guidelines for Americans.
The purpose of the Dietary Guidelines for Americans is to provide science-based
advice to promote health and to reduce risk for chronic diseases through diet and
physical activity. The nine focus areas are:
Adequate nutrients within calorie needs
Weight management
Physical activity
Food groups to encourage
Fats
Carbohydrates
Sodium and potassium
Alcoholic beverages
Food safety
3. What are the recommended amounts for each of the food groups of MyPyramid
for a 2,000-calorie diet?
Grains: 6 ounce–equivalents; half should be whole grains
Vegetable group: 2 ½ cups
Fruits: 2 cups
Milk: 3 cups
Meat and beans: 5 ½ ounce–equivalents
