STRAIGHTERLINE NUTRITION FINAL
COMPREHENSIVE EXAM QUESTIONS AND
SOLUTIONS STUDY GUIDE
●● nutrient density
Answer: The ratio derived by dividing a food's nutrient content by its
calorie content. When the food's contribution to our nutrient need for
that nutrient exceeds its contribution to our calorie need, the food is
considered to have a favorable nutrient density.
●● added sugars
Answer: sugars and syrups that are added to food during processing or
preparation
●● energy density
Answer: A comparison of the calorie (kcal) content of a food with the
weight of the food. An energy-dense food is high in calories but weighs
very little (e.g., potato chips), whereas a food low in energy density has
few calories but weighs a lot, such as an orange.
●● What do variety, proportionality, and moderation mean, and how do
they work together to result in a healthy diet?
Answer: -VARIETY MEANS EATING MANY DIFFERENT
FOODS:Variety in your diet means choosing foods from all the food
, groups and subgroups, rather than eating the "same old thing" day after
day. Variety makes meals more interesting and helps ensure that a diet
contains sufficient nutrients. A variety of foods is best because no one
food meets all your nutrient needs.
-PROPORTIONALITY MEANS EATING MORE NUTRIENT-DENSE
FOODS:Proportionality, also referred to as balance, is eating more of
nutrient-dense foods and beverages such as fruits, vegetables, whole
grains, and fat-free or low-fat milk products, and less of foods high in
certain types of fat, sugars, cholesterol, salt, and alcohol. Balance also
refers to matching your energy intake (how many total calories you
consume) with energy expenditure (calories burned by metabolism and
physical activity) over time.
-MODERATION REFERS MOSTLY TO PORTION SIZE: Eating in
moderation requires paying attention to portion sizes and planning your
day's diet so that you do not overconsume any nutrients. It is especially
important to choose foods that help you limit intake of animal fat, added
sugars, cholesterol, salt, and alcohol. Americans typically consume too
much of these food components—and too many calories overall.
●● How do the concepts of nutrient density and energy density differ?
Answer: The nutrient density of a food is a characteristic used to
determine its nutritional quality. Nutrient density of a food is determined
by comparing its protein, vitamin, or mineral content with the amount of
calories it provides. A food is deemed nutrient dense if it provides a
large amount of a nutrient for a relatively small amount of calories when
