HNF 150 EXAM QUESTIONS WITH
DETAILED VERIFIED ANSWERS
What is Nutrient density and how can it be used to determine the healthfulness of foods?
lower calories and higher nutrients
• eat less, or the same amount while providing what your body needs
What are the 6 classes of nutrients?
Carbs, Protein, Fat, Water, Vitamins & Minerals
Energy yield for Carbohydrates
4 kcal/g
Energy yield for Protein
4 kcal/g
Energy yield for Fat
9 kcal/g
Energy yield for Alcohol
7 kcal/g
Characteristics of a nutritious diet
Adequacy, Balance, Calorie control, moderation & variety
Adequacy
meat / fish / poultry / legumes ~ iron rich
Balance
choosing dairy products & iron rich foods
Variety
Don't eat the same foods everyday
,Moderation
fat intake below 35% of cal, too much fiber leads to nutrition losses & enough leads to healthy
digestion
Calorie control
energy intakes (food consumption) not exceeding energy expenditures (exercise)
Whole Foods definition
foods that form the basis of a nutritious diet (basic foods)
Examples of whole foods
Milk, fruit, veggies, meat and grains
Processed foods
Foods subjected to any process
• milling
• alteration of texture
• addition of additives
• cooking
Enriched foods
Adding something that is lost in processing
• fiber rich white bread
Fortified
Adding something that isn't naturally there
• Calcium orange juice
Functional foods
Have benefits like reduced disease risk
• oats reduce LDL
, Recognize cues within nutrition information that could be misleading in advertising and
media
• "Trans or Saturated fat free" ~ less than .5 gram per serving
• overrates importance of findings, taking actions because of a single study, overstating
benefits of absence of something
Identify credible sources and credentials of experts in the field of nutrition who provide
reliable nutrition information
- Peer reviewed journals, researchers methods included (research journals)
• define subjects, present old findings
Who is responsible for the site? Do the names and credentials of info providers appear? Are links
with other reliable info sites provided? Does the site charge a fee to gain access?
Essential nutrients
Must be obtained from an external source
• omission of substance leads to health decline but reoccurrence causes recovery --- Must have
an identified biological function
Nutrient density
foods rich in nutrients relative to their energy content (calories) --- usually whole foods -- lower
calories -- higher nutrients
Energy-yielding nutrients
use for energy or building blocks macronutrients
• carbs, lipids, proteins
Organic/Inorganic nutrients
nutrients that contain carbon or don't
• carbs, fat, protein, vitamins
Calorie
