HNF 150 Exam 2 Prep Questions With Complete Solutions
Why are lipids in a healthy diet essential, and what's the
difference between energy density and nutrient density?
A) Lipids provide essential nutrients, and energy density
measures calories per food volume.
B) Lipids supply nutrients, and energy density assesses food's
calorie concentration.
C) Lipids support health, and energy density relates to food
volume.
D) Lipids contribute to nutrition, and energy density evaluates
food's vitamin content.
B) Lipids supply nutrients, and energy density assesses food's
calorie concentration.
What are the essential fatty acids, and why are they vital for
health?
A) Omega-6 and omega-9; they help manage cholesterol levels.
B) Linoleic acid (omega-6) and alpha-linolenic acid (omega-3);
they're necessary because the body can't produce them and play
,crucial roles in body functions.
C) Saturated and trans fatty acids; they provide energy for
activity.
D) Palmitic and stearic acids; they support cell membrane
structure.
B) Linoleic acid (omega-6) and alpha-linolenic acid (omega-3);
they're necessary because the body can't produce them and play
crucial roles in body functions.
What are the primary roles of LDL and HDL in lipid transport in
the body?
A) LDL carries cholesterol away from cells, while HDL delivers
cholesterol to cells.
B) LDL is responsible for transporting dietary fats, and HDL
assists in fat storage.
C) LDL carries cholesterol to cells and can contribute to
atherosclerosis, while HDL removes excess cholesterol from
tissues and is protective against cardiovascular diseases.
D) LDL and HDL have the same functions and can be used
interchangeably in lip
,C) LDL carries cholesterol to cells and can contribute to
atherosclerosis, while HDL removes excess cholesterol from
tissues and is protective against cardiovascular diseases.
What is atherosclerosis, its causes, and the roles of LDL and
HDL? What can cause vascular injuries?
A) Atherosclerosis is arterial cancer caused by sugar. HDL is
good cholesterol, and LDL is bad cholesterol. Vascular injuries
result from high blood pressure, smoking, and high cholesterol.
B) Atherosclerosis is artery narrowing due to fatty deposits
(plaque). LDL contributes to plaque, while HDL removes
cholesterol. Vascular injuries result from high blood pressure,
smoking, and high choles
B) Atherosclerosis is artery narrowing due to fatty deposits
(plaque). LDL contributes to plaque, while HDL removes
cholesterol. Vascular injuries result from high blood pressure,
smoking, and high cholesterol.
What were the 2015-2020 Dietary Guidelines for trans and
saturated fat intake?
A) No trans or saturated fat consumption was recommended.
B) Minimize trans fat intake, limit saturated fat to less than 10%
of daily calories.
C) Consume high levels of trans and saturated fat for energy.
, D) The guidelines had no specific recommendations for trans
and saturated fat.
B) Minimize trans fat intake, limit saturated fat to less than 10%
of daily calories.
The American Heart Association recommends eating fatty fish
every week. Which nutrient is this recommendation based upon?
A) Vitamin D
B) Omega-6 fatty acids
C) Omega-3 fatty acids
D) Iron
C) Omega-3 fatty acids
Why are other agencies recommending that Americans eat less
fish?
A) High sodium content
B) Concerns about environmental sustainability and mercury
contamination
C) Fish allergies
