ANSWERS 2026/2027 UPDATE
leading causes of death attributed to nutrition
1. Heart Disease
2. Cancer
3. Stroke
4. Diabetes
Factors Influencing Food Choices
availability, health concerns, culture, psychological and emotional state, social acceptability,
personal preference
____________________ occurs when an individual is using a mask or mouthpiece to
breathe into in order to determine the amount of oxygen consumed vs. amount of
CO2 expired.
a. Direct Calorimetry
b. Indirect Calorimetryc. Doubly-Labeled Water
d. None of the above
indirect calorimetry
direct calorimetry
individual is in a metabolic chamber
indirect calorimetry
energy is measured using a mouthpiece or mask
double-labeled water
involves injection of hydrogen, oxygen isotopes
health risk factors for being overweight: heart disease
,increase amount of work completed by the heart, increase risk of high blood pressure and
triglycerides and LDL cholesterol
health risk factors for being overweight: stroke
block supply of blood to the brain or when a blood vessel in the brain bursts
health risk factors for being overweight: gallbladder disease
gallstones, cholesterol clusters, accumulate in the bile duct of the gallbladder, bile duct
blockage, impaired lipid absorption in the small intestine
health risk factors for being overweight: cancer
excess body weight and fat are associated with cancer risk
health risk factors for being overweight: joint disorders
cartilage cushioning of joints wear down and become rough and thin in appearance,
continuous breakdown of cartilage causes the bones on the joints to rub against each other
resulting in the reduction of movement and increased pain
When assessing body composition of an individual, which of the following involves
passing a current through the body to determine the resistance, which is
proportional to body fat?
a. Bioelectric Impedance
b. Skinfold thickness
c. Underwater Weighing
d. BodPod
a. Bioelectric Impedance
bioelectric impedance
Directing a low-energy electrical current through the body and the resistance to flow is
calculated
Fat: poor conductor to electricity → resistant to the current
Skinfold Thickness
Measurement of subcutaneous fat (located under the skin), used to estimate total body fat
Areas of Measurement:
Triceps (back of the upper arm)
Subscapular area (below the shoulder blade)
,underwater weighing
Individual is weighed on land and on water
Difference is used to determine body volume and body density, which is proportional to fat-
free mass
% Body Fat is determined using a standardized equation
air displacement
Individual is assessed in an air-filled chamber called BOD POD
Accurate, more convenient
Expensive
dilution methods
Injection of water-soluble isotope in the blood stream mixing with the water in the body
Isotope concentration in body fluid is measured to determine the amount of lean body
tissue, followed by body fat
Expensive and invasive
radiologic methods
•Dual-Energy X-Ray Absorptiometry (DXA)
•Body mass, bone mineral mass, % body fat
•Visceral Fat: Adipose tissue in the abdomen surrounding the body's organs
•Expensive
leptin
Protein hormone that helps regulate adipose cell size
Hormone that returns adipocyte to set point due to less fat intake
It decreases energy intake and increases energy expenditure
increased release when gain weight
ideal weight loss program
decreasing energy intake, increasing physical activity, modifying behavior
If there is 500 kcal deficit/day from foods and beverages, then 1 pound may be lost per
week
Or, reduce 250 kcal/day from foods and beverages and expend 250 kcal/day with planned
exercise
, ABCs related to Behavior Modification
1. Identify the antecedent
2. Recognize the behavior
3. See the consequence
4. Modify the behavior
5. Enjoy the new consequence
Grehlin, Cholecystokin, and Peptide YY are _______________ hormones
short term
grehlin
Peptide hormone produced in stomach that stimulates food intake prior to meals
Levels are elevated 1-2 hours prior to meal and decrease after meal consumes
Cholecystokinin (CCK)
Released by small intestine when chyme enters
Hormone responsible for delayed stomach emptying and signals the brain when to stop
eating
Peptide YY
Hormone released from GI tract and signals reduction in appetite
The amount released is proportional to the amount of calories in a meal
During the process of digestion and absorption, fat-soluble vitamins are incorporated
into micelles.
a. True b. False
true
thiamin dietary source
pork
riboflavin dietary source
milk
niacin dietary sources
chicken
biotin dietary sources
