NSC-150 QUIZ 3 ACTUAL 2025 QUESTIONS AND
ANSWERS 100% CORRECT
Phytochemicals- definition and some examples Answer - Chemical compounds
produced by plants through primary or secondary metabolism
Ex. many fruits, veggies, herbs, beans/seeds, and medicinal plants
Supplements- regulations, and examples Answer - Industry worth over 40
billion
FDA regulation, but not regulated the same as food
Ex. creatine, beta-alanine, nitric oxide
What are some genetic factors related to obesity? Answer - Body type, height,
set point theory (brain, hormones, and enzymes work together to regulate
body weight and fat at a genetically predetermined level that solidifies
sometime during young adulthood)
What are some environmental factors related to obesity? Answer - Choosing
the correct foods and portion sizes and getting sufficient quantity and quality of
exercise; activities of daily living; and learning behavioral modification and self-
monitoring techniques
What health conditions are associated with obesity Answer - Increased
inflammation, sleep apnea, osteoarthritis, fatty liver, kidney disease,
depression,
, Co-morbid conditions; type II diabetes, heart disease, stroke, some types of
cancer
What is BMI- how is it calculated (what factors go in to the calculation) Answer
- Body weight and height, calculated by dividing weight in lbs by height in
inches squared then multiplying by 703
What is a normal/healthy BMI. What is obese BMI Answer - Normal/Healthy
BMI = 18.5 - 24.9
Obese BMI = 30 - 34.9 +
Does BMI work for everyone? Why or why not? Answer - No, BMI should not
be used in isolation to determine health, disease, or disease risk. BMI does not
specifically differentiate between body weight and amount of body fat. Thus,
BMI overestimates fat in those with high muscle mass. For example, a very
muscular male athlete with low body fat could have a BMI that classifies him as
overweight or obese.
What is a waist circumference that increases risk for chronic disease Answer -
35 " for females
40" for males
What is body composition? What is a healthy (acceptable) body fat percentage
for males and females Answer - Components that make up the body such as
body fat and lean body mass
Acceptable % = 15-20 m and 24-30 f
How can you estimate body composition? Answer - Methods are based on
cadavers
Hydrodensitometry
