Success
Bioelectrical Impedance Analysis (BIA) - CORRECT ANSWER -A technology that estimates body
composition based on the fluid content - by determining how easily small electrical currents
travel through the body, BIA can predict the amount of lean tissue (higher water content and
easier flow of electricity) and fat tissue (lower water content and more resistance to electrical
currents).
Skinfold Method - CORRECT ANSWER -A body composition estimation method that is based on
measuring the thickness of the fat layer under the skin - using calipers, the skin and fat are
pinched at certain locations on the body to determine their thickness. These measurements are
placed into a series of equations, which provide an estimate of body-fat percentage.
Body Density - CORRECT ANSWER -The estimated thickness of fat under the skin at specific
locations when entered into an equation.
Ultrasound Technology - CORRECT ANSWER -Uses high-frequency sound waves emitted by a
probe to visualize different parts of the body.
Circumference Measurements - CORRECT ANSWER -Measurements of the circumferences of
different body parts - these measurements provide some basic indication about the distribution
of fat in the body, although they cannot actually distinguish between muscle and fat.
,Underwater Weighing (Hydrodensitometry) - CORRECT ANSWER -A body composition
assessment method that involves the estimation of the 3-dimensional volume of the body
through measurement of an individual's body weight while they are completely submerged
under water.
Air Displacement Plethysmography (ADP) - CORRECT ANSWER -A body composition assessment
method that involves the estimation of the 3-dimensional volume of the body through
measurement of an individual's displacement of air while they sit in a sealed chamber.
Dual-Energy- X Ray Absorptiometry (DXA) - CORRECT ANSWER -A body composition assessment
method that measures whole-body and regional (arms, legs, and trunk) body composition using
low-energy X-rays.
Infrared 3-Dimensional Scanning - CORRECT ANSWER -A body composition assessment method
that involves the estimation of the 3-dimensional volume of the body using infrared sensors.
Computed Tomography (CT) - CORRECT ANSWER -Imaging procedure to create scans and
pictures of inside the body.
Magnetic Resonance Imaging (MRI) - CORRECT ANSWER -A medical imaging process that
measures the reaction of tissue nuclei to magnetic fields to produce images of inside the body.
,Hydrometry - CORRECT ANSWER -The process of monitoring water within the body to
determine body composition.
Near-Infrared Interactance (NIR) - CORRECT ANSWER -A technique using a specialized probe
against the body, emitting infrared light to estimate body composition of an individual.
Requirements of a Food Label - CORRECT ANSWER -1. The number of servings per container
2. Serving size
3. Total calories per serving
4. Amount of total fat per serving (in grams), saturated fat (in grams), and trans fat (in grams)
5. Cholesterol (in milligrams)
6. Sodium (in milligrams)
7. Total Carbohydrates (in grams)
8. Dietary Fiber (in grams)
9. Total Sugars and Added Sugars (in grams)
10. Protein (in grams)
11. Amounts and the Percent Daily Value for the following vitamins and minerals: Vitamin D,
calcium, iron, and potassium
Servings Per Container - CORRECT ANSWER -The number of servings of a food or dietary
supplement provided in a package, based on the specified serving size.
, Serving Size - CORRECT ANSWER -Reference amount for a food or dietary supplement for which
nutrition/supplement information is provided.
Portion Size - CORRECT ANSWER -The amount of food an individual chooses to serve
themselves.
Percent Daily Value - CORRECT ANSWER -The amount in a serving contributed toward the
recommended daily value for a nutrient, based on a 2000-calorie diet.
Total Sugars - CORRECT ANSWER -The total amount of sugar in a food (includes both added and
naturally occurring sugars in a food).
Added Sugar - CORRECT ANSWER -The amount of sugar that has been added to a food product
(does not include sugar that is a natural part of the food).
Reference Intakes - CORRECT ANSWER -A reference recommended amount of a nutrient for
healthy individuals.
Nutrient Density - CORRECT ANSWER -The amount of nutrients provided by a food or meal
relative to the total calories in the meal.
