NUT 10V EXAM QUESTIONS AND ANSWERS
Nutrients - Answers -The food you eat supplies you with the nutrients you need to
renew your body.
Nutrients provides energy, serves as building materials, and are involved in maintaining
the whole renewal process
6 classes of nutrients - Answers -protein, carbs, fats, minerals, and water
protein, carbs, and fats are energy nutrients.
we have over 50 different nutrients in our body
Body composition - Answers -55-60% water, 15-25% body fat, 18-20% protein, 4-5%
minerals, and less than one percent carbs and vitamins
Men v Women, body fat and water content - Answers -Men have more lean mass (more
protein) and more water content so they have a lower body fat content, women have
higher fat and lower body water content
-inverse relationship between body fat and water content
Essential nutrients - Answers -nutrients the body cannot make (ex: calcium), or we
cannot make them at a sufficient enough rate (ex: naicin). This is why we need to obtain
them from the foods we eat.
3 basic functions of nutrients - Answers -energy, structure, and regulation
What element do all 3 energy nutrients have? - Answers -Carbon! held together by
chemical bonds that have potential and kinetic energy that is released to provide us
energy and are calculated through calories
Nutrients regulate body temperature - Answers -protein plays a role in fluid balance. As
we lose water through sweat, we have regulatory nutrients such as protein that come in
and help bring body fluid balance back to normal. Protein serves as a chemical catalyst
and is involved in all 3 functions!
RDA - Answers -Recommended dietary allowance- the amount of nutrients that will
prevent deficiencies
DRI - Answers -daily reference intake, used to promote optimal health intake and
prevent chronic diseases, and are used to set RDA and extracted from RDA to calculate
Daily Value.
Adequate intake - Answers -normal intake level where there is little risk of overdoes
True or False: Health professionals use standards called the Dietary Reference Intakes
(DRIs) when establishing nutrient intakes for planning and assessing the diets of sick
individuals. - Answers -FALSE, cannot be used for sick individuals
, Scury - Answers -Vitamin C deficiency
How is RDA set? - Answers -- determined for a variety of essential nutrients. It is set for
different age groups, sex, and physiological state.
-Designed to be averaged over several different days. Adjustments made for diet,
quality, bioavailability, and food preparation.
It is designed to be a value that meets the needs for the entire population (97%)
We don't take into account injury and illness when determining the RDA.
The Recommended Dietary Allowance (RDA) is the amount of a nutrient considered
adequate to meet the needs of nearly all ____________ people in the population. The
RDA _________ a minimum and is not an average need, but instead is a generous
value. - Answers -healthy, is not!
Daily Value - Answers -a standard that is used for food labels for the typical consumer
and compare what is in a food to what is that standard. Represents one size fits all for
package comparisons, and is a version of rda
Digestion - Answers -the process by which food is broken down into a form that can be
absorbed in the intestines
Parts of digestion - Answers -mouth, esophagus, gallbladder, stomach, small and large
intestines
1st phase of digestion - Answers -physical digestion
physical digestion - Answers -moving and grinding of food, involves chewing in mouth,
mixing with saliva, esophagus forces food down, stomach blends food into pieces,
Chemical digestion - Answers -second phase, enzyme breakdown- involves stomach,
gallbladder, & pancreas.
Pancreas - Answers -Makes digestive enzymes for proteins, carbs, and fats.
Is everything digested when we eat? - Answers -No, those that are not digested go into
the stool
absorption - Answers -the process of moving nutrients into the body or bloodstream,
and the primary site of absorption is the small intestine.
The surface of the small intestine is designed for maximum surface area through tiny
folds, called - Answers -Villi and microvilli, when we lose nutrients the surface area goes
down
