BIOD 121 FINAL EXAM REVISION
QUESTIONS AND CORRECT ANSWERS
An individual's health can be assessed using the
ABCDE's of nutritional assessment. Indicate what
each letter represents.
A - Athropometrics- measurements of body composition
such as height and weightB - Biochemical- measurement
of nutrients in blood, urine and fecesC - Clinical - physical
exam and general appearanceD - Dietary- review of
dietary intake and assessmentE - Environmental-
background, family history, life style and living conditions
List and define the three states of nutritional health.
Desirable nutrition is achieved by eating a variety of foods
which provide all the essential nutrients to support normal
body functions.
Over-nutrition is the excess consumption of calories, fats,
saturated fats and cholesterol which increase the risk for
chronic disease.
Under-nutrition occurs when nutrient intake does not meet
nutrient needs and over time health begins to decline.
There are six classes of nutrients. Name the three that
supply energy.
carbohydrates, proteins, and fat
The current recommendation to maintain your body
weight is 2000 calories daily. If you are told that you
should not consume any more than 52 % of your
,calories from carbohydrates, how many grams of
carbohydrates should you eat in a day?
2000 x .52 = 1040
1040 calories / 4 = 260 grams of carbs
If a fudge brownie has 9 grams of carbohydrates, 1
gram of protein and 12 grams of fat. How many
calories are in the brownie?
Carb: 9 x 4 = 36
Pro: 1 x 4 = 4
Fat: 12 x 9 =108
36 + 4 + 108 = 148 calories
If a fudge brownie has 12 grams of carbohydrates, 2
grams of protein and 10 grams of fat. How many
calories are in the brownie?
Carb: 12 x 4 = 48
Pro: 2 x 4 = 8
Fat: 10 x 9 =90
48 + 8 + 90 = 146 calories
There are six classes of nutrients. Name all that
regulate body processes.
Proteins, fat, vitamins, minerals and water
There are six classes of nutrients. Name all that are
organic.
Carbohydrates, protein, fat and vitamins
Describe in detail the role that the hypothalamus plays
in determining whether or not you feel like eating.
Hunger center of the brain. Helps to determine hunger,
appetite, and satiety.
When we have not eaten for a period of time, the amount
of nutrients in the blood begin to decline. This drop
,stimulates the feeding center in the hypothalamus which
signals us to eat. When the nutrient level of the blood
begin to rise, the satiety center is activated and our desire
to continue to eat declines.
If a fudge brownie has 22 grams of carbohydrates, 2
gram of protein and 16 grams of fat. How many
calories are in the brownie?
Carb: 22 x 4 = 88
Pro: 2 x 4 = 8
Fat: 16 x 9 =144
88 + 8 + 144 = 240 calories
Explain the differences between hunger and appetite.
hunger: internal drive, negative sensation
appetite: external drive, positive sensation
Hunger is the internal drive to find and eat food. It is often
experienced as a negative sensation. Appetite is the
external drive that encourages us to find and eat food. It is
related to pleasant sensations associated with food.
MyPlate illustrates 3 concepts. Name the concepts.
The three concepts:
Balance, variety and moderation
The three key dietary principles of the Dietary Guidelines
are
1. Meet nutritional needs primarily from nutrient dense
foods and beverages
2. Choose a variety of options from each food group
3. Pay attention to portion size
The current recommendation to maintain your body
weight is 2000 calories daily. If you are told that you
, should not consume any more than 61 % of your
calories from protein, how many grams of protein
should you eat in a day?
2000 x .61 = 1220
1220 calories / 4 = 305 grams of protein
There are six classes of nutrients. Name all that
provide structure.
Protein, fat, mineral and water
The current recommendation to maintain your body
weight is 2000 calories daily. If you are told that you
should not consume any more than 23 % of your
calories from fat, how many grams of fat should you
eat in a day?
2000 x .23 = 460
460 calories / 9 = 51.1 grams of fat
Name the key hormone that causes a feeling of
hunger. Indicate where in the body it is produced and
the process by which it operates.
Ghrelin is produced by the stomach and travels to the
brain to stimulate the hunger center as it deactivates the
satiety center.
Name the key hormone that causes a feeling of
satiety. Indicate where in the body it is produced and
the process by which it operates.
Leptin is produced by the fat cells which are also known
as adipose tissue. The role of leptin is to alert the brain to
turn off the hunger center and activate the satiety center
when consuming a meal.
Name the four types of external forces that influence
our eating habits and patterns and give an example of
how you experience each in your life.
