what each letter represents. - ANSWER 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. - ANSWER 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. - ANSWER 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? - ANSWER 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? - ANSWER 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? - ANSWER 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. - ANSWER Proteins,
fat, vitamins, minerals and water
There are six classes of nutrients. Name all that are organic. - ANSWER Carbohydrates, protein,
fat and vitamins
Describe in detail the role that the hypothalamus plays in determining whether or not you feel
like eating. - ANSWER 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? - ANSWER 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. - ANSWER 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. - ANSWER 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? - ANSWER 2000 x .61 = 1220
1220 calories / 4 = 305 grams of protein
There are six classes of nutrients. Name all that provide structure. - ANSWER Protein, 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 23 % of your calories from fat, how many grams of
fat should you eat in a day? - ANSWER 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. - ANSWER 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. - ANSWER 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. - ANSWER Sensory. Ex. smell of the food
Cognitive. Ex. comfort foods or habits learned from parents
Environmental. Ex. higher income families spend more going out to eat
Health Status. ex. declining taste sensitivity related to age or medication
There are six classes of nutrients. Name all that are considered macronutrients. - ANSWER
Carbohydrates, Protein, Lipids/Fats and Water
Recommended maximum % of calories from fat: - ANSWER The recommended maximum % of
calories from fat per day is 35%, with the recommended range being 20 - 35%.
