1
New cards
Quality, Frequency, Stability
What are the three factors that should be considered when selecting food?
2
New cards
Metabolism
This refers to the chemical changes which take place in cells and tissues which are necessary for the fulfillment of vital functions.
3
New cards
Basal Metabolism
It refers to the sum of all internal working activities of the body at rest.
4
New cards
Oxidation
During metabolism, nutrients are combined with oxygen within each cell. This is called?
5
New cards
Anabolism
This is the process wherein released energy is used to build new substances from simpler substances.
6
New cards
Catabolism
This is the process that involves the breakdown of complex molecules into simpler substances to obtain energy.
7
New cards
Thyroxine and Triiodothyronine
These are secretions of the thyroid gland primarily governing metabolism.
8
New cards
Energy
This refers to the capacity to do work and is used whenever voluntary or involuntary activity is performed.
9
New cards
Kilojoule (kJ)
This refers to the unit of energy in the metric system of measurement.
10
New cards
Kilocalories (Kcal)
This refers to the unit of measuring energy in food and for the body’s needs.
11
New cards
Bomb Calorimeter
It refers to an instrument that measures the energy value of food by burning it completely in a container surrounded by water.
12
New cards
Energy Density
This refers to the amount of energy or calories per gram of a particular food item.
13
New cards
Water and fiber
What are the two components that lowers the energy density of foods?
14
New cards
High energy density
Also known as nutrient-poor, it is associated with overeating, excess intake of calories, and weight gain among others.
15
New cards
Low energy density
Also known as nutrient-rich, it is associated with favorable nutrient intakes and reduced weight gain.
16
New cards
Negative Energy Balance
This occurs when energy intake is less than the energy needed for expenditure, which can lead to weight loss.
17
New cards
Positive Energy Balance
This occurs when energy intake is more than the energy needed for expenditure, which can lead to weight gain/obesity.
18
New cards
Basal Metabolism
What is the energy expenditure for carbohydrates?
19
New cards
Activity
What is the energy expenditure for proteins?
20
New cards
Thermic Effect of Food
What is the energy expenditure for fats?
21
New cards
Basal Metabolic Rate
It refers to the rate at which the body expends energy for activities at rest for an hour or hours.
22
New cards
7, 1
There is a __% increase in energy expenditure for every __ degrees-Fahrenheit elevation above normal body temperature.
23
New cards
Specific Dynamic Action/Thermogenic Effect
This refers to the heat produced by cellular activity during digestion, absorption, and metabolism.
24
New cards
300, 500
During periods of growth, pregnancy, and lactation, the following additional energy is required:

\

1. __kcal/day during the second and third trimester
2. __kcal/day during the entire lactation period
25
New cards

4.184

How many kJ is in 1 kcal?

26
New cards

Number of calories/gram

How do you compute for energy density?
