Classification of Nutrients Flashcards
Nutrients are classified according to the following:
Those that form tissues in the body are body-building nutrients while those
that furnish heat and energy are fats, carbohydrates, and proteins.
- Function
Nutrients are classified according to the following:
Nutrients are classified are either organic or inorganic
Chemical properties
Nutrients are classified according to the following:
Nutrients are classified based on their significant contribution to the body’s
physiological functioning.
- Essentiality
Nutrients are classified according to the following:
Nutrients are either in;
a. large amounts (____)
b. in little amounts (____)
high nutrient density
low nutrient density
- Concentration
- Essentiality
– nutrients required for human life; cannot be synthesized
by the body, must be consumed in food.
a. Essential –
- Essentiality
– nutrients that the body can synthesize, need not be
directly obtained from food
. Nonessential
are nutrients that provide calories or energy and are required in large
amounts to maintain body functions and carry out the activities of daily life
Macronutrients
carb intake men
200 to 330 g/-day
carb intake womenm
180 to 230 g/day
provide energy for cellular work, and help to regulate protein
and fat metabolism. They are essential for normal cardiac and central
nervous system (CNS) functioning.
Carbohydrates
As complex carbohydrates are ingested and broken down, they are easily
absorbed in the intestine and into the bloodstream where they are stored in
the____ and ___ for energy needs.
liver and muscles
__ carbohydrates together with fats and protein add bulk
to food and provide energy and other benefits to the body
Digestible
____ carbohydrates – includes most of the fibers in food,
yield little or no energy but provide other important benefit.
Indigestible
is the stored carbohydrate energy source found in the liver and
muscles. It is a vital source of backup energy.
Glycogen i
Carbohydrates provide____cal/g of energy
4
___ is categorized as a carbohydrate, but it does not yield energy for the
body
Fiber
- derived from inside plant cells and decreases
cholesterol, regulates blood glucose levels, and increases satiety
Soluble fiber -
– derived from structural parts of plants that
promote regularity and decreased risk of cancer and diverticular
diseases. (sources: wheat bran and nuts)
Insoluble fiber
Carbohydrates are divided into three groups:
monosaccharides, disaccharides,
and polysaccharides.
is the process in which protein is converted to
glucose.
Gluconeogenesis
