NDT MIDTERMS [DECK 1] Flashcards
means big – big nutrients.
○ the main nutrients that make up the foods we eat.
○ Nutrients required in large amounts that provide the
energy needed to maintain body functions and carry
out the activities of daily life.
Macronutrients
are essential elements needed by life
in small quantities.
○ Just like water do not provide
energy, however, the body need adequate amount
to ensure that all body cells function properly.
○ can only be obtained from the
food in which we eat.
Micronutrients
CARBOHYDRATES kind of nutrient
MACRONUTRIENTS
Considered as the primary source of fuel for the brain and the
rest of the body.
CARBOHYDRATES
50% - 70% of total energy requirement
CARBOHYDRATES
1 gram CHO = __ calories upon complete hydrolysis
4
Has sugars (composed mainly of SUGARS)
CARBOHYDRATES
CARBOHYDRATES is an Organic compounds composed of
carbon, hydrogen, and oxygen
“saccharide” meaning
starches and sugars
CARBOHYDRATES Derived from the Greek word
saccharide
Chiefly found in plants and produced by the process of
photosynthesis from H2O, CO2, and sun
CARBOHYDRATES
The building blocks are called
monosaccharide.
The digestion begin in the mouth with salivary amylase
released during the process of - and are absorbed
across the membrane of the small intestine and transported to
the liver distributed to the rest of the body.
chewing
The absorption process begins around - hours after eating
3-6
simplest form of sugar
Monosaccharides
Considered as the simplest form of sugar of sugar
which is small molecules that require little or no
digestion before they can be used by the body and
the source is the digestive end product of lactose
hydrolysis.
Monosaccharides
Glucose is a CARBOHYDRATES under
Monosaccharides
Physiologic sugar
Glucose
blood sugar
Glucose
dextrose
Glucose
grape sugar
Glucose
principal form used by the
body
Glucose
Moderately sweet sugar
Glucose
Glucose works for
brain, nerve cells, RBC
Stores last for only hours
Glucose
a process where
protein is converted to glucose
Gluconeogenesis
less available CHO for energy –
more fats to be broken down – form
ketone bodies.
Ketosis
Glucose Sources
fruits, sweet corn,
corn syrup
red
Lycopene
Carotene
orange, yellow
Anthocyanin
blue, violet
Cruciferae
green, white
Fructose is a CARBOHYDRATES under
Monosaccharides
“Fruit sugar”
Fructose
sweetest of all sugar
Fructose
“levulose”
Fructose
Fructose Sources:
Ripe fruits and honey
Galactose is a CARBOHYDRATES under
Monosaccharides
Not found in nature, not found in free
foods
Galactose
Produced from lactose (milk sugar) by
digestion and is converted to glucose
Galactose
