BASIC CONCEPTS IN NUTRITION AND DIET THERAPY Flashcards
a state of complete physical, mental and
social well-being and not merely the absence of
disease and infirmity (WHO,n.d,para.1)
HEALTH
acdng to Dubos (1959) as cited in Green (2017)
this is the “the expression of the extent to which the
individual and the social body maintain in readiness
the resources required to meet the exigencies of
future.”
HEALTH
“The merging and balancing of the five physical and
psychological dimensions of health: physical,
mental, emotional, social, and spiritual.”
HEALTH
A lifestyle (pattern of behaviors) that enhances our
level of health
WELLNESS
science of food and nutrients, their action and
interaction, in relation to providing the body with
the necessary substances to maintain homeostasis
NUTRITION
impacts the health maintenance
and disease prevention and is essential for growth
and optimal bodily
Nutritional balance
One’s physical condition as determined by the diet
Nutritional Status
For Cellular Differentiation
Metabolism and Energy Production
Immune Health and Disease Prevention
Bone Structure and Strength
Adapting food pattern to nutritional needs
Awareness of need in specified disease
FUNCTIONS OF NUTRITION
- It is safe to eat
- It is nourishing or nutritious
- Its palatability factors (color, aroma, flavor,
texture etc.) satisfy the consumer - It has satiety value
- It offers variety and planned within the socioeconomic context
- It is free from toxic substance
FOOD QUALITIES
NUTRIENTS
NUTRIENTS
- To provide energy (Fuel Nutrients)
- To build and repair tissues (Body Building)
- To regulate life processes (Regulatory)
THREE GENERAL FUNCTIONS of NUTRIENTS
Professional trained to assess nutrition status and
recommend appropriate diet therapy
DIETITIAN
Bachelor’s Degree
Completion of Dietetic
Internship
Passed a national exam
Maintains on-going
education credits
DIETITIAN
A qualified health professional who
helps promote good health through
proper nutritional habits
DIETITIAN
An expert on nutrition
Registered with the
Commission of Dietetics
Registration (CDR
Licensed to practice diet
and nutritional consultation
DIETITIAN
None required
Self-proclaimed title
NUTRITIONIST
Someone who works
with food and
nutritional science,
aiming to prevent
diseases related to
nutrient deficiency
NUTRITIONIST
Not legally
accepted as
an expert
NUTRITIONIST
s a condition of the body resulting from the
utilization of essential nutrients
NUTRITIONAL STATUS (NUTRITURE)
body has an adequate supply of essential
nutrients that are efficiently utilized and maintained
in highest possible level
Optimal of Good Nutrition
Poor nutrition, can be either
nutritional deficiency or overnutrition and
hypervitaminosis
Malnutrition
Primary faulty diet both in quantity and
quality
Malnutrition
Secondary-multiple and include all
conditions within the body that reduce the
ultimate supply of nutrients to the cell after
the food goes beyond the mouth
Malnutrition
found in large amnts
Essential Elements
less than 0.01% of the the body mass
Trace Elements
Contains carbon
Organic compounds
Carbohydrates
Proteins
Lipids
Nucleic Acid
Organic compounds
Do not contain carbon
Inorganic compounds
Water
Minerals and Salts
Inorganic compounds
- Carbohydrates
- Protein
- Fats
- Vitamins
- Minerals
- Water
6 BASIC NUTRIENT
known as saccharides, a Greek
word, meaning sugar
CARBOHYDRATES (CHO)
are organic compounds composed of
carbon, hydrogen, and oxygen
CARBOHYDRATES (CHO)
Source of “Instant Energy”
CARBOHYDRATES (CHO)
- Monosaccharides
- Disaccharides
- Polysaccharides
Classification of Carbohydrates
Glucose
Fructose
Galactose
Galactose
Galactose
Monosaccharides
= simple sugar (one sugar unit)
Monosaccharides
also known as
dextrose, grape sugar, and
physiologic sugar. (corn syrup)
Glucose
also known as fruit
sugar or levulose. Sweetest of
all sugar. (fruits and honey)
Fructose
also known as milk
sugar. An important of brain
and nerve tissue.
Galactose
examples are
mannitol and sorbitol
Sugar alcohol
e (ribose and ribulose)-
meat and seafood
Pentose
Sucrose
Maltose
Lactose
Disaccharides
composed of two
monosaccharides (one of which is
glucose)
Disaccharides
complex
carbohydrates, composed of many
sugar units
Polysaccharides
Starch
Glycogen
Fiber
Polysaccharides
- Energy Source
- Helping to burn fat more efficiently and
completely - Aiding in normal functioning of the intestine
(fiber) - Providing laxative action and aiding in the
absorption of calcium (lactose) - Cerebroside- group of complex lipid present in
the shield of nerve fibers(galactose and
glucose)
Functions of Carbohydrate
group of complex lipid present in
the shield of nerve fibers(galactose and
glucose)
Cerebroside
Yields 4 kilocalories of energy
Protein sparring
60% of diet (50-100 grams)
Carbohydrates
- Digestion
- Absorption
- Metabolism
How the Body Handles CHO
should be in its simplest form.
Begins in the mouth. Fibers are not digested.
Digestion -
should be in its simplest form.
Begins in the mouth. Fibers are not digested.
Digestion -
takes place in intestinal mucosa
Absorption
takes place in the
liver(conserves and release glucose)
Metabolism
Principal source: Plant foods
Cereal grains
Vegetables
Fruit
Nuts
Sugar
CARBOHYDRATE FOOD SOURCES
The only substantial animal sources of carbohydrate
is
Milk
Preventing and relieving constipation
Preventing colon and rectal cancer
Reduce cholesterol
Aiding weight management
Decreasing blood glucose
FIBER
● Comes the Greek word proteios/protos meaning “to hold” or “is of prime importance”, first position or primary
