NUTRITION IN PUBLIC HEALTH Flashcards
The science of foods and the substance that they contain,
their action, interaction and balance in relation to health
and disease
nutrition
Includes the processes by which an organism ingests,
digests, absorbs, transports, utilizes and excretes food
substances
nutrition
- Any substance the body can take in and assimilate
- Essential for life
- Derived from plant and animal sources
- Provide energy and nutrients
- Used by the body for maintenance, growth and repai
food
6 factors affecting food consumption:
- biological needs
- social & cultural factors
- economic factors
- physical factors
- time factors
- psychological factors
- Higher incomes result to greater food choice and
higher education - Low incomes are associated with unbalanced diets in
developing countries
economic factors
- Rural or urban location
- Access to transport increases consumer choices
- Accessibility and availability of food
physical factors
- Lack of time leads to consumption of convenience
foods - Key to improve diet is improve quality of convenience
foods
time factors
- Emotional eating
- External cues
- Esteem - prestige, feeling of accomplishment, social
acceptance
psychological factors
Components of food required for body’s functioning
nutrients
4 roles of nutrients
- Provide energy
- Building material
- Maintenance and repair
- Support growth
categories of nutrients
- Water
- Carbohydrates
- Fats
- Proteins
- Vitamins
- Minerals
- Condition of the body resulting from the ingestion and
utilization of nutrients - Foods consumed have a cumulative effect on your
body - Well chosen array of foods will prevent malnutrition
nutritional status
- Nutrient deficiencies (Undernutrition)
- Nutrient excesses (overnutrition)
- Nutrient imbalances
malnutrition
- Theory and practice of nutrition as science through
organized community effort
Public Health Nutrition
Prevention, promotion , protection , conservation of
health through proper nutrition
public health nutrition
Focuses on nutrition issues affecting the whole population
rather than specific dietary needs of the individual
public health nutrition
Takes into account the impact of food production, ,
distribution, and consumption on the nutritional status and
health of particular population groups
public health nutrition
5 major nutrition problems
- Protein Energy Malnutrition
- Vitamin A Deficiency disorders
- Iron Deficiency Anemia
- Iodine Deficiency disorders
- Obesity

basic food groups:
- body building
- energy giving
- body regulating
These are foods that make the body grow. These are
foods rich in protein, iodine, iron and vitamin B.
body-building foods
These are foods that give us energy we need in doing
everyday task. Foods are rich in carbohydrates and
fats (e.g. potato, bread, butter, corn, cassava, coconut
milk).
energy-giving foods
These are foods that keep all or organs working and in
good condition, help in fighting common illnesses.
These foods are rich in vitamins and minerals (e.g.
green leafy vegetables fruits)
body-regulating foods
- Essential for growth and repair of body tissues since they
constitute the major part of the body’s building blocks - Vital in the regulation of body processes
- The source are fish, poultry, meat, eggs, dried beans
protein
Clinical constellation of edema and undernutrition
(protein and energy lack)
kwashiorkor
A physiological adaptation to marked restriction of
dietary energy
marasmus
- Main source of energy for man
- There are three major types of dietary carbohydrates:
starch, sugar and fiber - It modulate the production of insulin and other hormones
as well as synthesis of lipoproteins and cholesterol - Dietary fiber provides bulk resulting in the modulation of
peristalsis movement and the prevention of constipation
carbohydrates
- Essential nutrients, beneficial if consumes in the right
amount and if is of the right type - Concentrated source of energy
- Provides essential fatty acid
- Also helps absorb and store fat-soluble vitamin S
fats
- Essential nutrients, beneficial if consumes in the right
amount and if is of the right type - Concentrated source of energy
- Provides essential fatty acid
- Also helps absorb and store fat-soluble vitamin S
fats
- Organic compounds essential in the diet for normal
growth and maintenance of life - They are active in the regulation and metabolism and
transformation of energy
vitamins
vitamins that maintains normal vision, bone and tooth growth, reproduction, hormone synthesis, immunity, prevents xerophthalmia
vitamin A
(retinol, retinoic acid)
mineralization of bones, prevents rickets & osteomalacia
vitamin D
(calciferol)
anti-oxidants, protects neuromuscular system, helps prevent arteriosclerosis
Vitamin E
(tocopherol)
necessary for nomal blood clotting 7 synthesis of proteins found in plasma, bone, kidneys
vitamin K
(napthoquinone)
supports normal apetite, nervous system functions, prevents beri-beri
