All over the world, feeding has been and it is still one of the characteristics of every living thing which man is among sequel to this, food is one of the basic necessities of life. It does not just keep living things alive but also invigorates growth and development as well as builds up immunity for protection against diseases. In other to achieve all these benefits of feeding, one has to eat a right through making adequate choice of food. This is to state that there are various classes of food with its own distinct nutrient which requires certain amount of combination with others to produce that which the body requires for its metabolism. It is unfortunate that not everybody is aware of the ways one could eat food that contains all the food nutrients in the right proportion thus eats anything food which does more harm than good. There is need for sensitization of the rural dweller in particular on good nutrition practice, which should be carried out through the community health services. The community health services/primary health services are the grass root health workers who are rooted in the interior villages to oversee the health related cases of the community members. Stemming from the above expressions, this paper tries to x-ray the concept of nutrition, benefits of good nutrition, factors militating against good nutrition, reasons for nutrition education, the concept of Primary health services, primary health types, principles of community health services and the challenges facing them in the discharge of their duties. Suggestions were also made based on the findings.

Nigeria is one of the developing countries of the world that have
many poverty stricken homes. This is evinced going by the massive
unemployment that bedevilled the country over the years. Many
Nigerian families cannot put food on their table on daily basis. Ugwu,
Amadi [1] gave credence to the above declaration when the scholars
submitted that many Nigerians could not afford good nutrition due
to the amplified poverty level in the country. This has resulted to
alarming increase in crime rate like armed robbery, kidnapping,
internet fraud, child labour among others. It has also resulted to
people being diseased of one ailment or the other resulting to high
rate of maternal and infant mortality rate as this people are the
most vulnerable when it comes to poor nutrition. Furthermore,
many Nigerian parents are illiterate and do not know what and
what makes for a balanced diet and as such make wrong choice of
food thus eat imbalanced diet thus make their choice according to
what they like and that which they can afford. Nutrition is basically
the process of feeding or eating of food which may be in solid or
liquid form. It is the way food substances are injected into the body
by way of eating or drinking. That which is eaten or drank have
different types of nutrients which reflects in the types of food. Then
for one to know what food to eat for a particular nutrient requires
some enlightenment. In support of the above claim, Sharma [2]
succinctly put that nutrition is the study of how what is injected in
the body as food or drink affects the entire body system bearing in
mind the components of essential nutrients the body require for
good functioning. This public awareness on nutrition education is
basically provided by the community health services.
Community health services is a kind of health related aid given
to people in the rural community to avail them the opportunity of
being aware of certain ailments, causes, prevention and treatment.
Food nutrition education is one of the essential training given to
the rural dwellers as well as personal hygiene. Segen’s Medical
Dictionary [3] laid weight to the above view point and lucidly put
that community health service is a type of food which enables the
recipients to obtain health related information from the health
officials/professionals. The scholar stressed that these health professionals supply medical, dental, nursing and other related
health care services at a designated place. They also give health care
to people identified with physical and/or mental health conditions,
pregnant mothers, nursing mothers, the aged and other people
who needed community care services. Health services offered in
the community include prevention services, intervention or health
promotions as demanded by the community. In view of the above
avowals, community health services are meant to oversee the overall
wellbeing of the entire community members. In dealing with their
health issues, the awareness of the appropriateness in the choice of
food should be prioritized because good nutrition makes for good
health while malnutrition is deficiency in human health. The health
professionals educate the pregnant and nursing mothers on which
food to feed on during that period for optimal health achievement
among others. This is crucial because we are what we eat therefore,
good nutrition translates to healthy individual who are more
productive to promote the nations per capita income thus a boost
in national growth and development.
Nutrition is the types of food and drink people take into the
body system and the using up of those food elements to generate
energy, repair worn out tissues, growth physically and develop
psychologically in an appreciable level. Sharma [2] described
nutrition as the way people select what they eat. The scholar
emphasized that poor nutrition could result to a lack of energy,
digestive problems, food allergies, weigh gain, depression and
anxiety disorder as well as other chronic diseases like coronary
heart disease, cancer, Attention Deficit Hyperactivity Disorder
(ADHD). Continuing, she emphasized that nutrition education could
assist in this direction by inducing people make informed decisions
on the choice of food to eat thus attain optimal healthiness in one’s
life time. Similarly, Stare and McWilliams (1977) in Ogwudire-
Chukwudire [4] reiterated that nutrition is the process of learning
about food types and the functions they perform in human body.
This is imperative because different types of food substances have
their discrete nutrients which perform distinct functions to the
body for a healthier living and anything short of that amounts to
malnutrition which could equally result to body malfunctioning.
In his own submission, Davis [5] posited that nutrition is
a systematic way of eating food and making use of it to grow,
metabolise and carry out body repairs. According to the scholar,
nutrition under goes the following sequence; ingestion, absorption,
transport, assimilation and excretion. In other to ascertain that all
these phases of nutrition is functional, there is absolute need to
have a broad knowledge of food types and their nutritional value,
the proportion to be taken as well as the quality of the food. When
all these are given adequate consideration, a healthy life is assured
and the process of eating correctly is termed good nutrition. On the
reverse side is malnutrition (poor nutrition) which is responsible
for ill health conditions like loss of energy, anaemia, stomach
cramp, illness and eventual death. Based on the heels of the above
development, Biology Educare [6] observed that food is a necessity
to every living organism for growth, maintenance of life, energy
and so on and states that nutrition is a process through which food
we eat are broken down from complex food materials to simple
substances which the body requires for proper functioning. The
nutrient which is contained in the food need to be consumed in
specified proportion. Some are needed in large proportion while
some are be consumed in small proportion. These gave rise to types
of nutrients.
Types of Nutrients
Food nutrients are the substances contained in the food which
results to good health and are of two types depending on the
quantity required in human body thus.
a) Macro nutrients: these are those food substances that the
body require in large quantities for proper maintenance of
the body like carbohydrates, lipids or fats and protein. These
nutrients give the body required energy to function.
b) Micro nutrients: these are those food substances the body
require in small quantity for proper maintenance. These
nutrients plays essential role in the protection, growth
and development of the organism. Any deficiency in these
micronutrients can result to sickness. Examples are vitamins,
minerals, salt and water.
Owing to the different types of nutrient in the food, foods are
categorized into two namely:
a) Proximate principles of food: these food substances are
energy given food. They supple the energy for production,
body maintenance, growth and development. Examples are
carbohydrate, lipid or fat and protein.
b) Protective principles of food: they are so called because of
their ability to fight disease and assist in the metabolism of
food examples are vitamins, minerals, water and salt.
Types of Nutrition
There are two main types of nutrition viz.
a) Autotrophic nutrition: this is the process of using solar
energy by green plants and some bacteria to produce their
own food by themselves from simple organic substances such
as water, mineral salts and water. This mode of nutrition is
known as photosynthesis.
b) Heterotrophic nutrition: all non-autotrophic organisms
depend on autotrophic organisms for food and are therefore
referred to as heterotrophys. Heterotrophs are animals and
non-photosynthesis plant which cannot produce food on their
own.
Types of Heterotrophic Nutrition
There are four types of heterotrophic nutrition namely.
a) Holozoic nutrition: The term ‘holozoic’ is derived from the
Latin word ‘holo’ which means whole and ‘zoikos’ meaning animals. It implies that the animals take their food whole. It is
a type of heterotrophic nutrition which is characterized by the
injection of the organic matter. It exhibited by most free-living
animals and protozoa such as human and amoeba respectively.
this implies feeding on organic matter procured from
organisms and digestion takes place within the organism. The
organism does not produce its food. It has five stages namely;
feeding, digestion, absorption, assimilation and ejection.
b) Saprophytic nutrition: this feeding on dead or decomposing
organic matter and digestion begins outside of their body
which is referred to a chemoheterotrophic extracellular
digestion. This mode of nutrition takes place in the presence of
water, oxygen, neutral-acidic pH content and low to medium
temperature optimally room temperature. Fungi, moulds,
some bacteria and some protists obtain their food from dead
and decaying organic matters,
c) Parasitic nutrition: they feed on other organism thereby
causes harm to the organism they are feeding on. In other
words, the organism does not in any way benefit from the
relationship. It is a relationship whereby an organism lives on
or inside an organism (the host) causing it a degree of harm
and absorb nutrients from the host.
d) Symbiotic nutrition: This is when two organisms live in
close association with each other for their mutual benefit in
nutrition, then the type of nutrition is known as symbiotic
nutrition. It is a type of close and long term interaction between
two biological organisms be it mutualism or commensalism.
i. Commensalism: this is a type of symbiotic nutrition whereby
one organism benefits and the other does not benefit nor is it
harmed. This type of nutrition makes it possible for the two
organisms to obtain their nutrition independently.
ii. Mutualism: in this mode of nutrition, the two organisms live
closely together and benefit from each other in nutrition. The
fungus protects the alga from drying up.
Importance of Nutrition
Nutrition is a necessity in every organism because of the
benefits gotten there from by the organism in question. Specifically,
this paper strives to consider the importance of nutrition to man. It
has enormous benefits which include but not limited to.
a) It produces heat in the body of the animal.
b) It assists in beefing up the calories need in human body.
c) It produces energy and organic building blocks for the growth
and repair of cells.
d) It facilitates the body metabolism.
e) It stores potential energy and transforms it to useable energy.
f) It controls various physiological functions of the living
organism such as movement, reproduction, excretion.
g) It serves as protection unit of the body from diseases.
h) It helps to store future food matters within the living body.
Nutrition is said to be deficient when the food that contains
all the necessary nutrients are not eaten in the right proportion.
According to World Health Organization (WHO [7]) malnutrition is
all about deficiencies, excesses, or imbalances in a person’s intake
of energy and /or nutrients. To them, there are three groups of
malnutrition as follows;
a) Undernutrition: this embraces wasting (low weight-forheight),
stunting (low height-for-age) and underweight (low
weight-for-age).
b) Micronutrient-related malnutrition : which includes
micronutrient deficiencies (a lack of important vitamins and
minerals) or micronutrient excess; and
c) Overweight : obesity and diet-related noncommunicable
diseases (such as heart disease, stroke, diabetes and some
cancers).
This results to malnutrition which have adverse effect on the health of the individual as under listed:
a) The necessary nutrients and organic materials required to
repair the body’s cells would be deficient. This would lead to
susceptibility to health risks.
b) It could lead to loss of concentration, memory and focus, the
aforementioned traits results in increased stress.
c) In younger children it could lead to poor neurological
development. This could result in cognitive impairment, poor
language development and low-problem solving skills.
d) It leads to long term growth implications resulting from
deficiencies in necessary nutrients due to poor bone
development and lack of proteins.
e) It could lead to emotional instability. Certain effects of
malnutrition are behavioural and affect the mental stability of
individuals. This could lead to emotional irregularities such as
depression, self-neglect, irritability, etc.
f) It could lead to weight loss due to depletion of body mass. This
often is accompanied by a decline in muscle function.
g) It could lead to increased risk of organ failure. This could lead
to the corresponding illnesses associated with the damages.
h) It could lead to changes in body masses, over-nutrition leads to
excess fats obstructing the proper flow of nutrients in the body
whilst under-nutrition leads to a weakened immune system.
i) It leads to stress and anxiety disorder which could escalate to
other serious mental disorder.
j) Malnourished children are more prone to die of respiratory
infections and diarrhoea [8].
k) It impairs human function at all stages of life and reduces life
expectancy.
l) Long term insufficient nutrient intake and frequent infections
can cause stunting, whose effects in terms of delayed motor
and cognitive development are largely unchangeable thus
reduces affects their brains resulting in lower IQs (Mother and
Child Health and Education Trust, [9])
m) Malnutrition increases health care costs, reduces productivity,
slows economic growth which can transform to a generic
poverty and ill-health.
n) It could result to eventual death.
There are lots of challenges facing the practice of good nutrition
which include among others; Poverty; poverty has been pinpointed
as one of the major factor that has aggravated malnutrition in
many countries of the world with Nigeria inclusive (WHO, 2021).
Similarly, listed the following as the challenges of unhealthy eating;
a) High availability of low-cost foods and beverages that are also
high in calories, fat, salt and sugar.
b) Nutrition information that is ambiguous.
c) Non-accessibility of nutritious food due to class.
In the same vein, Anderson [10] recognized five barriers to
good nutrition as listed below; lack of time, feeling overwhelmed,
lackadaisical attitude, diet confusion, feeling deprived. The scholar
asserted that people portray non-chalant attitude to ensuring they
eat right, due to many types of nutrients and the sources, people
seem confused on how to identify and access them thus falling
prey to malnutrition. In consonance with the above observations,
Anding [11] specified barriers to a healthy lifestyle to include:
a) Time: many people are so economic with time due to busy
schedule and as such prefer junk food since home prepared
food is time consuming. Yet others feel it is taking time to
reduce their weight and due to impatience retire back to their
normal eating habit.
b) Emotional eating: according to the scholar people like eating
‘comfort food’ this implies that people feed anyhow when
they are unhappy to comfort themselves and positive emotion
could also result to overeating which is not healthy when done
on daily basis.
c) Health belief: some people have personal belief on what
they eat and remain adamant to change irrespective of the
nutritional values of what is eaten.
d) Poverty and unhealthy eating: socio-economic status and
economy could dictate the mode of nutrition. Many people live
below poverty level due to massive unemployment.
e) Food, religion and culture: in this regard many religious
organization forbids eating of certain food irrespective of the
nutritional value and members are expected to oblige. The
same applies to some cultural setting where some food items
are seen as a taboo and must be avoided at all cost.
Community health services is synonymous with primary health care which came on board to leverage the members of the community of the health relation matters like sanitation, proper hygiene, prevention of communicable diseases, immunization, good nutrition and a host of others. Primary health care is essential health care based on practical, scientifically sound and socially acceptable methods and technology, made universally accessible to individuals and families in the community through their full participation and at a cost that the community and the country can afford to maintain at every stage of their development in the spirit of self-reliance and self-determination (WHO & UNICEF 1978 in University of Cape Town 2021). In congruence with the above opinion, Pharmacy Practice in Developing Countries [12] opined that primary health care is the (PCH) is the first level of contact for individuals, the family, and the community with the national health system and addresses the main health problems in the community, providing health promotion, preventive, curative and rehabilitative services accordingly. Obviously this aspect of health services is meant to get to the interior villages and impact positively on their lives and entire wellbeing.
The Principles of Primary Health Care
Primary health care strives to improve health and wellbeing
of the community members as well as curb undue illnesses that
befell them from time to time. It goes beyond delivering health
care services but covers ways of leading a healthy life and good
nutritional practices. The following are the principles of health care
services as stipulated by Victoria Order of Nurses for Canada [13]:
a) Accessibility: primary health care services are meant to
be easily accessible by the rural dwellers, it should also be
affordable and supplied to all that need it irrespective of family
socio-economic status. To be precise, it has to be universal in
approach.
b) Public or community participation: this is involvement of
the communities resources in promoting health and addressing
health issues at the grassroots level.
c) Health promotion: this is a way of helping the community
reinforce the socioeconomic circumstances that contribute to
good health.
d) Appropriate use of technology: this involves the use of
modern technological facilities in health care delivery process
to ensure effective and efficient service delivery.
e) Intersectoral collaboration: the outfit is expected to work
in partnership with the community stakeholders so as to
develop services that meet the unique needs of the individual
communities.
Components of Primary Health Care
These components of primary health care was outlined in 1978
by World Health Organization (WHO) in Laverty [14] and made
available to the member nations and espoused that these eight
essential components should serve as a means of providing health
care globally and they are.
a) Public Education: It is believed that by education the masses,
the knowledge of prevention and control of health related
problems are imbibed and utilized to avert transmissible
diseases.
b) Proper Nutrition: This is another route to good public health.
WHO works to prevent malnutrition and starvation thus
prevents many diseases and afflictions.
c) Clean water and Sanitation: a supply of clean, safe drinking
water, and basic sanitation measures regarding trash, sewage
and water cleanliness can significantly improve the health of
a population, reducing and eve eliminating many preventable
disease.
d) Maternal and Child Health Care: Another essential element
of primary health care is ensuring adequate health care to
children and to mothers, both expecting and nursing. This
requires adequate counselling on family planning and safe sex.
e) Immunization: Through the administration of global
immunizations, infectious diseases are greatly tackled and the
overall health improved globally.
f) Local Disease Control: to prevent and control local diseases
measures should be put in place to fight them as they crop up
while control measures must be explored and exhausted.
g) Accessible Treatment: this involves availability to handle
immediate health challenges from the community without
minding the cost thus reducing complications that might arise
due to delayed treatment which costs more and devastating.
h) Drug Provision: there is need to make adequate provision of
drugs both in quality and quantity to those who need them
like antibiotics for infections. This helps to curb escalating of
ailment thus makes the community safer for healthier living.
Types of Primary Health Cares
There are different types of primary health cares depending on
gravity of the ill health as outlined by Torrey (2020) namely.
a) Primary health care: this is the identification of the
symptoms of the disease and minor treatments. Ailments such
as sore muscles, broken bone, a skin rash etc.
b) Secondary health care: this is a situation whereby the primary
care giver refers one to a secondary care in which case the
patient is to be taken care of by a more specific expertise such
as cardiologists, endocrinologists, oncologists etc. according to
the affected illness.
c) Tertiary health care: this is where the patient is hospitalized
and requires a higher degree of specialty care within the
hospital, he may be referred to tertiary care. This requires
highly specialized equipment and expertise. At this stage there
is coronary artery bypass, renal or haemodialysis, plastic
surgeries or neurosurgeries. Severe burn treatments and other
complex treatment,
d) Quaternary health care: this is an extension of tertiary care
which is on a higher level for uncommon ailments that require
experimentation.
Factors Militating Against Primary Health Care Services
Primary care services just like other sectors of the economy have
so many challenges resulting to unattainable objectives. Some of
these impediments are inadequate lack of community participation,
culture and religion interference, inaccessible to safe and clean
water National Academy of Sciences [15], unsteady electricity,
ineffective communication, inadequate remuneration of the health
officers. In support of the above declaration, Okere [16] reaffirmed
that community conflict, poor administrative framework, attitude
of community members towards self-help, financial constraint and
insufficient supply of skilled and experienced field health workers
are constraints to successful health care services. In like manner,
Aregbeshola [17] opined that the barriers to adequate health care
services could be attributed to political instability, corruption,
limited institutional capacity and unstable economy are major
factors responsible for the poor development of health services
in Nigeria. The poor masses do bear the burden of dysfunctional
and ill equipped health sector which is costly for the poor to afford.
In alignment with Aregbeshola, National Academy of Sciences
[15] expressed that its accessibility and affordability are some
challenges facing the health services. Apparently, some are located
too far from some of the recipients and in case of emergency, the
worst is expected. Many others could not access the services as a
result of high cost thus restricting the beneficiaries from getting the
services as at when due. More often than not, some corrupt health
officers do hoard and sell and/or divert the materials for personal
use thereby depriving the community members the opportunity
of being served better [18]. This was observed mainly during the
sharing of medicated sleeping nets, people were caught selling
them in the market in fact, it flooded the market and that is the case
with other items meant for distribution to the masses [19]. Another
challenge was on ignorance and fake speculations as some people
do not believe in those free items shared by the health personnel,
they feel it is fake or inferior or expired because people have lost
confidence in the government [20].
Nutrition is the key to good and vibrant healthy life. This is imperative because an in-depth knowledge of the various aspects of nutrients and their sources equips the rural masses on what dictates good health and what deters good health thus better positioned to make wise choice and on time too. In the process of enlightening the masses on the good nutrition and other good health tips, the community/primary health care services come into play. For the health officers to attain great height, there is need for community participation which propels the sustainable health delivery services for the betterment of the community members thus ward off infectious diseases, infant and maternal mortality rate which has hitherto been a disaster in the interior villages.
From the above pronouncements, it is suggested as follows;
a) Government should through the appropriate agency endeavour
to supply food supplements to the rural areas to assist those
who out of poverty could not afford balanced diet.
b) The primary or community health workers should as a matter
importance sensitize the masses especially in the interior
villages on the need for proper nutrition and dangers of
malnutrition exposed so as to compel them adhere to good
nutrition habit.
c) Primary health centres should be located at every nook and
cranny of the communities so as to make it accessible for
people even in the middle of the night.
d) Health officers deserve good remuneration to make them
committed, dedicated and devoted to their job.
e) Government should deem it fit to equip the centres adequately
and more importantly make it affordable for the poor masses.
