ABSTRACT
African forests act as sources of both plant and animal foods that provide significant amounts of nutrients and
healthy boosting bioactive compounds. This study investigated the relationship between knowledge, perceptions
and socio-demographic attributes towards consumption of forest foods. A total of 279 females in charge of
decision making with respect to food preparation, were randomly selected from 12 villages in southern and
eastern Cameroon, and interviewed using researcher administered questionnaires. Multivariate logistic regression
analysis was used to identify the socio demographic factors and perceptions affecting consumption of forest
foods. Baillonella toxisperma (African pearwood) (98%), Irvingia gabonesis (bush mango) (81%) and Trichoscypha
abut (Mvout) (70%) were identified as the most nutritious foods. Among the animal forest foods, bush meat
(11%) and Imbrasia spp. (edible caterpillars) (10%) were identified as the most nutritious. Consumption of
forest foods was higher among polygamous families and also positively related to length of stay in the forest area,
as well as age of female respondents. Education had an inverse relationship with use of forest foods. Perception
towards the nutritional value of forest foods were also found to positively influence consumption of forest foods.
Since negative perceptions were found to influence consumption, there is need to invest in awareness campaigns
to strengthen the current knowledge levels among the study population.
Key Words: Consumption, indigenous foods, perceptions
RÉSUMÉ
Les forêts africaines sont des réservoirs d’aliments végétaux et animaux fournissant des quantités importantes de
nutriments et composés bioactifs stimulants naturels. La présente étude analyse la relation entre les connaissances,
les perceptions et les caractéristiques sociodémographiques de la consommation des aliments issus des forêts. Un
total de 279 femmes responsables du choix et de la préparation des aliments familiaux ont été choisis au hasard
dans 12 villages du Sud et de l’Est du Cameroun, et interviewé à l’aide de questionnaires administrés par des
chercheurs. L’analyse de régression multi-variée a été utilisée pour identifier les facteurs sociodémographiques et
les perceptions qui affectent la consommation desdits aliments. Baillonella toxisperma (Moabi) (98%), Irvingia
gabonesis (mangue sauvage) (81%) et Trichoscypha abut (Mvout) (70%) ont été identifiés comme les aliments

végétaux les plus nutritifs. Pour ce qui est des aliments forestiers d’origine animale, la viande de brousse (11%) et
Imbrasia spp. (chenilles comestibles) (10%) ont été identifiés comme étant les plus nutritifs. La consommation
des aliments issus des forêts était plus élevée parmi les familles polygames et positivement corrélée à la durée de
séjour dans la zone forestière, ainsi qu’à l’âge des femmes interrogées. Le niveau d’éducation avait une relation
inverse avec l’utilisation des aliments forestiers. La perception de leurs valeur nutritives avait également une
influence positive sur leur consommation. Étant donné que les préjugés qui ont longtemps marqués ces aliments
influencent négativement leur consommation, il est nécessaire de sensibiliser et de renforcer le niveau de connaissance
des populations étudiée sur la valeur nutritive de ces produits.

INTRODUCTION
Sub-Sahara African countries, including
Cameroon, have high prevalence of
undernutrition compared to recommended
limits of 2% for stunting and 3% for
underweight (CDHS, 2011; IFPRI, 2014).
About 33 and 15% of Cameroonian children
aged below five years, suffer from stunting
and underweight (CDHS, 2011). The stunting
and underweight rates are public health
problems in Cameroon, because they are
respectively 15 and 5 times higher, compared
to the recommended limits for stunting and
for underweight (IFPRI, 2014). The high
malnutrition rates may be attributed to the
growing negative perceptions towards
traditional foods, resulting in changes in the
food systems and dietary patterns (IFPRI,
2014; FAO, WFP and IFAD, 2014).
A shift to simplified and monotonous diets,
from the diversified traditional diets has
resulted in increased consumption of staple
foods, and a decrease in the consumption of
traditional foods including forest foods that are
abundantly and locally available within the
region (Keller et al., 2006; Frison et al., 2006;
Pingali, 2007; Penafiel et al., 2011). Negative
perceptions towards forest foods have been
documented among rural communities in
South Africa (Dweba and Mearns, 2011) and
in Togo (Akpavi et al., 2008). The adoption
of western lifestyle has also been reported to
be associated with the reduction in indigenous
knowledge on the use and preparation of
several traditional African food dishes
(Maundu, 1996; Akpavi et al., 2008).
Nutrient composition studies of forest
foods reveal that some forest food species of
plants and animals origin have high contents
of essential nutrients and bioactive compounds
(Maundu, 1996; Akpavi et al., 2008; Blaney et
al., 2009; Dweba and Mearns, 2011; Penafiel
et al., 2011; Powell et al., 2013; Fungo et al.,
2015). A recent study in south and eastern
Cameroon revealed that there is considerable
potential for forest foods to contribute to intake
of essential nutrients among consumers of
these foods (Fungo et al., 2016a). In Gabon,
forest foods contribute 36% of total vitamin A
and 20% of iron (Blaney et al., 2009), while
in Tanzania 31% of RAE (vitamin A) and 19%
of iron can be accessed in forest diets (Powell
et al., 2013). Furthermore, traditional forest
foods are usually referred to as “food for the
poor” by the educated and a section of the
elite urban residents in Africa, resulting in their
neglect (Akpavi et al., 2008; Dweba and
Mearns, 2011; Fungo et al., 2016b).
These findings are corroborated by case
studies in DR Congo among the forest
dependent communities of Kisangani (Termote
et al., 2012), the Guiziga tribe in Cameroon
(Hamawa, 2013) and populations adjoining
Lama Forest reserve in Benin (Boedecker et
al., 2014). Despite these communities having
access to abundant nutrient rich traditional
forest foods, under-nutrition and food
insecurity is rampant among them. However,
there is paucity of information on how
perceptions towards the health and nutritional
benefits from forest foods and sociodemographic factors affect consumption of
the forest foods. This study therefore, explored
Factors affecting consumption of forest foods
the relationship between knowledge,
perceptions and socio-demographic attributes
towards consumption of forest foods.
METHODOLOGY
Study area description. The study was
conducted in two sites, including one from
the East and the other from the South of
Cameroon. The geographical coordinates for
eastern site are 3.98 longitudinal and 13.18
latitude and southern site are 2.93 longitudinal
and 11.16 latitude (Noutcheu et al., 2016). The
Eastern site has a population of about 25,783
people consisting of three indigenous ethnic
groups; the Kako, the Pol and the Baka
pygmies, living in 41 villages (Medinof, 2004).
In the southern site, the population is estimated
at 79,353 consisting of almost one major ethnic
group the Bulu, living in 29 villages (Enviro
Consulting, 2009).
Selection of study districts, villages and
households. Selection of study districts,
villages and households was done using a
three-stage cluster sampling technique
composed of one stage of purposeful selection
and two stages of randomisation. The first
stage involved purposefully selecting districts
from both sites on the basis of communities
in the districts relying on the forests as a
source of livelihoods and their accessibility.
The second and third stages, involved
randomly selecting villages that are easily
accessible within the chosen two districts and
households within the selected villages. As a
result of a higher ethnic diversity in the Eastern
site, the study was conducted in seven villages
including Kouedjina (10 households), Kagnol
III (17 households), Ndembo (10 households),
Petit Pol (44 households, Melambo (23
households), Nkolbikon (16 households) and
Bonando (34 household). In the south, with
only one ethnic group, the study was
conducted in five villages, including Ngon (21
households), Bissam (39 households),
Ondondo (39 households), Methyikpwale (20
205
households) and Meyos (6 households). Two
Research Assistants (RAs) who had grown up
in the villages of the two study sites were
recruited and trained for acquaintance with the
interview schedules. The two RAs aided in
interpreting the cultural norms and meanings
of local comments expressed by respondents
during the interview.
Household sample. A total of 276
households, in the two sites was calculated
using Fisher’s (Fisher, 1998) formula below:
n = t² x p (1-p)
m²
Where:
n = required sample size, t = confidence level
at 95% (standard value of 1.96) p = 9.9%
estimated proportion of population depending
on the forests with regard to the total
population (Chao, 2012) and m = margin of
error at 5% (standard error of 0.05).
To cater for drop-outs during the data
collection process, the number of households
per site was increased by 5%. However, data
were captured from a total of 279 households
in the two sites, representing a response rate
of 92%. This sample size was about 40% of
total number of households in each village. The
inclusion and exclusion criterion of households
in the present study, included (i) households
that depended on the forests for food, (ii)
households with members that were residents
of the target areas, and (iii) households with
respondents who were healthy at the time of
recruitment.
Ethical approval and consent. Prior to
contact with the study populations, the study
proposal was presented to the Regional
Forestry Office and the Regional Health Office
in the two study regions. During the meetings,
a written permission was sought to carry out
the study. In addition to the clearance by the
Regional Forestry and Health Offices, further
206
R FUNGO et al.
permission was sought from the political
leaders at district and village levels to assist
the study gain the cooperation of the household
respondents. All standards on human and
health care ethics outlined in the Helsinki
Declaration (World Medical Association
Declaration of Helsinki, 2001) were adhered
to.
Data collection. Interviews took place at
homes of the respondents during the months
of May and June 2012, with spouses of
households. Also, women who were
household heads and had dependents were
interviewed. Women were interviewed because
they are vital in the decision making with
respect to food preparation (Becquey et al.,
2009).
Data collected included household sociodemographics, knowledge of nutritious and
healthful forest food species, uses, perceptions
and knowledge of health benefits of forest
foods. Prior to interviews, questionnaires
were pre-tested and adapted to the local
context of Cameroon.
The socio-demographic questions included
age, sex, occupation and education level of
the respondent and material used to construct
household houses. The healthful and
nutritionally important forest foods were
identified and listed by the respondents.
Respondents were also asked (i) if they knew
that malnutrition can lead to ill health, and (ii)
if they were aware that forest foods were
nutritious and healthful.
Five questions were used to assess the level
of perceptions of the respondents (Table 3),
towards the importance of forest foods to their
health. Respondents had an option of using a
narrative scale that explored the respondents’
agreement, disagreement or uncertainty.
Practices related to use of forest foods (Table
4) were assessed using four questions, with
three questions being open-ended, while one
question on number of times of preparing
forest foods having response options of
‘none’, ‘once’, ‘2-3 times’ and ‘more than 4
times’. Computation of knowledge, perception
and practices for each question, was done as
the proportion of respondents who gave an
affirmative answer.
Data analysis. All data were analysed using
the Statistical Package for the Social Sciences
(SPSS) version 21 (SPSS Inc., Chicago Ill,
USA). The Mean values were computed for
continuous variables; while proportions were
computed for the categorical variables.
Multinomial logistic regression analysis was
performed to identify the independent factors
(Table 5).
Multinomial regression analysis was
performed based on previous studies (Kimiywe
et al., 2007; Dweba and Mearns, 2011), where
two age groups of (i) <46 years which is
considered to be within the reproductive age
for women who are energetic but constrained
with the burden of baring children, and (ii)
>46 years, which is beyond the reproductive
age who have time but with diminished energy
reserves, to adequately cater for their families
were created, for comparison purposes
(Onarheim et al., 2016).
The level of significance for inclusion of
variables in the logistic regression models was
set at P<0.05, in order to have findings
comparable to similar previous studies (Chen
et al., 2003; Serra-Majem et al., 2007;
Bojorquez et al., 2015). Associations between
the independent and dependent variables were
expressed as odds ratios. A confidence interval
of 95% was used to determine significant
differences in all statistical analyses.
RESULTS
Respondent characteristics. Average age of
respondents was 44 years. The majority of
respondents had attended or completed
primary school (64%), and more than half
(56%) had 5-9 dependents (Table 1). About
75% of the households, were natives of the
study area, and therefore the knowledge and
perception they possessed could be considered

local. Despite being forest-dependent
communities about half (52%) of the
households also practiced farming.
Nutrient rich forest foods. Fruits of
Baillonella toxisperma (African pearwood)
were listed by 98% female respondents, as the
most important nutrient-rich forest foods
(Table 2). These were followed by Irvingia
gabonesis (Bush mango), Elaeis guineensis
(palm oil), Trichoscypha abut (Mvout) and
Ricinodendon heudelotii (Djansang). Among
animal foods collected from forests, bush
meat (‘gibier’) was the most consumed (11%),
followed by Imbrasia spp. (edible caterpillars),
(10%), Achatinidae spp. (snails) (6%) and
Termitoidae spp. (termites) (3%).
Perceptions towards the health benefits. A
considerable proportion of respondents
(>50%) generally expressed positive
perceptions towards some specific benefits
accrued from consuming forest foods, with
most (61%) expressing safety concerns and
health disorders related to malnutrition (Table
3). The least (10%) expression of positive
perception was registered in two sets of
respondents. This included one set of
respondents who agreed that bush meat was
nutritionally important and the second set of
respondents who believed vitamin A and iron
content in forest foods is adequate to maintain
a healthy lifestyle.

Consumption of forest foods. About 40%
of the respondents consumed forest foods
daily for their meals (Table 4). Among the
respondents that consumed forest foods, 85%
of households reported eating forest foods
once to more than 4 times daily. Preparation
of household meals was exclusively done by
women (96%); and most respondents (77%)
expressed that women were responsible for
making decisions regarding choice of foods
to be consumed for household meals.
About 69% of the respondents mentioned
that they processed B. toxisperma into edible
oil, which is a more valuable product for
household consumption and income security.
A minority of respondents mentioned
processing other valuable forest foods, notably
I. gabonesis (9%), E. guineensis l (7%), R.
heudelotii (0.4%) and P. macrophylla (0.4%).

Factors affecting consumption of forest
foods. Logistics regression analysis revealed
that female respondents aged 46 and above,
were 1.4 times more likely to prepare forest
foods (OR=1.37 95% CI 0.60 to 3.13), than
respondents aged below 46 (Table 5). On the
other hand, education had an inverse
relationship with use of forest foods. Illiterate
respondents were 6.3 folds more likely to
prepare forest foods (OR=6.26 95% CI 0.60
to 18.09) than respondents who did not
complete primary school, those who completed

primary school or secondary school.
Regarding the relationship between knowledge
and consumption of forest foods, the analysis
revealed that consumption of forest foods
significantly increased by 4 times (OR=4.02
95% CI 0.59 to 5.04) among respondents who
knew that forest foods were nutritious and by
1.1 times among (OR=1.11 95% CI 0.27 to
4.60) those that knew that poor nutrition can
lead to health disorders related to inadequate
intake of nutrients and death.
Polygamous households were more than 6
times (OR= 6.96 95% CI 0.13 to 37.24) likely
to prepare forest foods, than families that were
monogamous (Table 5). Results further
indicated that consumption of forest foods
increased with period of stay in an area. The
multivariate analysis further revealed that
respondents who expressed positive perception
towards the health and nutrition benefits of
consuming forest foods were more likely to
prepare and consume forest foods. The highest
registered likelihood of about 13 times
(OR=12.74 95% CI 1.74 to 35.82), was
registered among respondents who agreed that
forest foods can substitute for vitamin and iron
supplements (Table 5). Mothers were about
12 times more likely to prepare forest foods
(OR=12.65 95% CI 0.59 to 26.71) than their
daughters and grandmothers.
DISCUSSION
Nutrient rich forest food species. Out of
the 21 forest foods perceived by respondents
as most healthful and nutritionally important,
16 were plant based; while 5 were wild animal
sourced foods. Among the plant forest foods,
the oil producing foods (9 species) were
identified as the most important nutrient rich
and healthful forest foods. Of the nine oil
producing species, five were among the most
212
R FUNGO et al.
nutrient rich overall including; Baillonella
toxisperma (African pearwood), Irvinga
gabonensis (bush mango), Trichoscypha abut
(Mvout), Elaeis guineensis (palm oil) and
Ricinodendon heudelotii (African wood-oil
nut).
The high demand for oil producing fruits
can be attributed to their high market value in
Cameroon and neighbouring countries, such
as Nigeria and Gabon (Awono et al., 2009).
In these countries the kernels are processed
using traditional methods, to produce edible
oil that is used in household food preparation,
while the surplus is sold for income security
(Levang et al., 2014). The identified oil
producing forest foods in the present study
are also consumed as fruits. For example, the
fruits of I. gabonesis are popular among
children because of their attractive sweet
yellow pulp, as result of their high β-carotene
nutrient content (Ejiofor et al., 1987; Fungo
et al., 2015). The multipurpose use of oil
producing forest plant foods in Cameroon can
be an important reason for their conservation.
Among animal forest foods, bush meat,
Imbrasia spp. (Caterpillars) and Achatinidae
spp. (edible snails) were the most consumed
(Table 2). Bush meat provides considerable
amounts of proteins and essential
micronutrients to vulnerable communities
residing in and adjacent to forests in (Keegan,
1986; Kopper et al., 1993). Conservation
studies in Cameroon reveal that non-respect
of the wildlife legislation to protect wild life,
has resulted in unsustainable hunting of wild
animals for food (Cerutti and Tacconi, 2006;
Nasi et al., 2011; Fungo, 2016). The major
identified forest foods in Cameroon in the
present study, are similar to studies reported
in Cameroon and other Congo Basin countries
(for example, Tacconi et al., 2003; Nasi et
al., 2011; Termote et al., 2012; Hamawa,
2013; Boedecker et al., 2014).
Perceptions towards the health benefits of
forest foods. From our results, about a half
to about two thirds of the forest dependent
communities, displayed positive perceptions
towards the importance of consuming forest
foods in order to maintain a good eye sight
and the overall health (Table 3). Consumption
of forest foods is positively related to the
recognition of these foods by communities,
as healthy diets (Table 3). Forest foods were
consumed because they had health boosting
nutrients, good for eye sight and could
substitute for vitamin A and iron supplements.
The relatively higher rates of positive
perceptions towards the health benefits of
forest foods in the present study may be
attributed to the respondents being in
possession of health and nutrition information.
In Cameroon, health and nutrition information
messages are disseminated to rural mothers
and guardians at health centres during the
prenatal and post-natal visitations and vitamin
and mineral supplementation days (CDHS,
2011). Some of the respondents possessed
negative perceptions towards specific health
and nutrition benefits when forest foods were
consumed. For example, only 10% of the
respondents in the present study displayed
positive perceptions towards bush meat as
having essential nutrients to permit growth
among children (Table 3). This can be
attributed to some rural communities in
Cameroon, lacking detailed specific knowledge
concepts about the health and nutritional
benefits of forest foods. There is need to invest
in advocacy village level community nutrition
education programmes aimed at imparting
positive perceptions of forest populations by
improving their knowledge base with respect
to the health and nutrition benefits of forest
foods.
Factors that affect consumption of forest
foods. The 40% fraction of the female
respondents that used forest foods for
household meals in the present study (Table
4) was higher than what has been documented
in previous findings. For example, in DR
Congo about 30% residents of Kisangani and
Turumbu areas prepared household meals with
Factors affecting consumption of forest foods
forest foods (Termote et al., 2012). The
present study using the logistic regression
analysis, positively associated the practice of
consuming forest foods with respondents aged
46 and above, lowly educated respondents,
polygamous households, women making
decisions on which food to prepare and those
who had longer stays in the study area.
Education level of respondents was
inversely related to consumption of forest
foods in the present study (Table 5). The
present study concurs with previous studies
which revealed that educated Kenyans, South
Africans and Ugandans who earn more than
the less educated, viewed traditional and
indigenous foods as food for the poor; hence
having less preference to consume traditional
and indigenous African foods as compared to
the western processed foods (Tabuti et al.,
2004; Kimiywe et al., 2007; Dweba and
Mearns, 2011). In comparison with the
consumption levels, of the uneducated in
Kenya, South Africa and Uganda, educated
populations have been found to consume less
of wild and indigenous fruits and vegetables
(Oniang’o et al., 2003; Pelto et al., 2004;
Tabuti et al., 2004). The educated Kenyans,
South Africans and Ugandans are exposed to
influences of urbanisation and western
lifestyles, which lead to adopting negative
perceptions towards local and indigenous
African foods (Haddad, 2003; Pingali, 2007).
This has resulted in the African elites moving
away from the more diverse traditional and
indigenous diets with strong cultural identity,
to monotonously processed imported and
sometimes unhealthy diets.
An increase in the age of the respondents
positively influenced the preparation of forest
foods (Table 5). The older the household head
the better the levels of perceptions towards
nutrition and health benefits of forest foods.
The elderly have a lifetime experiences that
have shaped their individual values, habits and
preferences, motivated by convenience,
sensory appeal and perceived importance of
traditional foods to health. These findings
213
relating age with consumption of forest foods
are similar to findings elsewhere (Pelto et al.,
2004; Dweba and Mearns, 2011).
Consumption of forest foods in the present
study was considerably higher when mothers
prepared household meals, than their daughters
(Table 5). Collection and preparation of wild
and indigenous forest foods from the natural
environment, is an activity that is mostly done
by spouses of households. Children, especially
daughters in rural settings, learn from their
mothers which traditional and indigenous
foods are nutritionally superior and appropriate
to prepare. As opposed to rural women who
focus on gathering forest foods to feed their
households, household heads in urban areas
in Cameroon and elsewhere in Africa engage
more in activities that generate higher income
used to buy more of the imported refined food
than forest foods (Parsons, 1993; Rensberg
et al., 2004; Hart and Vorster, 2006; Hamawa,
2013; Levang et al., 2014).
A significant positive association was found
between respondents’ who expressed positive
perceptions towards health and nutrition
benefits of forest foods, with consumption and
preparation of forest foods (Table 5).
Specifically, the logistic regressive odds in
Table 5 reveal that consumption of forest
foods, was more than 9, 4, 6 and 3 times,
more likely to occur, among respondents who
agreed with statements; “consumption of bush
meat can make a child taller”, “forest foods
are nutritious”, “good nutrition can lead to less
ill health” and “forest foods contain nutrients
which are important for eye sight”. These
findings are in line with other literature, which
showed that having a positive perception
towards health and nutrition benefits of
indigenous and traditional foods, was a driving
force for a person to improve his/her healthful
and nutrition knowledge, practices and
behaviours (Chen et al., 2003).
A positive perception is the driving force
of a correct practice and use of certain
concepts (Sharma et al., 2008). Thus, positive
perceptions appear to be important factors that
214
R FUNGO et al.
drive correct nutrition practices. In this sense,
targeted community or village nutrition
education programmes aimed to improve
perceptions of rural forest dependent
communities need to be emphasized to policy
makers, health and forestry community
workers and development practitioners.

CONCLUSION
A number of factors, including; age, education
and marital status, perceptions towards
nutritional and health benefits of forest foods
influenced the consumption of forest foods.
Initiatives aimed at promoting consumption
of forest foods should, as a basic necessity,
aim equipping communities with information
regarding the nutrition and health benefits of
consuming forest foods. The success of such
initiatives would most likely be influenced by
a number of sociodemographic factors such
as education, sex, age and marriage status.
These factors should be taken into
consideration when planning forest foods
promotion interventions. Nutrition education
materials on the health benefits of forest foods
need to be developed and disseminated to the
forest-dwelling population. In addition, studies
relating nutrition status outcomes and links to
forest food intake need to be scaled up to
inform future interventions. Fundamentally, it
is vital to adopt strategic policies and legislation
that are sensitive to the nutritional health
benefits of forest foods in order to conserve
the bio-diversity, nutrition and development
benefits that comes along with their ecosystem.
