Abstract
There are increasing literature evidence and anecdotal reports worldwide on the health benefits of cocoa powder consumption. Regular consumption of cocoa powder beverage (95-100% cocoa powder) has been shown to combat malaria, diabetes and increase wellness. The study specifically established reports of some health benefits of cocoa consumption such as; increase in wellness, educational performance and alertness through consumption of cocoa powder. The study was carried out in 4 states; Ogun, Oyo, Ekiti and Osun in Southwest Nigeria. Two thousand four hundred respondents; between the ages of 10-15 years were randomly selected from the class register of 12 secondary schools and where parent negated inclusion students were substituted. They were included for daily consumption of cocoa drink for 8 weeks. Permissions were obtained from parents and the ministries of education and health. Information was solicited using key interpretative methods; Participant observers, unstructured interview, recorded video and individual class results before and after. The study revealed that 50.17% were male while 49.83% were female, the mean scores of educational performance before was 4.70 + 1.39, and 6.8 + 2.17 after. Reports from participants’ observers claimed improvement in class attendance, student educational performances; increase in wellness while 62.17% liked the taste, 64% preferred it to other drink and 81.65% like it as a daily drink. Responses were also documented from their Teachers and some parents who were persuaded for their wards inclusion wished the program be emulated by the government. It was concluded that consumption of cocoa powder and cocoa products will increase cocoa market and consequently achieve better price for cocoa farmers and combat some health challenges.

Introduction
There are increasing literature evidence and anecdotal reports worldwide on the health benefits of cocoa powder consumption. Regular consumption in dark chocolate form (≥25% cocoa powder inclusion) or as beverage (95-100% cocoa powder) has been shown to combat malaria, diabetes and hypertension. These are three of the commonest killer diseases in Nigeria. Altogether they siphon billions of naira in treatment and management costs while hundreds of thousands of Nigerians die of them annually. Numerous studies have reported a relationship between the consumption of cocoa derivatives especially dark chocolate with beneficial health effects on cardiovascular diseases as a result of the antioxidant activity of procyanidins (Keen et al 2005, Cooper et al 2008). The anti-oxidants help to fight heart diseases, overcome erectile dysfunction and sexual weakness. It lowers blood pressure, prevents malaria as well as diabetes. The presence of flavanoids in cocoa also prevents fat-like substances in the blood stream from oxidizing and clogging the arteries. The regular intake of natural cocoa powder helps to boost immunity among consumers (Olubamiwa, 2007, Akinroye, 2010 and Jayeola, et al 2011).The tropical regions produce 75% of the world’s cocoa production, only 4% of the cocoa is consumed by these regions. These regions also suffer the most from malaria, cardiovascular diseases and diabetes. There are numerous anecdotal reports and personal subjective observations of reduced episodic malaria, cardiovascular diseases and diabetes in people who daily drink natural unsweetened cocoa beverage (95-100%).
The objectives of this study are to:
- to increase local consumption of cocoa,
- develop cocoa taste in children,
- campaign for nationwide media outreach on the health benefits of cocoa powder consumption,
- Militate against glut in the international cocoa market and consequently achieve better price for cocoa farmers.
Materials and Methods
The promotion of cocoa powder consumption was carried out in four states in Nigeria as stated below:
4 Cocoa producing states = Ogun, Oyo, Ekiti and Ondo States
3 Schools/ state = 3 x 4= 12 schools
500 pupil / school = 200 x 12= 2,400 students
Schools Used
- Anglican High School, Ado-Ekiti, Ekiti- States
- Methodist Girls Grammar School, Ifaki, Ekiti- States
- Amoye Grammar School, Ikere, Ekiti- States
- Iganmode Junior Grammar School, Ota, Ogun State
- Obanta Junior Comprehensive Secondary School, Awa-Ijebu, Ogun State
- Rev. Kuti Memorial Secondary School, Isabo, Abeokuta, Ogun State

- Baptist Community School, Isokun, Oyo, Oyo State
- Lagelu Grammar School, Agugu, Ibadan, Oyo State
- New Church Grammar School, Owo, Ondo State
- St, Thomas Aquinas College, Akure, Ondo State
- Gbolugi Grammar School, Ile-Oluji, Ondo State
Selection of Study Areas & Respondents
Multi stage sampling procedure
- Stage 1 : Purposive selection of 1 geo-political zone from 6.
- Stage 2 : random selection of 4 from 6 states.
- Stage 3 : purposive selection 3 schools from each state.
- Stage 4 : random selection of 200 students from a polled register of class JSS1&2 using table of random numbers.
Permissions
Pre-visit to each state to obtain approval from the Ministry of Education was done. After approval was given, the materials needed were procured and the cocoa was processed to be sweetened for acceptability by the students. The sweetened cocoa premixes was further analyzed by Ministry of Health to ensure its safety and was certify fit for consumption before the administration of the cocoa drink to the pupils
Project Design
The project was a time series of 8 weeks based on before and after. Respondents were substituted where parents negate inclusion Information were solicited using two sets of questionnaires; before and after Jingles were made on radio stations.
Processing Into Cocoa Beverage
Pre mixes of cocoa powder and sugar were done with the help of Appetizing Food Company in order to have an homogenized products, the products was further Bagged at 3kg each sufficient to feed the students per day for a period of three months.
Chemical Analysis
The sweetened cocoa drink was analyzed for proximate analysis and mineral content was carried out using AOAC, 2000 and for microbiological assay, McFaddin, 1980 was used.
Methodology
The sweetened cocoa drink was demonstrated in schools and distributed to the students. This was done daily for a period of two months. Questionnaires were administered for the students before the commencement and after the school feeding. Active participation of media houses in the dissemination of information on the health benefits of cocoa powder consumption was also done in Oyo, Ogun, Ondo and Ekiti States.
Results and Discussion
The results in (Table 1 and 2) showed the proximate and mineral composition of both the natural cocoa powder and the sweetened cocoa beverage, while (Table 3) showed the microbial assay of the beverages; it indicated that the product is wholesome and safe for consumption. (Table 4) showed the percentage frequency of respondents personal characteristic where some of the pupils indicated that they rarely consumed the cocoa drink and some have not tasted it before despite the fact that there fathers own cocoa farms. (Table 5) showed the respondent’s wellness upon daily consumption of cocoa drinks for three months. The results indicated that the students visit to the clinic, illnesses, fever and body weakness was drastically reduced, even consumption of herbs and visits to the traditional healer were totally reduced. The Percentage representation of respondents' perception of cocoa drink was indicated in table 6, where the students affirmed that truly cocoa drink is good for their body and that they now liked the taste of cocoa which initially they are not used to.
There were positive confessions from the students, teachers and the parents on the good effect they have recorded from the day they have started drinking cocoa. Improvement in academic performance, memory retention, and decrease in absent is due to malaria attack and increase in overall wellness were among the benefits of cocoa powder consumption.

Conclusion
This project gave a landmark achievement in that it was discovered that many of the student had not gotten the opportunity to continuously take cocoa drink for such a period of time that led the student and teachers asking for more and the school becoming envy to other schools. More importantly, is the improvement recorded on their health and up scaling of the student intelligence. There had been confession from the students, teachers and parents on the positive effect recorded on the students that “cocoa drink had curbed sicknesses. Increased their intelligence and more importantly improved their attendance in schools.” Parents and teachers are now soliciting for more and to be done for the whole schools in Nigeria. From this study, Cocoa drink intake resulted to,
- Improvement on the health of the students
- Up scaling of the student intelligence.
- Regular attendance of students in schools
Recommendation
I therefore recommend that this project be repeated in other states and schools in all the cocoa producing areas in order to create likeness for the chocolate taste so as to boost the immune system and develop the unique chocolate taste into the taste buds of the pupils.
