Researches

   (a)    Completed

1. Effects of processing methods on nutrient retention and contribution of yellow yam  

   (Dioscorea cayenensis) to nutrient intake of Nigerian consumers (December 2012)

2. Nutrient composition and bioavailability of Cirina forda (Westwood) enriched complementaryfoods (June 2013)

3. Nutrient composition and potential contribution of Winged Termites (Macrotermes bellicosus) to locally formulated nutrient-dense complementary foods

4. Effects of cooking methods on nutrient retention and micronutrient potential of pigeon pea(Cajanus cajan) (May 2015)

5. Comparative study and improving dietary diversity of Nigerians through consumption of

   three non-conventional green leafy vegetables (June 2015)

(b) In progress

1. Nutrient density and acceptability study of complementary foods enriched with Winged

   Termites (Marcrotermes bellicosus)

Most commonly used complementary foods are energy dense but low in protein, micronutrients, and plant-based, resulting in complementary foods with low biological value protein. Marcrotermes bellicosus is rich in both macro and micronutrients essential for the growth of infants and young children. Four commonly used complementary foods in Ibadan, Oyo state was enriched with powdered Marcrotermes bellicosus at various level of inclusion. Nutrient composition analysis and sensory evaluation of various preparations were carried out among the mothers of 6-23 months old children for suitability and acceptability test.

2. Nutrient density and acceptability study of complementary foods enriched with Cirina forda(Westwood)

Thenutrient composition and bioavailability of Cirina forda had been determined at 15% level of inclusion using animal model in our previous study. Complementary foods with maize and sorghum as basal material are enriched with Cirina forda and the nutrient composition analysis carried out to determine their nutrient density. Sensory evaluation will be carried out for acceptability among nursing mothers with children aged 6 – 23 months old.

Research Focus

My area of research interests are in three folds namely: food composition analysis and micronutrient potentials; dietary diversity and biodiversity through the use of wild plants and products; and the use of local foods and feedstuff in formulating nutrient-dense complementary foods to meet the nutritional needs of infants and young children.

My research in the area of food composition analysis aimed to fill the gap in knowledge and provide informed choices for consumers on the nutrient content of most indigenous staple foods in Nigeria. The major Food Composition Table in use dates back to 1968. My studies take into cognisance the processing methods and accompanied nutrient losses in locally processed foods as shown in papers. Micronutrient malnutrition is endemic worldwide, and is worst in low income countries. Therefore, I have provided information on micronutrient potentials of Nigerian indigenous foods and feedstuffs. Presence of antinutrients in foods reduce nutrient digestion, absorption and utilization, hence my publications have provided empirical data on nutrient and antinutrient composition, and effects of cooking methods on nutrient and antinutrient retention in foods. Also, I have documented the contribution of the foods/diets to nutrient requirements of their consumers, thereby assisting them in making healthy food choices in their eating habits. My publications are well referenced locally and internationally, and have been able to bridge the gap in knowledge of nutritional importance of traditional food system which are now included in Nigerian Food Composition Database. My research work on nutrient content of cassava and its products – a common staple in this environment, have also provided information which had been included in Food and Agriculture Organization database.

My research work on dietary diversity/biodiversity had brought to fore the nutrient and antinutrient content of underutilised and wildly grown plants and their products as sources of improving both dietary and biodiversity of the populace. My findings revealed promising potentials and nutrient contribution from these neglected, ‘ready to go into extinction’ species which need conservation. My studies on edible insects as source of essential nutrients (protein, minerals and vitamins) investigated their nutrient bioavailability and biosafety for consumption through animal experimentation. The edible insects can serve as source of both macro and micronutrients thereby reducing the prevalence of malnutrition among all age groups, especially in low income countries of the world. In future, the experiment will be conducted on humans.

My current research on the use of traditional feedstuffs in formulating nutrient-dense complementary foods for infants and young children has established the adequacy in nutrient density and diversity of four commonly used complementary foods in Nigeria. I have revealed the suitability of edible insects as source of animal protein, vitamin A, calcium, iron and zinc, which are essential for growth and development of infants and young children. In future, I intend to carry out intervention study on infants and young child feeding with products from these edible insects.
