1.0 Introduction
1.1 Background of Study
Nutrition is a fundamental pillar of human life, health and development across the entire life span. From the earliest stages of fetal development, at birth, through infancy, childhood, adolescence, and into adulthood and old age, proper food and good nutrition are essential for survival, physical growth, mental development, performance and productivity, health and well-being (FAO/WHO, 1992; World Health Organization, 2000). Evidence has shown that physical growth and cognitive development in children are faster during early years of life, and that by the age of four years, 50% of the adult intellectual capacity has been attained and before thirteen years, 92% of adult intellectual capacity is attained (Vernon, 1976).
In recent years, there has been increasing recognition of the relationship between nutrition and academic outcomes. Studies have consistently shown that children who have access to nutritious food tend to perform better academically compared to their peers who suffer from malnutrition or poor dietary habits (Glewwe & Jacoby, 1995). Nutrients such as iron, iodine, and essential vitamins are crucial for brain development and cognitive functions, including memory, attention, and problem-solving skills (Bryan et al., 2004; Grantham-McGregor et al., 2007). Despite the known benefits of proper nutrition, many children around the world, especially in low-income regions, continue to face challenges in obtaining adequate nutrition. Socioeconomic factors, food insecurity, and lack of access to healthy food options contribute to nutritional deficiencies that can adversely affect children's academic performance (Jyoti et al., 2005). This is particularly concerning given that primary school years are critical for laying the foundation for future learning and development.
Research has highlighted that specific nutritional deficiencies can have significant impacts on children's cognitive abilities. For instance, iron deficiency anemia has been linked to impaired cognitive development and lower academic achievement (Lozoff et al., 2006). Similarly, iodine deficiency, which affects thyroid function, can lead to developmental delays and decreased intellectual performance (Zimmermann, 2009). Furthermore, inadequate intake of other micronutrients such as zinc, vitamin A, and folate can also impair cognitive function and academic outcomes (Black, 2003).
The relationship between breakfast consumption and academic performance has also been a focus of research. Studies have shown that children who regularly consume a nutritious breakfast tend to have better concentration, memory, and school attendance, which collectively enhance their academic performance (Rampersaud et al., 2005). Conversely, skipping breakfast has been associated with decreased cognitive performance and poorer academic outcomes (Hoyland et al., 2009).
As the global nutrition landscape evolved, so did the research. in the late 20th and early 21st centuries, studies began to examine the impact of nutrition on academic performance in developing countries, where malnutrition rates were significantly higher. Research highlighted that children in low-income regions often faced severe nutritional deficiencies, leading to compromised cognitive abilities and poor academic outcomes (Grantham-McGregor et al., 2007). This prompted international organizations and governments to implement school feeding programs aimed at improving children's nutritional status and academic performance.
Nutrition also indirectly impacts school performance. Poor nutrition can leave students’ susceptible to illness or lead to headaches and stomachaches, resulting in school absences (Brown, Beardslee, & Prothrow-Stith, 2008). Access to nutrition that incorporates protein, carbohydrates, and glucose has been shown to improve students’ cognition, concentration, and energy levels (Bellisle, 2004; Sorhaindo & Feinstein, 2006). In contrast, nutritional deficiencies (particularly zinc, B vitamins, Omega-3 fatty acids, and protein) early in life can affect the cognitive development of school-aged children (Sorhaindo & Feinstein, 2006). Studies also suggest that diets high in trans and saturated fats can negatively impact the brain, influencing learning and memory (Gómez-Pinilla, 2008). Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the Nutritional Intake of Primary School Pupils and It’s Impact on Their Academic Performance.
1.2 Statement of Problems
Investigation revealed that despite widespread recognition of the importance of nutrition for cognitive development and academic performance, many primary school pupils continue to suffer from inadequate nutritional intake. Malnutrition and poor dietary habits remain significant issues that adversely affect children’s ability to learn and perform academically.
In many regions, particularly in low-income communities, children do not have access to the balanced and nutritious diets necessary for optimal brain function. This nutritional gap can lead to deficiencies in essential vitamins and minerals such as iron, iodine, and zinc, which are critical for cognitive processes (Black, 2003). Studies have shown that iron deficiency anemia, for instance, can impair cognitive development and reduce academic achievement (Lozoff et al., 2006). Similarly, iodine deficiency is linked to lower IQ levels and poor educational outcomes (Zimmermann, 2009).
Furthermore, socioeconomic factors exacerbate these nutritional challenges. Children from low-income families are more likely to experience food insecurity, which can lead to chronic malnutrition and hinder their academic performance (Jyoti et al., 2005). Despite efforts to address these issues through school feeding programs and nutritional interventions, the persistence of malnutrition suggests that current measures are insufficient. Another significant problem is the lack of awareness and education about the importance of nutrition among parents and caregivers. Without proper knowledge, families may not prioritize or be able to provide balanced meals, thereby perpetuating a cycle of poor nutritional habits and academic underachievement (Adelman et al., 2008).
Additionally, while some studies have explored the relationship between nutrition and academic performance, there is a need for more comprehensive and region-specific research to fully understand the extent of the problem and to develop effective interventions (Grantham-McGregor et al., 2007). Existing research often highlights the correlation between nutrition and cognitive abilities, but further investigation is necessary to identify the most impactful nutritional strategies for enhancing academic performance. The ongoing issue of inadequate nutritional intake among primary school pupils, combined with the significant impact of malnutrition on academic performance, underscores the urgent need for targeted nutritional programs, policies, and educational initiatives. Addressing these problems is essential for improving educational outcomes and ensuring that all children have the opportunity to reach their full cognitive and academic potential.

1.7 Scope of the Study
The scope of the research is focused on the Nutritional Intake of Primary School Pupils and It’s Impact on Their Academic Performance.
1.8 Limitations of the Study
One limitation of this study is the reliance on self-reported dietary intake data from primary school pupils, which may be subject to inaccuracies and biases due to memory recall and social desirability. The study is also limited by its cross-sectional design, which does not allow for the establishment of causality between nutritional intake and academic performance, only associations.
Additionally, the study may face challenges in controlling for all potential confounding variables, such as home environment, parental education levels, and socio-economic status, which can also influence academic performance. Geographic and cultural differences in dietary habits may limit the generalizability of the findings to other regions or populations.
Finally, the study's scope may be restricted by resource constraints, potentially affecting the sample size and the comprehensiveness of the nutritional assessments conducted.
