Study of Serum Vitamin A, E, Lipid Profile, and Antioxidant Enzyme Activity Among School Children Consuming Groundnut Snacks in Benue State

Study of Serum Vitamin A, E, Lipid Profile, and Antioxidant Enzyme Activity Among School Children Consuming Groundnut Snacks in Benue State

Abstract

Groundnuts are a common snack among children in Benue State and are rich in fats, proteins, and bioactive compounds. However, excessive consumption may affect lipid profile and oxidative stress status. This study evaluates serum levels of vitamins A and E, lipid profile, and antioxidant enzyme activities among school children who regularly consume groundnut snacks.

A total of 150 school children aged 6–12 years were recruited from selected primary schools. Blood samples were collected and analyzed for serum vitamin A and E, total cholesterol, triglycerides, HDL, LDL, and antioxidant enzymes including superoxide dismutase (SOD) and catalase (CAT). Results indicated that regular consumption of groundnut snacks was associated with significantly higher serum vitamin E levels and improved antioxidant enzyme activities. However, some children exhibited elevated total cholesterol and LDL levels, suggesting potential risks of high lipid intake.

The study highlights the nutritional benefits of groundnut consumption, particularly in enhancing antioxidant defense. Nevertheless, moderation is necessary to prevent lipid imbalance and related health risks. Findings provide evidence for dietary guidelines targeting school children in Benue State.

CHAPTER ONE

1.0 Introduction

Dietary habits in childhood significantly influence growth, health, and biochemical status. Groundnuts are widely consumed by school children in Benue State due to their affordability and nutritional content. They contain fats, proteins, and bioactive compounds that contribute to energy intake, vitamin supply, and antioxidant defense. However, excessive consumption may alter lipid metabolism and oxidative stress markers, increasing the risk of early cardiovascular issues.

Vitamins A and E are fat-soluble nutrients with essential roles in vision, immune function, and protection against oxidative stress. Lipid profiles, including total cholesterol, triglycerides, HDL, and LDL, provide insight into metabolic health. Antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT) neutralize reactive oxygen species and protect cellular structures from damage. Monitoring these parameters in children consuming groundnut snacks is crucial for understanding the balance between dietary benefits and potential risks.

1.1 Background of the Study

Groundnuts (Arachis hypogaea) are a staple snack in many Nigerian communities, including Benue State. They provide essential nutrients, particularly fats, proteins, vitamins, and antioxidants. Regular consumption may improve antioxidant status due to the presence of vitamin E and polyphenolic compounds. Studies have shown that diets rich in antioxidants enhance SOD and CAT activity, reducing oxidative stress and supporting healthy growth.

On the other hand, excessive intake of high-fat snacks can increase serum cholesterol and LDL levels, contributing to early onset of metabolic disorders. Evaluating biochemical markers such as vitamins A and E, lipid profile, and antioxidant enzymes in children consuming groundnuts provides a comprehensive view of nutritional benefits and potential risks. Such data are essential for guiding parents, schools, and policymakers on safe dietary practices.

1.2 Statement of the Problem

Despite the known nutritional benefits of groundnuts, concerns about excessive intake and its impact on lipid metabolism and oxidative stress in children remain. In Benue State, school children often consume groundnut snacks daily without monitoring portion sizes or frequency. There is limited data on how such consumption affects serum vitamin levels, lipid profiles, and antioxidant enzyme activities in this population. Without this information, potential risks of lipid imbalance and oxidative stress may go unnoticed.

1.3 Aim and Objectives

Aim:
To evaluate the serum vitamin A, vitamin E, lipid profile, and antioxidant enzyme activity among school children consuming groundnut snacks in Benue State.

Objectives:

1. To determine serum vitamin A and E levels in children regularly consuming groundnuts.

2. To assess the lipid profile (total cholesterol, triglycerides, HDL, LDL) of the participants.

3. To evaluate antioxidant enzyme activities (SOD and CAT) in these children.

4. To identify potential health risks associated with high groundnut consumption.

5. To provide dietary recommendations for safe consumption of groundnut snacks.

1.4 Research Questions

1. What are the serum vitamin A and E levels among school children consuming groundnut snacks?

2. How does regular groundnut consumption affect lipid profile in these children?

3. What is the status of antioxidant enzyme activity in children who consume groundnut snacks regularly?

4. Are there potential health risks associated with excessive groundnut snack intake?

1.5 Significance of the Study

This study provides essential insights into the nutritional and biochemical effects of groundnut snack consumption among school children. The findings will help parents and schools balance dietary benefits against potential lipid-related risks. Moreover, the study informs public health strategies aimed at promoting healthy snack options and preventing diet-related metabolic issues in children. Finally, it contributes to scientific literature on childhood nutrition and biochemical health in Nigeria.

1.6 Scope of the Study

The research focuses on school children aged 6–12 years in selected schools within Benue State. Biochemical analyses include serum vitamin A, vitamin E, lipid profile, and antioxidant enzymes (SOD, CAT). The study investigates the impact of habitual groundnut consumption and related dietary patterns. Other lifestyle factors like physical activity are acknowledged but not extensively studied.
