These skills will help you make a real difference in people’s health by providing accurate and professional nutrition care.
The application of nutrition knowledge is fundamental for professionals in Nutrition and Dietetics, especially in Kenya where diverse dietary challenges and health concerns prevail. Understanding basic nutritional concepts equips practitioners to assess, plan, and implement effective dietary interventions that promote health and prevent disease. This chapter lays the groundwork by defining essential nutrition terms, exploring the historical evolution of dietetics, emphasizing the importance of nutrition study, and outlining career pathways in the field. These foundations enable graduates to contribute meaningfully to Kenya’s health sector and community nutrition programs.
Nutrition is a scientific discipline that studies how food components affect the human body and influence health. For Kenyan dietitians working in hospitals, community health programs, or food industries, mastering basic nutritional concepts enables accurate assessment of nutritional status and formulation of appropriate dietary recommendations. This section clarifies key terminology that forms the language of nutrition professionals.
A clear understanding of fundamental nutrition terms is crucial for effective communication and practice in dietetics. These definitions provide a common framework for analyzing nutritional issues in Kenya’s diverse populations.
Macronutrients are nutrients required by the body in large amounts to provide energy and support bodily functions. They include carbohydrates, proteins, and fats, each serving distinct roles such as energy supply, tissue repair, and hormone synthesis. For instance, in Kenyan agricultural communities, carbohydrate-rich staples like maize and cassava are primary energy sources.
Micronutrients consist of vitamins and minerals needed in smaller quantities but essential for metabolic processes, immune function, and growth. Deficiencies in micronutrients such as iron and vitamin A are common in Kenya, contributing to anemia and vision problems respectively, especially among children and pregnant women.
Energy in nutrition refers to the capacity of food to supply the body with fuel measured in kilocalories (kcal) or kilojoules (kJ). Energy balance, the relationship between energy intake and expenditure, is critical in managing malnutrition and obesity, issues prevalent in urban and rural Kenyan settings.
Nutritional status describes the condition of an individual as influenced by nutrient intake and utilization. It is assessed through anthropometric measurements, biochemical tests, clinical signs, and dietary surveys. In Kenya, nutritionists use these assessments to identify undernutrition in children and overnutrition trends among adults.
DRIs are a set of nutrient intake values used to plan and assess diets for healthy individuals. They include Recommended Dietary Allowances (RDAs), Adequate Intakes (AIs), and Tolerable Upper Intake Levels (ULs). Kenyan dietitians adapt these values to local food availability and cultural eating patterns to ensure practical dietary guidance.

It provided an orientation to the field of nutrition and dietetics by exploring its historical development, highlighting the importance of studying nutrition for health and wellbeing, and outlining various career pathways within the discipline. The chapter also examined the roles of the nutrition care team, detailing the specific functions and responsibilities of nutritionists, dieticians, pharmacists, and nurses in promoting optimal nutritional care. Together, these topics establish a comprehensive foundation for understanding how nutrition knowledge is applied in practice to support individual and community health outcomes.
