Carbohydrates: Classification and Functions

This topic covers the fundamental classification of carbohydrates into simple sugars (monosaccharides and disaccharides) and complex carbohydrates (polysaccharides, starches, and fiber). For Zambian tertiary students in nutrition, dietetics, and food science, understanding carbohydrate structure is essential for analyzing their role in human metabolism and health. Students will learn the specific examples like glucose, fructose, sucrose, lactose, and maltose, and distinguish between digestible carbohydrates that provide energy (4 kcal/g) and indigestible dietary fiber that supports gut health. The topic connects directly to practical applications in meal planning, diabetes management, and addressing energy needs in Zambian populations. Mastery of carbohydrate classification is a foundational requirement for national diploma and degree examinations in health sciences, enabling graduates to provide accurate dietary advice and contribute to public health nutrition programs focused on energy adequacy and disease prevention.
