This comprehensive IGCSE Biology revision presentation on nutrition covers everything from balanced diets and essential nutrients to digestion and absorption. It explains the roles of carbohydrates, proteins, fats, vitamins, minerals, water, and fibre in maintaining health, and details food tests for starch, glucose, proteins, and fats. With clear diagrams and interactive activities, it guides students through key processes such as mechanical and chemical digestion, enzyme function, and nutrient absorption via the small intestine and hepatic portal vein.
