GCSE Biology - What are Nutrients? Carbohydrates, Lipids, Proteins, Vitamins & Minerals #15

The video tutorial covers essential nutrients for a balanced diet, including carbohydrates, lipids, proteins, vitamins, minerals, fibre, and water. It explains the sources and roles of each nutrient, emphasizing the overlap in nutrient content across different foods. Carbohydrates and lipids are primary energy sources, while proteins are crucial for growth and repair. Vitamins and minerals, needed in small amounts, support various bodily functions. Fibre aids digestion, and water is vital for hydration and bodily processes.
