In this unit pupils should understand the content of a healthy human diet: carbohydrates, lipids (fats and oils), proteins, vitamins, minerals, dietary fibre and water, and why each is needed. Carryout calculations of energy requirements in a healthy daily diet. Understand the consequences of imbalances in the diet, including obesity, starvation and deficiency diseases. Outline the tissues and organs of the human digestive system, including adaptations to function and how the digestive system digests food (enzymes simply as biological catalysts.
