What you’ll learn

Fuel and Building BlocksDescribe carbohydrates, proteins, and fats and the main job each does.Carbohydrates give quick energy as glucose, proteins build and repair the body, and fats store energy and keep you warm. Fat holds the most energy per gram, so a healthy diet balances all three.
The MicronutrientsExplain why vitamins and minerals are needed and give examples of each.Vitamins and minerals are micronutrients needed in small amounts. Vitamins like C and A come from fruit and vegetables, while minerals like calcium and iron build bones and help blood carry oxygen.
Fibre, Water, and BalanceExplain the roles of fibre and water and describe what a balanced diet looks like.Fibre from plants keeps food moving through the gut, and water makes up two-thirds of the body and carries out countless jobs. A balanced diet supplies all seven nutrient groups in the right amounts.
