Diet

Bayani Gaba-gaba

You are what you eat, quite literally: the food in your diet supplies the energy and raw materials to build every cell. But it is not enough to eat plenty; you need the right balance of seven different nutrients. Miss out on just one, such as vitamin C or vitamin D, and a deficiency disease follows.

In this lesson you will learn what a balanced diet is, the dietary sources and importance of each nutrient (carbohydrates, fats, proteins, vitamins C and D, the mineral ions calcium and iron, fibre and water), and the causes of two classic deficiency diseases, scurvy and rickets.

Takardar Darasi

Diet links the chemistry of food molecules to human health. Examiners ask for the components of a balanced diet, the job and a food source of each nutrient, and the causes of scurvy and rickets. These are precise, learnable facts that reliably appear, and they connect to digestion, blood and bones elsewhere in the course.
