Plants make their own food from sunlight, water and carbon dioxide through the process of photosynthesis. Animals cannot make their own food and need to eat plants or other animals to get energy. People also have to eat plant or animal products to get energy to grow and develop. Classification oood groups The food we eat can be grouped or classified into dierent types or groups. We call these food groups. There are a four main food groups and each food group does adierent job in the body: • Carbohydrates • Proteins • Fats and oils • Vitamins and minerals
Examples of the foods in the food groups, carbohydrates, proteins and fats and oils. We classify food according to these food groups, although most foods contain a mixture of more than one nutrient group. Let's look at each food group separately and see why each one is important: 1. Carbohydrates: • They are the most important source of energy for the body. • They store energy for the body. • Carbohydrates are an important part of the body structure. • Foods that contain carbohydrates are: pasta, samp, potatoes, cereal, mealie meal, porridge and bread.
