UNIT 2 BEING HEALTHY 2.1– WHY DO WE NEED TO EAT AND DRINK? Because we need nutrients to grow. Food gives us the nutrients our bodies need to grow. Because we need energy to live. Food gives us the energy we need to carry out our vital functions. Because we need to stay healthy. Food gives us vitamins and minerals which help us to stay healthy. Because we need water. To replace the water we lose, we need to drink water and eat foods that contain water, like fruit. We need to eat and drink because we need nutrients to grow, energy to live, to stay healthy, and water.
2.2 WHAT TYPES OF FOOD ARE THERE? Nutrition is very important. Our body gets nutrients from the food we eat. PROTEINS: Our body needs proteins to function and grow. Many parts of the body, like our organs and muscles, are formed from proteins. Meat, fish, milk and pulse vegetables contain proteins. CARBOHYDRATES AND FATS: Carbohydrates give our body energy. Fats are bad if you eat too much, but our body needs some. Flour, cereals and potatoes contain carbohydrates. Oil and butter contain fats. VITAMINS AND MINERALS: They help our body to control its functions and defend itself against illness. Vegetables and fruit contain vitamins and minerals. FIBRE: It helps our stomach to work properly. Fruits, vegetables, cereal and legume contain a lot of fibre. WATER: Our body needs water to survive. Without it, our body becomes dehydrated and eventually dies. Our body gets nutrients from the food we eat. Our body gets: carbohydrates and fats, proteins, vitamins and minerals and water.
2.3 A HEALTHY DIET. Our diet is the combination of the different foods and drinks we consume every day. Everybody needs a different diet, depending on their age and their physical activity. Children need more protein and carbohydrates than an elderly person. A marathon runner needs more energy than someone who works in an office. A healthy diet is a diet that contains the right amount of proteins, carbohydrates, fats, vitamins, minerals and water. Remember these rules: Don´t eat more than you need. Don´t eat too many fatty foods. Don´t eat too many sugary foods. Eat lots of fruit and vegetables.
2.4 FOOD PYRAMID. Food Pyramid is a visual tool that is used as a guide in designing a healthy diet. It is developed as a guide to provide a framework for the types and amounts of food that can be eaten in combination to provide a healthy diet.
