Regular exercise taxes every cell and every system in your body: your muscles, joints, ligaments, tendons, respiratory, circulatory and immune systems all have to work harder when you exercise. Eating a healthy diet can help minimize the damage caused by exercise and help your body rebuild itself even stronger. Your daily diet needs to meet the tough demands of your training programme as well as keep you healthy. To help you make the right food choices, this unit explains the basis of a good training diet, what each nutrient does, how much you need and how you can achieve your ideal intake. 3.1 Sound Eating Practices What is Nutrition? And what is Nutrient? Nutrition can be defined as the science of the action of food, beverages, and their components in biological systems. A nutrient is a compound that provides a needed function in the body. Nutrients can be further classified based on the amount needed in the body. Macronutrients are the nutrients the body needs in larger amounts. Micronutrients are also important nutrients, but ones the body needs in smaller amounts. 3.1.1 Macronutrients • Carbohydrates: The word carbohydrate literally means "hydrated carbon," or carbon with water. Thus, it is no surprise that carbohydrates are made up of carbon, hydrogen, and oxygen. Sucrose (table sugar) is an example of a commonly consumed carbohydrate. Some dietary examples of carbohydrates are whole-wheat bread, oatmeal, rice, sugary snacks/drinks, and pasta.
