Nutrients are drawn from a wide variety of foods and the more varied your diet, the more likely you are to obtain all the nutrients you need. Energy is not a nutrient but, kilojoules (food energy) are important for providing energy for your daily activities. Protein, fats and carbohydrates are converted into energy in different quantities. Vitamins and minerals are also essential nutrients for the body, but they are not converted into energy.
