What Are Nutrients? l.Macronutrients(常量元素)：nutrients required in relatively large amounts. Provide energy to our bodies Carbohydrates,fats and oils,proteins 2.Micronutrients（微量元素)：nutrients required in smaller amounts. Vitamins and minerals

How is energy measured? We measure energy in kilojoules (KJ) or kilocalories (kcal) Kilocalorie:amount of energy required to raise the temperature of 1g of water by 1C. 1 Kcal =0.24 KJ
