Used to measure energy in food, amount of heart energy needed to raise temperature of 1kg of water to 1 degree celsius: carbohydrates: 4kcal/g, lipid: 9kcal/g, protein: 4kcal/g, alcohol: 7kcal/g. Micronutrients: a chemical element or substance required in trace amounts for the normal growth and development of living organisms. Provide no energy for the body but are necessary for proper functioning of the body. Very important but only good if in small amounts. Fortified: vitamins or minerals have been added to a food that (cid:449)ere(cid:374)"t origi(cid:374)ally i(cid:374) the food.
