13. Water • Helps to control our body temperature, carries nutrients and waste products from our cells, and is needed for our cells to function • Involved with all body processes • Most of our body weight (60-70%) is made up of water • Drink at least 64 oz. per day • Dehydration occurs when the level of water in your body is very low • How do you know if you are drinking enough water? • Clear urine

14. Food Labels • Serving Size- the amount of food in a package. It tells you how many nutrients are in that amount of food • Daily allowances on a food label are based on a 2,000 calorie diet • Using the Percent Daily Value • Low= 5% or less of the Daily Value • Moderate= 6%-19% of the Daily Value • High= 20% or more of the Daily Value
