A local high school has just added milk to the vending machines. Parents were very supportive of this change; however, not all the students believe this is useful. You have a few minutes to speak to the student body, and your talk should emphasize that the milk will be priced lower than the other beverages. mention that the other beverages like soda have CO2, which increases the risk for heartburn. point out that milk is a good source of calcium, which is required for teens during peak bone growth. explain how milk contains important nutrients that lower the risk for anemia, especially in teenage girls.
