Bell Work #1 The foods we eat contain calories. What is a calorie? How many calories do you think you need a day to be healthy?

Answer A calorie is a unit of energy. In nutrition and everyday language, calories refer to energy consumption through eating and drinking and energy usage through physical activity. For example, an apple may have 80 calories, while a 1 mile walk may use up about 100 calories. Not everybody requires the same number of calories each day. The ideal number of calories we should consume depends on several factors, including our overall general health, physical activity demands, gender, weight, height, and shape. The Academy of Nutrition and Dietetics recommends that the average 13 year old boy needs 1,800 to 2,600 calories a day. The average 13 year old girl on average needs 1,800 to 2,200 calories a day.
