Do Now

Create a top 10 food list that you are going to eat for the next four days. Please consider to write down calories, total calories, total fat, carbohydrates, protein, sugar, at least two vitamins. Record all these information before next Monday (Sep/19) for each food.

A Closer Look at MyPlate

MyPlate is designed to help each person develop a personal eating plan based on how many calories he or she needs.

calorie A unit of heat that measures the energy available in foods

The amount of calories your body needs is based on your age, gender, and how physically active you are.

A Closer Look at MyPlate

If you are physically active on most days, your body needs more calories than someone who is not physically active. MyPlate estimates that females between the ages of 9 and thirteen need 1,600 to 2,200 calories per day based on activity level. Males in the same age group need 1,800 to 2,600 calories per day.

A Closer Look at MyPlate

Vegetables—the Green Group: .

Fruits—the Red Group:

Dairy—the Blue Group:

Protein—the Purple Group:
