Esimating Size of Food Servings

The USDA's Nutrient Data Laboratory has created a table call Tips for Estimating Amount of Food Consumed in their publication "Nutritive Value of Foods"

" This table lists some handy tips to help you estimate the amount of food you eat when you cannot measure or weigh it."

Here is the table data:

Breads and grains

4-oz bagel (large): diameter of a compact disc (CD) medium piece of cornbread medium bar of soap

1 cup broccoli: light bulb
medium potato: computer mouse
1 cup raw leafy greens: baseball or fist of average adult
1⁄2 cup: 6 asparagus spears, 7 or 8 baby carrots or carrot sticks, or a medium ear of corn
