How to Visualize a Portion When the Serving Size Is Vague or Unclear

Vendors sometimes describe a serving as one container, one medium or one piece. Compare the food with everyday objects such as a deck of cards, a tennis ball or a measuring cup, then adjust the portion by hand or by weight. Choose grams or ounces whenever the food offers them, for the most accuracy.
