How To Have Healthy Portion On Your Plate
A portion is the amount of food that you choose to eat for a meal or snack. You are in charge of deciding the size of your portions.
A serving is the recommended portion size for certain foods and is used as a reference on nutrition labels. Examples include: one slice of bread or one cup (eight ounces) of juice. Serving sizes are standard for similar items. Many packages that are consumed as a single portion actually contain multiple servings!
