What Is a Serving Size?
A serving size is the recommended amount of food that is considered a single portion. Serving sizes are used in dietary guidelines, nutritional labels, and meal plans to standardize how much of a food is typically eaten at one time.
For example:
- A serving of cooked rice may be 150 grams.
- A serving of peanut butter might be 32 grams.
- A serving of meat could be 85 grams.
Serving sizes are often determined by health agencies or based on manufacturer guidelines.
