Reflecting Real-World Consumption Patterns
In 2016, the U.S. Food and Drug Administration (FDA) finalized sweeping changes to the Nutrition Facts label, with compliance dates beginning in 2018 for larger manufacturers. A key aspect of this overhaul was updating the listed serving sizes for many products. The core motivation for this adjustment was simple: over the decades since the label's inception, Americans' eating and drinking habits have changed significantly. The old serving sizes no longer aligned with what people were actually consuming in a single sitting.
The Science Behind the Update
Serving sizes are not recommendations for how much to eat, but rather a representation of the 'Reference Amounts Customarily Consumed' (RACCs). The FDA collected data from national food consumption surveys conducted between 2003 and 2008 to determine these new, more realistic amounts.
- Serving Size Increases: For some foods, the typical amount consumed has increased. For example, the RACC for ice cream was raised from ½ cup to ⅔ cup, and for soda, it went from 8 ounces to 12 ounces. This means if you drink a 12-ounce can of soda, you are now consuming the nutrients for a single serving, not 1.5 servings as before. For a 20-ounce bottle of soda, the entire package is now labeled as a single serving, since most people drink the whole bottle at once.
- Serving Size Decreases: Other products saw a decrease in serving size based on current consumption data. For instance, the RACC for yogurt decreased from 8 ounces to 6 ounces. This adjustment helps ensure that the nutrition information on the label accurately corresponds to how much of the product is typically eaten.
- Dual-Column Labels: To address packages that could be consumed in one or multiple sittings (e.g., a pint of ice cream or a 24-ounce soda), the FDA introduced dual-column labels. This format shows the nutritional information on both a 'per serving' and a 'per package' basis, helping consumers easily understand the total calories and nutrients if they consume the entire container.
Impact on Consumer Choices and Behavior
While the changes provide a more accurate picture of consumption, some behavioral science experts raised concerns that increasing serving sizes could unintentionally encourage some people to eat more. The risk was that if consumers perceive 'serving size' as a recommended portion, they might be influenced to consume the larger, more realistic amount, potentially undermining public health efforts to combat obesity. This highlights the importance of consumer education on how to interpret the new labels.
Comparison of Old vs. New Serving Size Labels
| Feature | Older Nutrition Facts Label | Updated Nutrition Facts Label |
|---|---|---|
| Serving Size Basis | Based on consumption data from the 1970s and 1980s, often perceived as recommended portions. | Based on current consumption data from national surveys (2003-2008) to reflect realistic amounts. |
| Serving Size Font | Standard font, smaller size, and less prominent. | Larger, bolded type for 'Serving size' and 'Calories' to emphasize this key information. |
| Example (Soda) | 8 ounces was a single serving, meaning a 20-ounce bottle was 2.5 servings. | 12 ounces is now a single serving, and a 20-ounce bottle is labeled as a single serving because people typically finish it in one sitting. |
| Example (Ice Cream) | Serving size was listed as ½ cup. | Serving size is now listed as ⅔ cup to reflect modern consumption habits. |
| Package Labeling | No requirement for dual-column labels on multi-serving, single-occasion containers. | Dual-column labels required for certain package sizes, indicating both per-serving and per-package nutritional values. |
Evolving Public Health Information
The FDA's decision to update serving sizes is part of a larger, ongoing effort to modernize nutrition information and improve public health. The new label also includes more prominent calorie counts, the addition of 'Added Sugars' to the label, and changes to the required vitamins and minerals listed. These revisions help consumers better understand the connection between their diet and chronic health issues like obesity and heart disease. The focus is on providing information that is as accurate and easy to understand as possible, allowing individuals to make more informed food choices for themselves and their families.
Conclusion
Ultimately, the update to serving sizes on the Nutrition Facts label was a necessary adjustment to reflect real-world consumption patterns in the United States. By basing serving sizes on Reference Amounts Customarily Consumed (RACCs), the FDA provides a more realistic and transparent look at the calories and nutrients in packaged foods. While adjustments to portion sizes require consumer awareness, the change is part of a broader effort to ensure food labels remain a relevant and effective tool for promoting public health. By providing clearer, bolder, and more accurate information, the new label empowers consumers to better manage their dietary intake based on how they actually eat, not how they theoretically should.
