The U.S. Food and Drug Administration (FDA) revised the Nutrition Facts label in 2016, leading to several key changes in nutrient reporting. A significant update was making Vitamins A and C optional for declaration. This change was based on public health data showing that deficiencies in these vitamins are now uncommon in the American population. Manufacturers can choose to list these nutrients voluntarily, but it's not a mandatory requirement for most packaged foods.
Understanding the 2016 Food Label Updates
The FDA's revision, the first major update in over 20 years, was prompted by new scientific findings on the link between diet and chronic diseases. The aim was to make nutrition information clearer for consumers. Changes included larger text for calories and serving size, and requiring 'Added Sugars'. The list of mandatory nutrients was also updated to reflect current dietary concerns.
A Closer Look at Optional Nutrients
Manufacturers can choose to list several other nutrients voluntarily. This is often done to highlight specific health benefits or support marketing claims. Examples of optional nutrients include:
- Certain fats: While total, saturated, and trans fats are required, monounsaturated and polyunsaturated fats can be listed optionally.
- Soluble fiber: Details on soluble fiber can be added, with total dietary fiber being mandatory.
- Other carbohydrates: Sugar alcohol and other carbohydrate types can be listed for more detailed information.
- Additional vitamins and minerals: Beyond the mandatory Vitamin D, calcium, iron, and potassium, others like magnesium or zinc can be included voluntarily.
The Contrast: Mandatory vs. Optional Nutrients
To understand the label changes, it's useful to compare mandatory and optional nutrients under current FDA rules. Mandatory nutrients are those the American population often lacks, while optional ones are generally less concerning in terms of deficiency.
| Mandatory Nutrients | Previously Mandatory, Now Optional | Other Optional Nutrients | 
|---|---|---|
| Total Fat, Saturated Fat, Trans Fat | Vitamin A | Polyunsaturated Fat | 
| Cholesterol | Vitamin C | Monounsaturated Fat | 
| Sodium | Soluble Fiber | |
| Total Carbohydrate | Sugar Alcohol | |
| Dietary Fiber | Other vitamins and minerals (e.g., Magnesium) | |
| Total Sugars & Added Sugars | ||
| Protein | ||
| Vitamin D | ||
| Calcium | ||
| Iron | ||
| Potassium | 
When an 'Optional' Nutrient Becomes Required
An important exception exists for optional nutrients: they must be listed if a manufacturer makes a nutrient content claim about them. If a product claims to be a "good source of Vitamin C," then Vitamin C's amount and % Daily Value must be shown. This ensures marketing claims are supported by the nutrition panel.
Label Exemptions and the Bigger Picture
Not all foods need a nutrition facts panel. Foods like fresh produce, raw meat, and spices with minimal nutrients are generally exempt. For these, labeling is voluntary unless a specific claim is made. The evolving food label shows the FDA's effort to adapt to new science and public health needs, helping consumers make better dietary choices.
Conclusion
In conclusion, Vitamins A and C are the nutrients that became optional on the food label after the 2016 FDA update. This change was based on the fact that deficiencies are no longer widespread. Manufacturers can still voluntarily list these and other nutrients, but are only required to do so if a specific nutritional claim is made about them on the packaging. By distinguishing between mandatory and optional nutrients, the food label provides consumers with relevant information for healthier eating habits.
