According to U.S. regulatory codes, nutrition labeling of which item is voluntary?

Nutrition labeling for raw fruit is classified as voluntary under U.S. regulatory codes. This is primarily because raw fruits are usually sold intact and are considered whole foods that do not typically contain added ingredients or nutritional modifications that would warrant label requirements. The general idea is that these foods are self-explanatory in terms of their nutritional value, and consumers can make informed choices based on their knowledge of raw fruits.

On the other hand, items like candy, dried fruit, and whole milk generally have specific labeling requirements due to added ingredients, processing, and variations in nutritional content that are not as universally understood. This differentiation reflects a regulatory approach aimed at ensuring that consumers have adequate information for items that may need more clarity regarding their nutritional aspects.
